Abstract
According to Boyd and Griffin, unstable intertrochanteric fractures account for 2% of all peritrochanteric fractures.
The management of unstable intertrochanteric fractures remains a problem for orthopaedic surgeons. Nonoperative treatment is difficult to reduce the fracture, and internal fixation has a high nonunion and failure rate. The purpose of treatment is to buttress the proximal fragment due to its different biomechanical behaviour and to avoid sliding and medialization of the distal fragment. Because these fractures frequently have a comminuted pattern with an unstable posteromedial fragment and a higher risk of collapse, an intramedullary nail is recommended for ”internal buttressing” of the head-neck fragment. The purpose of this study is to compare the results of using an intramedullary with an extramedullary method to treat unstable trochanteric fractures.
