Ten patients aged 3 to 13 years (mean, 9 years and 7 months) underwent
forearm lengthening by callotasis, The indications for lengthening we
re shortening and/or deformity of the forearm due to exostosis of the
distal ulna in five cases, enchondroma of the distal ulna in one, grow
th disturbance after fracture of the distal radius in one, radial club
hand in one, congenital amputation of the forearm in one and congenit
al dislocation of the radial head in one, Four had lengthening of the
ulna, one of the radius and five of both the radius and the ulna. The
average lengthening achieved was 30 mm, Complications encountered were
pin track discharge in three cases, callus fracture in five, delayed
consolidation of the callus in one and no callus formation in one, Rev
iew after 1 to 7 years follow-up (with a mean of 4 years and 9 months)
showed satisfactory improvement in appearance and function especially
in patients who had tumorous conditions or traumatic epiphyseal arres
