钛制弹性钉治疗儿童长骨骨折67例疗效分析

Titanic elastic nailing fixation for treatment of pediatric long bone fractures in children: a report of 67 cases

目的：探讨儿童长骨干骨折在闭合复位后使用弹性髓内钉内固定治疗的临床疗效。方法：对67例儿童四肢长骨骨折采用钛制弹性髓内钉治疗。结果：67例均获得随访3~18个月，无骨折再移位、骨折不愈合及延迟愈合。股骨干、胫腓骨愈合时间为6~8周，肱骨干、尺桡骨干愈合时间4~6周，术后平均6个月取出内固定，患肢功能和邻近关节活动均接近正常。有4例患儿出现钉尾带来的软组织激惹及滑囊形成，取出内固定后消失。结论：作为一种安全、有效、微创、愈合快、功能恢复良好的方法，钛制弹性髓内钉治疗儿童四肢长骨骨折是一种可优先考虑的内固定材料。

Objective：To evaluate the clinical efficacy of titanic elastic nailing fixation on long bone fractures in children after closed reduction. Methods：Sixty-seven children with long bone fractures were treated using titanic elastic nailing. Results：All the 67 cases were followed up from 3 to 18 months. No fracture redisplacement,nonunion or delayed union occurred. The average healing time was 6-8 weeks for the shaft of femur and tibiofibula,and 4-6 week for the humerus and shaft of radius. The internal fixation was removed 6 months later;the function of the affected limb and the neighboring joints were close to normal. Nail tail irritation and synovial sac formation occurred in 4 cases, which disappeared after removal of the implants. Conclusions：Titanic elastic nailing fixation is safe, effective and minimally invasive for treatment of children with long bone fracture with the advantages of faster healing and good functional recovery. The material deserves priority consideration for internal fixation.
