Designs, Principles of Total Hip Prostheses

Abstract

The hip joint is one of the largest and most important joints of the body. It is the most perfect example of a ball and socket joint which is the simplest way of providing movement in every plane whilst giving strength and stability.

In life, the cyclic loading forces acting on it in different planes are more than a million times per year and so, any disorder affecting the hip joint markedly affects the individual activities.

The idea of removing the diseased joint while preserving the normal and biomechanical functions of the joint initiated the surgery of replacement arthroplasty and the successful reconstruction of the disorganized joint by total joint replacement is perhaps this century's most innovative and significant development in orthopaedic surgery.

Now, total hip arthroplasty is one of the most frequently performed operations in orthopaedic.
