Prosthetic hip joint is used primarily in a hip disarticulation/hemipelvectomywhich involves the complete removal of lower extremity from the hip joint. Hemipelvectomy/hip disarticulation prosthesis can be quite complex. The loss of the hip, knee and ankle require specialized components to restore function and mobility. However, fabricating and fitting a prosthesis for these amputation levels remains one of the major challenges faced by orthopaedics technology.
There are two major types of hip joints: the single axis joints (forward and backward movement) and the polycentric joint. The hip joints work together with the prosthetic knee and foot to efficiently aid the user.
