Anatomy of the hip and suitable prostheses

Research output: Chapter in Book/Report/Conference proceedingChapter


The hip joint is the articulation between the coxal bone and the femur. The hip is a ball-and-socket joint realized by the acetabulum (the socket) and the head of the femur (the ball). As any ball-and-socket type joint, the hip has a wide range of motion, including flexion, extension, abduction, adduction, internal rotation and external rotation. The function of the hip is to withstand body weight during standing and walking; during single-leg stance the hip joint must carry a load three times greater the body weight. Total joint replacements have been developed in an effort to eliminate pain and improve function of damaged joints. Total hip replacement is indicated for patients 60 to 75 years of age, with severe and debilitating hip pain that does not recede with non-surgical treatment and significant functional impairment. Contraindications for total hip replacement are the presence of an acute infection in any region of the body and any medical pathology able to unacceptably increase the operative risks. Total hip arthroplasty includes a femoral component (the stem) and an acetabular component (the socket or the cup). The method of fixation of cup and stem to the bone distinguishes between cemented and cementless total hip arthroplasty. Different options are available for the bearing surfaces. A polyethylene liner coupled with a metallic (cobalt-chromium) head represents the most widely used system.
