Treatment of periprosthetic femoral fractures after total hip arthroplasty

Objective To analyze the cause and results of treatment of periprosthetic femoral fractures after total hip arthroplasty,and explore the best operative methods for these fractures.Methods A retrospective analysis of the clinical data of 9 patients with periprosthetic femoral fracture after total hip arthroplasty treated in our hospital was performed.Two patients were treated by nonoperative methods;three patients by uncemented stems with distal fixation and one cemented stem.Three patients by bone grafting and Ni-Ti embracting fixation.Results Non healing was found in one patient who received nonoperative method,one was cured with nonoperative methods.All of the seven patients treated by operative methods were cured.Conclusion Type A fractures with well fixed stems can be treated by nonoperative methods;type B2 fractures should be treated by uncemented stems with distal fixation,type Bl and type C fractures should be treated by bone grafting and Ni-Ti embracting fixation.
