Hip Disarticulation
An amputation level in which the entire lower limb is removed through disarticulation at the hip joint, leaving the pelvis intact.
Full Definition
Hip disarticulation is a high-level amputation in which the femur is separated at the acetabulum, removing the entire lower extremity while preserving the pelvic girdle. It is indicated in cases of severe trauma, malignancy, or advanced vascular disease affecting the thigh and proximal structures. Prosthetic fitting at this level is highly specialised, requiring a total-contact pelvic socket and hip joint mechanism. Editorial accuracy is critical when distinguishing hip disarticulation from hemipelvectomy, which involves partial pelvic resection and represents a still more proximal amputation level.
Usage
Usage note: Do not confuse with hemipelvectomy. The distinction affects both surgical coding and prosthetic reimbursement categories.
