【摘要】 目的:探究镍钛记忆合金弓齿钉内固定治疗第五跖骨基底部骨折的疗效,为临床治疗方法的选择提供理论依据。方法:回顾性分析本院2014年3月-2016年4月收治的80例第五跖骨基底部骨折患者的临床资料。依据治疗方式不同将其分为观察组和对照组,每组各40例。观察组采用镍钛合金弓齿钉内固定治疗,对照组则采用石膏外固定治疗。术后3个月对两组骨折愈合时间、愈合率、愈合程度(AOFAS评分及VAS评分)及并发症进行比较。结果:观察组平均愈合时间为(4.9±1.3)周,明显短于对照组的(7.9±1.1)周(P<0.05)。观察组39例完全愈合,对照组32例完全愈合,两者对比差异有统计学意义(P<0.05);观察组2例出现并发症,对照组8例(P<0.05)。观察组AOFAS评分为(94.36±5.27)分,对照组为(87.10±6.31)分,两组比较差异有统计学意义(P<0.05);观察组VAS评分为(0.87±0.25)分,对照组为(1.42±0.45)分,两组比较差异有统计学意义(P<0.05)。结论:对第五跖骨基底部骨折患者行镍钛合金弓齿钉内固定治疗的临床总有效率优于外固定治疗,并发症较少,推荐临床广泛应用。更多还原

【Abstract】 Objective:To explore effect of nickel titanium memory alloy bow tooth nail internal fixation on the treatment of the fifth metatarsal basal part fractures and to provide a theoretical basis for clinical on thefifth metatarsal bone fracture treatment methods.Method:From March 2014 to April 2016,a total of 80 fracture cases in the base of the fifth metatarsal in our hospital were divided into the observation group and control group according to different treatment methods,40 cases in each group.The observation group was treated with nickel titanium alloy bow tooth nail internal fixation,the control group was treated with plaster external fixation.After operation,the healing time,healing rate,healing degree( AOFAS score and VAS score) and the incidence of complications of the two groups were compared and analyzed.Result:After observation of 2-12 weeks,the average healing time of the observation group was significantly shorter than that of the control group,the difference was statistically significant(P<0.05).In the observation group,39 cases were healed,while 32 cases were healed in the control group,the difference had statistical significance( 字2=6.13,P<0.05);2 cases had complications in the observation group,8 cases had complications in the control group,the difference was statistical significance(P<0.05).AOFAS score of the observation group was( 94.36±5.27)score,the control group of that was(87.10±6.31) score( P<0.05).VAS score of the observation group was( 0.87±0.25) score,the control group was of that( 1.42±0.45) score(P<0.05).Conclusion:Compared with plaster external fixation,nickel titanium alloy bow tooth nail internal fixation has higher efficiency,better curative effect and fewer complications in treatment of the fifth metatarsal basal part fracture.It is recommended to a wide range of clinical applications.And it opens the new era in the field of treatment for the fractures of the fifth metatarsal.更多还原
