The aim of this study was to review our experiences with tibial lengthening over an intramedullary nail in comparison to the conventional Ilizarov method.
We performed a retrospective comparison of tibial lengthening using the conventional Ilizarov method (group A: 23 limbs in 13 patients) versus over a nail (group B: 51 limbs in 26 patients). The percentage increase in tibial length, lengthening index, external fixation index, consolidation index and complications were assessed.
The mean gain in tibial length was 7.4 cm, which represents a mean increase of 26.0%. There was no difference in lengthening index or consolidation index; however, the patients in group A wore the external fixator longer than those in group B (281.5 versus 129.0 days), which represents a larger external fixation index (40.0 versus 17.4 day/cm). Group A had a higher complication rate (1.0 versus 0.47 per tibia) than group B.
Tibial lengthening over an intramedullary nail confers advantages over the conventional Ilizarov method, including shorter time needed for external fixation and lower complication rates.
本研究旨在回顾我们使用髓内钉进行胫骨延长的经验，并与传统伊里扎洛夫（Ilizarov）方法进行比较。
我们对使用传统伊里扎洛夫（Ilizarov）方法（A 组：13 名患者的 23 条肢体）和髓内钉（B 组：26 名患者的 51 条肢体）进行胫骨延长的病例进行回顾性比较。评估胫骨长度增加百分比、延长指数、外固定器指数、骨痂形成指数和并发症。
胫骨长度平均增加 7.4cm，代表平均增加 26.0%。延长指数和骨痂形成指数无差异；然而，A 组患者佩戴外固定器的时间长于 B 组（281.5 天比 129.0 天），代表外固定器指数较大（40.0 天比 17.4 天/cm）。A 组的并发症发生率（每条胫骨 1.0 比 0.47）高于 B 组。
髓内钉胫骨延长比传统伊里扎洛夫（Ilizarov）方法具有优势，包括外固定时间更短和并发症发生率更低。
