The neck, or cervical spine, consists of seven vertebrae (C1-C7). Common pathologies in the anterior (front) cervical spine include, but are not limited to, disc herniation, stenosis, and cervical disc degeneration. Surgical treatment for these pathologies may include anterior cervical discectomy and fusion (ACDF), and cervical disc replacement. The ACDF procedure generally consists of resecting soft-tissue or bone to decompress nerves roots or the spinal cord, followed by stabilization so that long-term healing can occur. In conjunction with spinal decompression, the use of anterior cervical plates, such as the NuVasive® Helix and Gradient Plus® Anterior Cervical Plate systems, and standalone cervical interbody fixation devices, such as the CoRoent® Small Interlock™ system, provide stability and fixation for varying patient anatomies. An alternative procedure to an ACDF is a cervical disc replacement surgery, which aims to stabilize the spine while still allowing motion to occur at the joint instead of fusing the vertebrae together. For that reason, artificial cervical disc replacement devices such as the PCM® Cervical Disc have been developed.

A surgical procedure, performed through the front of the neck, to treat spinal cord or nerve root compression by removing the disc, then stabilizing and fusing one or more vertebrae together into a solid section of bone.
Cervical Disc Replacement
A surgical procedure, performed through the front of the neck, to treat spinal cord or nerve root compression by removing and replacing the degenerated disc. Instead of fusing the vertebrae together (ACDF), a cervical disc replacement aims to stabilize the spine while still allowing motion to occur at the affected level. The PCM Cervical Disc is designed to allow patients to preserve all aspects of motion at the level of surgery, including flexion-extension (nodding up or down), lateral bending (side-to-side bending), and axial rotation (turning your neck).
