It is commonly believed that bilaterally dislocated hips associated with joint contractures should not be reduced, because movement is satisfactory, while open reduction leads to poor results. This report presents our experience with surgical management of bilateral dislocation of hips in children with AMC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods.<\/jats:title>\n                    <jats:p>During the period 1990 to 2000, we performed open reduction on 8 hips of 4 children with AMC. The mean age at surgery was 23 months (range, 5\u201348 months). Open reduction and capsular plication without any bony procedure were performed in 4 hips (2 patients). De-rotation and varus osteotomy of the femur was performed in 4 hips, and Salter osteotomy of the innominate bone in 2 hips. The average acetabular index was 44\u00b0, and the mean centre-edge angle was \u221241\u00b0 preoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>The average follow-up period was 4 years (range, 2\u20139 years). The average acetabular index and centre-edge angle were 19\u00b0 and 18\u00b0, respectively at the time of last follow-up. All children could walk without support. One child required re-opening for redislocation of hip joint. The clinical results were good in 6 hips and fair in 2 hips, according to Severin's and McKay's classifications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n                    <jats:p>Our experience shows that open reduction for bilateral dislocation of hips in children with AMC is a suitable option with generally good results.
