Neurological deterioration after reduction of cervical subluxation. Mechanical compression by disc tissue.
We report three patients with neurological deterioration after the reduction of cervical spine dislocation. In each case compression of the spinal cord by disc material was demonstrated by magnetic resonance imaging and recovery occurred following removal of the compressing disc. A separate radiological study suggested that disproportionate narrowing of the disc space implies disc extrusion; reduction of a dislocation showing this sign may produce or exacerbate neurological deterioration.
