RHINE™ Cervical Disc Clinical Study: A Prospective Observational Study for Patients Requiring 1-2 Level C-spine Surgery

Inclusion Criteria: * The patient requires reconstruction of the disc from C3 to C7 following discectomy at 1 or 2 (contiguous) levels for intractable radiculopathy (arm pain and/or a neurological deficit) with or without neck pain, or myelopathy due to abnormality localized to the level of the disc space and at least one of the following conditions confirmed by radiographic imaging (CT, MRI, X-rays): herniated nucleus pulposus, spondylosis (defined by the presence of osteophytes), and/or visible loss of disc height compared to adjacent levels. * The patient has failed at least 6 weeks of non-operative treatment or demonstrated progressive signs or symptoms despite non-operative treatment prior to implantation. * Self-reports a pre-operative upper extremity (right or left) VAS pain score ≥ 20 (0-100). * Self-reports pre-operative NDI score ≥ 30% (raw score of ≥ 15/50). * Willing and able to comply with the protocol requirements including follow-up visit schedule. * Willing and able to sign a study specific informed consent. Exclusion Criteria: * More than two cervical levels requiring surgery, or has two levels requiring surgery that are not adjacent. * Previous surgical intervention at the target level(s) * Any of the following at the target level(s): * Significant cervical anatomical deformity, e.g., ankylosing spondylitis, rheumatoid arthritis, etc. * Moderate to advanced spondylosis. Patients who demonstrate advanced degenerative changes characterized by any of the fol…
