The current standard is based on the Canadian hip disarticulation prosthesis, a design originally pioneered in the 1950s by McLaurin. This type of HP prosthesis features a prosthetic hip joint mounted anteriorly on the socket, and below the level of the anatomical hip joint.
Successful fitting of the hip disarticulation prosthesis hinges on the evaluation of balance, lower abdominal tissue condition, and pelvic lordosis. Balance is needed to successfully put on and ambulate with the limb with minimal assistive aids.
Hip disarticulation is an amputation through the hip joint capsule, removing the entire lower extremity, with closure of the remaining musculature over the exposed acetabulum. Hip joint disarticulation was the classic procedure for the treatment of distal femoral osteosarcomas.
Amputations at or just below the hip–described as hemipelvectomy, hip disarticulation, and transpelvic amputations–are most commonly caused by trauma, cancer, or severe infection.
Simply put, a hip disarticulation prosthesis is an artificial limb used by amputees who had an amputation near the hip joint. Thanks to innovations in design, you can expect to have freedom again due to the increased movement of the prosthesis.
HD and HP prostheses was developed by Colin McLaurin in 1954. It was referred to as the "Canadian" type of prosthesis and is characterized by a limb with a rigid or semi rigid socket attached to a mobile hip joint, a mobile knee joint, and ana.
The Canadian-style hip disarticulation prosthesis really showed the benefits of positioning the hip in front of the socket. This design places the body’s weight behind the center of the hip joint motion, so the hip doesn’t bend backward into extension.
