TOTAL HIP-REPLACEMENT IN DYSPLASTIC HIPS USING FEMORAL-HEAD SHELF AUTOGRAFTS

A consecutive series of 30 dysplastic hips were treated with total hip arthroplasty using femoral head autograft shelf reconstruction and we re reviewed, Cemented cups were used in 13 hips and uncemented cups we re used in 17 hips, The average followup was 8.1 years (range, 5.2-13. 3 years), In the cemented group, the average preoperative Harris Hip S core was 44.8 points (range, 22-82 points), and in the uncemented grou p, it was 45 points (range, 23-61 points), At the final review, the av erage clinical score was 71.5 points (range, 46-98 points) in the ceme nted group, and in the uncemented group it was 87.5 points (range, 63- 100 points), Of the 30 cases, only 3 had unsuccessful results, giving a success rate of 90%. In terms of the autograft, all united to host b one, Resorption, when seen in either cemented or uncemented cups, was minor and restricted to the lateral nonweightbearing part of the graft , The present study supports using shelf autografts to reconstruct dys plastic hips at the time of total hip arthroplasty, In this series, ce mented and uncemented cups performed equally well.
