目的 探讨一种应用Ilizarov外固定架治疗儿童尺骨骨干续连症的方法及其疗效。方法 2009-02至2015-10,采用Ilizarov外固定架分步延长法,对29例尺骨骨干续连症患儿进行了矫治。通过定期门诊复查及拍摄患肢X线片,评估术后患肢畸形及功能改善情况。结果 患儿术后平均随访38个月,尺骨平均延长3.2 cm;1例延长过程中出现骨不连,通过调整延长速度后逐渐愈合;1例拆除外架后发生尺骨骨折,石膏固定后自行愈合。术后患儿腕关节、肘关节及前臂功能均得到改善。 结论 应用Ilizarov外固定架分步延长法治疗儿童尺骨骨干续连症效果明显,但术中要注意熟练操作,避免副损伤的发生,延长过程中要注意控制延长速度,做好各项并发症的预防。
Abstract
Objective To explore the use of Ilizarov external fixation for the treatment of children with diaphyseal aclasis.Methods Twenty-nine children with diaphyseal aclasis were treated with Ilizarov extension method at our hospital between February 2009 and October 2015. The effect of surgical correction of malformation and functional improvement of the limb were assessed via regular clinical reexaminations and X-ray.Results The patients were followed up for 38 months on average and the ulna was elongated 3.2 cm on average. There was one case with nonunion that was healed after the speed of elongation was slowed down. Fracture occurred in one case after frame removal, but was healed after 3 weeks of casting. The functions of the wrist, elbow and forearm were all improved after surgery.Conclusions The treatment of diaphyseal aclasis caused by hereditary multiple exostoses using the Ilizarov frame and step-by-step elongation has proved effective. Surgeons should be careful in controlling the speed of elongation to prevent secondary injury and related complications.
