Salvage of a hip following pathological fracture through a large aneurysmal bone cyst: a case report.

A young lady aged 20 presented to us in 2004 with a pathological fracture of the left femoral neck through a large aneurysmal bone cyst. Instead of total hip arthroplasty, we performed one-stage reconstruction surgery combining internal fixation and free vascularized fibular grafting. At 4 years the structure and function of the hip had been preserved.
