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 introduc ed in which the acetabular component used was cementless and the femor al component was fixed with cement. This has been called the hybrid to tal hip replacement. The rationale for this approach is presented and intermediate term results (average, 6.6-year followup) showed that amo ng 65 consecutive standard hybrid total hip replacements in patients w ho 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 co mponents, 3 were removed in 2 patients. One patient had both component s removed because of recurrent dislocation and 1 patient had the aceta bular component revised because of failure of fixation of the polyethy lene liner. The clinical results of this approach were excellent in th e intermediate term and may have promise for the longterm.
