Shape memory embracing fixator for Vancouver type B and type C periprosthetic femoral fractures.
The purpose of this study was to analyze clinical and radiographical results of a group of patients with periprosthetic femoral fractures treated with the shape memory embracing fixator. We retrospectively reviewed twelve patients in whom a total of twelve periprosthetic femoral fractures were treated with the shape memory embracing fixator between August 2004 and February 2013. The patients were 3 men and 9 women (mean age, 69.9 years; range 42-92 years). The average duration of follow-up was 39.3 months (range 4-103 months). In one case, bone grafting was used. Postoperative evaluation was based on radiographs and Harris hip scores. All fractures healed at on average 4.4 months (range: 3 to 6 months) after surgery. None of the patients developed nonunion or malunion during the follow up. And there was no implant failure and no infection during follow up. The average Harris hip score at the final follow-up examination was 84.8 points. Results show that the shape memory embracing fixator is a safe and effective means for Vancouver type B and type C periprosthetic femoral fractures following hip arthroplasty.
