Artificial Hip Joint Materials

Hip replacement was once impossible because although joints could easily be produced in a laboratory the human body rejected the materials.

Artificial hip joint materials.

Artificial hip during hip replacement a surgeon removes the damaged sections of your hip joint and replaces them with parts usually constructed of metal ceramic and very hard plastic. What materials are used in a hip replacement. Metals have good fracture resistance and are stong enough to be used in making of hip joints. This artificial joint prosthesis helps reduce pain and improve function.

The hip joint is a ball and socket joint and removal of the hip joint requires the surgeon to remove the ball and reshape the socket. When a hip replacement surgery is performed a damaged worn out hip joint is replaced with an artificial implant. Because of its durability and performance metal on polyethylene has been the leading artificial hip component material chosen by surgeons since hip replacement surgeries were first been performed. The many different materials used in hip replacement devices hip replacement devices break into a few big categories.

Both the socket and the ball are made of stainless steel titanium chromium cobalt or some combination of these. In view of these properties metals ceramics and polymers are the most used materials in the making of implants for artificial hip joints. It is also the least expensive bearing. Sometimes the pins that held the artificial joint to other bones worked loose and required further surgery.

The artificial implant is then positioned in the bone. In most cases the femoral stem component is built from titanium titanium cobalt stainless steel cobalt chromium alloys or a titanium and cobalt mixed metal. All implants shed debris as they wear. The materials used in the artificial implant may vary but they often include metal plastic or ceramic.

These implanted parts come in many shapes and sizes and what is implanted in your body may depend on. A typical hip replacement implant recreates the ball and socket of the normal hip joint with an artificial ball and an artificial socket. Artificial replacement parts can be made of strong plastic metal or ceramic. The most popular artificial hip joint is a bearing couple composed of a cross linked polyethylene clpe acetabular cup cobalt chromium molybdenum co cr mo alloy and toughened zirconia or alumina ceramic femoral head.
