We have reviewed the results of amputation through the ankle in the management of 37 children with congenital leg-length discrepancy, followed up for a mean of 7.6 years after operation. In general good function was achieved and 18 patients considered their activities to be unrestricted. The main factor affecting the functional result was the underlying condition for which operation had been performed. Although heel pad migration, scar rotation and os calcis remnants were seen, these could be accommodated by the prosthesis. Syme's amputation is tolerated well in the younger child and, in patients with a predicted leg-length discrepancy of over 15 cm associated with an abnormal foot, we recommend the operation as a primary procedure between the ages of 18 months and two years.
我们回顾了37例先天性下肢长度不等患儿行踝关节离断术的结果，术后平均随访7.6年。总体而言，功能恢复良好，18例患者认为其活动不受限。影响功能结果的主要因素是手术所针对的潜在病情。虽然观察到足跟垫移位、瘢痕旋转和跟骨残留，但这些情况可通过假肢来适应。Syme截肢术在年幼儿童中耐受性良好，对于预计下肢长度不等超过15 cm且足部异常的患者，我们建议在18个月至2岁之间将该手术作为首选术式。
