EIGHT TO TEN-YEAR RESULTS OF THE AML FEMORAL STEM AND DURALOC CUPS



Abstract

This was a retrospective study of all AML uncemented femoral prostheses and Duraloc cups in a consecutive series of patients treated between 1990 and 1995. Patients were evaluated clinically using the Merle Score. Radiological parameters included osseo-integration, subsidence and wear. Failure was defined as removal of implants or revision.

The 8 to 10-year results show a 99% survival rate. One patient was revised for femoral stem loosening following trauma. One patient with rheumatoid disease required revision for acetabular cup loosening after a few days.

We conclude that the results of the uncemented AML femoral stem and Duraloc cup are excellent in the South African population.
