Abstract

Abstract:

Objective

To report therapeutic effects of surgical treatment on six cases of femoral periprosthetic fracture after primary hip arthroplasty with Profemur^? Z stem.

Methods

Six cases (seven hips) who received primary hip arthroplasty for end stage of hip osteopathy or femoral neck fracture were collected during 2009 to 2017. All the cases used the Profemur^? Z stem and all of them had no metabolic bone diseases but suffered from postoperative femoral periprosthetic fractures after trauma, including five hips of long spiral, long oblique or comminuted fractures and two hips of short oblique fracture. Two hips were Vancouver B1 type and five hips were B2 type. Surgeries were performed according to Vancouver classification, open reduction and internal fixation(ORIF), or revision arthroplasty plus ORIF were conducted respectively.

Results

No postoperative complication happened, and fractures were all healed at three months postoperatively. Good hip function was obtained in all the cases; HSS score was (85.5±4.5) on average at the time of latest follow-up.

Conclusion

The femoral periprosthetic fractures following primary hip arthroplasty with Profemur^? Z stem can be effectively l treated by surgical treatment according to Vancouver classification.
