Total hip arthroplasty for sequelae of childhood hip disorders: Current review of management to achieve hip centre restoration

Core Tip

Core Tip: Total hip arthroplasty for childhood disorders in adulthood requires careful planning and awareness regarding the acetabular and femoral anatomic variations. Preoperative planning must include templating to understand acetabular and femoral sizing, offset, and neck length requirements, while modularity may be needed to address any meta-diaphyseal changes. Small acetabular and femoral components are commonly required in these hips to achieve good fixation. Preoperative assessment of the shortening pattern would help plan for a femoral shortening osteotomy, which may be necessary in patients with high-riding hips. Adequate exposure, extensive soft-tissue release, and restoration of the hip centre, leg length and offset are required to achieve favourable long-term outcomes.
