Abstract:
Fifty-eight primary total hip arthroplasties with hyhrid cemented femoral component using contemporary cementing technique and cementless acctahular cup were followed for a minimum 3 year(ranged, 36 to 67 months, mean 4.1 years). Thc average age of the patients at the time of the operation was 54 years(ranged, 22 to 73 years). The preoperative common diagnosis were avascular necrosis of femoral head in 38 hips and miscellaneou. in 20 hips. The mean Harris hip score was 61 in preoperative and 91 in postoperative at last Follow-up. 5-1 hips(92%) were rated excellent and good clinically. One hip was revised for aseptic loosening of the femoral stem at 52 months follow-up. Radiographically no acetahular component was loose. Three femoral stems were definitely loose, one stem was classfied as prohahle loosenine and another one was ratde as possible loosening. There was no progressive radiolucent dermaation ol' cement-hone interf'ace in stable fermoral steni. Non progressive cement-bone radiolucency was lound seven hips in zone 1, two hips in zone 6, one hip in zone 2 and one hip in zone 7 at last follow-up. There were two postoperalive dislocations. Other complications included superficial infection(two hips) and sciatic nervc palsy(one hip). Our experience showed that the hyhrid hip replaccment with improved cementing technique provided satisfactory results at minimum 3 year follow-up study and emphasized the importantance of careful cementing techniques in survival ot cemented I'cmoral stem.
