Review of Proximal Nail Antirotation (PFNA) and PFNA-2 – Our Local Experience

The proximal femoral nail antirotation (PFNA) device was\udrecently introduced as an option for intramedullary\udmanagement of pertrochanteric hip fractures. We report here\udlocal results with this relatively new implant. Sixty-two\udpatients with pertrochanteric or subtrochanteric fractures\udunderwent intramedullary fixation with PFNA devices in our\udcentre during the 14 month period from September 2008 to\udOctober 2009. Data for this report were retrieved from\udclinical case records and operative notes. We recorded the\udage, gender, length of stay and operative time, preoperative\udambulatory status and days required to regain mobility.\udFractures were classified using the AO classification (A1, A2\udand A3). Complications were also identified.There were 15\udmale and 47 female patients and the mean age was 74.3\udyears. The mean surgical duration was 76.1min and the\udaverage length of hospitalisation was 14.5 days. Five cases\udwere noted to have femoral shaft fracture and no occurrences\udof screw cutout. We found that 83.9% of the patients were\udable to regain preoperative mobility status by 6 months\udfollowing surgery. We conclude that the PFNA is an\udeffective implant for stabilisation of proximal hip fractures\udand that the local complication rate is similar to reports from\udother centres
