Biomechanics of the hip joint and the effects of fracture of the acetabulum.

Abstract

The biomechanical analysis of the normal and arthritic hip joint have been the subject of numerous publications in orthopaedics. Biomechanical investigations focusing on the effect of fractures of the acetabulum on the alteration of hip joint mechanics have been a recent development. This paper outlines currently available methodologies for simulating load across the hip, and as measuring articular contact and contact stresses. Results of investigations of posterior wall fractures and transverse fractures of the acetabulum are presented. Directions for future research in the area of mechanical investigations of acetabular fractures are discussed.
