Intended Use

Properly used, this system is intended for anterior interbody screw/plate fixation of the cervical spine. The indications and contraindications of spinal instrumentation systems should be well understood by the surgeon. The system is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with: 1) 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, lordosis, or scoliosis), 5) pseudarthrosis, and/or 6) failed previous fusions. Nota Bene: This device system is intended for anterior cervical intervertebral body fusions only. WARNING: This device is not approved for screw attachment to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

Device Story

Zephir Anterior Cervical System comprises bone plates and screws for anterior interbody fixation; provides temporary stabilization during cervical spinal fusion. Features pre-assembled anti-migration caps covering screw heads to prevent back-out. Used by surgeons in clinical settings; implanted via anterior approach to cervical spine. System provides mechanical support to vertebral bodies; facilitates fusion process. Benefits patients by stabilizing spine during healing; reduces risk of screw migration.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

System consists of bone plates and screws with integrated anti-migration caps. Mechanical fixation device; no energy source or software components.

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 element (pedicle) attachment.

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.

# ZephirTM Anterior Cervical System 510(k) Summary January 2003

FEB 2 6 2003

- Medtronic Sofamor Danek I. Company: 1800 Pvramid Place Memphis, TN 38132 [phone]
#### Proprietary Trade Name: Zephir™ Anterior Cervical System II.

#### Regulation Number: 888.3060 - KWQ III.

#### IV. Product Description

The ZEPHIR™ Anterior Cervical System consists of a variety of bone plates and screws. Fixation is achieved by inserting bone screws through the openings in the plate into the vertebral bodies of the cervical spine. The ZEPHIR™ Plates include anti-migration caps that cover the heads of the bone screws to reduce the potential for screw back-out. The anti-migration caps come pre-assembled to the plate.

The purpose of this submission is to add additional screws to the Zephir™ Anterior

Cervical System.

#### V. Indications

Properly used, this system is intended for anterior interbody screw/plate fixation of the cervical spine. The indications and contraindications of spinal instrumentation systems should be well understood by the surgeon. The system is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with: 1) 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, lordosis, or scoliosis), 5) pseudarthrosis, and/or 6) failed previous fusions.

Nota Bene: This device system is intended for anterior cervical intervertebral body fusions only.

WARNING: This device is not approved for screw attachment to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

### Substantial Equivalence VI.
