Vitallium® Cup Arthroplasty: Case Report of a 57-Year Follow-Up

Abstract not available. Introduction provided instead.

During the first half of the 20th century, interpositional/mold-cup arthroplasty of the femoral head was a popular form of treatment for afflictions of the hip joint. However, the technique lost favor after the introduction of total hip arthroplasty (THA). Interestingly, the concept of hemiresurfacing of the femoral head has gained momentum recently as a response to the lower success rate of THA for young persons with osteonecrosis. Here we report the case of a 57-year follow-up on a Vitallium® cup arthroplasty performed to treat the resultant deformity of Legg-Calvé-Perthes disease. This case represents a unique opportunity to view the results of a procedure that was one of the progenitors of modern hemiresurfacing arthroplasty.
