Abstract

Bone defects are frequently observed in anterior shoulder instability. Over the last decade, knowledge of the association of bone loss with increased failure rates of soft-tissue repair has shifted the surgical management of chronic shoulder instability. On the glenoid side, there is no controversy about the critical glenoid bone loss being 20%. However, poor outcomes have been described even with a subcritical glenoid bone defect as low as 13.5%. On the humeral side, the Hill-Sachs lesion should be evaluated concomitantly with the glenoid defect as the two sides of the same bipolar lesion which interact in the instability process, as described by the glenoid track concept. We advocate adding remplissage to every Bankart repair in patients with a Hill-Sachs lesion, regardless of the glenoid bone loss. When critical or subcritical glenoid bone loss occurs in active patients (> 15%) or bipolar off-track lesions, we should consider anterior glenoid bone reconstructions. The techniques have evolved significantly over the last two decades, moving from open procedures to arthroscopic, and from screw fixation to metal-free fixation. The new arthroscopic techniques of glenoid bone reconstruction procedures allow precise positioning of the graft, identification, and treatment of concomitant injuries with low morbidity and faster recovery. Given the problems associated with bone resorption and metal hardware protrusion, the new metal-free techniques for Latarjet or free bone block procedures seem a good solution to avoid these complications, although no long-term data are yet available.

Abstract. Objectives. The aim of this study was to test the hypothesis that there are two different mallet injuries; specifically, tendinous ones are primarily low energy avulsion injuries whilst bony ones are primarily high-energy hyper-extension injuries. Methods. We reviewed in detail the demographics, mechanisms of injury, concomitant injuries and the radiological findings of patients presenting with bony and tendinous mallet deformities. The sizes of the bony fragments and angulation of the mallet deformities were measured on the initial radiographs using an established technique. Results. There were 62 tendinous mallet injuries (62 patients). These were mostly low energy injuries in men with a mean age of 57 years affecting primarily the middle and ring fingers. They were rarely associated with other injuries. There were 85 bony mallet injuries (83 patients). These were all high energy injuries also mostly in men with a mean age of 40 years primarily affecting the ring and little fingers. There were two double injuries and seven other concomitant injuries in the patients with bony mallet injuries. The extensor lags were a mean of 300 (range 3–590) for the tendinous injuries and 130 (range 0–380) for the bony injuries (p<0.00001). The fracture fragments were a mean of 51 (range 24–80) %; there was no correlation between fragment size and extensor lag. Conclusions. This study and review of the literature further confirm the substantial differences between tendinous and bony mallet injuries. In particular tendinous mallet injuries are avulsion injuries whilst bony mallet injuries are dorsal impaction fractures; they should be assessed and treated differently. Bony mallet injuries may be multiple and may be associated with other injuries. Low energy mallet deformities do not need radiographs

Abstract. Objectives. Identifying risk factors for inferior outcomes after anterior cruciate ligament reconstruction (ACLR) is important for prognosis and patient information. This study aimed to ascertain if BMI, pre-operative scores, demographic data and concomitant injuries in patients undergoing ACLR affected patient-reported functional outcomes. Methods. A prospective review collected data from a single surgeon series of 278 patients who underwent arthroscopic ACLR. BMI, age, gender, graft choice, pre-op Lysholm score, meniscal and chondral injuries were recorded. The Lysholm score, hop test and KT1000 were used to measure post-op functional outcome at one year. Multiple regression analysis was used to determine factors that predicted Lysholm scores at one year. Results. The mean age was 29 years, with 58 female and 220 male patients. The mean pre-op Lysholm score was 53.8. One hunded and seventy-nine patients had meniscal injuries, of which 81 were medial, 60 lateral, and 38 bilateral. Eighteen patients also had chondral injury and 106 patients had no other associated injury. Age, gender, graft type and presence of meniscal or chondral injuries did not affect one-year post-operative Lysholm scores. A BMI greater than 30, physio compliance and preoperative Lysholm scores helped predict one-year post-operative Lysholm scores (p=0.02). Pearson's correlation found a direct link between BMI and post-operative Lysholm (p=0.03). Conclusions. BMI, physio compliance and pre-operative Lysholm scores are the most significant determinants of short-term functional outcome after ACLR. However, the effects of associated injuries may be apparent in the long-term as degenerative changes set in or the continued detriment resulting from the concomitant injury affect outcome.

Tibial pilon fractures are typically the result of high-energy axial loads, with complex intra- articular fractures that are often difficult to reconstruct anatomically. Only nine simultaneous pilon and talus fractures have been published previously, but we hypothesised the chondral surface of the dome is affected more frequently. Data was acquired prospectively from 154 acute distal tibial pilon fractures (AO/OTA 43B/C) in adults. Radiographs, photographs, and intra-operative drawings of each case were utilised to document the presence of any macroscopic injuries of the talus. Detailed 1x1mm maps were created of the injuries in each case and transposed onto a statistical shape model of a talus; this enables the cumulative data to be analysed in Excel. Data was analysed using a Chi-squared test. From 154 cases, 104 were considered at risk and their talar domes were inspected; of these, macroscopic injuries were identified in 55 (52.4%). The prevalence of talar dome injury was greater with B-type fractures (53.5%) than C-type fractures (31.5%) (ρ = .01). Injuries were more common in men than women and presented with different distribution of injuries (ρ = .032). A significant difference in the distribution of injuries was also identified when comparing falls and motor vehicle accidents (ρ = .007). Concomitant injuries to the articular surface of the dome of the talus are relatively common, and this perhaps explains the discordance between the post-operative appearance following internal fixation and the clinical outcomes observed. These injuries were focused on the lateral third of the dome in men and MVAs, whereas women and fall mechanism were more evenly distributed. Surgeons who operatively manage high-energy pilon fractures should consider routine inspection of the talar dome to assess the possibility of associated macroscopic osteochondral injuries

Fibular head avulsion fractures represent a significant injury to the posterolateral corner of the knee. There is a high rate of concomitant injuries including rupture of the cruciate ligaments. Surgical fixation is indicated to restore stability, protect repaired or reconstructed cruciate ligaments and possibly decrease the likelihood of degenerative change. The current presentation describes a novel technique which provides secure fixation to the fibular head, restoring integrity of the posterolateral ligament complex and facilitating early motion. We also present a case series of our experience by a single surgeon at our tertiary referral center. Twenty patients underwent open reduction and internal fixation between 2006 and 2016 using a large fragment cannulated screw and soft tissue washer inserted obliquely from the proximal fibula to tibia. Fixation was augmented with suture repair of the lateral collateral ligament and biceps tendon. The orientation of the fracture was assessed based on preoperative imaging. Repair / reconstruction of concomitant injuries was performed during the same procedure. Early range of motion was initiated at 2 weeks postoperatively under physical therapy guidance. All patients returned for clinical and radiographic assessment (average 3.5 years). All fractures went on to bony union. There were no reoperations for recurrent instability. All patients regained functional range of motion with mean extension of 0.94 degrees and mean flexion of 121.4 degrees. Two patients underwent hardware removal. One patient developed a late local infection, which occurred greater than 5 years after surgery. Eleven patients underwent postoperative varus stress radiographs which demonstrated less than 1 mm difference between the operated and contralateral side. Fracture morphology typically demonstrated an oblique pattern in the coronal plane and a transverse pattern in the sagittal plane. This study represents a novel surgical technique for the repair of fibular head avulsion fractures with a large fragment cannulated screw placed obliquely from the fibula to tibia. Fixation is augmented with a soft tissue washer and suture repair. Our results suggest that this technique allows for early range of motion with maintenance of reduction, high rates of union, and excellent postoperative stability

Aims. To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures. Methods. Five electronic databases and three clinical trial registries were searched (January 2000 to February 2022). Trials including patients with distal tibia and/or ankle fractures without concomitant injuries were included. One reviewer conducted all searches, screened titles and abstracts, assessed eligibility, and completed data extraction; a random 10% subset were independently assessed and extracted by a second reviewer at each stage. All extracted outcomes were mapped to a modified version of the International Classification of Functioning, Disability and Health framework. The quality of outcome reporting (reproducibility) was assessed. Results. Overall, 105 trials (n = 16 to 669 participants) from 27 countries were included. Trials compared surgical interventions (n = 62), post-surgical management options (n = 17), rehabilitative interventions (n = 14), surgical versus non-surgical interventions (n = 6), and pre-surgical management strategies (n = 5). In total, 888 outcome assessments were reported across seven domains: 263 assessed body structure or function (85.7% of trials), 136 activities (68.6% of trials), 34 participation (23.8% of trials), 159 health-related quality of life (61.9% of trials), 247 processes of care (80% of trials), 21 patient experiences (15.2% of trials), and 28 economic impact (8.6% of trials). From these, 337 discrete outcomes were described. Outcome reporting was inconsistent across trials. The quality of reporting varied widely (reproducibility ranged 4.8% patient experience to 100% complications). Conclusion. Substantial heterogeneity in outcome selection, assessment methods, and reporting quality were described. Despite the large number of outcomes, few are reported across multiple trials. Most outcomes are clinically focused, with little attention to the long-term consequences important to patients. Poor reporting quality reduces confidence in data quality, inhibiting data synthesis by which to inform care decisions. Outcome reporting guidance and standardization, which captures the outcomes that matter to multiple stakeholders, are urgently required. Cite this article: Bone Jt Open 2022;3(10):832–840

Chauffeur fractures or isolated radial styloid fractures (IRSF) are known to be associated with scapholunate ligament (SL) injuries. Diagnosis without arthroscopic confirmation is difficult in acute fractures. Acute management of this injury with early repair may prevent the need for more complex reconstructive procedures for chronic injuries. We investigated if all IRSF should be assessed arthroscopically for concomitant SL injuries. We performed a prospective cohort study on patients above the age of 16, presenting to the Gold Coast University Hospital with an IRSF, over 2 years. Plain radiographs and computerized tomography (CT) scans were performed. All patients had a diagnostic wrist arthroscopy performed in addition to an internal fixation of the IRSF. Patients were followed up for at least 3 months post operatively. SL repair was performed for all Geissler Grade 3/4 injuries. 10 consecutive patients were included in the study. There was no radiographic evidence of SL injuries in all patients. SL injuries were identified arthroscopically in 60% of patients and one third of these required surgical stabilisation. There were no post operative complications associated with wrist arthroscopy. We found that SL injuries occurred in 60% of IRSF and 20% of patients require surgical stabilisation. This finding is in line with the literature where SL injuries are reported in up to 40-80% of patients. Radiographic investigations were not reliable in predicting possible SL injuries in IRSF. However, no SL injuries were identified in undisplaced IRSF. In addition to identifying SL injuries, arthroscopy also aids in assisting and confirming the reduction of these intra-articular fractures. In conclusion, we should have a high index of suspicion of SL injury in IRSF. Arthroscopic assisted fixation should be considered in all displaced IRSF. This is a safe additional procedure which may prevent missed SL injuries and their potential sequelae

Background. Anterior cruciate ligament (ACL) reconstruction with concomitant meniscal injury occurs frequently. Meniscal repair is associated with improved long-term outcomes compared to resection but is also associated with a higher reoperation rate. Knowledge of the risk factors for repair failure may be important in optimizing patient outcomes. Purpose. This study aimed to identify the patient and surgical risk factors for meniscal repair failure, defined as a subsequent meniscectomy, following concurrent primary ACL reconstruction. Methods. Data recorded by the New Zealand ACL Registry and the Accident Compensation Corporation, the New Zealand Government's sole funder of ACL reconstructions and any subsequent surgery, was reviewed. Meniscal repairs performed with concurrent primary ACL reconstruction was included. Root repairs were excluded. Univariate and multivariate survival analysis was performed to identify the patient and surgical risk factors for meniscal repair failure. Results. Between 2014 and 2020, a total of 3,024 meniscal repairs were performed during concurrent primary ACL reconstruction (medial repair = 1,814 and lateral repair = 1,210). The overall failure rate was 6.6% (n = 201) at a mean follow-up of 2.9 years, with a failure occurring in 7.8% of medial meniscal repairs (142 out of 1,814) and 4.9% of lateral meniscal repairs (59 out of 1,210). The risk of medial failure was higher in patients with a hamstring tendon autograft (adjusted HR = 2.20, p = 0.001), patients aged 21–30 years (adjusted HR = 1.60, p = 0.037) and in those with cartilage injury in the medial compartment (adjusted HR = 1.75, p = 0.002). The risk of lateral failure was higher in patients aged ≤ 20 years (adjusted HR = 2.79, p = 0.021) and when the procedure was performed by a surgeon with an annual ACL reconstruction case volume of less than 30 (adjusted HR = 1.84, p = 0.026). Conclusion. When performing meniscal repair during a primary ACL reconstruction, the use of a hamstring tendon autograft, younger age and the presence of concomitant cartilage injury in the medial compartment increases the risk of medial meniscal repair failure, whereas younger age and low surgeon volume increases the risk of lateral meniscal repair failure

Introduction. Acetabular fractures are a challenging problem. It has been published that outcome is dependent upon the type of fracture, the reduction of the fracture and concomitant injuries. The end-points of poor outcome include avascular necrosis of the femoral head, osteoarthritis. However, we lack definitive statistics and so counselling patients on prognosis could be improved. In order to achieve this, more outcome studies from tertiary referral centres are required. We present the first long term follow up from a large tertiary referral centre in Ireland. Methods. We identified all patients who were ten years following open reduction and internal fixation of an acetbular fracture in our centre. We invited all of these patients to attend the hospital for clinical and radiographic follow-up. As part of this, three scoring systems were completed for each patient; the Short-form 36 health survey (SF36), the Merle d'Aubigné score and the Short Musculoskeletal Functional Assessment (SMFA). Results. The data represents one year's activity at a new tertiary referral unit. We identified a total of 44 patients who were ten years following ORIF of acetabular fractures in our unit. 21 patients (48%) replied to written invitation and attended the hospital for clinical and radiographic follow-up. A further 7 patients were contacted by telephone and interviewed to gauge their rehabilitation. 3 patients had passed away. The remaining 13 patients were not contactable. Of those who attended in person for follow-up; 18 were male and 3 were female. The mean age at follow-up was 40.5 years (Range 27-60). In terms of fracture pattern epidemiology, 43% of patients sustained posterior column and wall fractures, 29% posterior wall, 14% posterior column alone, 9.5% transverse with posterior wall and 9.5% bicolumnar. 2 patients in the follow-up group had total hip replacements. Of the remaining patients the overall mean SF36 score was 78.8% (SD 16.4). The mean SMFA was 14.1% (SD 5). The mean Merle d'Aubigné score was 14.9 (SD 3.2) with 63% graded as good or excellent. Comparison of outcome between sub-groups according to fracture classification showed no significant difference. Traumatic sciatic nerve injury was sustained by four patients in the follow-up group and all patients continued to complain of ongoing weakness. Of the patients who were contacted via telephone, 2 had total hip replacements. The remaining 5 reported no significant problems with their hips and cited this as the reason for not attending follow-up. Conclusion. Overall the outcome of the patients was more favourable than expected. This was supported by the results of the clinical scoring systems. In some patients this also appeared to be despite poor radiographic findings. Our observations suggest that concomitant injuries, especially sciatic nerve injury have a profound negative influence on the patients' ability to fully rehabilitate. These data provide a valuable tool for the trauma surgeon in providing the patient with an educated prognosis

Background: There is no consensus on the best treatment of complex intraarticular fractures and high energy diaphyseal fractures of the long bones. The Locking Compression Plate (LCP) and the Less Invasive Stabilization System (LISS) are the new implants with angular stability developed by the AO/ASIF. The new screw-plate systems seem to offer an excellent alternative for the operative fixation in these cases. Patients and methods: In a prospective study the new system was used to treat 20 patients (8 women, 12 men; average age 39.3 yrs) with 23 high – energy injuries (multifragmentary shaft fractures or complex intraarticular) from december 2001. During a mean period of 20 (13–30) months, complications, clinical and radiographic findings were followed prospectively. One patient was lost to follow-up. 19 patients underwent a standardized follow-up examination. According to the AO classification, 6 were proximal tibial fractures 41-C; 4 distal tibial 43-C; 6 distal femoral 33-C; 3 humerus 12-C and 4 distal radius 23-C. Ten of the fractures were open, 6 grade II, and 4 grade III. Because of severe concomitant injuries, 4 fractures were first treated with an external fixator and definitively stabilized more than two weeks after the injury. 2 patients were operated on after failure of others implants and non-union. Results: The outcome correlated with the severity of the fracture, anatomic reduction, exact positioning of the plate and concomitant injuries. Despite the large number of open and comminuted fractures no serious complications as deep infections, vascular lesions, DVT or non-unions were presented. Conclusions: We found the new internal fixator system to be a safe and reliable procedure. The new system offers numerous fixation possibilities and has proven its worth in complex fracture situations and in revision operation. A good knowledge of biomechanics is essential as well as precise preoperative planning

Objectives: The comminuted supracondylar femur fractures are resulted from high energy trauma. Infection and union problems are common complications. LISS is a new generation implant leading to decrease these complications. The aim of this prospective study is to compare the outcomes of distal femoral fractures treated by LISS (Less Invasive Stabilization System) of the multiple injured and isolated fractured cases. Patients and Methods: This prospective study comprised of twentysix patients, sixteen men and ten women, who had 27 distal femoral fractures. Patients were divided as having multiple injury (group I) or isolated femur distal fractures (group II). There were fourteen supracondylar (AO type A) and thirteen intercondylar (AO type C) fractures. The average Injury Severity Scores (ISS) of group I and II were 26.7 and 9 respectively. Operations were performed according to biological fixation principles by means of submuscular manner. No grafting was performed to enhance the healing. The cases were evaluated based on the criteria of Schatzker–Lambert and modified Hospital for Special Surgery (HSS) scoring system. Results: The mean hospitalization time was 16 days (range 13–46) in GI mainly depended on the presence of concomitant injuries and 8 days (range 6–12) in GII. The mean age of the patients was 49 years (range 26–80) (51.6 in GI and 45.6 in GII). The mean follow up period was 25.8 months. Union was achieved in all cases. Two cases required debridement procedures due to deep infection in group I. One of them healed completely but the other not resulted in chronic ostemyelitis. Revision surgery was carried out in one case due to screw pull out at second weeks postoperatively. The average range of knee motion of the group I and II at the last control were 112.8°, 121.8 respectively. The mean modified HSSs were 73.9 and 79.9 respectively. There was no significant difference for HSS scores and range of knee motion (p> 0.05). Based on the criteria described by Schatzker and Lambert, the outcomes were assessed as excellent in 3 cases, good in 8, fair in 3, and poor in 2 in GI and as excellent in 3, good in 7 and fair in 1 in GII. Poor results of GI were because of osteomyelitis in one case and 15° varus deformity in another. The full weight bearing time was longer in group II depending on the concomitant injuries. Conclusion: We concluded that LISS is effective method to yield satisfactory results for comminuted supracondylar fractures with multi trauma, even if their final results seem to be lower in comparison to isolated femur fractures

Purpose of study. To review the treatment and outcomes of paediatric pelvic ring injuries in the UK. Methods and results. We performed a retrospective review of all pelvic fracture admissions to an English paediatric major trauma centre (MTC) from 2012 to 2016. A total of 29 patients were admitted with pelvic ring injuries with a mean age of 11 years (4- 16yrs). Road traffic accident was the mechanism in majority (72%), followed by fall from height (24%). Femoral shaft fracture was present in 5 (17%), head injury in 5 (17%), chest injuries in 5 (17%) and bladder injury in one child. 48% patients needed surgical procedures for fractures or associated injuries. We differentiated injuries according to the classification system of Torode and Zeig. 17% were Type A, 3% Type B, 48% Type C and 31% Type D. Almost all (93%) patients were treated conservatively. 51% of patients were allowed to mobilize full weight bearing after a period of bed rest. Non-weight bearing mobilization was recommended for fractures extending into the acetabulum, sacral fractures, unstable fracture patterns or associated fractures (neck of femur, femoral shaft and tibial shaft). Surgical fixation occurred in two patients. Both of these patients had significantly displaced Type D fractures. Only 44% of patients were back to sports at six months. Conclusions. Pelvic ring injuries are rare within the paediatric population and are associated with a high incidence of concomitant injury and significant functional morbidity. Their treatment should involve a multidisciplinary approach, which includes specialist in the care of pelvic trauma

Introduction. The stability of the elbow joint following an acute elbow dislocation is dependent on associated injuries. The ability to identify these concomitant injuries correctly directs management and improves the chances of a successful outcome. Interpretation of plain radiographs in the presence of either a dislocation or post-reduction films with plaster in-situ is difficult. This study aimed to assess the ability of orthopaedic registrars to accurately identify associated bony injuries on initial plain radiographs using CT as the gold standard for comparison. Methods. Patients over the age of 16 years undergoing an elbow CT scan within one week of a documented elbow dislocation between 1st June 2010 and 1st June 2014 were included in the study. Three orthopaedic registrars independently reviewed both the initial dislocation and immediate post reduction plain radiographs to identify any associated bony injuries. This radiograph review was repeated by each registrar after two weeks. The incidence of associated injuries as well as the inter- and intra-observer variability was calculated. Results. 28 patients were included in the study. 54% of the patients were female and the mean age was 45 years (range 16 to 90 years). The incidence of a radial head fracture was 54%, coronoid fracture 43% and epicondyle avulsion 18% on CT. The inter-observer reliability was only shown to be fair amongst registrars and the intra-observer variability moderate. Conclusions. Computerised tomography is a useful adjunct in the assessment of associated osseous injuries following an elbow dislocation due to the presence of a high number of injuries. Plain radiographs alone have been shown to have only a fair and moderate inter and intra-observer variability respectively, therefore a low threshold to obtain further 3D imaging should be practised.

Introduction: Distal radial volar locking plating systems (DRVLP) are commonly used for complex fractures of the distal radius in all ages. There have been few studies in the current literature that analyse the success of volar locking plating systems. Those studies with functional outcome and complications data have yet to be. The purpose of the study is assess whether the surgeon can predict which fractures will have a good versus a poor outcome in terms of clinical, radiological and functional outcome assessment. Method: Patients who sustained a distal radial fracture managed with a radial volar locking plate were identified from hospital audit data systems, after appropriate research ethical approval. Retrospective data was collected on all patients from patient case notes, radiographs performed pre- and postoperatively and functional data by completed patient rated wrist evaluation scores (PRWE). Demographic, clinical, radiographic and functional data was collected and statistically analysed by a bio-statistician. Results: 153 patients were included (116 female, 38 male). Patients were included from all 11 surgeons at the Geelong Hospital between November 2004 and February 2008. The age range was 17 to 91 years. Average age was 53.7 years at time of injury. 24% patients had concomitant other injuries. In terms of AO fracture classification 53% patients had type C1 – C3 fractures. 147 patients had the AO Synthes DRVLP, 6 patients had other volar locking plate systems. 27% patients had an exogenous bone graft insertion. The major complication rate was 12% (18/153) with 94% of these cases requiring further surgery. Post operative radiographs demonstrated an average increase in ulnar variance by 1.25mm, radial inclination by 7 deg, radial length by 4mm and radial tilt by 16 deg (volar angulation) compared to pre-operative radiographs that was statistically significant. 90% patients returned a PRWE form and. Discussion: Predictive parameters for a poor functional outcome were: men, dominant hand injury, other concomitant injuries, pre operative reduced inclination and volar tilit & high ulnar variance on radiographs. Poor functional outcome correlated with poor radiological outcome

Rib fractures (RF) represent the most common bone fracture after blunt trauma, occurring in 10–20% of all trauma patients and leading to concomitant injuries of the inner organs in severe cases. However, a standardized classification system for serial rib fractures (SRF) does still not exist. Basic knowledge about the facture pattern of SRF would help to predict organ damage, support forensic medical examinations, and provide data for in vitro and in silico studies regarding the thoracic stability. The purpose of our study was therefore to identify specific SRF patterns after blunt chest trauma. All SRF cases (≥3 subsequent RF) between mid-2008 and end of 2015 were extracted from the CT database of our University Hospital (n=383). Fractures were assigned to anterior, antero-lateral, lateral, postero-lateral, and posterior location within the transverse plane (36° each) using an angular measuring technique (reliability ±2°). Rib level, fracture type (transverse, oblique, multifragment, infracted), as well as degree of dislocation (none, </≥ rib width) were recorded and each related to the cause of accident. In total, 3747 RF were identified (9.7 per patient, ranging from 3 (n=25) to 33 (n=1)). On average, most RF occurred in crush/burying injuries (15.9, n=13) and pedestrian accidents (12.2, n=14), least in car/truck accidents (8.8, n=76). Altogether, RF gradually increased from rib 1 (n=140) towards rib 5 (n=517) and then decreased towards rib 12 (n=49), showing a bell-shaped distribution. More RF were detected on the left thorax (n=2027) than on the right (n=1720). Overall, most RF were found in the lateral (33%) and postero-lateral (29%) segment. Posterior RF mostly occurred in the lower thorax (63%), whereas anterior (100%), antero-lateral (87%), and lateral (63%) RF mostly appeared in the upper thorax. RF were distributed symmetrically to the sagittal plane, showing a hotspot (up to 98 RF) at rib levels 4 to 7 in the lateral segment and rib level 5 in the antero-lateral segment. In the car/truck accident group, 47% of all RF were in the lateral segment, in case of frontal collision (n=24) even 60%. Fall injuries (n=141) entailed mostly postero-lateral RF (35%). In case of falls >3 m (n=45), 48% more RF were detected on the left thorax compared to the right. CPR related SRF (n=33) showed a distinct fracture pattern, since 70% of all RF were located antero-laterally. Infractions were the most observed fracture type (44%), followed by oblique (25%) and transverse (18%) fractures, while 46% of all RF were dislocated (15% ≥ rib width). SRF show distinct fracture patterns depending on the cause of accident. Additional data should be collected to confirm our results and to establish a SRF classification system

The purpose of our study was to evaluate several specific methods of skeletal stabilisation and soft-tissue treatment of open fractures in the orthopaedic department in a district hospital. After stabilisation of the patient and diagnosis of concomitant injuries, the basic initial evaluation of the fracture type, soft-tissue laceration, and neurovascular status is made. Deformities of the legs are realigned promptly. Sterile wound dressing and early intravenous administration of antibiotics are applied. Prophylaxis against tetanus is considered. Radiograph diagnostics are made and the Tscherne, Gustilo and Anderson classifications of open fractures are used. All devitalised tissue is removed in the operating theatre. The following methods of bone stabilisation are used: immobilisation in a cast, external fixation, and intramedullary nailing. Repeated debridement of soft-tissue is carried out. Postoperatively, time duration for bone-healing and deep infections were analysed. During the past five years, 159 patients with a tibial shaft fracture were treated. Twenty-six were open fractures Type I (8), Type II (9), Type IIIA (7), and Type IIIB (2). Methods of stabilisation were cast (5), external fixation (7) and intramedullary rod (14). Deep infection in Type III fractures was reported in two cases and a non-union in one case. Bone grafting was performed in two cases. Nailing followed short-term use of an external fixator in three cases. No amputations were necessary. The average time (in months) for union was 5 (Type I), 5.8 (Type II), and 8 (Type III). Our experience agrees with the principle that the method of choice is intramedullary nailing that may follow the short-term use of an external fixation. Open fractures of the tibial shaft represent a limb-threatening and potentially life-threatening emergency. Optimum treatment involves appropriate initial evaluation, the administration of antibiotics, urgent operative debridements, skeletal stabilisation, and early soft-tissue closure or flap-coverage. The type of treatment depends on the individual characteristics of the fracture and the concomitant soft-tissue injury. Fractures with a higher degree of comminution and soft-tissue laceration have more complications

This study investigated athletes presenting with grade II syndesmosis injuries and identified the clinical and radiological factors important in differentiating a stable from dynamically unstable injury and those findings associated with a longer recovery and return to sport. Sixty-four athletes were prospectively assessed with an average follow-up of 37 months (range 24–66 months). Athletes with an isolated distal syndesmosis (+/− medial deltoid ligament) injury were included. Those athletes with a concomitant ankle fracture were excluded. Those considered stable (grade IIa) were treated conservatively with a boot and progressive rehabilitation. Those with clinical signs of instability underwent arthroscopy and if instability was confirmed (grade IIb) the syndesmosis was stabilized surgically. The clinical assessment of injury to individual ligaments of the ankle and syndesmosis were recorded along with MRI findings, complications and time to return to play. All athletes returned to the same level of professional sport – 28 with IIa injuries returned at a mean of 45 days whereas the 36 with grade IIb injuries returned to play at a mean of 64 days (p< 0.001). Clinical assessment of injury to the ligaments of the syndesmosis correlated well with MRI findings. Those with a positive squeeze test were 9.5 times as likely and those with a deltoid injury 11 times more likely to have an unstable syndesmosis confirmed arthroscopically. The combination of injury to the AITFL and deltoid ligament was associated with a delay in return to sport. Concomitant injury to the ATFL indicated a different mechanism of injury with the syndesmosis less likely to be unstable and was associated with an earlier return to sport. Clinical and MRI findings may differentiate stable from dynamically unstable grade II injuries and identify which athletes may benefit from early arthroscopic assessment and stabilization. It also suggests the timeframe for expected return to play

Acetabular fractures, particularly in the geriatric population are on the rise. A recent study indicated a 2.4-fold increase in the incidence of acetabular fractures, with the fastest rising age group, those older than the age of 55. Controversy exists as to the role and indications for total hip arthroplasty (THA), particularly in the acute setting. Three common scenarios require further evaluation and will be addressed. 1.) What is the role of THA in the acute setting for young patients (< 55 years old)? 2.) What is the role and indications for THA in the older patient population (>55 years) and what are surgical tips to address these complex issues? 3.) What are the outcomes of THA in patients with prior acetabular fractures converted to THA?. Acetabular fractures in young patients are often the result of high energy trauma and are a life changing event. In general, preservation of the native hip joint and avoidance of arthroplasty as the first line treatment should be recommended. A recent long-term outcome study of 810 acetabular fractures treated with Open Reduction and Internal Fixation (ORIF) demonstrated 79% survivorship at 20 years with need for conversion to THA as the endpoint. Risk factors for failure were older age, degree of initial fracture displacement, incongruence of the acetabular roof and femoral head cartilage lesions. In selected younger patients, certain fracture types with concomitant injuries to articular surfaces may best be treated by acute THA. In the elderly patient population, acetabular fractures are more likely the result of low energy trauma but often times result in more displacement, comminution and damage to the articular surface. Osteoporosis and generalised poor bone quality make adequate reduction and fixation a challenge in these acute injuries. As such, the role of acute arthroplasty is becoming more widespread. Consideration should be given to delayed arthroplasty in certain patients to allow time for fracture healing followed by THA. However, early mobilization and weight bearing is important in the elderly population and consideration should be given to acute THA. The challenge remains gaining appropriate acetabular fixation in the fractured, osteoporotic bone. Early results showed high complication rates with acetabular fixation. However, newer fixation surfaces and advances in ORIF techniques have led to improved results. In addition, the need for complex acetabular reconstruction with the use of cages or cup cage constructs may be required in this setting. Appropriate 3-D imaging is essential to evaluate the extent of involvement of the anterior and posterior columns as well as the acetabular walls. Mears et al. reported on 57 patients who underwent THA for acute acetabular fracture and reported results at a mean of 8.1 years. 79% of patient reported good or excellent results and no acetabular cups were revised for loosening. One of the more common scenarios is the patient that presents with a prior ORIF of an acetabular fracture that has developed post-traumatic arthritis or avascular necrosis of the hip and requires conversion to THA. Challenges in this patient population include dealing with prior hardware that may interfere with THA component fixation, severe stiffness of the joint making exposure difficult and prior heterotopic ossification that may put neurovascular structures at risk. Previous studies have demonstrated lower long-term survivorship of the acetabular component (71% at 20 years) compared to primary THA for osteoarthritis. New acetabular fixation surfaces should mitigate the risk of aseptic loosening in this challenging patient population
