Hemipelvectomy & Hip Disarticulate
A hemipelvectomy amputation is the surgical removal of a portion of the pelvis (hip) and the entire lower extremity (leg).
A hip disarticulation procedure is the surgical removal of the femur (thigh bone) from the pelvic girdle (hip). The entire lower extremity (leg) is separated from the body without cutting through the bones.
Knee for Hemipelvectomy or Hip Disarticulation Prosthesis
The knee used in a hemipelvectomy or hip disarticulation prosthesis is often a mechanically stable knee of polycentric (more than one axis of rotation) design in which the flexion and extension can be controlled by either a pneumatic (air-filled) or hydraulic (fluid-filled) cylinder.
Prosthetic Hip Joint
Hip joints can be either mechanical or computerized. The prosthetic hip joint mimics the human hip joint’s natural and symmetric gait pattern. Its polycentric design allows for leg length reduction during swing phase, which reduces the amputee’s risk of falling and increases function.
Single Axis Foot
The single axis prosthetic foot has a movable ankle joint. This joint allows the patient to reach foot flat quickly, thus increasing stability. This foot is often prescribed for above knee amputees and patients who require greater stability (K1, K2).
The sitting prosthesis is a device fabricated for use by hemipelvectomy amputees. The sitting prosthesis is made from closed cell foam, custom shaped for each patient, and held in place with a neoprene (foam) belt. Use of this device provides greater stability and balance for sitting and can help prevent curvature of the spine over time.
