Avulsion and posterior dislocation of the posterior dislocation of the posterior part of the vertebral apophysis is a rare condition, occurring mainly in adolescence. If the avulsed part is ossified it may be diagnosed with conventional X-rays including myelography. The present case shows that CT scan with sagittal reconstruction gives exact information of the nature of the lesion as well as its extension into the spinal canal, and that CT alone is sufficient for preoperative diagnosis.
椎体骨骺后部撕脱并后脱位是一种罕见的病症，主要发生在青少年时期。如果撕脱部分已经骨化，可以通过包括脊髓造影在内的传统X线检查来诊断。本病例表明，矢状面重建的CT扫描能够提供关于病变性质及其向椎管内延伸情况的准确信息，而且仅CT扫描就足以进行术前诊断。
