Autogenous femoral head bone grafts for acetabular deficiency in total-hip arthroplasty for developmental dysplasia of the hip: long-term effect on pelvic bone stock.

Twenty-eight primary total-hip arthroplasties in 23 patients performed with autogenous femoral head bone graft augmentation for developmental hip dysplasia were retrospectively reviewed at 8 to 15 years. Five sockets were revised for different reasons. At revisions, 3 grafts were healed, the other 2 had substantial resorption. Immediately postoperatively, the mean medial to lateral graft thickness at the level of the superior border of the socket was 33 mm. Radiographs a mean of 4.8 years after operation demonstrated this thickness decreased by a mean of 1 mm (range, 0-10 mm). At 11 years (range, 8-15 years), radiographs in unrevised hips showed no cases of substantial further graft resorption.
