Abstract
If we live long enough our hip joints will show wear and tear changes which will be diagnosed osteoarthritis. Joints which have been damaged by injury or disease, and those presenting a faulty articulation following Legg-Calvé-Perthes disease, slipped femoral epiphysis, or subluxation of the hip may develop osteoarthritis before the age of 40. For many of these patients a very satisfactory result can be obtained by an arthroplasty in which the deformed femoral head is replaced with a prosthesis made of VITALLIUM® or stainless steel.
