Comparison of femur intertrochanteric fracture fixation with hemiarthroplasty and proximal femoral nail systems

Abstract

BACKGROUND: The aim of this study was to compare the outcomes of intertrochanteric femur fractures treated with proximal femoral nail (PFN) and bipolar hemiarthroplasty (BPH) in elderly patients.

METHODS: A total of one hundred and forty-three patients with intertrochanteric femur fractures treated surgically between January 2008 and January 2012 were included into the study. Patient demographics, type of fracture according to Association for Osteosynthesis/Association for the Study of Internal Fixation (AO/ASIF) classification, and the American Society of Anesthesiologists (ASA) classification system scores; type of surgical procedure (BPH or PFN), operative details, complications and follow-up scores (Harris Hip Score [HHS]; Mean Mobility Score [MMS]) were recorded.

RESULTS: The preoperative characteristics of the patients in both PFN and BPH groups were similar. BPH had higher operation times, blood loss in operation and mortality rates (p < 0.005). Reoperation times were higher in PFN group (p < 0.005). There were no differences with regard to the HHS and the reduction in MMS at the last follow-up with a 30.4 (10.9) months follow-up (p > 0.05).

CONCLUSION: Although both PFN and BPH had satisfactory outcomes in surgically treated patients with intertrochanteric femur fractures, we recommend intertrochanteric femur fractures in the elderly tobe treated with PFN; which is an effective and appropriate treatment modality with less surgery related trauma and lower mortality rates.
