[Treatment of radial club hand with double articulated external fixators]

Congenital absence of the radius is a rare malformation, characterized by radial deviation of the hand to more than 90 degrees. Early treatment with plaster cast use to be enough to correct radial deviation, making easier surgical correction on several years later. We report a case of a newborn with radial club hand absence of the thumb of the right hand, bilateral hydronephrosis and bilateral cryptorchidism. Was treated with a new procedure, permitting wrist centralization, coupled with osteotomy and callostasis of the ulnar diaphysis using external fixation. We obtained an important success with this serial lengthening of the ulna.
