单侧椎弓根钉内固定结合椎间融合术治疗腰椎间盘突出症疗效研究[摘要]目的:探讨单侧椎弓根钉内固定结合椎间融合术治疗腰椎间盘突出症的临床疗效及优势。方法:在2006年3月~2009年2月期间对52例腰椎间盘突出症的患者采用了内固定椎间融合器治疗,其中单侧椎弓根固定组24例,双侧椎弓根固定组28例。比较两种手术患者手术前后日本骨科协会评分(JapaneseOithopaedicAssociation,JOA)及腰痛指数(Oswestrydisabilityindex,ODI)、手术时间、术中出血量、术后住院天数、住院费用、融合率的情况。结果:术后随访12^20个月(平均16个月),两组患者术前JOA和0DI评分比较差异无统计学意义(P>0.05),末次随访时的JOA及0DI评分、融合率的差异也无统计学意义(P>0.05)o所有患者术后的功能参数均优于术前。单侧椎弓根固定组在手术时间、出血量、住院费用方面优于双侧椎弓根固定组(PV0.01)。结论:单侧椎弓根钉内固定结合椎间融合术治疗腰椎间盘突出症能够取得同双侧椎弓根钉内固定相同的手术效果,而且能够减少手术创伤,适于在临床应用。[关键词]腰椎间盘突出症;单侧;椎间融合术[中图分类号]R681.5[文献标识码]A[文章编号]1673-7210(2012)01(a)-047-03Effectsoflumbarinterbodyfusioncombinedwithunilateralpediclescrewfixationonlumbai'discherniationZHOULianjun,LIUYan,LIHaiyanDepartmentofOrthopaedics,DuodaoPeople'sHospitalofJingmenCity,HubeiProvince,Jingmen448124,China[Abstract]Objective:Toinvestigatetheclinicaleffectsofinternalfixationwithunilateralpediclescrewscombinedwithintervertebralfusioninlumbardischerniation.Methods:Frommarch2006toFebruary2009,52patientswithdischerniationweretreatedbyinternalfixationandintervertebralfusiondevice,therewas24casesininternalfixationwithunilateralradixarcusvertebraegroupand28casesinfixationwithbilateralradixarcusvertebraegroup・JapaneseOrthopaedicAssociation(JOA)scoreandOswestrydisabilityindex(ODI)scores,operationtime,bloodloss,hospitaldays,costofhospitalization,fusionratewerecomparedbetweenthetwogroups・ResuIts:Allpatientswerefollowedupfrom12to20months(averagewas16months).TherewasnosignificantdifferenceofthepreoperativeJOAandODIscoresbetweenthetwogroups(P>0.05);inthelastfollow—upvisiting,therewasnosignificantdifferenceoffusionrate,JOAandODIscoresbetweenthetwogroups(P>0.05).Thepostoperativedataofallpatientsweresignificantlybetterthanthosebeforesurgery.Theoperationtime,bloodlossandcostofhospitalizationofpatientswithunilateralradixarcusvertebraegroupweresignificantlybetterthanthoseofpatientswithbilateralradixarcusvertebraegroup(P<0.01).Conelusion:Theinternedfixationwithunilateraltranspediclescrewscombinedwithintervertebralfusionisaseffectiveasthatwithbilateralinstrumentsindischerniation,andoperativeinjuryislower,anditissuitabletoappallinginclinic・[Keywords]Lumbardischerniation;Urdlatered;Lumbarinterbodyfusion腰椎间盘突出症(lumbardischerniation,LDH)是骨科的常见病,占腰腿疼痛患者的25%~40%,我院2006年3月~2009年2月共对52例腰椎间盘突出症患者实施手术治疗,现报道如下:1资料与方法后正中纵形切口,依次剥离舐棘肌,暴露棘突、椎板、上下1.1一般资料两组患者共52例,其中,男22例,女30例。将纳入的病例分为单侧椎弓根固定组24例,其中,男10例,女14例;年龄40~70岁,平均50.5岁;病程6~60个月,平均20个月;累及病变节段L4~513例,L5^S111例。双侧椎弓根固定组28例,其中,男12例,女16例;年龄42〜75岁,平均52岁;病程6〜70个月,平均24个月;病变节段L4〜517例,L5〜S111例。两组患者年龄、性别、病程比较差异均无统计学意义(均P>0.05),具有可比性。1.2方法全身麻醉或硬膜外麻醉(全麻38例,硬膜外14例),俯卧位于脊柱外科手术架上,以髓核突出棘突间隙为中心作小关节突。单侧稚弓根...
