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.
Total Hip Replacement
This helpful pamphlet describes hip replacement surgery in easy-to-understand terms, including the potential complications. It is required reading for our hip patients prior to surgery and has a section on minimally invasive hip surgery techniques.
Surgical Approaches to the Hip
This document reviews the pros and cons of anterior and posterior approaches to the hip joint during hip replacement surgery and answers questions raised by patients about the anterior approach, as well as the two-incision technique.
