Extended proximal femoral osteotomy for severe acetabular protrusion following total hip arthroplasty. A technical note.

Exposing and removing the femoral and acetabular components after severe intrapelvic protrusion has occurred can be difficult and dangerous. An extended proximal femoral osteotomy carried distally to the level of the stem tip allows for atraumatic removal of the femoral stem without the need for preliminary dislocation. The exposure afforded by the osteotomy also facilitates acetabular component removal.
