Management of Vancouver B2 and B3 femoral periprosthetic fractures using a modular cementless stem without allografting

Abstract

Purpose: We reviewed our experience with the management of B2 and B3 femoral periprosthetic fractures using a distally fixed modular femoral stem in 55 patients. Methods: All periprosthetic fractures were managed immediately after injury without using allograft; 53 hips were available for a mean follow up of 67 months. Results: All fractures united, and the mean Harris hip score at the last follow up was 72. Subsidence was noted in two patients (4%) within six months postoperatively and required revision surgery. One patient developed peroneal nerve palsy. Two hips dislocated and were managed by closed reduction. Conclusion: In these severe cases of periprosthetic fracture, the technique reviewed here proved to be reliable. © Springer-Verlag 2011.
