带锁髓内钉治疗四肢创伤骨折后骨不连的临床效果探究

The Clinical Effect of Interlocking Intramedullary Nail in the Treatment of Nonunion after Trauma Fracture of Extremities

目的探究带锁髓内钉治疗四肢创伤骨折后骨不连的临床效果。方法于2019年1—10月共选取该科室62例四肢创伤骨折后骨不连患者进行该次研究,选用电脑随机数字法,将研究对象分为两组,对比组31例,研究组31例,对比组进行动力加压钢板固定,研究组进行带锁髓内钉固定,分析两组的手术指标数据。结果数据结果显示:研究组手术时间为(136.7±32.5)min,对比组为(160.4±36.2)min(t=2.712,P=0.008);研究组术中输血量为(347.2±126.3)mL,对比组为(469.8±117.5)mL(t=3.957,P=0.000);研究组术后引流量(90.8±22.4)mL,对比组(167.9±36.9)mL(t=9.944,P=0.000);研究组骨折愈合时间为(23.4±3.2)周,对比组为(32.7±3.7)周(t=10.585,P=0.000),各项对比差异有统计学意义(P<0.05);研究组手术切口长度为(16.3±2.3)cm,对比组为(17.2±2.5)cm,差异无统计学意义(t=1.475,P=0.145>0.05)。结论在四肢创伤骨折后骨不连患者中进行带锁髓内钉固定治疗,有较好的临床治疗效果且不易发生并发症,在临床的实用价值显著。

Objective To explore the clinical effect of interlocking intramedullary nails in the treatment of nonunion after traumatic fracture of extremities.Methods Case selection time:January to October 2019,a total of 62 patients with nonunion of the limbs after trauma fracture of the extremities were selected for this study.The computer random number method was used to divide the research subjects into 2 groups.There were 31 cases in the control group and 31 cases in the study group.The control group was fixed with dynamic compression plate,and the study group was fixed with intramedullary nail.The surgical index data of the two groups were analyzed.Results The data showed that the operation time of the study group was(136.7±32.5)min,the control group was(160.4±36.2)min(t=2.712,P=0.008);the intraoperative blood transfusion of the study group was(347.2±126.3)mL,(469.8±117.5)mL in the comparison group(t=3.957,P=0.000);postoperative drainage(90.8±22.4)mL in the study group,(167.9±36.9)mL in the comparison group(t=9.944,P=0.000);the fracture healing time of the study group was(23.4±3.2)weeks,and that of the comparison group was(32.7±3.7)weeks(t=10.585,P=0.000).There was a statistically significant difference between each comparison(P<0.05).The length of the surgical incision in the study group was(16.3±2.3)cm,and that in the control group was(17.2±2.5)cm(t=1.475,P=0.145).There was no statistically significant difference in comparison(P>0.05).Conclusion Intramedullary nail fixation in patients with nonunion after trauma of extremities has good clinical treatment effect and is not prone to complications.It has significant clinical value.
