Artificial Hip Joint Manufacturing Process

The size of your femur and pelvis any deformities or abnormalities of your hip joint.

Artificial hip joint manufacturing process.

Misplacement allowed the edges to be contacted resulting in premature wear unfortunately high metal ion levels at the joint and in the blood were found. A cemented prosthesis attaches to the bone with surgical cement. The basic design of an artificial hip joint includes an alloy femoral stem with a metallic or ceramic femoral head moving in an ultra high molecular weight polyethylene uhmwpe acetabular cup as shown in figures 13 1 and 13 5. A typical hip replacement regardless of approach anterior or posterior involves resurfacing bone and fitting your body with the best components to make up a new hip joint.

Here s what is involved in a typical hip replacement procedure. The study of the hip joint is very costly therefore another calculation method. Hip joint is an important human joints system.

During a hip replacement both of these ball and socket parts of the hip joint are replaced with metal and plastic components. A hip replacement dislocation occurs when the artificial ball of the. Under normal joint rotation the implants edges would not be contacted.

First the hip is dislocated. These implanted parts come in many shapes and sizes and what is implanted in your body may depend on. Manufacturing of the artificial hip is very crucial as poor surface roughness of the femoral head ball joint of the hip can promote further abrasive wear of the acetabulum a cup shaped bone in.

Adding to the uncertainty is the fact that a growing number of artificial hip retailers have faced lawsuits over the production of defective implants in recent years. A typical hip replacement implant recreates the ball and socket of the normal hip joint with an artificial ball and an artificial socket. An uncemented prosthesis attaches to the bone with a porous surface onto which the bone grows to attach to the prosthesis.
