Clinical treatment of traumatic hip dislocation in children: a single-centre retrospective study.

This study aimed to analyse the treatment and outcomes of traumatic hip dislocation (THD) in children. Clinical data of children with THD were collected at our clinical centre from 1 June 2012 to 1 January 2023. Demographic data, injury mechanism, type of dislocation, combined injuries, reduction time, reduction method, and radiographs were analysed. The Merle d'Aubigné-Postel hip score was used to evaluate hip function and complications at the final follow-up. A total of 19 children with THD were enrolled, including 12 male and seven female patients, with an average age of 8.28 ± 0.99 years. Posterior dislocation was the main type of dislocation (89.47%). Fifteen patients (78.95%) had experienced high-energy injuries and traffic accidents were the main causes of injury (47.37%). Closed reduction was performed as soon as possible, and open reduction was performed if necessary. The hip scores of 18 patients (94.74%) were excellent. One patient had osteonecrosis of the femoral head, with a hip function score of 10 (moderate). High-energy injuries, such as traffic accidents, have gradually become the main cause of injury. The prognosis for THD in children is generally good.
