Loosening, revision and function of the cemented hip arthroplasty
(1996)- Abstract
- The goal of total hip replacement(THR) with a prosthesis is to improve the quality of life in the patients with hip disease. Loosening of the prosthesis is the most common cause of deteriorating long-term results. Reaction to wear products and stess-shielding giving rise to resorption of bone are usually blamed for this deterioration. There was no correlation between migration of the prosthetic components and wear of the acetabular cup in 14 patients after 3 years. This opposes the opinion that early migration is caused by wear products. The relation between bone loss and loosening was studied in 11 cases operated on with a mega prosthesis. In 8 cases there was severe cortical atrophy, but only one femoral component was loose.... (More)

In 8 cases there was severe cortical atrophy, but only one femoral component was loose. Consequently, stress-shielding does not cause loosening. The failure rate after revision is high. Early migration after revision was found in 21/24 cemented stems, in 5/5 stems operated on with impacted bone allografts and cement and in 15/17 cemented acetabular components. (Less)
