      in Patients With Degenerative Cervical Myelopathy: Results of a Systematic
      Review.

AB  - STUDY DESIGN: Systematic review. OBJECTIVES: To determine the preoperative
      computed tomography (CT) myelogram imaging parameters in patients diagnosed with 
      degenerative cervical myelopathy (DCM) that correlate with severity of DCM and
      predict postoperative patients' functional outcome. METHODS: An electronic
      database search was performed using Ovid Medline and Embase. CT myelogram studies
      investigating the correlation between imaging characteristics and DCM severity or
      postoperative outcomes were included. Two independent reviewers performed
      citation screening, selection, qualitative assessment, and data extraction using 
      an objective and blinded protocol. RESULTS: A total of 5 studies (402 patients)
      were included in this review and investigated the role of preoperative CT
      myelogram parameters in predicting the functional outcome after surgical
      treatment of DCM. All studies were retrospective cohort studies. CT myelogram
      characteristics included the transverse area of the spinal cord at maximum level 
      of compression, spinal canal narrowing, number of blocks, spinal canal diameter, 
      and flattening ratio. There is low evidence suggesting that patients with a
      preoperative transverse area of the spinal cord >30 mm2 at the level of maximum
      compression have better postoperative recovery and outcome. We found no studies
      investigating the correlation between preoperative CT myelogram parameters and
      DCM severity. CONCLUSIONS: Patients with greater transverse area of spinal cord
      at the level of maximum compression on the preoperative CT myelogram are more
      likely to have better neurological outcome after surgery. There is insufficient
      evidence to suggest that any of the other CT myelogram parameters investigated
      are predictors of postoperative outcomes in patients with DCM.
