Abstract Background: Periprosthetic fractures are a well-documented, serious complication of joint arthroplasty, occurring in up to 11% of hip replacements. We examined periprosthetic femoral fractures over an 8 year period to determine the demographics, fracture pattern and management options and associated outcomes. Furthermore, we sought to determine which comorbidities resulted in increased risk of 12 month mortality after periprosthetic fractures about hip replacements Methods: A retrospective review of a prospective fracture database was conducted for the years 2007–2015. The Fracture Outcomes Research Database (FORD) was interrogated for patients aged >60 years, admitted with periprosthetic hip fracture. Radiographic and Electronic Clinical Record review was performed to classify fractures, record treatments, comorbidies and 12 month mortality. A multivariate analysis was performed to determine comorbidities that significantly increased the risk of 12 month mortality. Results: A total of 189 patients were identified. The majority were Vancouver B1 fractures (61.9%); the operations were primarily cable plating (75.1%), with a smaller number of revision arthroplasties (21.2%) and only three proximal femoral replacement (1.6%). Four patients (2.1%) died before surgery. Only 27.3% returned to their usual residence post-discharge. Overall 30-day mortality was 2.1%, and one-year mortality was 11.6%. Patients who died tended to be older. In the multivariate analysis, ASA grade III/IV and active neoplasia were significant contributors to 12 month mortality. Conclusion(s): Our 12 month mortality (11.6%) is at the lower end of existing reported literature, and serves as a benchmark for UK practice. In the multivariate analysis, only ASA grade III/IV and an active neoplastic process were significantly associated with increased risk of mortality. Whilst large, multicenter trials, utilizing standardized treatment techniques are required to fully assess risk factors for 12-month mortality, it appears that those at significant risk are elderly, frail individuals with an active malignancy.

Fractured neck of femurs is a very common presentation to hospital, especially in an elderly population and in almost all cases requires an operation, usually a cemented or uncemented hemiarthroplasty. Current evidence and multiple guidance issued in UK suggest the use of cemented hemiarthroplasty above uncemented prostheses. This retrospective case series performed in District General Hospital in Wales, UK. Notes and radiographs of 80 consecutive patients who had hemiarthroplasty for the fracture of neck of femur were examined by independent observer. All patients received modern prosthesis-collarless, polished tapered cemented stem or fully HA-coated uncemented stem-based on the choice of treating consultant. There were 47 uncemented prostheses and 33 cemented hemiarthroplasties used. We identified 12 significant complications in the uncemented group (26 %) as compared to three in the cemented group (6 %). The most significant difference was periprosthetic fracture rate, with five in the uncemented group (10.7 %) as compared to none in the cemented group. There were a total of six reoperations in four patients all of whom had initially undergone uncemented operations. In both groups, 24-h mortality rate was similar. Our study supports the use of modern cemented prosthesis as opposed to modern uncemented hemiarthroplasty. Post-operative complication rate after uncemented prosthesis is unacceptably high, especially periprosthetic fracture rate. [ABSTRACT FROM AUTHOR]
