Abstract:Objective To investigate the clinical effect of acetabular osteotomy combined with femoral osteotomy in the treatment of childhood developmental hip dysplasia (DDH).Methods The design method of this study was a retrospective research. Fifty children with developmental hip dysplasia who met the admission conditions of this hospital were selected and divided into the control group (acetabular side osteotomy) and the observation group (acetabular side osteotomy), according to different surgical methods. The surgical indicators and postoperative recovery effects were compared between the two groups.Results There was no statistically significant difference in operation time and intraoperative blood loss between the two groups (P > 0.05). Postoperative CE Angle, forward Angle, acetabular finger, and Makay scores were compared between the two groups, and the differences were statistically significant (P < 0.05). The postoperative CE angle of the observation group was higher than that of the control group, and the anteversion angle and acetabular index were lower than those of the controlgroup, both with statistically significant (P < 0.05). The Makay score in the observation group was higher than that in the control group (P < 0.05).Conclusion The acetabular lateral osteotomy combined with femoral lateral osteotomy has obvious effects on the developmental hip dysplasia in children, with less trauma and less bleeding. It is technology worth promoting that can effectively shape the acetabular vault and improve the acetabular function in children.
