FEMORAL IMPACTION BONE GRAFTING IN REVISION HIP REPLACEMENT – MID-TERM REVIEW

This was an assessment of the clinical and radiological outcome of impaction allografting using morselised cancellous bone allograft in femoral component revision in total hip arthroplasty.27 consecutive femoral revisions operated on by a single surgeon (SJK) since 1995 were reviewed. Morselised bone allograft was used to reconstitute bone stock deficiency. All patients had cemented Exeter X-change technique Patient selection was primarily based on the amount of preoperative bone loss that was graded according to the Endo-Klinik classification. 10 hips were Endo-Klinik grade 2, 16 hips grade 3 and 1 hip grade 4. Both the components were revised in 18 hips.The duration of follow up was 12–56 months (average: 33 months) Clinical outcome was assessed using the Charnley modification of Merle d’Aubigne and Postel score. Radiographs were standardised & assessment was done on digitised images of the radiographs using the Image Tool program (Wilcox, Dove, McDavid and Greer, UTHSCSA, Texas, USA).Charnley’s scores ...
