Introduction. Circular external fixators are fundamental to lower limb reconstruction, primarily in situations with a high risk of infection such as open fractures. During the Covid-19 pandemic, use of circular frames in our unit decreased, following departmental approval, due to resource management and in keeping with BOA guidelines as we opted to “consider alternative techniques for patients who require soft tissue reconstruction to avoid multiple operations”. These alternatives included the use of internal fixation (plate osteosynthesis and intramedullary nailing) as a measure to reduce the number of hospital attendances for patients and to conserve resources. This change in practice has continued in part following the pandemic with the increased use of internal fixation in cases previously deemed unsuitable for such techniques. We present our experience of this treatment strategy in the management of complex lower limb injuries, focusing on outcomes and consider the lessons learnt. Materials & Methods. Data of patients with complex lower limb injuries treated before, during and after the pandemic were collected from our in-house trauma database, theatre records and follow up clinics. The rationale for choosing other techniques over a circular frame, the type of alternative technique used, the cost of such alternatives, the need for soft tissue reconstruction, time to recovery, complications and amputation rates were compared among groups. Results. These data suggest comparable outcomes between circular frames and alternative techniques can be achieved. A notable reduction in the number of circular frames applied during the review period was observed. Furthermore, frame fixation was associated with more frequent outpatient review and the associated implications for resource management. Conclusions. Conclusion: The Covid-19 pandemic has posed great challenges to the Trauma and Orthopaedic community, forcing us to be flexible by adopting alternative treatment methods to traditional circular external fixation. These alternatives have proven feasible and potentially more cost effective, prompting their adoption in the post pandemic era. However, this change of practice is not without potential consequences and continued investigation is warranted

Introduction. Ankle fractures in the elderly have been increasing with an ageing but active population and bring with them specific challenges. Medical co-morbidities, a poor soft tissue envelope and a requirement for early mobilisation to prevent morbidity and mortality, all create potential pitfalls to successful treatment. As a result, different techniques have been employed to try and improve outcomes. Total contact casting, both standard and enhanced open reduction internal fixation, external fixation and most recently tibiotalocalcaneal (TTC) nailing have all been proposed as suitable treatment modalities. Over the past five years popular literature has begun to herald TTC nailing as an appropriate and contemporary solution to the complex problem of high-risk ankle fragility fractures. We sought to assess whether, within our patient cohort, the outcomes seen supported the statement that TTC has equal outcomes to more traditional open reduction internal fixation (ORIF) when used to treat the high-risk ankle fragility fracture. Materials & Methods. Results of ORIF versus TTC nailing without joint preparation for treatment of fragility ankle fractures were evaluated via retrospective cohort study of 64 patients with high-risk fragility ankle fractures without our trauma centre. We aimed to assess whether results within our unit were equal to those seen within other published studies. Patients were matched 1:1 based on gender, age, Charlson Comorbidity Index (CCI) and ASA score. Patient demographics, AO/OTA fracture classification, intra-operative and post-operative complications, discharge destination, union rates, FADI scores and patient mobility were recorded. Results. There were 32 patients within each arm. Mean age was 78.4 (TTC) and 78.3 (ORIF). The CCI was 5.9 in each group respectively with mean ASA 2.9 (TTC) and 2.8 (ORIF). There were two open fractures within each group. Median follow up duration was 26 months. Time to theatre from injury was 8.0 days (TTC) versus 3.3 days (ORIF). There was no statistically significant difference in 30-day, one year or overall mortality at final follow up. Kaplan-Meier survivorship analysis did however demonstrate that of those patients who died post-operatively the mean time to mortality was significantly shorter in those treated with TTC nailing versus ORIF (20.3 months versus 38.2 months, p=0.013). There was no statistical difference in the overall complication rate between the two groups (46.9% versus 25%, p=0.12). The re-operation rate was twice as high in patients treated with TTC nailing however this was not statistically significant. There was no statistical difference in the FADI scores at final follow up, 72.1±12.9 (TTC) versus 67.9±13.9 (ORIF) nor post-operative mobility status. Conclusions. Within our study TTC nailing with an unprepared joint demonstrated broadly equivalent results to ORIF in the management of high-risk ankle fragility fractures; this replicates findings of previous studies. We did however observe that mean survival was significantly shorter in the TTC group than those treated with ORIF. We believe this may have been contributed to by a delay to theatre due to TTC stabilisation being treated as a sub-specialist operation in our unit at the time. We propose that both TTC and ORIF are satisfactory techniques to stabilise the frail ankle fracture however, similarly to the other fragility fractures, the priority should be on an emergent operation in a timely fashion in order to minimise the associated morbidity and mortality. Further randomised control studies are needed within the area to establish definitive results and a working consensus

Internal fixation remains the treatment of choice for non-displaced femoral neck fractures in elderly patients, whereas, arthroplasty is preferred for displaced fracture patterns. Given technological advancements in implant design and excellent long-term outcomes, arthroplasty may provide improved outcomes for the treatment of non-displaced femoral neck fractures. The aim of our study was to conduct a systematic review of the orthopaedic literature (1) to investigate the outcomes of internal fixation for the treatment of non-displaced and minimally displaced femoral neck fractures in elderly patients and (2) to compare the outcomes of patients treated with internal fixation to arthroplasty in this patient population. Relevant articles were identified using PubMed, Embase, and CENTRAL databases. Manuscripts were included only if they contained (1) patients 60 years or older with (2) nondisplaced or minimally displaced (Garden I or II) femoral neck fractures (3) treated with internal fixation or arthroplasty or (4) separately reported outcomes in this patient population. The primary outcome was reoperation. Secondary outcomes included mortality, patient reported outcomes, length of hospital stay, infection, and transfusions. An a priori decision was made to classify studies into comparative or non-comparative groups. Comparative studies directly compared arthroplasty to internal fixation in the specific study population while the non-comparative studies included separate cohorts of patients treated with arthroplasty or internal fixation. A fixed-effects model was used to quantitatively pool study outcomes. Twenty-five non-comparative studies were identified with a total of 22,020 patients, all of which were treated with internal fixation. The pooled incidence of reoperation after internal fixation was 14.4% (95% CI: 10.8 – 18.8). The incidence of mortality within one-year of injury was 14.4% (95% CI: 6.7 – 28.3), based on the reporting in 14 studies. Three comparative studies were identified with a total of 360 patients (128 treated with arthroplasty and 232 treated with internal fixation). All three studies reported reoperation rates. The overall risk of reoperation was 3.1% in the arthroplasty group compared to 9.5% in the internal fixation group (relative risk: 0.30, 95% CI: 0.10 – 0.84, p= 0.02). Only two studies reported mortality. The relative risk of mortality in patients treated with arthroplasty compared to internal fixation was 2.54 (95% CI: 1.38 – 4.70, p= 0.003). Internal fixation of minimally displaced femoral neck fractures in the elderly is associated with a risk of reoperation and mortality that exceeds 14%. Treatment with arthroplasty may reduce the risk of reoperation by 70%. However, this benefit maybe tempered by a potential increased risk of mortality associated with arthroplasty in this patient population

Introduction. Femoral shaft fractures in children is a serious injury that needs hospitalization, with a high prevalence in the age group 6–8 years old. Various treatment options are available and with a comparable weight of evidence. Submuscular plating provides a dependable solution, especially in length-unstable fractures and heavier kids. We present a novel technique to facilitate and control the reduction intraoperatively, which would allow for easier submuscular plate application. Materials and Methods. We have retrospectively reviewed four boys and three girls; all were operated in one centre. Polyaxial clamps and rods were applied to the sagittally-oriented bone screws, the reduction was done manually, and the clamps were tightened after achieving the proper alignment in the anteroposterior and lateral fluoroscopy views. The submuscular plate was applied as described, then clamps and bone screws were removed. Results. The mean age at surgery was 13 years (range, 9–14). The mean body weight was 43.3 kg (range, 30–66). There were five mid-shaft fractures, one proximal third and one distal third. There were Four type A fractures, two type B and one type C. Four patients had road traffic accidents while three had direct trauma. The mean preoperative haemoglobin concentration 12.5 g/dl (range 11.3–13 g/dl). No blood transfusion was needed intraoperatively or postoperatively. The operative time averaged 122 minutes, and the mean hospital stay was one (range 1–4 days). The patients reported no pain at a mean of 1.5 weeks (range, one-three weeks). All fractures united at a mean of 8.7 weeks (range 6–12 weeks). No wound healing problems nor deep infections happened. The knee joint range of motion was full in all patients at six weeks postoperatively. There was no mechanical irritation from the inserted plate. At the final follow-up, all fractures united without malalignment nor length discrepancy. Conclusions. External fixator-assisted internal fixation of pediatric femoral fractures would facilitate the accuracy and control of fracture reduction and allow minimally invasive percutaneous osteosynthesis. Our study has shown a decrease in operative time, and an accompanying reduction in length of inpatient stay, prolonged need for analgesia and post-operative rehabilitation

Distal radius fractures are the most common adult fractures, yet there remains some uncertainty surrounding optimal treatment modalities. Recently, the rate of operative treatment of these injuries has been increasing, however, predictors of outcomes in patients treated surgically remain poorly understood. The purpose of this study was to evaluate independent predictors of 30-day readmission and complications following internal fixation of distal radius fractures. Patients ≥18 years who underwent surgical intervention for distal radius fractures between 2005 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) using procedural codes. Patient demographics, as well as 30-day readmission, complication, and mortality rates were ascertained. Multivariable logistic regression was used to determine independent predictors of 30-day outcomes while adjusting for patient age, sex, American Society of Anaesthesiologists (ASA) class, functional status, smoking status, comorbidities, and Body Mass Index (BMI). A total of 10,051 patients were identified (average age 58 ±16). All patients received open reduction and internal fixation with no cases of external fixation identified in the data set. Included fractures were 37% extraarticular and 63% intraarticular. Within 30-days of initial fixation 143 (1.42%) patients were readmitted to the hospital, 71 patients experienced a complication, and 18 (0.18%) patients died. After adjusting for relevant covariables, current smoking increased the odds of readmission by 1.73 (95%Confidence interval [95%CI] 1.15 – 2.50), ASA class III/IV vs. I/II increased the odds of readmission by 2.74 (95%CI 1.85 – 4.06), and inpatient surgery vs. outpatient surgery increased the odds of readmission by 2.10 (95%CI 1.46 – 3.03). Current smoking also increased the odds of complications by 2.26 (95%CI 1.32 – 3.87), while ASA class III/IV increased it by 2.78 (95%CI 1.60 – 4.85), inpatient surgery increased it by 2.26 (95%CI 1.37 – 3.74), and dependent functional status increased it by 2.55 (1.16 – 5.64). In conclusion, patients with severe systemic disease, current smokers and patients undergoing inpatient surgery are at risk for 30-day readmissions and complications following operative treatment of distal radius fractures. In addition, patients with dependent functional statuses are more likely to experience a complication within 30-days

Purpose of the study:. To determine the outcomes of cases converted from an external fixator to an internal fixation device in the management of limb reconstructions and deformity corrections. Method:. A retrospective review of 18 patients, that underwent a conversion procedure to internal fixation following long term external fixation use, was done. This comprised 24 limbs. Inclusion criteria: All cases of long term external fixator use converted to internal fixation over a 5 year period. Average external fixation time, pin site care, conversion timing, surgical device used as well as outcome were documented. Results:. The mean treatment time in an external fixator was 185 days (61–370). The reasons for conversion included patient dissatisfaction, pin tract sepsis and a refracture. The conversion procedures included 8 intramedullary nail fixations and 16 plate and screw fixations. An acute conversion was identified as an internal fixation that was done in the same sitting as external fixator removal. A delayed conversion was any internal stabilisation that was done thereafter. In total, the complication rate associated with conversion to internal fixation following long term external fixation was 25%, mainly due to persistent non-union or sepsis. In the 8 conversions to intramedullary nails, 7 were acute: 4 had good outcomes with sepsis free union being achieved. 3 had poorer outcomes with a non-union and 2 amputations being documented. The single delayed nailing achieved union. In the 16 conversions to plate fixation, 13 achieved union. 10 were acute conversions and 3 were delayed. The remaining 3 that developed complications included 2 acute conversions with septic non-unions and a single delayed conversion which resulted in sepsis. Conclusion:. Conversion of an external fixator to an internal fixator in a non-acute reconstructive setting has a 75% success rate. In the acute conversion group (19 cases), plate and screw fixation had a superior outcome. In the delayed conversion group (5 cases), intramedullary fixation was favoured

Objective. Failures of internal fixation after intertrochanteric fractures pose great challenge to orthopaedic surgeons. Hip arthroplasty can be a remedy for such failures, however, the selection of femoral stem length is controversial. This study aims to report our experience of managing failed internal fixation after intertrochanteric fractures with standard femoral stem arthroplasty. Methods. A retrospective review of patients who were managed with hip arthroplasty for failed internal fixation after intertrochanteric fractures in the First Affiliated Hospital of Fujian Medical University, P.R. China between January 2001 to December 2013 was performed. Patients’ age, gender, pre- and postoperative Harris Hip Score (HHS), femoral stem types and surgical outcomes were traced and analyzed. Results. 14 patients were included. The average age at the time of internal fixation and hip arthroplasty was 74.6 years old (Range, 56–89) and 75.8 years old (Range, 58–90), respectively. The time duration between internal fixation and hip arthroplasty ranged from 3 to 26 months. 5 were total hip arthroplasty while 9 were hemiarthroplasty. 4 were implanted with long femoral stems while 10 with standard stems, including 4 cementless (SL-PLUS, Smith & Nephew)and 6 cemented stems. Standard femoral stems were defined as ones that are designed to be used in primary hip replacement, with the length of which ranging from 120 to 140mm. The distal ends of these stems did not exceed the distal screw hole levels of 2 cortical diameters. After a mean follow-up time of 6.4 years (Range, 1–13), 2 patients lost to follow-up and 2 died of non-surgically related diseases. For the 8 cases with standard stems, at the latest follow-up, no periprosthetic fractures or periprosthetic joint infections were observed. A total of 3 hip dislocations happened in 2 patients but were managed successfully with manipulative reduction followed by hip brace. The HHS score increased from an average of 35.6 preoperatively to 79.4 after surgery. Conclusions. Hip arthroplasty can be performed as revision for failed internal fixation after intertrochanteric fractures. Use of standard femoral stems is less invasive, reduces expenditure and can also achieve similar satisfactory clinical outcomes as long femoral stems. However, the long-term clinical outcomes required further follow-up

Purpose. To compare the clinical and radiological results between internal fixation using the proximal femoral nail system and bipolar hemiarthroplasty in reverse oblique intertrochanteric hip fracture in elderly patients. Materials and Methods. From January 2005 to July 2012, we reviewed 53 patients who had been treated surgically for reverse oblique intertrochanteric fracture and been followed up on for a minimum of 2 years. The patients, all over 70 years old, were divided into two groups for retrospective evaluation: one group was treated with open reduction and internal fixation using the proximal femoral nail system (31 cases), and the other group was treated with bipolar hemiarthroplasty (22 cases). Results. Early ambulation postoperatively and less pain at postoperative three months were significantly superior in the bipolar hemiarthroplasty group. However, by 24 months postoperatively, the open reduction and internal fixation group had higher Harris scores and correspondingly less pain than the bipolar hemiarthroplasty group. There were no significant differences in union rate, duration of hospitalization or lateral wall fracture healing between the two groups. Four patients in the open reduction and internal fixation group underwent reoperation. Conclusions. In the treatment of intertrochanteric fracture of the reverse oblique type, if the patient's health and bone quality are good, open reduction and internal fixation is considered to be the better choice. However, in cases of severe communition of fracture and poor bone quality along with high risk of early reduction failure, bipolar hemiarthroplasty is an alternative offering advantages in terms of early ambulation, less pain at early stages, and lower risk of reoperation

Aim. Unexpected positive infections are distinct entity in prosthetic revision surgery. The prevalence and characteristics of unexpected positive cultures in internal fixation are however less established. The aim of this study was to describe the prevalence and characteristics of unexpected diagnosis of infection in a prospective cohort of revision surgeries following internal fixation. Method. We reviewed the microbiological results following 356 surgeries that included partial or complete removal of internal fixation, performed in 328 patients (54% male, mean age 53 ± 17 years), in which infection was not initially suspected. This prospective study was performed in a large single center for musculoskeletal surgery from 2013–2017. The implants most commonly removed were plate and/or screws (281 cases, 78,9%), followed by intramedullary nails (64 cases, 18,0%). The main indications for surgery were nonunion (89 cases, 25%) and symptomatic hardware (70 cases, 19,7%). All removed implants were sonicated, and tissue cultures were obtained depending on the surgeon's criteria. Diagnosis of infection was established by the presence of 2 or more positive tissue cultures (1 with a highly virulent microorganism), or ≥ 50 colony-forming units found in the sonication fluid. Results. Infection was confirmed in 47 cases (13,2%); diagnosis was obtained with tissue cultures in 5 cases (1,4%), sonication in 14 cases (3,9%) and a combination of both sonication and tissue samples in 28 cases (7,9%). In another 24 cases (6,7%), ≥ 50 CFU of low-virulence microorganisms were isolated in the sonication fluid, but no tissue samples were available to confirm the diagnosis. Low-virulent microorganisms such as Propionibacterium acnes (22 cases / 46,8%) or coagulase-negative Staphycoccci (13 cases, 27,7%) were most commonly isolated. Sonication was key for the diagnosis of 61,7% of unexpected-positive surgeries. Nearly half of the patients received a new implant (internal fixation in 40,4%; arthroplasty in 6,4%), but only 34% of the patients were treated with antibiotics on discharge. Conclusions. Unexpected diagnosis of infection occurs in approximately 13,2% of revision surgeries following internal fixation, most commonly due to low-virulent microorganisms. Sonication was key for the diagnosis of the majority of these infections. The clinical relevance of these infections remains unclear, though the insertion of new implants raises concern. We recommend sonication of all internal fixation devices removed, especially if new implants are inserted in the revision surgery

Management of acetabular fractures in the elderly population remains somewhat controversial in regards to when to consider is open reduction internal fixation (ORIF) versus acute primary total hip. study aims to (1) describe outcome of this complex problem and investigate predictors of successful outcome. This retrospective study analyzes all acetabular fractures in patients over the age of 60, managed by ORIF at a tertiary trauma care centre between 2007 and 2018 with a minimum follow up of one year. Of the 117 patients reviewed, 85 patients undergoing ORIF for treatment of their acetabular fracture were included in the analysis. The remainder were excluded based management option including acute ORIF with THA (n=10), two-stage ORIF (n=2), external fixator only (n=1), acute THA (n=1), and conservative management (n=1). The remainder were excluded based on inaccessible medical records (n=6), mislabelled diagnosis (n=6), associated femoral injuries (n=4), acetabular fracture following hemiarthroplasty (n=1). The mean age of the cohort is 70±7 years old with 74% (n=62) of patients being male. Data collected included: demographics, mechanism of injury, Charlson Comorbidity Index (CCI), ASA Grade, smoking status and reoperations. Pre-Operative Radiographs were analyzed to determine the Judet and Letournel fracture pattern, presence of comminution and posterior wall marginal impaction. Postoperative radiographs were used to determine Matta Grade of Reduction. Outcome measures included morbidity-, mortality- rates, joint survival, radiographic evidence of osteoarthritis and patient reported outcome measures (PROMs) using the Oxford Hip Score (OHS) at follow-up. A poor outcome in ORIF was defined as one of the following: 1) conversion to THA or 2) the presence of radiographic OA, combined with an OHS less than 34 (findings consistent with a hip that would benefit from a hip replacement). The data was analyzed step-wise to create a regression model predictive of outcome following ORIF. Following ORIF, 31% (n=26) of the cohort had anatomic reduction, while 64% (n=54) had imperfect or poor reduction. 4 patients did not have adequate postoperative radiographs to assess the reduction. 31 of 84 patients undergoing ORIF had a complication of which 22.6% (n=19) required reoperation. The most common reason being conversion to THA (n=14), which occurred an average of 1.6±1.9 years post-ORIF. The remainder required reoperation for infection (n=5). Including those converted to THA, 43% (n=36) developed radiographic OA following acetabular fracture management. The mean OHS in patients undergoing ORIF was 36 ± 10; 13(16%) had an OHS less than 34. The results of the logistic regression demonstrate that Matta grade of reduction (p=0.017), to be predictive of a poor outcome in acetabular fracture management. With non-anatomic alignment following fixation, patients had a 3 times greater risk of a poor outcome. No other variables were found to be predictive of ORIF outcome. The ability to achieve anatomic reduction of fracture fragments as determined by the Matta grade, is predictive of the ability to retain the native hip with acceptable outcome following acetabular fracture in the elderly. Further research must be conducted to determine predictors of adequate reduction in order to identify candidates for ORIF

Introduction. Intracapsular hip fractures in young adults are treated with internal fixation, often as a surgical emergency to reduce the vascular insult to the femoral head. Avascular necrosis and non-union often require revision surgery. Methods. A prospective trauma database was retrospectively searched from 1. st. August 2008 to 31. st. December 2010. Intracapsular hip fracture admissions to the Regional Trauma Centre, in adults under sixty-five years, were studied. Ninety-eight intracapsular fractures internally fixed with sliding hip screw underwent radiographic review for quality of fixation, and evidence of complications at a mean of thirteen months. Co-morbid medical conditions and quality of fixation were assessed for association with revision rates. Results. Avascular necrosis developed in eighteen fractures, and seven proceeded to non-union. Seventeen of ninety-eight fractures underwent revision to total hip arthroplasty. Three individuals were deceased at final review. Six of thirty-four fractures (18%) fixed within twelve hours of injury required revision, compared with eleven of sixty-four (17%) fixed after twelve hours. None of the four fractures fixed within six hours required revision, although this was not statistically significant (p=0.32). Revision was required for three of six individuals with chronic respiratory disease (50%) excluding asthma, one of two with rheumatoid arthritis (50%), and three of six with varus reduction (50%), and each were significant on multiple regression. Residual translation and eccentric screw placement approached significance on chi-squared analysis. Only two of twenty (10%) fractures fixed using an additional anti-rotation screw required revision. Conclusions. Internal fixation of intracapsular hip fractures within twelve hours in young adults did not statistically reduce revision rates. Accurate reduction and internal fixation is paramount, and anti-rotation screws may reduce complication rates. Certain co-morbid conditions predict revision, and should be taken into consideration when selecting the primary operative procedure

Failed internal fixation of hip fracture is a problem with varied aetiology. This becomes more complex when associated with infection. Total hip arthroplasty (THA) remains the only option to restore hip biomechanics when there is partial/complete head destruction associated with it. A retrospective review was performed for 22 consecutive patients of THA following failed infected internal fixation between Sept. 2001 and Nov. 2007. There were 11 dynamic hip screw failures for intertrochanteric fractures, six failed osteotomies following proximal femoral fractures and five failed screw fixations for transcervical fractures. The average age of the patients was 48.5 years and average follow up period was 3.5 years (16 months–7.5 years). All the patients have undergone two stage revision surgeries. The average Harris Hip Score improved from 35.5 to 82.8 at the latest follow up. None of the patients had recurrence of infection. One patient developed sciatic nerve palsy, recovered partially at one year following surgery. The results were comparable to primary arthroplasty in femoral neck fractures. THA is a useful salvage procedure for failed infected internal fixation of hip fractures. Extreme care must be taken to avoid fracture and penetration of femoral shaft in such cases. Auto graft, allograft and special components like multihole cup, narrow stem should be available for reconstruction in difficult cases

Purpose. The aim of this study was to report the outcomes of a series of patients with clavicle fracture non-union who had undergone open reduction and internal fixation using a contoured locking plate without the use of distant bone graft. Methods. Patients were identified using the hospital database. Records were reviewed to determine basic demographics, operative findings, and radiological outcome. Patients were contacted and details about initial injury and treatment, and return to work and sport were recorded. Disabilities of Arm, Shoulder and Hand (DASH) for both operated and non-operated shoulders were completed. Results. 15 patients with at least 6 months follow-up (average 12.4) were identified. The average age was 39 years. All patients were initially treated in a broad arm sling. All fractures were fixed with a pre-contoured locking plate and all went on to achieve clinical and radiological union. The average DASH on the operated side was 14.5 and 4.2 on the contralateral. All patients had returned to work and regular sport activities. One patient required plate removal due to local irritation. Conclusion. The results of this small series suggest that use of distant bone graft is not necessary when performing open reduction and internal fixation for symptomatic non-union of the clavicle with appropriate preparation of fracture ends and adequate fixation

Background. Outcome of Type II and III (Sander's CT classification) fracture of the calcaneum who underwent open reduction and internal fixation was assessed. Methods. Thirty-three type II and III fractures of the calcaneum (all unilateral) underwent open reduction and internal fixation using the ‘extensile lateral approach’. There were twelve Type II and twenty-one Type III fractures. Patients were followed up for a mean of 40.81 months (Range 28 to 62 months). Patients were assessed clinically by the Creighton Nebraska Health foundation score for assessment of fractures of the calcaneum. Radiologically assessment was done comparing the pre and post operativeBohler's and Gissane angles and measuring the calcaneal width on the axial xrays. Results. Nineteen patient were classified as excellent and 14 as good. There were no poor or fair results. The mean correction of Bohler's angle was 5.6 +/− 7.2 and the Gissane'sanglecorrected by 7.8 +/−5.8 °. Superficial skin necrosis was the most common complication encountered (3 patients). Two patients preferred removal of the implant after fracture union due to prominent hardware. Conclusion. Open reduction Type II and III intra – articular calcaneal fractures is associated with minimal complications and gives reproducible results, especially in young adults

Introduction. Lateral humeral condyle fractures account for 17% of the distal humeral condyle fractures. They affect children between 5 and 10 years of age. Recent reports advocate closed reduction and internal fixation for the less displaced fractures. Methods. We retrospectively reviewed children treated with open reduction internal fixation of these fractures at a single institution over a period of 13 years. All cases of lateral humeral condyle fractures treated with ORIF were identified through the trauma register. Case notes and radiographs were retrieved. Fracture classification, mode of fixation, time to union, and clinical examination at latest follow up were reviewed. Results. 105 lateral condyle fractures were identified. 76 (72%) in boys and 29 (28%) in girls. Average age was 6.2 years. 92 were Milch type 2 and 13 Milch type 1. According to the Jacobs classification for displacement 9 were type I, 33 Type II and 63 type III. All fractures were treated with open reduction and fixation with K-wires. Average time to union (radiologic) was 34 days. Mean follow up was 39 months. Hypertrophy of the lateral condyle in follow up radiographs was documented in 45 cases (42%). Cubitus Varus was documented in 7 cases (7%). None of the children complained of painful range of movement at latest follow up. There was one case of superficial infection of the K-wires and one case of delayed union. Discussion. Open reduction internal fixation is the established management of lateral humeral condyle fractures. This series confirms the consistently good results of open reduction. Compared to recent reports of closed reduction internal fixation, this series demonstrates good results with no complications directly relating to the open reduction technique

Patellar fractures account for approximately 1% of all fractures. Open reduction and internal fixation is recommended to restore extensor continuity and articular congruity. However, complications such as nonunion and symptomatic hardware, still exist. Furthermore, there is a risk of re-fracturing of the healed bone during the removal of the implants. Magnesium (Mg), a biodegradable metal, has elastic moduli and compressive yield strength that are comparable to those of natural bone. Our previous study showed that released Mg ions enhanced fracture healing. However, Mg-based implants degrade rapidly after implantation and lead to insufficient mechanical strength to support the fracture. Microarc oxidation (MAO) is a metal surface coating that reduces corrosion. We hypothesized that Mg pins, with or without MAO, would enhance fracture healing radiologically, mechanically, and histologically, while MAO would decrease degradation of Mg pins. Patellar fracture was performed on forty-eight 18-week-old female New Zealand White rabbits according to established protocol. Briefly, the patella is osteotomized transversely and a tunnel (1.1mm) was drilled longitudinally through the two bone fragments. A pin (1 mm, stainless steel, Mg, or MAO-Mg) was inserted into the tunnel. The reduced construct was stabilized with a figure-of-eight band wire (⊘ 0.6 mm stainless steel wire). Cast immobilization was applied for 6 weeks. The rabbits were euthanized at week 8 and 12 post-operation. Microarchitecture and mechanical properties of the repaired patella were analyzed with microCT and tensile testing respectively. Histological sections of the repaired patella were stained. To evaluate the effect of the MAO treatment on degradation rate of Mg pin, the volume of the Mg pins in the patella was measured with microCT. At week 8, both Mg and Mg-MAO showed higher ratio of bone volume to tissue volume (BV/TV) than the control while there was no significant different between Mg and Mg-MAO. At week 12, Control, Mg, and Mg-MAO groups showed enlarged patella when compared to the normal patella. Tissue volume (TV) and bone volume (BV) of the patella in Mg and Mg-MAO were larger than those in the Control group. However, the Control had higher ratio of bone volume to tissue volume (BV/TV), TV density, and BV density than Mg and Mg-MAO. Tensile testing showed that the mechanical properties of the repaired patella (failure load, stiffness, ultimate strength, and energy-to-failure) of Mg and Mg-MAO were higher than that of the control at both week 8 and week 12. Histological analysis showed that there was significant new bone formation in the Mg and Mg-MAO group compared with the Control group at week 8 and 12. The degradation rate of the MAO-coated Mg pins was significantly slower than those without MAO at week 8 but no significant difference was detected at week 12. Mechanical, microarchitectural, and histological assessments showed that Mg pins, with or without MAO, enhanced fracture healing of the repaired patella compared to the Control. MAO treatment enhanced the corrosion resistance of the Mg pins at the early time point

Purpose. To perform comparative analysis between the results of internal fixation using proximal femoral nail system and bipolar hemiarthroplasty in pantrochanteric hip fracture in elderly patients. Materials and Methods. From January 2006 to February 2012, we reviewed 43 patients, who were treated surgically for pantrochanterichip fractures, with a minimum of 2 years follow up. The patient's age was older than 70 year old. The patients were divided into three groups and evaluated, retrospectively. The fracture reduction were regarded as satisfactory in S-OR-IF group(17 cases) and unsatisfactory in US-OR-IF group(9 cases) and the other group was treated with bipolar hemiarthroplasty (BHA group, 17 cases.). Results. At 24 months post-operation, S-OR-IF group had higher Harris scores, less pain, and better walking ability than S-OR-IF and BHA group. Six patients in the internal fixation group (one with S-OR-IF and five with US-OR-IF) had got reoperation. Conclusion. For pantrochanteric fractures of old-aged patient over 70 years old, bipolar hemiarthroplasty has few of severe complications which needs reoperation, and has good results of early ambulation. However, satisfactory reduction and internal fixation makes better clinical results in long term follow-up

Purpose. Limited information is available regarding the functional outcomes of radial head fractures managed with open reduction and internal fixation (ORIF). The purpose of this study was to determine the functional outcomes of radial head fractures treated with ORIF. Method. Fifty-two patients, with a mean age of 4412 years, who were treated with radial head ORIF were evaluated at a mean of 4.42.4 years. Thirty were isolated radial head fractures (Group A), 13 (Group B) were associated with a complex fracture-dislocation (terrible triad variants), and 5 (Group C) were associated with a proximal ulnar fracture (Monteggia/trans-olecranon variants). Fourty-four were partial articular fractures and 8 were complete articular fractures. Outcomes were assessed with physical and radiographic examination, and validated self-reported questionnaires. Results. The average PREE score (Patient Rated Elbow Evaluation) for Groups A, B, and C were 7.613.1, 12.313.4, and 108.5, respectively. The average MEPI (Mayo Elbow Performance Score) for Groups A, B, and C were 8913, 8511, and 918, respectively. For Groups A, B, and C respectively, the prevalence of radiographic radiocapitellar arthritis was 30%, 46%, and 20%. The average flexion/extension arc for Groups A, B, and C were 7 to 132, 6 to 134, and 10 to 132 respectively. Secondary surgery was performed in 17% of cases, most commonly for decreased motion. Three comminuted fractures failed ORIF and required conversion to radial head arthroplasty. Conclusion. Patients with radial head fractures, including those associated with complex fracture-dislocations, can achieve excellent functional outcomes with low self reported pain and disability when treated with ORIF, despite radiographic evidence of mild post-traumatic arthritis

Introduction. Hind foot Charcot deformity is a disastrous complication of diabetic neuropathy and can lead to instability, ulceration and major amputation. The treatment of these patients is controversial. Internal stabilization and/or external fixation have demonstrated variable results of limb salvage and some authorities thus advise patients to undergo elective major amputation. However, we report a series of 9 diabetic patients with severe hind foot deformity complicated by ulceration in 5/9, who underwent acute corrective internal fixation with successful correction of deformity, healing of ulceration in 4/5 patients and limb salvage in all cases. Methods. We treated 9 diabetic patients attending a multidisciplinary diabetic/orthopaedic foot clinic with progressive severe Charcot hind foot deformity despite treatment with total contact casting, 5 with predominant varus deformity and 2 with valgus deformity and 2 with unstable ankle joints. Five patients had developed secondary ulceration. All patients underwent corrective hind foot fusion with tibiotalo-calcaneal arthrodesis using a retrograde intra-medullary nail fixation and screws and bone grafting. One patient also with fixed plano-valgus deformity of the foot underwent a corrective mid-foot reconstruction. Results. Patients were followed up closely in the diabetic /orthopaedic multidisciplinary foot clinic and were treated with total contact casting. (Mean follow up time was 15.6 ±6.9months) In all patients the deformity was corrected with successful realignment to achieve a plantigrade foot. Healing of the secondary ulcers was achieved in 4/5casesand limb salvage was achieved in all cases. Three patients underwent further surgical procedure to promote bone fusion. One patient required removal of a significantly displaced fixation screw. In another patient with previously existing heel ulceration, the fixation device was removed due to progressive ulceration. However, by then, the patient had achieved fibrous union and stability of the hind foot. Two patients had postoperative wound infections which that were treated with initially intravenous antibiotic therapy and then negative pressure wound therapy. Conclusion. In conclusion, internal fixation for severe hind foot deformity together with close follow up in a multidisciplinary diabetic/orthopaedic foot clinic can be successful in diabetic patients with advanced Charcot osteoarthropathy and secondary ulceration

High-energy pelvic ring fractures are associated with polytrauma where staged surgery is recommended. While temporary skeletal stabilisation is part of the acute management, definitive care is done in a later phase. The purpose of this study was to evaluate the safety and efficacy of acute pelvic ORIF by comparing its short term outcome with those who were stabilised late. A 45-month retrospective review of the prospective pelvic fracture database of a level one trauma centre was performed. All high-energy trauma patients who were potential candidates for minimally invasive internal fixation of the pelvic ring were included. Patients were categorised as acute ORIF (<24 hrs) or late ORIF (>24 hrs). Demographics, ISS, pelvic AIS, 24 hour pack cell transfusions, physiological parameters, time to operating theatre, angiography requirement, LOS and mortality were recorded. Data was presented as mean+/−SD or percentages. Statistical significance was determined at ∗p<0.05 based on univariate analysis. Forty-three patients met inclusion criteria, seventeen patients had acute definitive ORIF (5.5 hrs to OT) and twenty-six late definitive ORIF (5 days to OT). Acute and late ORIF patients had statistically not different demographics (age: 48+/−22 years vs 40+/− 14, gender: 82% vs 79% males), injury severity (ISS: 30+/−18 vs 24.5+/−13, pelvic AIS: 3.7+/− 1 vs 3.4+/− 1.1) and 24 hour transfusion (4.7+/−5 U vs 6.6+/−4 U). Initial shock parameters were significantly worse in the acute ORIF group (∗SBP 69.7+/−17 vs 108+/−21 mmHg, ∗BD -7.35+/−4 vs -4.9+/−1.5 mEq/L, ∗Lactate 6.67+/−7 vs 2.51+/−1.3 mmol/L). Angiography was used 18% (3/17) vs 21% (6/29) of the cases. All early ORIF patients survived and one (3%) of the late ORIF patients died. The trend in shorter hospital LOS was not significant in the early ORIF group (25+/− 24 vs 37+/− 32 days) while the ICU LOS was comparable (12/17 patients with 2.9+/−2.5 days vs 15/26 patients with 3.7+/−3.6 days). Minimally invasive acute ORIF of unstable pelvic ring fractures could be performed even in severely shocked polytrauma patients. The procedure did not lead to increased rates of transfusion, mortality, ICU LOS or overall LOS. Furthermore, all these parameters showed a trend towards benefit compared to a staged approach
