Abstract

Objectives: To compare the radiographic outcomes of our patients who encountered medial wall disruption, with those who did not while undergoing Dega osteotomy. Methods: We retrospectively reviewed the records of 95 hips with developmental dysplasia of the hip who were treated with Dega pelvic osteotomy. Hips were divided into 2 groups according to medial wall disruption: group A included the hips with medial wall disruption, while group B included the hips without disruption. Preoperative, immediate postoperative, 12 weeks and last follow-up anteroposterior radiographs of the pelvis were reviewed for changes in the acetabular index (AI) between groups. Results: There were 22 hips in group A and 73 hips in the group B. Preoperative (34.6 versus [vs] 37.2, p =0.231), postoperative (17.9 vs 18.4, p =0.682), 12th week (18 vs 18, p =0.504) and last follow-up (13.3 vs 15.1, p =0.097). The acetabular index measurements were comparable between the groups. Corrections achieved during surgery, and during the follow-up period were also comparable between the two groups, indicating no loss of radiographic correction caused by medial wall disruption. Ninety one percent of the patients in group A and 90% of group B achieved good or excellent results according to the Severin classification ( p =0.944). Conclusion: Our study shows that disruption of the medial wall did not have a significant detrimental effect on radiographic correction when performing Dega osteotomy.
