Slotted Hole Versus Fixed Hole C-Tek

This study's purpose is to compare the fusion rates between the EBI, LLC C-Tek™ Anterior
Cervical Plate, Slotted Hole Design versus the Fixed Hole Design

Inclusion Criteria:

1. Radiographic evidence of compressed cervical roots or cord by either ossified bony
elements or herniated nucleus pulposus.

2. Symptomatic radiculopathy appropriate to compressed nerve root.

3. Cervical spondylosis as evidenced by reactive changes in the vertebral bodies about
the interspace, and may be associated with chronic discopathy.

4. Primary anterior cervical spinal fusion (ACDF) performed using an anterior cervical
plate and either a discectomy (Smith-Robinson technique) or a Corpectomy.

5. Adult male or female, 18 to 75 years of age.

study.

7. The subject will be available for follow-up for a minimum of 24 months.

Exclusion Criteria:

1. Traumatic cervical injury.

2. Posterior augmentation or revision fusion.

3. Cervical fusion involving C1 and C2 vertebrae.

4. Cervical fusion involving more than three levels.

5. Previous spine surgery at the same levels as those that will be fixed with the C-Tek
plate.

6. Systemic conditions: Spondylitis, Paget's disease, Rheumatoid arthritis, Infection
within two weeks before surgery, Cancer, Renal disease or insufficiency with
creatinine level above 2, Chronic use of steroids or other conditions that may affect
