Abstract:
Seven patients aged six to 25 underwent progressive distraction lengthening of the forearm. Five had lengthening of the ulna and two of the radius. Four cases had multiple exostoses, two had post-traumatic distal epiphyseal arrests and one had dyschondrosteosis. Two methods were used: the Wagner technique of diaphyseal distraction and bone grafting, or diaphyseal corticotomy and callus distraction without bone grafting. The average lengthening achieved was 3 cm. Review after one to three year's follow-up showed satisfactory improvement in appearance and function in all cases, with minimal complications.
