Surgical strategy for high-grade isthmic spondylolisthesis of 5th lumbar vertebrae

Objective To investigate surgical strategy for high-grade isthmic spondylolisthesis(more thanⅡ degree)of 5th lumbar vertebrae.Methods From August 2003 to October 2008,26 patients with high-grade isthmic spondylolisthesis (L5) were

第5腰椎横突肥大综合征的解剖学研究

目的 为第5腰椎横突肥大综合征提供解剖学基础.方法 用第5腰椎、骶骨各390块,测量第5腰椎横突、椎间孔的上下径和前后径.结果 第5腰椎横突正常上下径为13.3±2.6mm,前后径12.4±2.5mm正常椎间孔前后、上下径.第5腰椎肥大的横突上下径为20.9±2.4mm,前后径30.9±3.3mm.第5腰椎横突肥大L5～S1椎间孔的前孔,左侧:上下径11.5±4.3mm,前后径10.5±2.7mm;右侧:上下径10.2±4.5mm,前后径9.6±3.0mm.结论 第5腰椎横突肥大,可引起L5～S1椎间孔的前孔狭窄,累及第5腰神经,为腰腿痛的原因之一.
