Principal Investigator: Michael Oh
Official Title: Prospective, Randomized, Controlled, Blinded Pivotal Study In Subjects Undergoing A Transforaminal Lumbar Interbody Fusion (TLIF) At One Or Two Levels Using Infuse Bone Graft and The Capstone Spinal System With Posterior Supplemental Fixation For The Treatment Of Symptomatic Degenerative Disease Of The Lumbosacral Spine
A Study On:
