FAILURE OF THE SPIRAL BLADE MODULE OF THE AO UNREAMED FEMORAL NAIL

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