扩髓交锁髓内钉治疗胫骨上段骨折的疗效分析

Clinical effect of reamed interlocking intramedullary nail in the treatment of upper tibial fracture

目的 探讨扩髓交锁髓内钉治疗胫骨上段骨折的疗效及安全性.方法 采用随机数字表法将胫骨上段骨折患者81例分成观察组（扩髓交锁髓内钉治疗）41例和对照组（非扩髓交锁髓内钉治疗）40例.观察并比较两组手术时间、愈合时间、锁钉断裂情况、骨折愈合情况及感染情况.结果 观察组手术时间（55.3±19.2）min,明显长于对照组的（44.7±12.4）min;愈合时间（16.2±4.2）周,明显短于对照组的（24.1±5.2）周,差异均有统计学意义（t=6.543、8.235,均P〈0.05）.在锁钉断裂、骨折愈合方面,两组间差异均无统计学意义（χ2=0.086、0.753、0.633、0.598,均P〉0.05）.结论 扩髓交锁髓内钉治疗胫骨上段骨折具有可靠的疗效,内固定更加稳定,患者术后愈合速度更快.

 Objective To evaluate the efficacy and safety of reamed interlocking intramedullary nail in the treatment of upper tibial fracture .Methods According to the random number table ,81 patients with tibial fracture were divided into observation group （ reaming intramedullary interlocking nails ） of 41 cases and control group （unreamed intramedullary nails） of 40 cases.The operation time,healing time,fracture of nail lock,fracture union and infection were observed and compared between the two groups .Results The operation time of the observation group [（55.3 ±19.2）min] was significantly longer than that of the control group [（44.7 ±12.4）min].The healing time of the observation group [（16.2 ±4.2） weeks] was significantly shorter than that of the control group [（24.1 ± 5.2）weeks],the differences were statistically significant （t=6.543,8.235,all P〈0.05）.The fracture of the nail, fracture healing were compared between the two groups,the differences were not statistically significant（χ2=0.086,0.753, 0.633,0.598,all P〉0.05）.Conclusion Reamed interlocking intramedullary nail in the treatment of upper tibial fracture has reliable curative effect .The internal fixation is more stable and the healing rate of the patients is faster .
