## Indications for use
PMT Facet Fixation System (PMT FFS) is an integrated construct comprised of a CAVUX Cage and a single ALLY Bone Screw. PMT FFS is placed bilaterally through a posterior surgical approach and spans the interspace with points of fixation at each end of the construct. PMT FFS is intended for temporary stabilization as an adjunct to posterior cervical fusion in skeletally mature patients. PMT FFS is indicated for patients requiring a revision for an anterior pseudarthrosis at one level, from C3 to C7, with autogenous and/or allogenic bone graft.
