Detailed Description

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

Single arm prospectively enrolled observational study of subjects who undergo lumbar spinal fusion at one or two levels with an anterior or lateral surgical approach using a cellular based allograft (Virtuos) as the bone graft There is no experimental intervention for this study. Subjects will be treated per standard of care by their attending physician/surgeon. The primary endpoint in this study is fusion success at 12 months. as determined by the attending physician/surgeon using CT as the imaging modality. The fusion rates observed at 12-months will be compared to an historical group of patients that underwent a one or two level lumbar fusion procedure with an anterior or lateral approach using a cellular based allograft (Trinity Elite).
