Superolateral bone grafting for acetabular deficiency in primary total hip replacement and revision.
Dysplastic acetabula were augmented during total hip replacement by superolateral autografts. In cases of primary arthroplasty these were taken from the excised femoral head and in revision surgery from the iliac crest. Two or (usually) three small grafts were used to facilitate revascularisation; they were fixed with lag screws to the roughened iliac bone above the acetabulum. We reviewed 84 hips (63 primary arthroplasties and 21 revisions) more than five years (mean 10.1) after operation. All but one of the grafts showed consolidation within three months and they had become structurally integrated with the iliac bone, as evidenced by the trabecular reorientation. Resorption, which has caused early socket failure when large bone grafts have been used, did not occur.
