Medtronic has released a new device that promises to make cervical spine fusions less problematic. The PEEK PREVAIL eliminates the need to implant a metal stabilization plate that protects the graft and uses only two screws as anchors.
More about PEEK PREVAIL from the press release:
Biomechanical data suggest that the PEEK PREVAIL Device, with two integrated bone screws, provides construct rigidity similar to that obtained by the traditional fixation techniques of a threaded cage or plating.
Made of polyetheretherketone (PEEK), the new implant is invisible on x-rays, which allows the surgeon to 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 securely in place.
“The specific advantages of the PEEK PREVAIL Cervical Interbody 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 in Melbourne, Florida.
The PEEK PREVAIL Cervical Interbody Device is indicated for use in patients with cervical disc disease from the C2-C3 disc to the C7-T1 disc. Cervical disc disease is defined as intractable radiculopathy (radiating pain) and/or myelopathy (weakness) with herniated disc and/or osteophyte formation on posterior vertebral end plates producing symptomatic nerve root and/or spinal cord compression.
The PEEK PREVAIL Device is to be used with autograft and implanted via an open, anterior approach. This cervical device is to be used in patients who have had six weeks of nonoperative treatment.
