Early Experience With the Proximal Femoral Locking Plate

Abstract

The purpose of this study was to evaluate the failure rate of proximal femoral locking plates after an initial 2 years of use at a Level I trauma center. This retrospective chart review included 13 patients with intertrochanteric or peritrochanteric femoral fractures who underwent open reduction and internal fixation. Average patient age was 47 years (range, 23-80 years); average follow-up was 12.7 months (range, 2 weeks to 23 months). Three (23%) patients experienced catastrophic failure of the implant. The overall revision rate was 46% (6 of 13). One patient experienced avascular necrosis and required a planned total hip arthroplasty. In the appropriate setting, the proximal femoral locking plate can offer stable fixation for fractures involving the proximal femur; however, this series highlights the difficulties associated with treating these injuries, especially in patients with multiple injuries. Care must be taken to avoid varus malalignment and to address metabolic bone dysfunction.
