Background And Aim:
The management of femoral periprosthetic fractures following hip replacement surgery is a complex and challenging situation. Whilst the early complications for both primary hip arthroplasty and proximal femoral fracture surgery have been widely documented, there is a paucity of published data regarding early outcomes following periprosthetic fracture surgery. Delay to surgery for native proximal femoral fractures has been clearly documented as a predictor towards adverse outcome. This study therefore aims to correlate the timing of operative intervention with the complication rate following periprosthetic fracture surgery. In addition, the study aims to identify further factors in the perioperative period that positively predict a poor postoperative outcome.
Methods:
Sixty patients who were operatively managed for a femoral implant periprosthetic fracture were identified and each case assessed retrospectively.
Results And Conclusion:
There was an overall complication rate of 45% including a 30-day mortality of 10%. An abbreviated mental test score of 8 out of 10 or less and a delay to surgery of >72h were found to be significant risk factors for adverse outcome. Both the patient cohort in this study and the predictors for poor postoperative outcome were comparable to those for native proximal femoral fractures.
