Experimental: Synergy Disc
The Synergy Disc is a cervical disc prosthesis that can be inserted between C3-C7 in skeletally mature patients after anterior discectomy to provide restoration of motion to the functional spinal unit. The Synergy Disc is designed to restoring kinematics to the cervical spine. The Synergy Disc is intended for use in the cervical spine for reconstruction of the disc following a single level discectomy for intractable radiculopathy and/or myelopathy.
Device: Anterior Cervical Discectomy & Fusion
Other Name: ACDF
- NDI [ Time Frame: 24 Month ]≥ 15-point improvement in NDI Score (out of 100) in subjects at 24 months compared with baseline
- Neurological Assessment [ Time Frame: 24 Month ]Maintenance or improvement in neurological status (motor and sensory only) at 24 months compared to baseline
- SSI [ Time Frame: 24 Month ]No study failure due to secondary surgical interventions (revision, removal, re-operation, supplemental fixation) at the index level
- Device Related AE [ Time Frame: 24 Month ]Absence of major device related adverse events defined as radiographic failure, neurological failure, or failure by adverse event as adjudicated by the CEC.
- SF-3 [ Time Frame: 6 Week, 3, 6, 12, and 24 Month ]Health Survey (SF-36) at baseline and at each follow-up time-point
- VAS [ Time Frame: 6 Week, 3, 6, 12, and 24 Month ]Visual analogue scale (VAS) will be used to evaluate pain where a change of at least 20mm will be considered clinically significant. Neck pain as measured on a 100mm VAS at baseline and at each follow-up time-point. Left and Right arm/shoulder pain as measured on a 100mm VAS at baseline and at each follow-up time-point. Please note, this assessment will include a "Worst" to pool together the left or right arm/shoulder scores with the higher baseline score. VAS Hoarseness on a 100mm scale.
- Patient Satisfaction [ Time Frame: 6 Week, 3, 6, 12, and 24 Month ]Patient Satisfaction Questionnaire
- BZ Score [ Time Frame: 6 Week, 3, 6, 12, and 24 Month ]Bazaz Dysphagia Score at 24 months compared to baseline
- Odom's Criteria [ Time Frame: 6 Week, 3, 6, 12, and 24 Month ]Results at 24 months for the investigational Synergy Disc and at 24 months for the control ACDF will also be categorized by the physician according to Odom's Criteria.
