摘要
目的探讨弹性髓内针直径(ND)与髓腔峡部直径(MCD)的比值在儿童股骨干骨折治疗中的应用价值。方法将90例采用弹性髓内针固定治疗的股骨干骨折患儿按照ND/MCD的不同分为观察组(30%≤ND/MCD<40%,47例)和对照组(ND/MCD≥40%,43例)。比较两组围手术期指标、取出内固定手术时间、骨折愈合情况、膝关节屈曲活动度。结果患儿均获得随访,时间6~10(8.16±0.57)个月。术中出血量、手术时间、住院时间、取出内固定手术时间、骨折愈合时间观察组均少(短)于对照组(P<0.05);开始下地时间、骨痂形成时间、术后3个月及6个月膝关节屈曲活动度、术后并发症发生率两组比较差异均无统计学意义(P>0.05)。结论选择30%≤ND/MCD<40%的弹性髓内针固定治疗儿童股骨干骨折,手术操作更为方便,且术中出血量较少,手术时间及取出内固定手术时间较短,住院时间及骨折愈合时间较短,早期临床效果满意。
Objective To investigate the application value of ratio of elastic intramedullary nail diameter(ND)to medullary canal diameter(MCD)in the treatment of femoral shaft fractures in children.Methods The 90 children of femoral shaft fractures treated with elastic intramedullary nails fixation were divided into an observation group(30%≤ND/MCD<40%,47 cases)and a control group(ND/MCD≥40%,43 cases),according to different ND/MCD levels.The perioperative indicators,surgical time of removing internal fixation,fracture healing and knee flexion mobility were compared between the two groups.Results All patients were followed up for 6~10(8.16±0.57)months.The intraoperative bleeding volume,surgical time,hospitalization time,surgery time of removing internal fixation and fracture healing time in the observation group were all lower(shorter)than those in the control group(P<0.05);there were no statistical differences between the two groups in terms of the start of mobilization,time of callus formation,knee flexion range of motion at postoperative 3,6 months,and incidence rate of complications(P>0.05).Conclusions For the treatment of femoral shaft fractures in children,choosing an elastic intramedullary nail with a diameter of 30%≤ND/MCD<40%is more convenient for surgical operation,with less intraoperative bleeding,shorter surgical time and removal of internal fixation,shorter hospital stay,shorter fracture healing time,and satisfactory early clinical results.
