A typical hip replacement implant recreates the ball and socket of the normal hip joint with an artificial ball and an artificial socket.
Artificial hip joint materials.
This artificial joint prosthesis helps reduce pain and improve function.
The table shows below some of the mechanical properties of the most frequent used materials in this modern world.
Metal on metal mom these are what they sound like.
In view of these properties metals ceramics and polymers are the most used materials in the making of implants for artificial hip joints.
When a hip replacement surgery is performed a damaged worn out hip joint is replaced with an artificial implant.
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.
Sometimes the pins that held the artificial joint to other bones worked loose and required further surgery.
The many different materials used in hip replacement devices hip replacement devices break into a few big categories.
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 artificial implant is then positioned in the bone.
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.
Both the socket and the ball are made of stainless steel titanium chromium cobalt or some combination of these.
These implanted parts come in many shapes and sizes and what is implanted in your body may depend on.
Hip replacement was once impossible because although joints could easily be produced in a laboratory the human body rejected the 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.
All implants shed debris as they wear.
What materials are used in a hip replacement.
The materials used in the artificial implant may vary but they often include metal plastic or ceramic.
Artificial replacement parts can be made of strong plastic metal or ceramic.
Metals have good fracture resistance and are stong enough to be used in making of hip joints.
