The VertiForm Posterior Fixation System is intended for posterior, non-cervical fixation
in skeletally mature patients for the following conditions: degenerative disc disease
(DDD), DDD is defined as back pain of discogenic origin with degeneration of the disc
confirmed by patient history and radiographic studies, spondylolisthesis, trauma
(fracture or dislocation), spinal stenosis, curvatures (scoliosis, kyphosis, lordosis),
tumor, pseudarthrosis (previous failed fusion). When used as posterior non-cervical
pedicle screw fixation in pediatric patients, the Vertiform Posterior Fixation System is
intended to treat adolescent idiopathic scoliosis. The device is intended to be used with
autograft and or allograft to facilitate fusion.
Indications for use as stated in the FDA summary.
