Clinical and radiographic outcome of patients treated with double innominate osteotomy for congenital hip dysplasia.

In this study, 21 patients who had undergone double innominate osteotomy for congenital hip dysplasia (CDH) were studied to determine if significant improvements in clinical and radiographic indexes were present at follow-up. Quantitative data reflecting functional status, pain level, and range of motion were obtained and analyzed statistically, as were standardized measurements from preoperative and postoperative radiographs. Statistically significant improvements at follow-up were observed in pain level, functional status, acetabular index, center-edge angle, and relative lateral displacement. Significant correlations were found between the postoperative functional score and several clinical indexes, but none were found between radiographic indexes and the final functional score.
