About this trial
This study is comparing two FDA-approved cages used during lower back surgery. The study will look at whether one cage helps the bones in the back fuse together better than the other. Adults who are having a 1 or 2 level lumbar fusion surgery will be randomly assigned to receive either the Adaptix nanoPEEK cage or the Capstone PTC cage. Participants will have follow-up visits with imaging and questionnaires to evaluate bone fusion, back and leg pain, physical function, and overall health.
Eligibility criteria
