A 12-year-old girl with a spastic dystonic tetraparesis due to cerebral palsy showed a subacute cervical myelopathy. X-ray films of the cervical spine demonstrated a subluxation of C4 on C5. Myelography and computerized tomography of the cervical spine performed under general anesthesia demonstrated only a minimal rotation of C3 with respect to C4 and a rather narrow cervical canal. In the reported case the most important factor in the spinal cord impairment was probably the anterior-slipping of the 4th cervical vertebra. The subluxation, secondary to torsion dystonia as demonstrated by its relief during general anesthesia, very likely caused a long-standing, although intermittent, spinal cord compression.
一名因脑瘫导致痉挛性肌张力障碍性四肢轻瘫的12岁女孩出现亚急性颈髓病。颈椎X线片显示C4椎体相对于C5椎体半脱位。在全身麻醉下进行的颈椎脊髓造影和计算机断层扫描仅显示C3相对于C4有轻微旋转，且颈椎管相当狭窄。在该报道病例中，脊髓损伤的最重要因素可能是第4颈椎椎体的前滑脱。如全身麻醉期间病情缓解所显示的，继发于扭转性肌张力障碍的半脱位很可能导致了长期（尽管是间歇性的）脊髓压迫。
