Effectiveness of abduction orthoses in the management of developmental hip dysplasia: a comparative retrospective study





Developmental hip dysplasia, Orthopedic splints, Aro splint, Milgram splint, Acetabular angle


Background: Developmental dysplasia of the hip (DDH) is a disorder marked by abnormal hip alignment or structure, often calling for orthopedic treatment. The purpose of this research was to compare the Aro and Milgram splints, two types of orthopedic splints, for use in treating diabetic foot disease.

Methods: Between three and four months of age, 53 patients were identified with hip dysplasia in a retrospective observational analysis. Beginning at six months of age, patients received treatment with either the aro splint or the milgram splint. At six and twelve months after the start of therapy, radiographic measures of the acetabular angle were made. Statistical analysis was done to assess the efficacy of the two splints and compare treatment results.

Results: The aro and milgram splints both reduced acetabular angles, and there was no discernible difference between them in terms of reaching the ideal angle. Most patients needed to get therapy for around five months to achieve the ideal angle. With both splints, there were notable decreases in acetabular angles, even though some patients were unable to achieve this angle. Eighty-one percent of the patients were female, which is consistent with established DDH demographics.

Conclusions: These findings suggest that both splints can lower acetabular angles and treat hip dysplasia in DDH patients. Both the aro and milgram splints lower acetabular angles and reverse hip dysplasia in DDH patients. Using either splint may enhance hip stability and function. Both splints are effective DDH therapeutic alternatives, according to these results.
