MagnetOs™ Granules vs. Autograft in Instrumented Posterolateral Spinal Fusion

Instrumented posterolateral spinal fusion, with or without an additional interbody device

8-10cc of MagnetOs™ Granules per spinal level at the randomized allocation side of the spine (left or right)

8-10cc autologous bone graft per spinal level at the control side of the spine (left or right). This can be a combination of local bone and iliac crest bone, but at least 50% of the volume has to be iliac crest bone graft.
