Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose The primary purpose of this study is to prospectively compare clinical and radiographic clinical outcomes in patients undergoing cervical or lumbar interbody fusions and randomized to receive either polyetheretherketone (PEEK) or cortical allografts.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Following surgery study subjects will be evaluated at the following intervals: 3 (+/- 2 weeks), 6 (+/- 1 month), 12 (+/- 2 months), 24 (+/- 2 months) months.
