Summary

This trial is designed to assess the safety and effectiveness of MagnetOs Putty as a bone graft extender mixed with autograft in patients undergoing posterior lumbar interbody fusion (PLIF), transforaminal lumbar interbody fusion (TLIF), or lumbar interbody fusion (LIF).

Who is the study for?
This trial is for adults over 18 with degenerative disc disease needing a two-level spinal fusion surgery, who have tried other treatments like physical therapy or medications for at least 3 months without success. It's not suitable for pregnant women, those with previous surgeries at the same spine levels, infections in the area, bone diseases affecting healing, or anyone involved in litigation related to their spinal condition.
What is being tested?
The study compares MagnetOs Putty—a synthetic bone graft extender—with Demineralized Bone Matrix mixed with autograft bone. Patients undergoing lumbar fusion surgery will receive these materials to see how well they help the spine heal and fuse compared to each other.
What are the potential side effects?
While specific side effects are not listed here, typical risks of using bone graft extenders include infection risk at the surgical site, inflammation around the area where it's applied, potential allergic reactions to materials used and complications related to improper spine fusion.
