Fusion Rate of Biphasic Calcium Phosphate Bone Graft with Needle-Shaped Submicron Surface Topography in Interbody Lumbar Fusion for Degenerative Disc Disease: A Single-Center Retrospective Review

This study demonstrates a high fusion rate (95.70%) and low complication rate in a diverse patient population with multiple comorbidities, suggesting BCP<μm is a viable graft material for lumbar interbody fusion.
