We compared the complications and outcome of tibial lengthening using the Ilizarov method with and without the use of a supplementary intramedullary nail. In a retrospective case-matched series assembled from 176 patients with tibial lengthening, we matched 52 patients (26 pairs, group A with nail and group B without) according to the following criteria in order of importance: 1) difference in amount of lengthening (± 2 cm); 2) percentage difference in lengthening (± 5%); 3) difference in patient's age (± seven years); 4) aetiology of the shortening, and 5) level of difficulty in obtaining the correction. The outcome was evaluated using the external fixator index, the healing index and an outcome score according to the criteria of Paley. It was found that some complications were specific to group A or B respectively, but others were common to both groups. The outcome was generally better in lengthenings with a nail, although there was a higher incidence of rectifiable equinus deformity in these patients.
我们比较了使用伊里扎洛夫方法进行胫骨延长时，使用与不使用辅助髓内钉的并发症及治疗结果。在一项对176例胫骨延长患者进行回顾性病例匹配的研究中，我们按照以下重要性顺序的标准，匹配了52例患者（26对，A组使用髓内钉，B组未使用）：1）延长量差异（±2厘米）；2）延长百分比差异（±5%）；3）患者年龄差异（±7岁）；4）短缩病因；5）获得矫正的难度水平。根据帕利标准，使用外固定指数、愈合指数和治疗结果评分对治疗结果进行评估。结果发现，有些并发症分别是A组或B组特有的，但也有一些是两组共有的。使用髓内钉进行延长时，总体治疗结果通常更好，不过这些患者中可矫正马蹄足畸形的发生率更高。
