Proximal Femoral Nail Antirotation (PFNA) I one of the implants commonly used to stabilise subtrochanteric fractures or communited inter/pertrochanteric fractures. The aim of this project was to assess the outcome of PFNA in a busy District General Hospital. Between November 2009 to November 2012, 76 patients underwent PFNA. These patients were identified from the local hip fracture database, which is prospectively collected.

The mean age of the patients was 80.11 years (range of 26.83 to 98.53). 27 were male and 49 female. Right hip was involved in 36 cases and left hip in 40. 9 patients required revision surgery due to failure of the primary surgery. 2 patients died due to other causes. 5 out of the 9 patients who underwent revision surgery had their primary surgery performed by a trainee under consultant supervision and a consultant surgeon performed the other 4 cases. In our series failure rate was 11.8%. We conclude that although PFNA is an excellent device to fix subtrochanteric or communited intertrochanteric fractures of the proximal femur one needs to be cautious and follow the correct operative technique to avoid failures.

The PFNA is used routinely at the RUH for unstable peri-trochanteric and femoral fractures. Failure of operative treatment is associated with increased morbidity and financial burden. We analysed surgical and fracture factors, aiming to identify those associated with fixation failure.

Retrospective analysis of 76 consecutive patients treated with a PFNA between 2009–2012 was performed. Patient demographics were assessed, along with fracture classification, adequacy of reduction, tip apex distance (TAD) and grade of surgeon. Failure was defined as metal work failure, non-union or need for repeat procedure.

The mean age was 78.9 years (25.9–97.4). 21 were male and 49 female. There were 17 failures (24.3%) (7 required further surgery). 10 failures were per-trochanteric, 2 sub-trochanteric and 5 mid-shaft fractures. Complications included 4 broken and 6 backed-out distal locking screws, 2 blade cut-outs, 1 nail fracture and 4 non-unions. All per-trochanteric were adequately reduced with a TAD <25 mm. 11/17 had consultant supervision.

A high rate of backed-out distal locking screws was identified. We found no concerns with adequacy of reduction, TAD or consultant supervision.
