Abstract
Developmental dysplasia of the hip (DDH) is one of the prevalent musculoskeletal conditions in young adults and is a leading cause of hip osteoarthrosis in this age group. The optimum age for surgical intervention when needed is not well established in the literature and the lack of management guidelines and standard practice of DDH leads to different practices worldwide. This study aims to investigate the current practice of paediatric orthopaedic surgeons in diagnosing and treating DDH worldwide and identify points of agreement and disagreement.
A cross-sectional study utilizing an online questionnaire was designed to examine the different points of view and current practice of paediatric orthopaedic surgeons worldwide regarding DDH diagnosis and treatment.
Ninety-one surgeons responded, with an overall response of 45.5%. The vast majority of respondents use ultrasonography in children less than 3 months of age and pelvic radiography in over 3 months to diagnose DDH. Pavlik harness is the most popular DDH treatment for children younger than 6 months. For older children, closed reduction with hip spica cast is the most preferable treatment. The maximum duration of first-line treatment has a broad range. The treatment of bilateral DDH varies widely among surgeons.
This study shows clearly that paediatric orthopaedic surgeons do not agree on the diagnosis and treatment protocol of DDH, hence different approaches to this common disease are practised. The lack of an international guideline should motivate paediatric orthopaedic surgeons to discuss and formulate a uniform and evidence-based protocol for the diagnosis and treatment of DDH.
