[Posttraumatic club-hand. Therapeutic problems (apropos of 5 cases)]

Progressive radial deviation after epiphyseal separation in children is a rare complication. It is related to an imbalance of residual growth potential of the lower ends of the radius and ulna together. The functional disability is generally moderate. 5 cases were observed by the authors, all of which were treated surgically. The mechanism of the deformity and the surgical techniques are described. These are lengthening of the radius, angulation osteotomy of the radius, shortening of the ulna or epiphysiodeses. In some cases, operative excision of a partial epiphyseal closure can be done provided that there has been a close follow up after the trauma and an early diagnosis.
