A 16-year-old boy presented with segmental muscular atrophy of the bilateral distal upper extremities. Cervical spine x-ray films showed occult spina bifida from C-1 to T-1 associated with an abnormal long club-like bone located parallel to the epidural space between C-5 and C-7. In neck flexion, the cervical spinal cord was stretched and compressed to the posterior aspect of the vertebral body. Moreover, the dorsally placed abnormal bone migrated ventrally, indenting the dorsal portion of the spinal cord. This is quite an unusual case of so-called "flexion myelopathy," aggravated by the abnormal bone located dorsally.
一名16岁男孩出现双侧上肢远端节段性肌肉萎缩。颈椎X线片显示C-1至T-1隐性脊柱裂，伴有一根异常的长棒状骨，平行于C-5和C-7之间的硬膜外间隙。颈部屈曲时，颈脊髓被拉伸并向椎体后方受压。此外，位于背侧的异常骨向腹侧移位，压迫脊髓背侧部分。这是一例非常罕见的所谓“屈曲性脊髓病”，因背侧异常骨而加重。
