New Cervical Interbody Device for Neck Surgery

An innovative cervical interbody device (CID) with two integrated bone screws provides construct rigidity similar to that obtained by traditional fixation techniques, such as a threaded cage or a graft with plating.

The PEEK Prevail CID is indicated for use in patients with cervical disc disease from the C2-C3 disc to the C7-T1 disc, who have had six weeks of nonoperative treatment. The new spinal implant, which is made of polyetheretherketone (PEEK), is invisible on X-rays, allowing the surgeon to view the spinal fusion during a follow-up visit. Featuring an "I-beam” shape with a two-screw configuration, the device is intended to be used with autograft and implanted via an open, anterior approach.


The zero-profile device eliminates the need for a plate and attaches to the spine using only two screws, and incorporates a Nitinol wire locking mechanism to keep the screws securely in place. The PEEK Prevail cervical interbody device is a product of Medtronic (Minneapolis, MN, USA), and has received the European Community (CE) marking of approval.

"With the PEEK Prevail cage, you can achieve a solid fusion. When using this cage additional plating is not necessary. As this cage is easy to implant, surgery time and traction on the esophagus is significantly reduced. I believe this is a safe and reliable cervical cage, which may contribute to a better outcome for our patients,” said Eric Put, MD, a neurosurgeon at the Jessa Hospital (Hasselt, Belgium).

An interbody fusion device is a prosthesis used in spinal fusion procedures to maintain foraminal height and decompression. Once placed, the cages resist flexion and extension of the spine, and axial forces across the ventral and middle columns.
