The significance of preoperative neurological disorders in predicting outcome of cervical spondylotic myelopathy after surgery.

The authors report the results of a large series of patients which underwent surgical treatment for cervical spondylotic myelopathy. In this retrospective study clinical findings before surgery are compared with results at the follow-up after two years; their significance as prognostic factors is investigated. Marked spasticity, prevalence of unilateral motor signs, presence of Brown-Sequard syndrome and of Lhermitte sign resulted valuable criteria in predicting outcome after surgery.
