Brief Summary:
CSM (Cervical spondylotic myelopathy) is the most common cause of spinal cord injury worldwide. While there is evidence from the recently completed SpineNet prospective study that surgical decompression is an effective treatment for CSM, it is clear that many patients have remaining neurological impairment. While surgery is relatively safe, approximately 3% of patients maintain a neurological problem. Given this background and data from preclinical models of non-traumatic and traumatic spinal cord injury, there is strong evidence to consider the potential benefit of adding a neuroprotective drug which aids in the treatment of patients with CSM whom are undergoing surgical decompression. Riluzole is FDA-approved for the treatment of amyotrophic lateral sclerosis, which has some similar clinical features to CSM. Riluzole is currently under investigation for traumatic spinal cord injury. Given this background, there is a strong basis to consider studying the potential neurological benefits of Riluzole as a treatment to surgical decompression in patients with CSM.

Primary Outcome Measures :
- Modified Japanese Orthopedic Association Score (mJOA) [ Time Frame: Before the surgery, 180 days ]The mJOA is a clinician administered scale. It evaluates four clinical dimensions; motor dysfunction score for upper and lower extremities, sensation loss and sphincter dysfunction. The total score ranges from 0 (worst) to 18 (best).
Secondary Outcome Measures :
- Nurick Score [ Time Frame: Pre-surgical, 180 days ]Nurick score is a simple measure of neurological dysfunction and ranges from 0 (best) to 6 (worst).
- SF-36v2.0 [ Time Frame: Before the surgery, 180 days ]The SF36v2.0 is a health-related quality of life instrument that evaluates health status accross eight health dimensions.
- Neck Disability Index (NDI) [ Time Frame: Before the surgery, 180 days ]The NDI evaluates patient self-reported functional outcomes related to neck conditions. The NDI score ranges from 0 (best) to 100 (worst).
- Cervical Pain Numeric Rating Scale [ Time Frame: Before the surgery, 180 days ]Simple numeric rating scale with choises of answers from 0 (no pain) to 10 (worst imaginable pain)
- EQ-5D [ Time Frame: Before the surgery, 180 days ]EQ-5D™ is a standardised instrument for use as a measure of health outcome. It provides a simple descriptive profile and a single index value for health status.
- American Spinal Injury Association Score (ASIA) [ Time Frame: Before the surgery, 180 days ]The ASIA impairment scale describes a person's functional impairment as a result of their spinal cord injury.
