Objective: We presented Salter pelvic osteotomy performed developmental hip dysplasia patients results with preoperative and postoperative avascular necrosis(AVN) grade and evaluated the effect of preoperative AVN on operation results. Materials and Methods: We examined eightteen patients' twenty two hips retrospectively whom open reduction and Salter pelvic osteotomy performed between 2002 and 2008. Clinical and radiological evaluation and AVN grading were done. Preperative and postoperative AVN grades were determined and compared. Results: Twenty two hips (19 girls, 3 boys; mean age 32.8months) were evaluated retrospectively . Mean follow up period was 26.7 months. Clinical results were excellent according to McKay's criteria in 18 hips (81%), good in 4 (18 %) and there were no bad or moderate result. In radiologic evaluation according to Severin's grade, 18 hips (81%) were evaluated as very good or good. The mean acetabular index which was 39,3±5,8 degree preoperatively decreased to 22,7± 5,4 degree postoperatively. There were avascular necrosis in five hips (22 %) preoperatively and in 10 hips (45 %) postoperatively. An increase in avascular necrosis grade or development of new avascular necrosis was seen in 8 (%36) patients postoperatively. Conclusions: Postoperative short term AVN rates are high in late diagnosed developmental hip dysplasia patients whom pelvic osteotomy were performed. Preoperative avascular necrosis grade and grade I avascular necrosis cases should be taken into consideration for more significant and comparable postoperative evaluation.

    Acetabular retroversion following acetabular osteotomy in hips with dysplasia can negatively effect the outcome. Total retroversion, where the entire anterior rim is lateral to the posterior rim, is rare and can easily be missed on pelvic radiographs due to the lack of a crossover sign. We...
