弹性髓内钉治疗儿童浮膝损伤

目的:观察弹性髓内钉微创治疗儿童浮膝损伤的临床疗效。方法 :自2009年1月至2017年9月,11例儿童漂浮膝损伤采用一次性切开复位弹性髓内钉内固定或外固定器固定治疗,男7例,女4例;年龄5.0～11.0岁,平均8.3岁。术后按Karlstrom的标准评定治疗结果。结果:11例患者均获随访,时间8～48个月,平均28个月。骨折均一次愈合,未出现骨折不愈合、畸形愈合及膝关节功能严重障碍等并发症,2例出现患肢较对侧长1.2～1.5 cm,无短缩。根据Karlstrom评分标准,优8例,良1例,中2例。结论:弹性髓内钉微创治疗儿童浮膝损伤是一种安全有效的治疗方式,能够有效使骨折复位并促进骨愈合,利于早期功能康复。

Treatment of floating knee injury in children with elastic intramedullary nail

Objective: To observe the clinical effect of elastic intramedullary nail in minimally invasive treatment of floating knee injury in children. Methods: From January 2009 to September 2017,11 children with floating knee injury were treated with one-off open reduction and elastic intramedullary nail or external fixator fixation,including 7 males and 4 females,aged 5.0 to 11.0 years,with an average age of 8.3 years. The treatment results were evaluated according to karlstrom''s standard. Results: Eleven patients were followed up for 8 to 48 months,with an average of 28 months. All the fractures healed at one time,and there were no complications such as nonunion,malunion and serious dysfunction of knee joint. The length of the affected limb in 2 cases was 1.2 to 1.5 cm longer than that in the opposite side without shortening. According to Karlstrom scoring standard,8 cases were excellent,1 case was good and 2 cases were middle. Conclusion: Elastic intramedullary nail minimally invasive treatment of floating knee injury in children is a safe and effective treatment,which can effectively reduce the fracture and promote bone healing,which is conducive to early functional recovery.
