Brief Summary

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

The purpose of this study is to evaluate the clinical, radiological, and surgical outcomes of the Annex™ Adjacent Level System for the treatment of adjacent level disease of the lumbar spine. The Annex™ Adjacent Level System is a spinal fixation system intended to be used with commercially available pedicle screw fixation systems in order to extend existing pedicle screw constructs. Subjects will be evaluated over a 2 year period and compared to historical control.
