Stump lengthening after hip disarticulation using a modular endoprosthesis in 5 patients

Abstract

To reduce the disability after hip disarticulation, we developed a special surgical procedure in patients having a proximal femoral tumor with a large tumor involving the sciatic nerve or neoplasms involving the tibia and femur. The hip was disarticulated, but we preserved a musculocutaneous flap. A modular endoprosthesis was then placed in the acetabulum or, in case of an extraarticular resection of the hip joint, it was placed in the iliac bone. A trevira tube was used for reconstruction of the joint capsule and fixation of soft tissues. We performed this procedure in 5 patients who had a good functional outcome.
