Infuse Bone Graft for TLIF
Medtronic · FDA approval (expanded indication)
rhBMP-2 bone graft is now approved for one- and two-level TLIF.
The approval extends Infuse (recombinant human bone morphogenetic protein-2) to transforaminal lumbar interbody fusion at one or two levels from L2 to S1, with PEEK or titanium cages, in patients with up to grade 2 spondylolisthesis. A randomized trial of 493 patients comparing two rhBMP-2 doses with local autograft stopped enrollment early after meeting its primary endpoints. Medtronic reports fusion rates above 90% for single-level TLIF.
