Brief Summary

This is a prospective, single arm clinical study to evaluate fusion status and patient reported outcomes utilizing the Stryker Tritanium® C Anterior Cervical interbody device at one or two contiguous levels. Subjects that are recommended for surgical treatment of either a 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) between the levels of Cervical Spine 2 to Thoracic 1 (C2-T1) and diagnosed with degenerative disc disease will be screened for the study.

Detailed Description

Degenerative disc disease of the cervical (neck) spine occurs when the discs between the vertebral bony bodies start to deteriorate or break down due to wear and tear over time. It is diagnosed as such once it is symptomatic and causes neck pain and radiculopathy (arm pain, weakness, and/or numbness). In order to correct the damaged disc and resolve radicular symptoms, anterior cervical discectomy and fusion surgery is commonly performed.

This is a prospective, single arm clinical study to evaluate fusion status and patient reported outcomes utilizing the Stryker Tritanium® C Anterior Cervical interbody device at one or two contiguous levels. Subjects that are recommended for surgical treatment of either a 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) between the levels of C2-T1 and diagnosed with degenerative disc disease will be screened for the study. Subjects will be followed up postoperatively per standard of care at 6-weeks, 3-monts, 6-months, 12-months and at 24-months at the private practice or hospital clinic. The primary end-point is Successful cervical spinal fusion as measured by dynamic (flexion and extension) x-rays and CT scan (using metal subtraction) at 12 months and as evidenced by the following three criteria: bony bridging, no presence of radiolucency, and no development of pseudoarthrosis at the treated cervical level.
