Assessment of the hip-spine relationship in total hip arthroplasty for childhood hip disorders sequelae.

In this article, we comment on the article by Oommen et al. Oommen et al provided a comprehensive overview of the management of hip centre restoration in total hip arthroplasty (THA) for childhood hip disorder sequelae. Given the developmental disparity in this population, specific preoperative planning is an essential prerequisite for the success of THA procedures. In the review by Oommen et al, assessments of acetabular and femoral anatomic variations were fully described. However, spinal malalignment and stiffness are common in physical and radiological examinations and should be taken into careful consideration when planning surgical procedures. Poor outcomes of THA for patients with comorbid hip and spinopelvic pathologies have been widely reported, especially for hips with childhood disorder sequelae. Therefore, in this editorial, we would like to emphasize the need for a thorough hip-spine evaluation of patients with childhood hip disorder sequelae before THA.
