Purpose: Diagnostics and treatment pathways for developmental dysplasia of the hip are highly variable in clinical practice. Recently, two national guidelines were developed in the Netherlands, providing a uniform protocol for the diagnosis and treatment of developmental dysplasia of the hip in children under the age of 1 year. The aim of this survey study was to assess whether diagnostic and treatment strategies have changed amongst paediatric orthopaedic surgeons in the Netherlands compared to a similar survey study in 2011, after the introduction of the guidelines. Methods: A web-based online questionnaire was developed and shared amongst the members of the Dutch Paediatric Orthopaedic Society. The questions concerned the diagnosis and treatment of developmental dysplasia of the hip, ranging from mildly dysplastic to dislocated hips, in children under the age of 1 year. We used a questionnaire similar to the previous study and evaluated the results. Results: Thirty-four participants completed the survey. Regarding diagnosis and follow-up, ultrasonography was generally applied for children younger than 6 months, while radiography was more frequently used for children aged 6–12 months. In 2011, radiography was more widely applied in all age groups. Initial treatment for dysplastic, stable hips was mostly active monitoring, while this was generally a rigid splint in 2011. For dislocated unstable hips, the first step in treatment was generally the Pavlik harness, as in 2011. Conclusion: The diagnostic and treatment pathways of developmental dysplasia of the hip in children under the age of 1 year seem to have partially changed amongst Dutch paediatric orthopaedic surgeons compared to 2011, after the publication of new guidelines.
