Unstable Intertrochantric Hip Fractures.

Background: Intertrochanteric fractures continue to be one of the common orthopaedic injuries with heavy economic or/and social burden on the families and society. Internal fixation and early mobilization is the standard of care for these fractures. DHS is widely used, and is highly successful for the fixation of the stable types but performs less well with unstable fracture patterns and has relatively higher failure rates. Proper positioning of the lag screw in central and deep part of the femoral head is crucial. It remains unclear if the presumed theoretical benefits of the intramedullary implant and lateral stabilizing plate warrant the additional expenses.
