Aim: Assessing the efficacy of abduction orthoses in treating developmental hip dysplasia. Material and methods: This study is retrospective observational research that included kids who were diagnosed with hip dysplasia between the ages of 3 and 4 months and were given orthopedic splints for therapy beginning at 6 months of age. A total of 50 patients who fulfilled the criteria, were diagnosed with hip dysplasia, and received treatment were included in the study. The patients received treatment using two different orthopedic splints: the ring splint and the Milgram splint. The acetabular angle was measured radiographically at 6 and 12 months after the start of therapy using orthopedic splints. The initial radiographs were compared with later radiographs to assess the efficacy of the therapy in rectifying hip dysplasia.Results: Specifically, 25 patients (50%) were treated with the ring splint, while the remaining 25 patients (50%) received treatment with the Milgram splint. For patients treated with the ring splint, the mean acetabular angle decreased from 30.5 degrees (± 2.1) at baseline to 22.0 degrees (± 1.0) at 12 months. Similarly, patients treated with the Milgram splint showed a reduction in the mean acetabular angle from 31.0 degrees (± 1.8) at baseline to 22.5 degrees (± 1.2) at 12 months. These results indicate significant improvement in hip dysplasia as measured by acetabular angle reduction over the course of treatment with both types of splints. The average reduction in acetabular angle, a key indicator of treatment effectiveness, was consistent between the two types of orthopedic splints. Both the ring splint and the Milgram splint demonstrated an average reduction of 8.5 degrees in the acetabular angle from baseline to 12 months of treatment. Conclusion: The research suggests that persons with DDH may successfully decrease acetabular angles and treat hip dysplasia by using either the aro or milgram splint. The acetabular angles were dramatically decreased by the use of splint therapy, and the majority of patients achieved optimal angles around five months after starting treatment. Importantly, there was no significant difference in the efficiency of the two splints.
