Total Hip Replacement

Joint Replacements
Total joint replacement are permanent implants, there are many things should be applied when using joint replacements:
? The design of an implant for joint replacement should be based on the kinematics and dynamic load transfer characteristic of the joint.
? The material properties, shape, and methods used for fixation of the implant to the patient determines the load transfer characteristics. This is one of the most important elements that determines long-term survival of the implant.
? The articulating surfaces of the joint should function with minimum friction and produce the least amount of wear products. The implant should be securely fixed to the body as early as possible.
Total Hip Replacement
The normal hip joint consists of the head of the thigh bone or a ball called (femoral head) and socket which consists of a section of your pelvis called the (acetabulum). Both are constructed of bones, the surface of each covered by a smooth layer of tissue called "cartilage" separates the ball and the socket allows the ball to glide easily inside the socket. It cushions your hip joint. Muscle and ligaments hold your hip joint in place.
