腰椎椎体后缘骺环离断症的诊治

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

[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。

[ 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.
