腰椎椎体后缘骺环离断症的诊治

目的]了解腰椎椎体后缘骺环离断症的发病机理、临床表现和手术治疗。方法]对16例患有腰椎椎体后缘骺环离断症病人进行随访，对其临床表现、影像学检查进行分析，并对手术治疗的效果进行评估。结果]此病发病年龄较轻，临床表现为腰椎间盘突出及椎管狭窄的症状，根据突出的范围和类型可采取不同的手术方法，手术治疗效果良好。结论]通过CT检查可把腰椎椎体后缘骺环离断分为软骨板破裂后移型、Schmorl结节型、撕脱骨折型3种类型，手术治疗可取得良好效果．

Diagnosis and treatment of the posterior margin separation of lumbar vertebral epiphysis

Objective]To study the pathogenesis,clinical manifestation and surgical treatment of the posterior margin separation of lumbar vertebral epiphysis.Method]Sixteen patients suffering from the posterior margin separation of lumbar vertebral epiphysis were followed up.The clinical manifestation and radiologic examination were analyzed and results of surgical treatment were evaluated.Result]The patients were usually young and manifested with the sign and symptom of lumbar disc herniation and/or lumbar stenosis.CT was helpful for the accurate diagnosis of this disease.The different surgical measures were taken for the treatment according to the type and range of protrusion.Conclusion]The posterior margin separation of lumbar vertebral epiphysis were divided into three types:end plate separation and moving into posterior margin,Schmorl node and avulsion fracture.The good results can be obtained with surgery.
