Evaluation and Treatment of Femoral Osteolysis Following Total Hip Arthroplasty
Between 1990 and 2010, the prevalence of primary and revision total hip arthroplasties increased substantially. Advances in surgical techniques in conjunction with technological advances in the materials used allowed for increased prosthetic longevity, resulting in younger patients being considered candidates for the procedure. Thus, the total number of total hip arthroplasties has risen markedly. In 2009, 284,000 primary total hip arthroplasties and 45,000 revision total hip arthroplasties were performed in the United States. Substantial increases are predicted for both these procedures in the coming years. The demand for primary total hip arthroplasty has been estimated to increase to 572,000 by 2030. Revision procedures have been projected to increase to 96,700 by 2030 1-4 .
