We reviewed our clinical and radiographic results in the operative treatment of five unilateral and six bilateral hip dislocations in 11 patients with amyoplasia-type arthrogryposis. The mean age at surgery was 1.8 (range, 1.1–3.2) years. Femoral and/or pelvic osteotomies were combined with an open reduction. The mean follow-up period was 12.7 (range, 5.2–23.2) years. Nine patients were community walkers and two were household walkers. The range of motion and the St Clair hip score of the bilateral hips were not significantly different from those of the unilateral hips. Successful reduction increases the ambulation potential in both unilateral and bilateral hip dislocations.
