Tibiotalocalcaneal nail and primary closure for the management of open ankle fractures in the elderly patient; results from a major trauma centre.

INTRODUCTION: Open ankle fractures in elderly patients are challenging injuries to manage. The aim of this study was to assess the outcome of elderly patients with open ankle fractures treated with a tibiotalocalcaneal nail and primary wound closure. METHODS: We identified all open ankle fractures in patients over 65 referred to our major trauma centre managed with a tibiotalocalcaneal nail and primary wound closure over 10 years. We recorded patient demographics, comorbidities, injury mechanism, length of stay, operation, weightbearing status, re-operations, infections and mortality. RESULTS: We included 34 patients with an average age of 87 (73-99). We found 56 % of patients' mobility status declined post-operatively and 21 % of patients were discharged directly home. Four patients required further unplanned surgery including two deep infections requiring amputation. We had a 6 % three month mortality rate. CONCLUSION: Use of a tibiotalocalcaneal nail with primary wound closure offers a reasonable treatment option for open fractures of the ankle in the elderly patient.

Strain reduction screws for nonunions following fixation around the elbow - A case series and review of the literature.

Background: Nonunions following fracture fixation result in significant patient morbidity and financial burden. Traditional operative management around the elbow consists of removal of metalwork, debridement of the nonunion and re-fixation with compression, often with bone grafting. Recently, some authors in the lower limb literature have described a minimally invasive technique used for select nonunions where simply placing screws across the nonunion facilitates healing by reducing inter-fragmentary strain. To our knowledge, this has not been described around the elbow, where traditional more invasive techniques continue to be employed. Aims: The aim of this study was to describe the application of strain reduction screws for management of select nonunions around the elbow. Methods & Results: We describe 4 cases (two humeral shaft, one distal humerus and one proximal ulna) of established nonunion following previous internal fixation, where minimally invasive placement of strain reduction screws were used. In all cases, no existing metal work was removed, the nonunion site was not opened, and no bone grafting or biologic stimulation was used. Surgery was performed between 9 and 24 months after the original fixation. 2.7 mm or 3.5 standard cortical screws were placed across the nonunion without lagging. Three fractures went on to unite with no further intervention required. One fracture required revision fixation using traditional techniques. Failure of the technique in this case did not adversely affect the subsequent revision procedure and has allowed refinement of the indications. Conclusion: Strain reduction screws are safe, simple and effective technique to treat select nonunions around the elbow. This technique has potential to be a paradigm shift in the management of these highly complex cases and is the first description in the upper limb to our knowledge.

Does a dedicated hip fracture unit improve clinical outcomes? A five-year case series.

INTRODUCTION: The aim of the study was to establish whether a dedicated hip fracture unit, geographically separate from the local major trauma centre, could improve clinical outcomes for patients sustaining proximal femoral fragility fractures. MATERIALS AND METHODS: This study was a retrospective case series, using data collected from Brighton and Sussex University Hospitals NHS Trust's submissions to the National Hip Fracture Database between 1 April 2011 and 16 September 2016. The outcomes measured were mortality, length of hospital stay, time from admission to surgical intervention and return to premorbid residence. Patients were compared before and after reconfiguration of services into a separate dedicated hip fracture unit geographically distinct from the major trauma centre. RESULTS: A total of 2117 patients (2178 injuries) were managed before the existence of the hip fracture unit, while 660 patients (673 injuries) were treated within the hip fracture unit. During the five-year study period, the 30-day mortality rate (pre-hip fracture unit 5.47% vs hip fracture unit 3.13%, P = 0.014), variance in the length of hospital stay (P < 0.001), mean time to surgical intervention (P = 0.044) and return to premorbid residence were significantly improved. An immediate 12-month comparison demonstrated significantly improved variance in length of hospital stay (P = 0.020) and return to premorbid residence (P = 0.015). DISCUSSION: The reconfiguration of services significantly reduced variance in length of stay, enabling accurate resource planning in future. Multiple incremental improvements in service provision, in addition to the hip fracture unit, may explain the lower mortality observed. CONCLUSION: While further research is required, replication of the hip fracture unit service model may potentially afford significant clinical and financial gains.

Standardised virtual fracture clinic management of radiographically stable Weber B ankle fractures is safe, cost effective and reproducible.

BACKGROUND: Virtual clinics have been shown to be safe and cost-effective in many specialties, yet barriers exist to their implementation in orthopaedics. Ankle fractures are common and therefore represent a significant clinical workload. The aim of this study was to evaluate the management of radiographically stable Weber B ankle fractures using a standardised treatment protocol in a virtual fracture clinic setting, to assess clinical outcomes, any complications and its cost effectiveness. METHODS: All patients referred to the VFC with an actual or suspected stable Weber B ankle fracture between September 2013 and September 2015 were identified. The primary outcome measure was successful fracture union. Any complications were noted and a cost analysis comparing the VFC and traditional fracture clinic models was undertaken. RESULTS: 314 patients referred with a radiographically stable Weber B ankle fracture were identified. Follow up was complete for 98.4% (309/314) of patients. The union rate was 99.4% (307/309) in patients where follow up was completed. 3.5% (11/309) of patients were underwent acute surgical intervention. Of these patients, 6 were identified as having an unstable injury on weight bearing radiographs at 2 weeks and underwent ORIF, 4 were identified as having an unstable injury on EUA and underwent ORIF and 1 had an EUA with no fixation. 2 patients required ORIF for radiographically confirmed non-union. A cost saving analysis comparing the traditional fracture clinic model and VFC model revealed a saving of £237 per patient (32% reduction) with a VFC model. This represents an estimated saving of almost £40,000 per year for the management of this injury alone in our institution. CONCLUSION: Our study supports the use of a virtual fracture clinic model that is standardised, initiated in ED, and is both safe and cost-effective in the management of radiographically stable Weber B ankle fractures. LEVEL OF EVIDENCE: Level III-Retrospective Cohort Study.

'Modern' distal femoral locking plates allow safe, early weight-bearing with a high rate of union and low rate of failure: five-year experience from a United Kingdom major trauma centre.

AIMS: Fractures of the distal femur can be challenging to manage and are on the increase in the elderly osteoporotic population. Management with casting or bracing can unacceptably limit a patient's ability to bear weight, but historically, operative fixation has been associated with a high rate of re-operation. In this study, we describe the outcomes of fixation using modern implants within a strategy of early return to function. PATIENTS AND METHODS: All patients treated at our centre with lateral distal femoral locking plates (LDFLP) between 2009 and 2014 were identified. Fracture classification and operative information including weight-bearing status, rates of union, re-operation, failure of implants and mortality rate, were recorded. RESULTS: A total of 127 fractures were identified in 122 patients. The mean age was 72.8 years (16 to 101) and 92 of the patients (75%) were female. A consultant performed the operation in 85 of the cases, (67%) with the remainder performed under direct consultant supervision. In total 107 patients (84%) were allowed to bear full weight immediately. The rate of clinical and radiological union was 81/85 (95%) and only four fractures of 127 (3%) fractures required re-operation for failure of surgery. The 30-day, three- and 12-month mortality rates were 6 (5%), 17 (15%) and 25 (22%), respectively. CONCLUSION: Our study suggests an exponential increase in the incidence of a fracture of the distal femur with age, analogous to the population suffering from a proximal femoral fracture. Allowing immediate unrestricted weight-bearing after LDFLP fixation in these elderly patients was not associated with failure of fixation. There was a high rate of union and low rate of re-operation.
