The purpose of this study is to evaluate the efficacy of SeaSpine Shoreline device in surgery of the cervical spine.

This is a retrospective, prospective, post-market, observational, single-center, single surgeon study evaluating the use of the SeaSpine Shoreline device. Patients will be identified by the Investigator as needing, or already received the device during a cervical fusion surgery and meeting all the inclusion and none of the exclusion criteria.

Inclusion Criteria:

1. Appropriate patient, as determined by the Investigator, scheduled for an elective cervical spine fusion to treat adjacent level cervical disc herniation or degeneration resulting in cervical radiculopathy or myelopathy
2. At least 18 years of age
3. Failure of nonoperative care
4. Previous anterior cervical plating
5. Psychosocially, mentally and physically able to comply with this protocol including adhering to follow-up schedule and study requirements

Exclusion Criteria:

1. Pregnancy or anticipated to become pregnant during the course of the study
2. No previous cervical spine surgery
3. Non-instrumented cervical fusion
4. Cervical fusion with separate plate fixation
5. Unwilling or unable to sign consent
6. Patient has any condition, that in the opinion of the Investigator, would prohibit the patient from complying with the protocol
7. Currently a prisoner

A patient who meets all inclusion criteria and none exclusion criteria will be enrolled in the study. A patient is considered enrolled upon placement of the SeaSpine Shoreline device during the surgical procedure. If the surgeon decides intra-operatively not to utilize the SeaSpine Shoreline device, the patient will be considered a screen failure.
