Femoral varus derotation osteotomy for the treatment of habitual subluxation and dislocation of the pediatric hip in trisomy 21: a 10-year experience.

Background: Habitual hip subluxation and dislocation are potentially disabling features of the trisomy 21 syndrome. We describe outcomes after a femoral varus derotation osteotomy to achieve and maintain hip stability and community ambulation.

Methods: All individuals with trisomy 21, who underwent hip surgery at our institution between 1998 and 2008, were searched using the hospital databases.
