Objectives. Distal humerus fractures in elderly population are often comminuted and presents multiple challenges. When managed with fixation the results are often complicated with stiffness, pain, and reduced function while total elbow replacement is fraught with lifelong restrictions on load bearing which can significantly affect elderly patients who rely assistive devices for ambulation. Elbow hemiarthroplasty however, presents a viable alternative in these cases. This series evaluates the results of the distal humerus hemiarthroplasty in a single centre. Designs and methods. Data was collected retrospectively. Comprehensive case reviews were done to collect demographic, intra-operative and post-operative data. Fractures were classified as per AO classification. The primary outcome was functional outcome and range of motion (ROM). The secondary outcomes were complications and patient satisfaction. Results. 22 cases were included in this study from 2016 – 2023 majority being females (n=18). Mean age was 74years (SD −11.2). Majority fractures were AO type C3 (n=15) with two A2 type fractures managed for non-union. Pre-existing bone on bone arthritis was present in 3 cases and CT scan was done for 12 patients to assess fracture configuration. Excluding those treated for non- union the median time between fracture and surgery was 8.5 days. Follow-up of more than 6 months was available for 16 patients with median follow-up of 18 months. ROM was available for 17 patients with 13 (50%) patients having functional ROM. No patients had full extension and there was a mean lag of 20. 0. Mean flexion was 118.2. 0. Nearly 2/3. rd. patients (73%- n=16) were satisfied with the surgery with no problems in activity of daily living. Complications seen were ulnar neuropathy (n=3), heterotopic ossification(n=2) and periprosthetic fracture (n=1). Conclusion. This single centre study suggests good outcomes following distal humerus hemiarthroplasty. It is a reasonable alternative to fixation and total elbow arthroplasty in complex fractures

The aim of this study was to establish any association between implant cut-out and a Tip Apex Distance (TAD), ≥25mm, in proximal femoral fractures, following closed reduction and stabilisation, with either a Dynamic Hip Screw (DHS) or Intramedullary Hip Screw (IMHS) device. Furthermore, we investigated whether any difference in cut-out rate was related to fracture configuration or implant type. WE conducted a retrospective review of the full clinical records and radiographs of 65 consecutive patients, who underwent either DHS or IMHS fixation of proximal femoral fractures. The TAD was measured in the standard fashion using the combined measured AP and lateral radiograph distances. Fractures were classified according to the Muller AO classification. 35 patients underwent DHS fixation and 30 patients had IMHS fixation. 5 in each group had a TAD≥25mm. There were no cut-outs in the DHS group and 3 in the IMHS group. 2 of the cut-outs had a TAD≥25mm. The 3 cut-outs in the IMHS group had a fracture classification of 31-A2, 31-A3 and 32-A3.1 respectively. In addition, the fractures were inadequately reduced and fixed into a varus position. A TAD<25mm would appear to be associated with a lower rate of cut-out. The cut-out rate in the IMHS group was higher than the DHS group. Contributing factors may have included an unstable fracture configuration and inadequate closed fracture reduction at the time of surgery

Background. This is an epidemiological study of patients with middle third clavicle fractures presenting to a tertiary hospital. The data is used to formulate a classification system for middle third clavicle fractures based on fracture configuration and displacement. Description of methods. Patients presenting primarily to a referral hospital with middle third clavicle fractures were identified using the PACS radiology system. The radiographs were reviewed to determine the fracture type, displacement, shortening and amount of comminution. The clinical notes of each patient were reviewed to determine the mechanism of injury, soft tissue status, neurovascular status and treatment rendered. A novel classification system was developed to describe the different fracture configurations seen in the group. The interobserver and intraobserver correlation of the classification system as well as the ability of the classification system to predict treatment were tested. Summary of results. Three hundred and three patients were included in the review, 223 males and 80 females. Middle third clavicle fractures were displaced in 69% of cases. Displaced fractures tend to have a significant amount of displacement and shortening in most cases with averages of 19.64mm (Std Dev. 6.901) and 19.15mm (Std Dev. 9.616) respectively. Acceptable interobserver and intraobserver correlation levels were shown for the proposed classification system. Conclusion. The epidemiology of middle third clavicle fractures found in the population studied differs substantially from first world populations. It underlines the high level of road traffic accidents and interpersonal violence seen in South Africa. Surgeons treating clavicle fractures are still divided on the indications for surgery with little correlation found between the fracture type and displacement on radiographs and the type of treatment rendered. The classification system provides guidelines to treating surgeons to the correct treatment modality. MULTIPLE DISCLOSURES

Whilst the use of reverse total shoulder arthroplasty is becoming more common for the treatment of rotator cuff arthropathy, there is still relatively little evidence with regards to its use in complex fractures of the proximal humerus in the elderly. It is increasingly felt to be of use in those patients in whom either internal fixation is not possible due to fracture configuration or bone quality, or in whom there is a rotator cuff deficiency. We report the outcomes of 14 patients with complex 3- or 4-part humeral fractures or delayed presentation of dislocation treated with reverse TSR. Patients were treated within a two year period from January 2011 to December 2013. The average age at time of operation was 75 (50–91 years) with a mean follow-up of 7 months (2–13 months). One patient moved out of area and one lost to follow-up two months following procedure. Reverse TSR was considered a salvage procedure for patients with comminuted proximal humeral fractures or those who presented with irreducible non-acute dislocations. At time of last follow-up all 14 patients were satisfied with the results of their operation and functionally independent with activities of daily living. Range of movement post-operatively was good with mean active forward extension 97° (70–150°) and abduction 101° (80–170°). 43% of patients were pain-free, whilst the remainder only required the use of occasional analgesia. No major post-operative complications were reported. Patients who underwent reverse TSR for dislocation fared better than for those with proximal humeral fractures. The mean active forward extension was 107.5° (90–150°) and abduction 112.5° (90–170°) in the dislocation group (n=5) compared with those who had a fracture in which the forward extension was 91.4° (70–120°) and abduction 95° (80–120°). The results of these patients demonstrate that reverse TSR should be considered in patients with complex proximal humeral fractures or delayed presentation of fractures. It seems to provide consistently excellent pain-relief for patients, with patients either reporting being pain-free or requiring only occasional analgesia. In addition, all patients treated were functionally independent following operation. Range of movement, particularly for those with dislocation, appear good. Further follow-up is required to ensure sustained results but early studies are encouraging

Introduction. The use of reverse total shoulder arthroplasty (RSA) is becoming increasingly common in the treatment of rotator cuff arthropathy. In recent years indications for use have expanded to include elderly patients in whom either internal fixation is not possible due to fracture configuration, poor bone quality, or presence of a rotator cuff deficiency. There is however relatively little evidence to support its use in these circumstances. Objective. This study aims to assess the viability of RSA as a salvage procedure in the treatment of complex proximal humeral fractures or irreducible dislocations, quantified in terms of functional outcome, complication rates and patient reported satisfaction. Methods. All patients presenting between January 2011 and December 2013 with a complex 3- or 4-part humeral fracture or a delayed presentation with an irreducible non-acute dislocation, treated with salvage RSA were eligible for inclusion. All operations were performed in a single centre by one of two specialist upper limb surgeons. Standard deltopectoral approach was performed. Tournier reverse fracture stem with two choices of inserts and graft hole in the stem with proximal hydroxyapatite coating was the implant of choice. All patients and underwent a standardised rehabilitation programme. Clinical outcome was measured at final follow up using (1) patient reported satisfaction, (2) clinician measured range of movement (3) complication rate. Results. A total of 16 patients were eligible for inclusion in this study. Mean age at time of operation was 72.8 years (41–91 years) with a mean follow-up of 7 months (2–13 months). At time of last follow-up 100 per cent of patients were satisfied with the results of their operation and functionally independent with activities of daily living. Mean oxford score was 39 (36–48). Range of movement post-operatively had a mean active forward extension 97° (70–150°) and abduction 101° (80–170°). 43% of patients were pain-free, whilst the remainder only required the use of occasional analgesia. One patient developed heterotrophic ossification post operatively and underwent surgical excision. One patient sustained a peri-prosthetic avulsion fracture at 18months treated non-operatively. Patients who underwent RSA for dislocation fared better than for those with proximal humeral fractures. The mean active forward extension was 107.5° (90–150°) and abduction 112.5° (90–170°) in the dislocation group (N=5) compared with those who had a fracture (N= 11) in which the forward extension was 91.4° (70–120°) and abduction 95° (80–120°). Conclusion. Reverse TSA should be considered in patients with complex proximal humeral fractures or delayed presentation with irreducible dislocation. Early results demonstrate good outcomes in terms of patient satisfaction, pain relief and preservation of function. These early result are encouraging however a further study with longer follow-up is required to confirm sustained benefit

Open fractures of the long bones of the limbs are associated with an increased risk of osteomyelitis and few studies investigate this complication in circular frames. We reviewed the incidence of and contributory factors toward infection-related outcomes in Grade 3 open fractures, managed with a circular frame, at a single centre. We performed a retrospective study of consecutive adult patients presenting with a Grade 3 open fracture, who required a circular frame for definitive skeletal fixation from 2005 to 2014. Patient case notes, microbiology results and radiological studies were reviewed for demographic details and surgical management. Infection-related outcomes were classified as ‘possible’ and ‘definitive’, based on clinical findings, microbiology and imaging features at follow-up at 6 and 12 months. 74 patients were identified with an average age of 43 years. There were 70 unilateral and 4 bilateral limb injuries. Most treated limbs had a tibial fracture (97%). There were 24 Gustillo-Anderson grade 3A, 37 grade 3B, 4 grade 3C and 9 not sub-classified. 33% of patients were debrided on the day of injury. Average time to circular frame installation was 14 days. 27 Ilizarov, 44 Taylor spatial and 3 other circular frames were used. A variety of plastic surgery reconstruction was used to provide wound coverage: skin grafts, local and free flaps. Circular frames were in place for 259 days on average. 10 patients (1 bilateral limb fracture) still have their frames in-situ. Additional bone grafting to the fracture site was carried out in 13 patients and 15 limbs (1 patient had 2 episodes of bone grafting to the same limb). 8 limbs in 8 patients were excluded from infection-related outcome analysis: 4 patients lost to follow-up, 2 patients who went on to below knee amputation and 2 patients had <6 months’ follow-up. 13 patients (14 limbs) had only 6 months’ follow-up and 53 patients (56 limbs) had 12 months’ follow-up. There were 5 patients (5 limbs) with ‘possible’ infection (7%): 1 screw infection and 4 soft tissue infections. 1 patient (1 limb) had a tissue-confirmed ‘definitive’ infected non-union (1.4%). Patients managed with circular frames typically have complex fracture configurations less amenable to other methods of definitive fixation. Our patient cohort has a limb salvage rate (97%) and a soft tissue infection rate (‘possible’ infection) comparable to other reported series. We report a low rate of osteomyelitis (‘definitive’ infection) in consecutive patients managed using our protocol

We would like to present this case series of 10 adolescent patients with displaced, closed diaphyseal tibial fractures managed using the Taylor Spatial Frame. Management options for these injuries include non-operative treatment, antegrade nailing, flexible nailing systems, plating and external circular fixation. External circular fixation allows anatomical reduction avoiding potential complications such as growth arrest associated with antegrade nailing and retained metal work with plating. Flexible nailing system and cast immobilisation are unreliable for precise anatomical reduction. With limited evidence as to the extent of post-traumatic deformity that is acceptable, combined with the limited remodeling potential that this patient group possess, the precision of percutaneous fixation with the Taylor Spatial Frame system has clear advantages. This is a retrospective analysis of 10 adolescent patients with a mean age of 14.5 years (range 13 to 16 years). Data collected includes fracture configuration, deformity both pre and post operatively compared to post frame removal, length of time in frame and complications. The data was gathered using the patient case notes and the Picture Archiving and Communications System. The mean time in frame was 15.5 weeks (range 11 to 22 weeks). One non-union in a cigarette smoker was successfully managed with a second Taylor Spatial Frame episode. Our conclusion was that with careful patient selection the Taylor Spatial Frame allows successful treatment of closed tibial fractures in adolescents, avoiding complications such as growth arrest and post-traumatic deformity as well as avoiding retained metalwork

Introduction. Fractures of the distal radius are one of the most common extremity fractures encountered in A&E departments and general adult fracture clinics. Over the last 10 years the rate of operation for distal radial fractures has been steadily increasing. Staff within our unit felt that formal teaching, particularly of new medical staff, with regards to fracture reduction and appropriate cast application could result in a reduction in operation rates. Methods. Retrospective data was extracted from FORD (Fracture Outcome and Research Database). Data included: the number of fractures in a 6 month period, number of fractures undergoing ORIF in that period, fracture configuration, patient demographics, and mechanism of injury. All patients undergoing ORIF had their radiographs assessed by 2 separate reviewers. Information regarding adequate fracture reduction, adequate cast application (using Gap Index calculation), and appropriate plaster cast moulding was recorded. Formal teaching was then given to the next group of medical staff rotating through the unit, and the same data was collected prospectively for that 6 month period. Exclusion criteria included bilateral injuries, and polytrauma patients. Results. A total of 1712 distal radial fractures were treated in our unit over the 12 month period, with 71 undergoing ORIF in the first 6 months and 37 in the second 6 months. Our study found that formal teaching and education of medical staff significantly reduced the operation rate for distal radial fractures in our unit. This effect was most significant for extra-articular, dorsally angulated fractures of the distal radius. Conclusion. In today's busy hospital environment it is sometimes all too easy to overlook the training of junior medical staff, our study proves that just 1 hour of basic training at the beginning of an attachment can have significant benefits to both the unit and, more importantly, the patients

The Fixion expandable nailing system provides an intramedullary fracture fixation solution without the need for locking screws. Proponents of this system have demonstrated shorter surgery times with rapid fracture healing, but several centres have reported suboptimal results with loss of fixation. This is the largest comparative series to be reported to date. We compared outcomes between 50 consecutive diaphyseal tibial fractures treated with a Fixion device at our institution to an age, sex and fracture configuration matched series of 57 fractures at a neighbouring hospital treated with a conventional interlocked intramedullary nail. Minimum follow up time was 2 years. Operating time was significantly reduced in the Fixion group (mean 61 minutes, range 20–99) compared to the interlocked group (88 minutes, 52–93), p< 0.00001. The union rate was no different between the Fixion group (93.9%) and the interlocked group (96.5%), p=0.527. Time to clinical and radiological union was significantly faster in the Fixion group (median 85 days, range 42–243) compared to the interlocked group (119, 70–362), p< 0.0001. The overall reoperation rate was lower in the Fixion series (24.5% vs 38.6%, p=0.121), although the majority of reoperations in the interlocked group were more minor, for screw removal. 3 Fixion nails were revised for fixation failure and 2 manipulations were required for rotational deformities after falls; all of these patients were non-compliant with post-operative instructions. There were no fixation failures in the interlocked group. 3 fractures were noted to propagate during inflation of Fixion nails. The Fixion nail is faster to implant and allows more physiological loading of the fracture, with a faster union time. However, these advantages are offset by a reduction in construct stability. Our results have demonstrated a learning curve with a reduction in complications as our indications were narrowed, avoiding osteoporotic, multifragmentary, unstable fractures and non-compliant patients

The aims of this study were (1) to assess whether rotational stability testing in Gartland III supracondylar fractures can be used intra-operatively in order to assess fracture stability following fixation with lateral-entry wires and (2) to quantify the incidence of rotational instability following lateral-entry wire fixation in Gartland type III supracondylar humeral fractures in children. Twenty-one consecutive patients admitted with Grade III supracondylar fractures at the Children's Hospital at Westmead were surgically treated according to a predetermined protocol. Following closed fracture reduction, 2 lateral-entry wires were inserted under radiographic control. Stability was then assessed by comparing lateral x-ray images in internal and external rotation. If the fracture was found to be rotationally unstable by the operating surgeon, a third lateral-entry wire was inserted and images repeated. A medial wire was used only if instability was demonstrated after the insertion of three lateral wires. Rotational stability was achieved with two lateral-entry wires in 6 cases, three lateral-entry wires in 10 cases and with an additional medial wire in 5 cases. Our results were compared to a control group of 24 patients treated at our hospital prior to introduction of this protocol. No patients returned to theatre following introduction of our protocol as opposed to 6 patients in the control group. On analysis of radiographs, the protocol resulted in significantly less fracture position loss as evidenced by change in Baumann's angle (p<0.05) and lateral rotational percentage (p<0.05). We conclude that the introduction of rotational stability testing allows intra-operative assessment of fracture fixation. Supracondylar fractures that are rotationally stable intra-operatively following wire fixation are unlikely to displace post-operatively. Only a small proportion (26%) of these fractures were rotationally stable with 2 lateral-entry wires. This may be a reflection of either the fracture configuration or inability to adequately engage the medial column

Introduction. Excessive soft tissue swelling will delay surgery for a proportion of patients admitted with ankle fractures. Surgical and anesthetic teams may waste time assessing patients destined to be cancelled due to swelling. The aim of this investigation was to determine factors associated with cancellation. Methods. Case notes of 87 patients (46 male, 41 female), mean age 43 years (range, 13 to 80) who underwent ankle fracture fixation were retrospectively analysed. 31 of 87 ankles (36%) were unsuitable for day after admission surgery due to swelling. Factors investigated included age, gender, mechanism of injury, fracture configuration and necessity for reduction on arrival in the emergency department due to dislocation; each factor was independently analysed for significance using Fisher's exact test. Results. Ankle fractures associated with a higher energy injury such as sports, falls from height and road traffic accidents were significantly more likely than simple slips to be cancelled due to excess swelling the following morning (p = 0.053). Tri- or bi-malleolar ankle injuries and fracture dislocations requiring manipulation in the emergency department were also significant risk factors for cancellation (p = 0.004 and p = 0.002 respectively). Patients presenting with at least two of these factors demonstrated a 71% probability of cancellation the following day (17 of 87 patients). Presence of three risk factors increased the probability of cancellation to 100% (3 of 87 patients). Conclusion. Cancellation on the day of surgery wastes time and causes patient distress. During busy on-call periods patients with all three risk criteria will almost certainly be too swollen for next day surgery. With the proviso that these fractures are immobilised in an acceptable position, patients could be rested with elevation and rebooked for surgery as opposed to being assessed and subsequently cancelled due to soft tissue swelling the day after injury

Purpose. Knowing the morphology of any fracture, including scaphoid fractures, is important in order to determine the fracture stability and the appropriate fixation technique. Scaphoid fractures are classified according to their radiographic appearance, and simple transverse waist fractures are considered the most common. There is no description in the literature of the 3-dimensional morphology of scaphoid fractures. Our hypothesis was that most scaphoid fractures are not perpendicular to its long axis, i.e. they are not simple transverse fractures. Methods. A 3-dimensional analysis was performed of CT scans of acute scaphoid fractures, conducted at two medical centres during a period of 6 years. A total of 124 scans were analysed (Amira Dev 5.3, Visage Imaging Inc). Thirty of the fractures were displaced and virtually reduced. Anatomical landmarks were marked on the distal radius articular surface in order to orient the scaphoid in the wrist. Shape analysis of the scaphoids and a calculation of the best fitted planes to the fractures were carried out implementing principal component analysis. The angles between the scaphoid's first principal axis to the fracture plane, articular plane and to the palmar-dorsal direction were measured. The fractures were analysed both for location (proximal, waist and distal) and for displacement. Results. There were 86 fractures of the waist (76 percent), 13 of the distal third and 25 of the proximal third. The average angle between the first principal axis of the scaphoid and the fracture plane was 52.6 degrees (SD 17) for all fractures, 55.6 degrees (SD 17.2) for the waist fractures, both differing significantly from a right angle (p<0.001). The majority of fractures were found to be horizontal oblique. We found no difference between the angles of the waist fractures which were displaced and those that were not displaced. In contrast, a significant difference was found between the displaced and non-displaced fractures when evaluating the orientation of the scaphoid long axis in relation to the articular plane (139.8 degrees with reduction versus 148.2 without; p=0.036). Conclusions. Most waist fractures were found to be horizontal oblique in relation to the long axis of the scaphoid and not transverse. Although the fracture angle could not explain displacement of the fracture, we found that the orientation of the scaphoid's long axis in relation to the radial articular surface was correlated with fracture displacement. According to these findings, fixation of all fractures along the long axis of the scaphoid should not be the optimal mode of fixation. Optimal fixation of acute scaphoid fractures may call for better analysis of each fracture configuration and the fixation should be guided by this analysis

INTRODUCTION. The number of patients undergoing total hip replacement surgery is rising and thus the number of periprosthetic fractures is set to increase. The risk factors for periprosthetic fractures include osteolysis, rheumatoid arthritis, osteoporosis and use of certain types of implants. Evidence from literature suggests that the mortality rate within one year is similar to that following treatment for hip fractures thus as surgeons it is important for us to understand the various management strategies of these fractures. MANAGEMENT. Acetabular periprosthetic fractures are uncommon and classified into Type I, in which the acetabular component is radiographically stable and Type II, in which the acetabular component is unstable. It is better to prevent than to treat these fractures. Femoral periprosthetic fractures have several classifications the most commonly used is the Vancouver classification (fig 1). Type-A fractures are proximal and can involve the greater or lesser trochanter. These are often related to osteolytic wear debris and therefore revision of the bearing surface with bone grafting is recommended. AG involves the greater trochanter and A. L. involves the lesser, and these can usually be stabilised by cerclage wires supplemented by screws or plates if required (fig 2). Management of type B fractures is more controversial and will be discussed in depth with reference to all recent papers at the meeting and data from the Swedish Joint Registry. In summary the management is shown in fig 3. In type-C fractures, one should ensure the fixation device bypasses the femoral stem by at least 2 diaphyseal diameters. Management is as shown in fig 4. DISCUSSION. The incidence of periprosthetic fractures is rising and effective management involves a multi-disciplinary approach, and begins with taking a careful history to identify co-morbidities, pre-fracture mobility, and pre-fracture symptoms of loosening or acetabular erosion. Use of NSAIDs and smoking status should be noted. Examination findings should focus on mental status, any signs of infection, neurovascular status and the integrity of the soft tissue envelope. Clear radiographs are required to effectively comment on bone quality and the identification of any pathological lesions. White cell count, CRP and ESR should help confirm the absence of infection and if any doubt exists, a pre-operative aspiration should be considered. Ideally surgery should be performed within 2 days of fracture by a revision arthroplasty surgeon, followed by monitoring on a high dependency unit. With regard to the formulation of an operative strategy, certainly there is no substitute for careful assessment of remaining bone stock, diameter of the canal, fracture configuration and patient-related factors. There is a paucity of data in the current literature relating to the management of acetabular fractures. Displaced femoral fractures are managed with cerclage fixation along with bone grafting of any osteolytic lesions and revision of the bearing surfaces. Regarding femoral periprosthetic fractures it would appear that one should err on the side of long stem revision arthroplasty +/− impaction allografting should any doubt exist around loosening of the implant since this reduces the one-year mortality rate and the risk of failure
