Hybrid total hip replacement: rationale and intermediate clinical results.
The decade of the 1980s was considered by many hip surgeons to be the decade of cement versus cementless. An alternate approach was introduced in which the acetabular component used was cementless and the femoral component was fixed with cement. This has been called the hybrid total hip replacement. The rationale for this approach is presented and intermediate term results (average, 6.6-year followup) showed that among 65 consecutive standard hybrid total hip replacements in patients who had an average age of 61 years (range, 23-83 years) at the time of surgery, no femoral component was revised for aseptic loosening and no acetabular component was revised for aseptic loosening. Of the 130 components, 3 were removed in 2 patients. One patient had both components removed because of recurrent dislocation and 1 patient had the acetabular component revised because of failure of fixation of the polyethylene liner. The clinical results of this approach were excellent in the intermediate term and may have promise for the long term.
