目的：探讨钛制弹性髓内钉（titanium elastic nails,TENs）治疗儿童股骨干骨折的临床疗效。方法2010年4月~2012年4月在C型臂X光机下采用钛制弹性髓内钉治疗儿童股骨干骨折患者32例（男20例，女12例），年龄4~13岁，平均8岁，均采用闭合复位内固定，术后支具保护3w，平均住院8.5d。术后6个月内取出内固定，所有病例均获得1年零2个月以上的随访，随访内容包括伤口处疼痛情况、肢体长度、髋膝关节活动范围以及步态等情况。结果所有患者随访14~24个月，平均16个月。骨折均愈合，无严重并发症。术后无1例出现感染、针尾处红肿疼痛、骨折延迟愈合、不愈合、骨折处畸形、TENs折断、骨骺损伤等并发症。有2例出现双下肢不等长（<1.5cm），但无明显跛行，无髋膝关节功能障碍。根据Flynn评价标准，优良率达到100%。结论钛制弹性髓内钉（titanium elastic nails,TENs）治疗儿童股骨干骨折具有复位好、稳定性可靠、微创、愈合快、住院时间短、并发症少、患儿家长易于接受等多种优点，是治疗儿童股骨干骨折尤其合并肥胖症儿童的理想方法之一。“,”Objective To investigate the clinical ef ects of titanium elastic nails (TENs) to Treat the Femoral Shaft Fractures in children. Methods From April 2010 to April 2012,32 children were stabilized with TENs under C-arm observation,including 20 boys and 12 girls at average age of 8 years (range, 4~13years). Al the patients were treated with closed reduction. The average healing time was eight and a half days. Al the patients received the removal of the TENs six months after the surgery and were fol wed up for an average period of 14 months ,including wounds pain,limb length,hip and knee mobility and gait condition. Results Al the fractures were cured without serious complications. There were no postoperative complications like infections,swel ing pain around the nail tail,delayed uion,nonunion,limb deformities, nail broken and adjacent epiphyseal injuries. Unequal limb lengths occurred in 2 patients .But the two patients didn't show any limp and the dysfunctiong of the hip and knee joint.According to the Flynn evaluation standard, the excellent and good rate was 100%. Conclusion Treatment of Femoral Shaft Fractures in children. with Titanium Elastic Nails (TENs) has the advantages of satisfied reduction,reliable fixation,minimal y invasive,fast healing,short healing time,less complications. Futher more ,it is easy to be accepted by parents. TENs is an ideal options for treatment of femoral shaft fractures in children.
