1、山东入学硕士学位论文建立数据库并对结果进行统计描述和统计分析。统计分析方法:研究对象术前术后分组采用配对t检验,P<0.05为差异有显著性意义。结果计量资料采用均数±标准差(灶s),在行走实验中,术前患者出现脊柱矢状面失平衡症状的平均行走距离为514±109.86m,术后患者行走相同的距离时没有再出现脊柱矢状面失平衡症状。差异有统计学意义(P2、40。,脊柱后凸Cobb角的平均差值为:10.01±0.76。,差异有统计学意义(P<0.05)。所有患者进行随访,病人腰背部疼痛及矢状面失平衡症状明显缓解。所有患者行PKP后无严重的手术并发症发生。结论骨质疏松椎体压缩性骨折患者部分会出现脊柱矢状面失平衡症状,即站立行走或负重后感觉腰背部支撑不住,在行走或负重的过程中出现弯腰症状,影像学表现为脊柱后凸cobb角增大,C7铅垂线距S1后缘距离增大,病人行PKP手术后,脊柱后凸cobb角和伤椎楔形变角度均有变化,但脊柱后凸cobb角的变化明显大于楔形变角度的变化,说明患者出现脊柱矢状面失平衡非伤椎楔形变单一因素所致,而是脊柱骨折后腰3、背部的疼痛,限制了腰背肌的功能所致。且患者通过PKP手术后,脊柱矢状面失平衡症状往往会明显改善,通过此现象表明腰背肌力量受限是导致症状性脊柱矢状面失平衡的一个重要原因。关键词:压缩骨折;矢状面;失平衡;脊柱;PKP;骨质疏松山东大学硕士学位论文ThereasonsofthespinalsagittalimbalanceinpatientswithosteoporosisvertebralAbstractfracturescompressionPostgraduateZhangXiang—weiSupervisorProf.SunJian—rainProf.CuiXin—gangA4、BSTRACTBACKGROUND:Currently,spinalsagittalimbalancehasbecomeacommonclinicaldisease,butalsomultiplediseases,spinalimbalancesummaryofreasons,includingdomesticandspinaldeformity(congenitaloracquiredfactorsleadtokyphoisandscoliosisornerVemusclediseasescausedbypowerkyphosisandscoliosis),spinaldege5、nerativedisease(1umbardischerniation,lumbarspinalstenosis,spinalinfection,spinaltumors),osteoporoticvertebralcompressionfractures,etc,throughclinicalresearch,Webelievethatthepowerfactor(backmuscle)inspinalsagittalimbalanceplaysakeyrole,whicharerarelyreportedindomesticandaboard.OBJECTIVE:Byost6、eoporoticvertebralcompressionfracturesinpatientswithclinicalmanifestationsandtreatment,Analyzeandsummarizethereasonsofthespinalsagittalimbalance.METHODS:AretrospectiveanalysisofpatientstreatedbetweenJanuary2012toMay2013of127casesofspinalfractures,Selectingdiagnosedosteoporoticcompressionfract7、uresandhavingspinalsagittalimbalancesymptomsof41patients,AllpatientswereperformedPKPsurgery.9malesand32females,average65.8.Thepatiemsweregroupedaccordingtopreoperativeandpostoperative,patients3山东大学硕‘j:学位论文underwentpreoperativebonedensity,stan
