【摘要】 目的研究不同植入物内固定治疗股骨骨折后骨不连的临床疗效。方法 30例股骨骨折后骨不连患者作为研究对象,根据手术方式不同分为治疗A组与治疗B组,每组15例。治疗A组采取带锁髓内钉方式进行手术处理,治疗B组采取动力加压钢板处理,对比临床疗效。结果治疗A组患者手术时间(126.54±21.68)min,关节功能恢复优良率93.33%(14/15),并发症发生率6.67%(1/15);治疗B组患者手术时间(151.65±29.31)min,关节功能恢复优良率60.00%(9/15),并发症发生率40.00%(6/15);治疗A组手术时间、膝关节功能恢复优良率以及并发症发生率均明显优于治疗B组,差异具有统计学意义(P<0.05)。所有患者骨不连均未复发。结论股骨骨折后骨不连的治疗中采取带锁髓内钉处理,更符合现代生物力学及生理特征,具有创伤小、并发症发生率低,效果良好的优势,术式普适性广,值得推广应用。更多还原

【Abstract】 Objective To research clinical effects by different implants for internal fixation in the treatment of nonunion after femoral fracture. Methods A total of 30 patients with nonunion after femoral fracture as study subjects were divided by different surgery measures into treatment group A and treatment group B, with 15 cases in each group. Treatment group A received interlocking intramedullary nail for surgical treatment, and treatment group B received dynamic compression plate for treatment. Clinical effects were compared between the two groups. Results Treatment group A had operation time as(126.54±21.68) min, good rate of joint function recovery as 93.33%(14/15), and incidence of complications as 6.67%(1/15). Treatment group B had operation time as(151.65±29.31) min, good rate of joint function recovery as 60.00%(9/15), and incidence of complications as 40.00%(6/15). Treatment group A had obviously better operation time, good rate of joint function recovery and incidence of complications than treatment group B, and their difference had statistical significance(P<0.05). All patients showed no recurrent nonunion. Conclusion As a method meeting modern biomechanics and physiological features, interlocking intramedullary nail in the treatment of nonunion after femoral fracture contains advantages of small trauma, low incidence of complications and excellent effect. This method is worth promoting and applying due to its widely adaptable operation measure.更多还原
