We lengthened 9 tibial segments over a nail to reduce the time in the external fixator in 5 patients with constitutional shortness. The median lengthening was 7 (5.5-7.3) cm and the external Ilizarov frame was removed after median 99 (63-125) days. In spite of a short time in the external fixator, consolidation was slow, with a median lengthening index of 4.4 (2.4-6.1) months/cm. The procedure resulted in 3 fatigue fractures of the intramedullary nail or interlocking screws that needed revision and bone grafting. In 1 patient, a deep intramedullary infection occurred. After the experience of these major complications we have returned to the traditional callotasis lengthening method described by Ilizarov.
我们对5例体质性矮小患者的9根胫骨干骺端进行了髓内钉延长，以缩短外固定架固定时间。平均延长长度为7（5.5 - 7.3）厘米，平均99（63 - 125）天后拆除外部伊里扎洛夫框架。尽管外固定架固定时间较短，但骨愈合缓慢，平均延长指数为4.4（2.4 - 6.1）个月/厘米。该手术导致3例髓内钉或交锁螺钉疲劳骨折，需要进行翻修和植骨。1例患者发生深部骨髓感染。经历这些主要并发症后，我们已恢复采用伊里扎洛夫描述的传统骨痂延长方法。
