## Indications for use
PMT Expandable Cage (PMT EXP) is an integrated construct comprised of a CAVUX Cage-E and a single ALLY Screw-E. PMT EXP is placed bilaterally through a posterior surgical approach and spans the facet interspace with points of fixation at each end of the construct. PMT EXP is intended for temporary stabilization as an adjunct to single level posterior cervical fusion in skeletally mature patients. PMT EXP is only intended for use with a single level anterior cervical fusion at the same spinal level that utilizes FDA cleared/approved spine stabilization hardware for anterior cervical fusion procedures. PMT EXP is indicated for the treatment of patients with cervical degenerative disc disease (DDD) with radiculopathy from C3-C7. PMT EXP is indicated for use with autogenous and/or allogenic bone graft.
