| Background Up to one-third of successfully reduced developmental dysplasia of the hip are complicated by residual acetabular dysplasia (RAD). RAD is a predictor of early degenerative hip disease. The purpose of this study is to assess the radiological results of Dega acetabuloplasty in RAD. Patients and Methods A total of 30 hips in 26 patients (23 girls and three boys) with RAD after open reduction of developmental dysplasia of the hip underwent Dega acetabuloplasty with or without plate femur extraction. There were 22 unilateral and four bilateral DDH. Results Treatment results were evaluated radiologically using the acetabular index, central edge angle, Severin grading, and the development of the acetabular sourcil. All hips at the final follow-up showed well-remodeled acetabulum with normalization of all radiological parameters with the mean final follow-up acetabular index was 23.82º and the mean final follow-up CE angle was 35.48º. We have 25 hips Severin grade 1a and 5 hips grade 2a. Conclusions Dega osteotomy is an effective tool for treating RAD and preventing its expected degenerative hip changes. | ||
