Changes in diagnostics and treatment pathways for developmental dysplasia of the hip after the introduction of national guidelines: An updated questionnaire amongst paediatric orthopaedic surgeons in The Netherlands.

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.
