Overview

Cohort study reveals anatomical correction following rotational acetabular osteotomy in adolescents and adults with severe hip dysplasia, indicating its utility for advanced subluxation.

Key Points

  • Evaluate the radiographic and clinical outcomes of rotational acetabular osteotomy in adolescents and adults presenting with severe hip dysplasia.
  • Analyzed 41 hips (39 patients) with preoperative center-edge angles of Wiberg of -15 degrees or less who underwent rotational circumacetabular osteotomy.
  • Classified cohorts into Severin Group IV (subluxation; n=21) and Severin Group V (secondary acetabulum; n=20), with follow-up ranging from 4 years to 16 years and 7 months (mean: 7 years, 9 months).
  • Assessed anatomical realignment through roentgenographic indices and clinical outcomes via the Gibson and Benson modified Severin classification.
  • Roentgenographic assessments confirmed that surgical rotation corrected the majority of severely dysplastic hips to nearly normal anatomy.
  • Postoperative evaluations supported the procedure's efficacy for severe dysplasia characterized by high-grade subluxation or secondary acetabulum formation.
