目的 探讨Ilizarov肢体延长术在临床的应用和相关问题 ,重点讨论骨延长的成骨机制和软组织延长后的组织学变化及并发症。方法 对 1991～ 1998年所治疗的肢体延长进行总结分析。结果 36例中 ,男 2 1例 ,女 15例 ;年龄 4～ 17岁 ,平均 8岁。其中下肢不等长 30例 ,先天性桡骨头脱位 5例 ,双侧先天性肱骨内翻 1例。下肢延长 2 .5～ 9.5cm ,平均 5cm ,延长指数 2 8～40d/cm ,平均 32d/cm。尺骨延长 1.5～ 2 .5cm ,肱骨延长 9cm和 12cm。上肢延长指数 30～40d/cm ,平均 36d/cm。除 1例未完成延长外 ,其余病例均达到预期延长长度。结论 Ilizarov肢体延长术治疗肢体不等长、先天性桡骨头脱位具有良好的疗效。
Objective To investigate the clinical application of Ilizarov limb lengthening and related problems, and to focus on the osteogenesis mechanism of bone elongation and histological changes and complications after prolonged soft tissue. Methods From 1991 to 1998 the treatment of limb extension were analyzed. Results 36 cases, male 2 1 cases, 15 females; aged 4 to 17 years, mean 8 years. Among them, 30 cases had unequal length of lower extremities, 5 cases of congenital radial head dislocation and 1 case of bilateral congenital humeral varus. Lower limbs extended 2.5 ~ 9.5cm, an average of 5cm, elongation index 28 ~ 40d / cm, an average of 32d / cm. Ulnar extension 1.5 ~ 2 .5cm, humerus extension 9cm and 12cm. Upper extremity extension index 30 ~ 40d / cm, an average of 36d / cm. Except for 1 case of unfinished extension, the remaining cases reached the expected extension. Conclusion Ilizarov limb extension for the treatment of limbs unequal length, congenital radial head dislocation has a good effect.
