Allograft for TLIF Surgery
Mon, 09/10/2007 - 5:21am
The VERTIGRAFT® VG2® TLIF Allograft is a new bone product designed to facilitate graft insertion and bone growth during transforaminal lumbar spinal fusion (TLIF) surgery. Developed in partnership with LifeNet®, the machined allograft is comprised of both cortical bone, which provides strength, and cancellous bone, which can promote osteoconductivity. The allograft is made up of two cortical bone planks (3 mm each) surrounding a 3-mm plank of cancellous bone at the core. The cortical bone provides biomechanical strength, and holds the vertebral bodies in place while the porous, cancellous core facilitates bone growth. The construct has pyramidal teeth that are designed to prevent migration in the disc space. The VG2 TLIF Allograft’s lordotic implants have offset angles that provide 5 degrees of lordosis when positioned 35 degrees to midline.
