[Treatment of extra-articular malunited fractures of the distal radius using osteotomy with interposition of a graft].

Malunited fractures of the distal end of the radius are corrected by an osteotomy transversely oriented at the level of the angulation (15 cases reported). After correction of the deformation (length and angulation) compact iliac bone graft is inserted. 5 malunited fractures with a volar deformation were corrected by a palmar surgical approach and AO-T-plate fixation. 8 cases with a dorsal displacement were corrected by a dorso-lateral surgical approach and fixed with K-wires (7 cases) and without any internal fixation (1 case). 2 cases with dorsal displacement were corrected by a palmar approach and AO-plate fixation. Clinical and radiological results are good, except one case with secondary displacement and malunion which needed an ulnar head resection and the other, in which the radius was not enough lengthened, and needed the ulnar to be shortened.
