Management preferences of orthopedic surgeons in developmental dysplasia of the hip under 1 year of age in Türkiye: Results of a nationwide cross-sectional survey.

Objective: This study aimed to evaluate the diagnosis and treatment preferences of orthopedic surgeons in developmental dysplasia of the hip (DDH) cases under the age of 1 in Türkiye with a higher incidence of DDH, estimated to be around 5-15 per 1000 live births.

Methods: This was a nationwide cross-sectional survey. A link for the online survey, including 16 multiple-choice questions, was sent to the email group of the National Orthopedic Society.

Results: Among 233 filled-out surveys, 211 met the inclusion criteria. Half of the participants had experience of <10 years as orthopedic surgeons, managed <25% of pediatric patients in daily practice, and treated <25 DDH cases per year before walking age. Ninety-seven percent used more than one method, hip ultrasound the most common, for exact diagnosis of DDH under 6 months. Pavlik harness was the most commonly preferred brace, but the use of Tübingen orthosis increased among experienced surgeons. The uppermost age limit for bracing was higher in surgeons dealing with more pediatric patients and treating more DDH cases. Dislocated hips and hips requiring closed/open reduction were more commonly referred to other surgeons by less experienced surgeons in terms of years, number of pediatric patients, and treated DDH cases per year. The lowest age limit for intervention under general anesthesia was lower in surgeons treating >25 DDH cases per year. Over one-third used both anterior and medial approach open reduction, but a trend to anterior open reduction alone was more evident in surgeons treating >50 DDH cases per year. More experienced surgeons were more prone to check the intraoperative reduction with postoperative computed tomography or magnetic resonance imaging. Diagnosis and treatment ages of DDH cases did not significantly change during the coronavirus disease 2019 pandemic.

Conclusion: Management preferences of orthopedic surgeons in DDH before walking age primarily depend on the rate of pediatric patients in daily practice and the number of treated DDH cases per year.
