To describe the surgical technique and clinical outcomes of high-energy proximal femur fractures treated with a 95-degree angled blade plate.
Retrospective case series.
Single academic Level I trauma center.
Forty-five consecutive patients from March 2012 to April 2017 who sustained a high-energy, unstable proximal femur fracture including (OTA/AO 31-A1, 31-A2, 31-A3, 31-B3, 32-A1a, and 32-C3i).
Open reduction internal fixation with a 95-degree angled blade plate used in conjunction with an articulated tensioning device.
Main Outcome Measurements:
Nonunion, malunion, secondary operations, and postoperative infection.
Twenty six patients were available for follow-up. The mean age was 43.8 (range 22–86) years, and 81% (21/26) were men. The most common fracture pattern was OTA/AO 31-A3.3. Two fractures were open. The articulated tensioner was used in 100% of cases. Average clinical follow-up was 19.2 (range 7–40) months. Twenty-four of 26 patients (92%) achieved osseous union after the index procedure. One patient underwent nonunion repair, and 2 patients had the blade plate removed as it was symptomatic laterally. No other secondary procedures were performed, and no instances of implant failure were seen. No patients had evidence of a superficial or deep infection.
We found that high-energy proximal femur fractures treated with a 95-degree condylar blade plate and articulated tensioning device had a high rate of union with minimal postoperative complications. Although intramedullary nailing of these fractures remains a preferred treatment modality, the angled blade plate with articulated tensioning device is an excellent option to restore anatomical alignment and obtain bony union in certain highly comminuted fracture patterns.
