Indications for Use

The ORION® Anterior Cervical Plate System is intended for anterior interbody screw fixation of the cervical spine. The system is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), trauma (including fractures), tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudarthrosis, and/or failed previous fusions. Warning: This device is not approved for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic or lumbar spine.

Device Story

ORION® Anterior Cervical Plate System consists of titanium alloy bone plates and screws; used for anterior cervical intervertebral body fusion. Surgeon implants plates onto anterior cervical spine; inserts bone screws through plate openings into vertebral bodies for fixation. Locking screws secure positioning of primary screws; central slots/holes accommodate additional screws for enhanced vertebral/bone graft purchase. Associated instruments facilitate implantation. Device provides temporary stabilization during fusion development. Used in clinical settings by surgeons. Benefits include spinal stabilization for patients with degenerative disc disease, trauma, tumors, or deformity. Not for posterior pedicular attachment.

Clinical Evidence

Bench testing only.

Technological Characteristics

Titanium alloy (ASTM F-136 or ISO 5832-3). System includes bone plates, bone screws, and locking screws. Mechanical fixation via anterior vertebral body screw placement. Sterile or non-sterile supply.

Indications for Use

Indicated for temporary stabilization of anterior cervical spine during fusion in patients with degenerative disc disease, trauma (fractures), tumors, deformity (kyphosis, lordosis, scoliosis), pseudarthrosis, or failed previous fusions. Contraindicated for posterior pedicular screw 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.
