Femoral anteversion osteotomy for the treatment of hip dislocation in Down syndrome: long-term evolution.

We propose a femoral desrotational osteotomy to antevert the femoral head associated with plication of the anterior and superior capsule for treatment in the early stages of hip dislocation in Down syndrome. Eight patients (10 hips) with Down syndrome and hip dislocation were reviewed. Five children (seven hips) were operated. We used the proposed surgical technique in three patients (four hips). The average follow-up was 11 years (range, 5-16 years). No infections or complications were observed. In our short experience, this is the recommended procedure in the early stages of hip dislocation in Down syndrome.
