Eight patients (average age, 10 years) had a unilateral forearm lengthening procedure using the technique developed by Ilizarov. The procedure was performed in 4 patients with radial agenesis, in 2 with multiple hereditary exostosis, in 1 with ulnar agenesis, and in 1 with multiple enchondromatosis. Patients underwent distraction osteogenesis through either a unifocal or bifocal corticotomy. Forearm length increased on average 6.0 cm (range, 3.6-8.1 cm) or 54% (range, 21% to 94%) with a lengthening index of 1.3 months per centimeter (range, 0.6-1.9 months per centimeter). The length of follow-up averaged 4.5 years and involved office examinations with task evaluation and a questionnaire addressing function and appearance. Limb length discrepancy at follow-up measured 3.7 cm (range, 0.0-8.0 cm). Lengthening of the forearm was found to improve upper extremity function; it allowed the patient to reach distant body parts and to perform select activities requiring near-equal arm length. Forearm lengthening also improved the appearance of the arm if adequate soft tissue was preserved. Full restoration of arm length was not a requirement for a successful outcome and patient satisfaction with the results of the procedure was high.
8例患者（平均年龄10岁）采用伊里扎洛夫技术进行了单侧前臂延长手术。该手术应用于4例桡骨发育不全患者、2例多发性遗传性骨软骨瘤患者、1例尺骨发育不全患者和1例多发性内生软骨瘤患者。患者通过单焦点或双焦点皮质切开术进行牵张成骨。前臂长度平均增加6.0厘米（范围3.6 - 8.1厘米）或54%（范围21%至94%），延长指数为每厘米1.3个月（范围0.6 - 1.9个月/厘米）。随访时间平均为4.5年，包括门诊检查、任务评估以及一份关于功能和外观的问卷。随访时肢体长度差异为3.7厘米（范围0.0 - 8.0厘米）。发现前臂延长可改善上肢功能；使患者能够触及身体远处部位，并进行一些需要双臂长度近乎相等的特定活动。如果保留了足够的软组织，前臂延长还能改善手臂外观。成功的结果并不要求完全恢复手臂长度，患者对手术结果的满意度较高。
