Ten patients aged 3 to 13 years (mean, 9 years and 7 months) underwent forearm lengthening by callotasis. The indications for lengthening were shortening and/or deformity of the forearm due to exostosis of the distal ulna in five cases, enchondroma of the distal ulna in one, growth disturbance after fracture of the distal radius in one, radial club hand in one, congenital amputation of the forearm in one and congenital 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. Review 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 arrest.
10名年龄在3至13岁（平均9岁7个月）的患者接受了骨痂延长术进行前臂延长。延长的指征包括：5例因尺骨远端骨疣导致前臂缩短和/或畸形，1例尺骨远端内生软骨瘤，1例桡骨远端骨折后生长障碍，1例桡侧多指畸形手，1例先天性前臂截肢，1例桡骨头先天性脱位。4例延长尺骨，1例延长桡骨，5例同时延长桡骨和尺骨。平均延长长度为30毫米。遇到的并发症包括：3例针道渗液，5例骨痂骨折，1例骨痂延迟愈合，1例无骨痂形成。随访1至7年（平均4年9个月）后复查显示，外观和功能有令人满意的改善，尤其是患有肿瘤性疾病或创伤性骨骺停滞的患者。
