    Abstract:
    OBJECTIVES: Cervical spondylotic myelopathy is usually a chronic and progressive disease. In a few cases, however, dramatic tetraplegia sometimes occurs after even minor injury. METHODS: We report seven patients (6 males, 1 female, aged from 41 to 63), who suffered from acute myelopathy after an injury. RESULTS: In 5 cases, the injury revealed the cervical spondylotic myelopathy. A hyperextension of the cervical spine was found in 5 cases. The injury was severe in only one case, but there was no bony abnormalities, except arthrosis. The most common cause was a fall. In contrast, severe tetraplegia was found in 4 cases. Spontaneous, but incomplete, recuperation occurred in 4 patients. In all 7 cases, CT scan and MRI showed congenital cervical stenosis associated with cervical spondylosis. The level of disco-osteophytic changes was mainly in C4, C5, C6. On T2-weighted spin-echo image, an increased signal intensity was present in the cord of 3 patients, but was not correlated with the severity of the symptoms, nor with improvement. Surgical treatment was performed in 6 cases: 3 laminectomies, 3 anterior or antero-lateral approaches. Improvement after operative decompression was observed in all but one case, even when the motor or sensory deficit persists for more than one year. Motricity of the inferior limbs improved better than the other deficits, perhaps because of the location of non-reversible lesions in the spinal gray matter. CONCLUSION: The acute medullary syndrome of cervical spondylotic myelopathy is serious and can cause major handicaps. This complication justifies a preventive surgical attitude when medullar signs are moderate, and cervical imagery shows a spondylotic compression of the cord with congenital stenosis.
