An Analysis of Failure of Dynamic Hip Screw with Plate in the Management of Intertrochanteric Fractures

Intertrochanteric femoral fractures are common among older age group and are associated with substantial morbidity and mortality .Open reduction and internal fixation using dynamic hip screw (DHS) device remains the gold standard in the management of these fractures, but the fixation failure rate remains high especially in unstable fractures. This study was conducted on failures of dynamic hip screw fixation in the management of interochanteric femoral fractures between 2009 to 2011.Pre and post operative radiographs were assessed for fracture reduction. Using Evan's classification and Singh's index fractures were categorized and assessed for osteoporosis. Fracture pattern, fracture reduction, implant placement and degree of osteoporosis have been analyzed and shown to affect the rate of implant failure.
