摘要
本文回顾了110例脊柱外伤病例,其中暴裂性椎体骨折47例,单纯性椎体压缩骨折36例,其他损伤(骨折并/或脱位)27例,分析其椎体后缘线在X 线上的表现。正常的椎体后缘线在X线侧位片上表现为单边或双边的垂直线.本研究中26例单纯性暴裂椎体骨折均发现椎体后缘线破裂、移位成角、旋转或消失,21例以暴裂性椎体骨折为主的损伤中19例有这种异常;而36例单纯性椎体压缩骨折和其他损伤27例均未发现该异常.CT 检查可确定椎体后缘断裂和椎管内骨折碎片.椎体后缘线的破裂是平片诊断暴裂性椎体骨折的可靠征象,并提示椎管和蛛网膜下腔受损.
A review of 47 cases with vertebral bodyburst fractures and 36 cases with simple anteri-or body compression fractures was performed to evaluate the integrity of the posterior vertebralbody margins in the lateral radiologic films.Asingle or double vertebral lines shown on thelateral radiologic films normally,versus to thedisruption,displacement,obliteration or rotationof the vertebral body lines were found in all 26cases with“pure”burst fractures.Thses abnor-malities were also present in 19 of the 21 caseswith comined fractures,but the continuity ofthe lines were maintained in all cases with sim-ple compression fractures.CT studies showeddisruption of posterior vertebal body marginsand bone fragments within the vertebralcanals.The disruption of the posterior vertebralbody line is a reliable diagnosing plain-film signfor the presence of burst fracture,sometimes,ccmpromising the vertebal canal and subarch-noid space.
