Myelopathy following cervical spine manipulation.

Manipulation of the spine, a controversial mechanotherapeutic procedure, has been taught and practiced widely. Occlusion of vertebral, basillar, and cerebellar arteries with head and neck manipulation is well documented in the literature. However, there is a paucity of references about myelopathy associated with cervical spine manipulation. Three cases of cervical myelopathy following spinal manipulation are presented. All patients noted increase in cervical pain following manipulation, developed significant sensary/motor deficits within 24 hours and became tetraparetic. Two patients were found to have fracture of C5 and C6 vertebral bodies. On myelography, partial block was noted in all and widening of the spinal cord was noted in two. One patient underwent excision of C5 vertebral body and anterior interbody fusion C4/6. Two patients underwent cervical laminectomy. Hematomyelia was present in one, and in the other patient the spinal cord was reported to be hyperemic and oedematous. Only one patient showed neurological return and became ambulatory, while the other two remained tetraparetic.
