Pertrochanteric fractures treated with long proximal femur nail: a prospective study at a tertiary hospital

BACKGROUND: Pertrochanteric fractures are proximal femur fractures commonly seen in the elderly population and account for high mortality and morbidity. Various implants are available for the surgical fixation of such fractures. Cephalomedullary implants (proximal femur nail, PFN) is the preferred implant of in the treatment of these fractures. The aim of this study was to evaluate the functional outcome in patients treated for pertrochanteric fractures using cephalomedullary nails (long proximal femur nail), and to study the complications related with the use of long proximal femoral nails. METHODS: Prospective study conducted at a tertiary care center with a study population of 44 patients. Fractures categorized by Boyd and Griffin Classification. Selection of patients done using inclusion and exclusion criteria and functional outcome was noted using Harris hip score and parker mobility score. RESULTS: Good functional outcome seen in patients treated with long PFN. Majority of the study population had an excellent Harris Hip Score. Few complications encountered include malunion, z effect, superficial infection, and implant failure which were managed successfully. CONCLUSIONS: In comparison to extramedullary implants, cephalomedullary nails have a shorter lever arm and a shorter distance from the nail to the hip joint, which results in better outcomes (a shorter operating time, less intraoperative blood loss, and early mobilization with lower complication rates.
