Medtronic launches two new orthopedic devices.

Medtronic's Spinal and Biologics division, based in Memphis, Tenn., has launched two orthopedic devices, the PEEK Prevail cervical interbody device and the Vertex Select Reconstruction System Occipitocervical Module.

Cervical Interbody Device Eliminates Need for Plate

PEEK PREVAIL is an implant used to treat patients who suffer from cervical disc disease. It is designed to provide stability during spinal fusion and eliminates the need for a plate. It attaches to the spine using two screws, according to the medical device giant.

Made of polyetheretherketone (PEEK), the implant is virtually invisible on X-rays, which lets the surgeon view the spinal fusion during a follow-up visit. Featuring an "I-beam" shape with a two-screw configuration, the device incorporates a Nitinol wire locking mechanism to keep the screws in place, company officials said.

"The specific advantages of the PEEK Prevail cervical inter-body device over other techniques--such as zero profile and device design--makes this an exciting option for today's spinal surgeon," said Dr. Richard A. Hynes, president and medical director of the B.A.C.K. Center, an orthopedic practice in Melbourne, Fla.

The PEEK Prevail is ideal for patients with cervical disc disease affecting the C2-C3 disc to the C7-T1 disc and who have had six weeks of nonoperative treatment, according to Medtronic.

Occipitocervical Module Offers Spinal Fusion Options

The Vertex Select reconstruction system occipitocervical module contains implants and an instrument set necessary for performing surgery where the base of the skull (occiput) has to be fused to the neck (cervical-upper thoracic spine). This procedure must be performed from the back of the spine (called the posterior approach). To treat instability caused by conditions of the spine, such as degenerative disease, surgeons perform a spinal fusion, which involves joining two bones together, such as the occiput and vertebrae.

Used with the existing Vertex reconstruction system, the Vertex Select occipitocervical module offers adjustability through multiple plate designs, rods, screws and hooks that give surgeons more options during surgery.

"The flexibility of the Vertex Select reconstruction system helps overcome challenges of occipitocervical fusion," said Dr. Vincent Traynelis, neurosurgeon at Rush University Medical Center in Chicago, Ill.
