Hybrid assembly of metal head and femoral stem from different manufacturers during isolated acetabular revision.
During revision of a failed acetabular component with well-fixed antiquated femoral stem, the same variant of metal head is usually not available in the inventory production. We gathered the stems retrieved from revision surgeries and tried to reassemble with the commercially available femoral heads. This study reports the results of suitable hybrid assembly of metal heads with the most common antiquated femoral stems from different manufacturers. Three hybrid combinations were determined and pull-off strengths of these hybrid combinations were performed through in vitro studies to evaluate the quality of the taper locks.
