扩张自锁髓内钉与交锁髓内钉治疗胫骨干闭合骨折的临床比较研究

目的对比髓内扩张自锁髓内钉固定术(self-locking expandable intramedullary nail)与交锁髓内钉内固定术(interlocking in-tramedullary nail)治疗胫骨干闭合骨折的临床结果,并探讨髓内扩张自锁髓内钉技术要点。方法治疗胫骨骨折31例,其中自锁髓内钉组15例,交锁髓内钉组16例。记录手术时间、术中出血量、术中X线机透视次数、术中术后并发症、下地时间,骨折愈合时间、术后1年膝关节KSS评分结果。结果随访15～21个月。自锁髓内钉组、交锁髓内钉组手术时间分别为(32±17)min,(58±21)min,P0.05]、术中出血量(71±25)ml,(145±31)ml,P0.05)]、术中X线透视次数(6±2)次,(14±6)次,P0.05)],术中术后并发症发生率、下地时间、骨折愈合时间、术后1年膝关节KSS评分无显著性差异。结论胫骨干闭合骨折是髓内扩张自锁髓内钉固定术的适应证,该术较交锁髓内钉术更微创,手术时间短,治疗效果与交锁髓内钉术大致相当,但其远期效果需要进一步临床研究。

Comparative Research on Sclf-llock Expandable Intramedullary Nail and Interlocking Intramedullary Nail in Treatment of Tibial Shaft Closed Fractures

Objective To investigate and discuss the feasibility and clinical outcome of self-locking expandable intramedullary nail and interlocking intramedullary nail in the treatment of tibial shaft closed fracture.Methods Thirty-one cases were recorded.In self-locking expandable intramedullary nail group,15 cases were operated.In interlocking intramedullary nail group,16 cases were operated.Time of operation,the intra-operative blood loss,the rate of complications,time of leave bed,time of bone union,the KSS score...
