The purpose of this study is to determine the relevant significance of diabetes on cervical disc degeneration, and correlate diabetic control (HgbA1C) with disc glycosylation profile in patients undergoing anterior cervical discectomy and fusion for cervical spondylosis. Additionally, to compare the level of degenerative cervical disc glycosylation in patients with and without diabetes. Hypothesis: Patients with diabetes and degenerative cervical disc disease have higher levels of disc tissue glycosylation, and higher levels of glycosylation are correlated with poor outcomes.
