摘　　要：作者诊治了１３例腰椎椎体后缘离断症，其主要症状为腰腿痛与间歇性跛行，少数发生马尾压迫综合征。１３例共有１４个腰椎椎体的后缘形成突向椎管内的骨块，８个与椎体相连，６个与椎体分离，与其相对应的椎体后角骨缺损区内为椎间盘髓核组织；８个椎体后角的病损构成７例患者中央管或神经根管狭窄的主要原因，另６个椎体后角病损较小，仅部分参与神经根压迫；病变主要见于Ｌ４，５及Ｓ１椎体后上缘或下缘。作者认为成人中所见椎体后缘离断的征象很可能是青少年时期椎体后缘环状骨骺变异或陈旧性损伤及其继发改变的结果。Thirteenadultpatientswithposteriorbonyseparationoflumbarvertebraewerestudied.Thecommonsymptomsofthediseasewerebackandlegpain,intermitentneurogenicclaudication,orcaudaequinasyndrome.Therewerefourteenavulsedorseparatedbodiesattheposterioredgesoflumbarvertebraewhichprotrudedintothespinalcanal.Ofthese,eighthadbonyconnectionwiththevertebraeandsixhadscartisueconnection.Correspondingtothebonyavulsionregion,therewasbonydefectfiledwithdiscmaterialintheposteriorpartofthevertebrae.Thelesionsasthemainreasonleadtothecentralorrootstenosisinseven,andasapartialreasonresultedinthenerverootcompresioninanothersix.Mostoflesionslocatedinthepostero superiororinferioredgesoftheL4,L5andS1vertebrae.Theauthorsconsideredtheposiblereasonforthedis easemightbeasecondarychangesoftheinjuryorvarianceoftheepiphysealringofthevertebralbodyduringtheadolescentperiod.
