Product Description: The DIVERGENCE™ Anterior Cervical Fusion System consists of temporary implants (plates and bone screws) intended for anterior screw fixation, and fusion devices (interbody cages) intended to stabilize and promote bone fusion during the normal healing process following surgical correction of disorders of the spine. The DIVERGENCE™ anterior cervical plates and bone screws are available in broad range of size offerings that are intended for anterior screw fixation intended for {1}------------------------------------------------ stabilization use during the normal healing process following surgical correction of disorders of the spine. Fixation is provided by bone screws inserted into the vertebral body of the cervical spine using an anterior approach. The DIVERGENCE™ anterior cervical plate and bone screws are made from titanium allov and are provided sterile. The DIVERGENCE™ anterior cervical cages available in various widths and heights can be inserted between two cervical vertebral bodies to give support and correction during cervical interbody fusion surgeries. The hollow geometry of the implants allows them to be packed with autogenous bone graft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft. These implants must be used with supplemental fixation. The device is made from medical grade polyetheretherketone (PEEK OPTIMA™), contains titanium alloy wire markers and is provided sterile. #### VII. Indications for Use: The DIVERGENCE™ anterior cervical plate and bone screw components are intended for anterior interbody screw fixation from C2-T1. The plate and bone screw components are indicated for use in the temporary stabilization of the anterior spine during the development of 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), 2) trauma (including fractures), 3) tumors, 4) deformity (defined as kyphosis, or scoliosis), 5) pseudoarthrosis, and/or 6) failed previous fusions. The DIVERGENCE™ anterior cervical cage component is intended to be used for anterior cervical interbody fusion procedures in skeletally mature patients with cervical disc disease at one level from the C2-C3 disc to the C7-T1 disc. Cervical disc disease is defined as intractable radiculopathy and/or myelopathy with herniated disc and/or osteophyte formation on posterior vertebral endplates producing symptomatic nerve root and/or spinal cord compression confirmed by radiographic studies. This cage is to be used in patients who have had six weeks of non-operative treatment. The DIVERGENCE™ cage must be used with supplemental fixation. The {2}------------------------------------------------ DIVERGENCE™ cage is also required to be used with autogenous bone graft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and is to be implanted via an open, anterior approach. When used together, the DIVERGENCE™ components can be used only to treat cervical disc disease. ## VIII.
