Capsulorrhaphy versus capsulectomy in open reduction of the hip for developmental dysplasia.

Abstract

Capsulorrhaphy and capsulectomy were prospectively compared in open reduction of the hip for developmental dysplasia. There were 39 patients: 16 capsulorrhaphy and 23 capsulectomy. Follow-up averaged 22 months postsurgery. The surgical technique included innominate osteotomy, and femoral shortening and derotation. Avascular necrosis developed in one capsulorrhaphy patient. Postoperative redislocation occurred in three capsulorrhaphy and no capsulectomy patients. Three capsulorrhaphy and three capsulectomy patients had acetabular dysplasia. Neither capsulorrhaphy nor capsulectomy produced superior hip motion at last examination.
