Intended Use

The Synthes Antegra-T System is indicated for use via the lateral or anterolateral surgical approach above the bifurcation of the great vessels or via the anterior surgical approach, below the bifurcation of the great vessels as an adjunct to fusion. This system is indicated in the treatment of lumbar and lumbosacral (LI - SI) spine instability as a result of fracture (including dislocation and subluxation), tumor, degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), pseudoarthrosis, spondylolysis, spondylolisthesis, scoliosis, lordotic deformities of the spine, spinal stenosis, or a failed previous spine surgery. Warning: This device is not intended for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

Device Story

Synthes Antegra-T System comprises one-level titanium lumbar/sacral plates and cancellous screws with locking heads; used for anterior/anterolateral spinal stabilization as adjunct to fusion. Plates range 37-53mm; sacral plates feature underside step for precise placement. System utilizes bone screws from predicate Antegra System. Intended for surgical implantation by physicians in clinical settings to treat spinal instability. Device provides mechanical fixation to stabilize vertebral bodies; benefits patient by facilitating fusion and correcting spinal alignment. Not for posterior pedicle fixation.

Clinical Evidence

No clinical data was required or provided for this device; substantial equivalence was demonstrated through non-clinical bench testing.

Technological Characteristics

Titanium alloy spinal intervertebral body fixation system. Includes one-level plates (37-53mm) and locking cancellous screws. Mechanical fixation device; no energy source or software components. Sterilization method not specified.

Indications for Use

Indicated for patients with lumbar and lumbosacral (L1-S1) spine instability due to fracture, tumor, degenerative disc disease, pseudoarthrosis, spondylolysis, spondylolisthesis, scoliosis, lordotic deformities, spinal stenosis, or failed previous surgery. Contraindicated for posterior element (pedicle) fixation.

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.
