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 fem
ur. 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 fixat
ion of soft tissues. We performed this procedure in 5 patients who had a go
od functional outcome.
