Total Hip Replacement

The hip is a ball and socket joint, meaning the socket in the pelvis provides a deep cup into which the ball, or head, of the thigh bone fits. In the normal hip, both the head of the thigh bone and the pelvis are covered with cartilage, which allows for free and painless motion of the hip. Destruction of the cartilage results in significant pain and decreased movement.

When conservative treatment fails, such as therapy, weight loss, medications, or pain management, total hip replacement surgery is an option. The diseased or damaged portions of the joint--the socket and the ball of the thigh bone--are replaced with artificial joints designed specially to restore movement.

Partial Joint Replacement 
A partial joint replacement is when only one of the joint components is replaced.
