Safe Surgical Dislocation

Safe surgical dislocation of the hip

Earlier surgical techniques to dislocate the native hip carried the risk of causing avascular necrosis. Reinhold Ganz developed an approach to the hip that allowed dislocation of the hip and wide exposure of the femoral head and the acetabulum with a very low risk of causing avascular necrosis.

The approach is through a lateral incision in the lateral position, followed by posterior to anterior trochanteric flip osteotomy and anterior dislocation of the femoral head. It does not cut any important muscles, protects the blood vessels to the femoral head, and exposes the femoral head and neck, and the acetabulum for all types of surgical techniques. Though the incision is long, healing and pain relief are quick, and approach related complications are minor.
