摘要

Background

Total hip arthroplasty (THA) has emerged as a viable treatment for end-stage hip disease in patients with cerebral palsy (CP), yet long-term comparative data remain limited. This study evaluates postoperative outcomes in CP patients with hip dysplasia compared to a matched cohort with developmental hip dysplasia (DDH).

Methods

A retrospective comparative analysis of 72 patients (14 CP, 58 DDH) undergoing primary THA between November 2016 and December 2022 at a tertiary trauma center. All procedures used cementless Wagner SL stems and Zimmer Biomet acetabular components (G7, Trilogy, or TMT). Radiological parameters (stem alignment, acetabular inclination, anteversion) were measured using TraumaCad. Functional outcomes were assessed using modified Harris Hip Score (DDH) and CP-specific scales (CP group). Minimum follow-up was 12 months (mean 3 years).

Results

No significant differences were observed between groups in surgical time (138.5 vs. 139.4 min, p = 0.629), postoperative complications (21.3% vs. 12.2%, p = 0.633), or dislocation rates (7.14% vs. 5.17%, p = 0.72). The CP group required significantly more transfusions (50% vs. 13.7%, p = 0.01), but preoperative and postoperative hemoglobin levels were similar between groups (p > 0.05). Both groups demonstrated significant functional improvement and high satisfaction rates (92.3% vs. 96.55%, p = 0.472).

Conclusions

THA provides safe and effective pain relief and functional restoration in CP patients with hip dysplasia, with comparable outcomes to DDH patients despite greater surgical complexity. Tailored surgical approaches, including soft-tissue releases and selective femoral osteotomy, optimize outcomes in this population.
