Hip Replacement

Hip replacement makes use of an artificial ball and socket to replace painful bone surfaces and restore smooth motion of the hip joint. The new socket fits into the pelvis tightly so that bone grows into the implant. A plastic liner locks into the socket as the bearing surface. Metal liners have been associated with early failures, so ceramic heads are currently favored over metallic ones in order to reduce the risk of corrosion developing at the taper joint.

The new ball is secured to a metal stem, which is fixed to the upper thigh bone. This component is either press-fit to allow bone growth fixation, or it is cemented into place. This determination is made based on the quality and shape of the bone, age of the patient, and other important factors.

Hip replacement is one of the most reliable orthopedic procedures available. Techniques have evolved in recent years to minimize patient pain, blood loss, and the length of hospital stays. Most patients are able to ambulate the day of surgery and regain independent function and activity quickly.
