Review Comparative Study
Outcomes after laminoplasty compared with laminectomy and fusion in patients with cervical myelopathy: a systematic review.
Systematic review. ⋯ Weak.

Post hoc analysis of prospectively collected data. ⋯ This study is the first to correlate cervical sagittal balance (C2-C7 SVA) to myelopathy severity. We found a moderate negative correlation in kyphotic patients of cord volume and cross-sectional area to mJOA scores. The opposite (positive correlation) was found for lordotic patients, suggesting a relationship of cord volume to myelopathy that differs on the basis of sagittal alignment. It is interesting to note that sagittal balance but not kyphosis is tied to myelopathy score. Future work will correlate alignment changes to cord morphology changes and myelopathy outcomes. SUMMARY STATEMENTS: This is the first study to correlate sagittal balance (C2-C7 SVA) to myelopathy severity. We found a moderate negative correlation in kyphotic patients of cord volume and cross-sectional area to mJOA scores. The opposite (positive correlation) was found for lordotic patients, suggesting a relationship of cord volume to myelopathy that differs on the basis of sagittal alignment.

Literature review. ⋯ In the vast majority of cases, magnetic resonance imaging was an invaluable tool in determining the correct diagnosis. Electrodiagnostic studies, cerebrospinal fluid profile, unique symptomatology, and consideration of patient demographics can also aid in the diagnosis. Bilateral sensory complaints in the hands are suspicious for cervical cord pathology and MR imaging of the same should be done even if the electromyography/nerve conduction studies (NCS) suggest bilateral carpal tunnel syndrome. SUMMARY STATEMENTS: Physical exam findings are not always consistent with severity of disease in CSM; therefore, correlation to plain radiographs, MRI, and patient symptomatology is essential for arriving at the correct diagnosis. In some cases where these studies are still equivocal, use of other studies should be considered including electrodiagnostic studies as well as cerebrospinal fluid examination.

Retrospective analysis of a prospectively collected database. ⋯ Disc herniations represent a significant cause of morbidity in the NFL. Although much attention is placed on spinal cord injuries, preventive measures targeting the cervical, thoracic, and lumbar spine may help to reduce the overall incidence of these debilitating injuries.Level of Evidence: N/A.
