Lumbar Fusion With Nanotube Versus Titanium Cage

This study is a single‐center, single‐blind, randomized controlled superiority trial atthe University of Kentucky. The study will enroll adults who are undergoing a 1 or 2level transforaminal lumbar interbody fusion (TLIF) for degenerative disc disease.Participants will be randomly assigned in a 1:1 ratio to receive either the AdaptixnanoPEEK cage or the Capstone PTC cage during their lumbar fusion surgery. Both cages areFDA‐Approved and are used as part of the standard‐of‐care lumbar fusion surgery. Thestudy is comparing the outcomes of the two cages to determine whether one results inbetter spinal fusion outcomes.Participants will have follow‐up visits after surgery. X‐rays will be performed atfollow‐up visits and a CT scan will be performed at 6 months to evaluate the progress ofspinal fusion and the condition of the device and graft. An independent radiologist willreview the imaging. Participants will also complete questionnaires about disability,overall health, and back and leg pain. Follow‐up may continue for up to 24 months aftersurgery.
