The treatment of subtrochanteric femoral fractures remains difficult despite the introduction of modern intramedullary nailing techniques. Accurate fracture reduction, correct siting of the proximal entry point and restoration of medial support remain essential for a successful outcome. We report a case of failure of the spiral blade module of the AO unreamed femoral nail, which may have been precipitated by incorrect siting of the entry point, resulting in poor implant positioning within the femoral head.
