The modified capsular arthroplasty for young patients with developmental dislocation of the hip

ABSTRACT The present study aimed to investigate the clinical results of modified Codivilla–Hey Groves–Colonna capsular arthroplasty in treatment young patients with developmental dislocation hip. We retrospectively evaluated 90 (92 hips) who underwent from June 2012 2021. Hips were using hip Harris score (mHHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) 12-item International Hip Outcome Tool (iHOT-12). Tönnis osteoarthritis grade Severin classification system used assess radiographic outcomes. average age was 15.7 years (range: 8–26 years). mean pre-operative mHHS, WOMAC iHOT-12 83.03, 14.05 52.79, respectively. followed for a 41.1 months 12.1–120.9 months). had mHHS 83.61 31.2–97), 16.41 0–51) an 64.81 12.9–98.2) at final follow-up.
