Madelung's deformity. An end-result study of surgical treatment.

A long-term follow-up (average, eight years) of surgical treatment of thirteen cases of Madelung's deformity in eight patients showed that the Darrach procedure was successful when there was mild deformity and that biplane osteotomy of the radius combined with the Darrach procedure was needed for severe deformity. Subluxation of the lunate bone ulnarward occurred after the Darrach procedure but was not clinically symptomatic.
