In adolescents, on lateral radiographs of the vertebral column, the avulsion of a lumbar posterior ring epiphysis is a good argument suggesting a posterior herniation of the intervertebral disk. Two such cases are reported. The pathogeny of this tearing, unusual in adults, is discussed. This avulsion should be compared with the retromarginal anterior disk herniations, often observed at this age.
在青少年中，在脊柱的侧位X线片上，腰椎后环骨骺撕脱是提示椎间盘后突的有力证据。本文报告两例此类病例。文中讨论了这种在成人中不常见的撕裂的发病机制。这种撕脱应与这个年龄段常见的边缘后位椎间盘突出相鉴别。
