Cervical Disc Replacement

Cervical disc replacement is a surgical procedure that involves replacing a damaged or diseased cervical spinal disc with an artificial disc. It aims to restore the natural function and range of motion of the spine while alleviating pain. Studies report that cervical disc replacement is safe and effective for the treatment of both one-level and two-level cervical degenerative disc disease, and in two-level surgeries, it has been shown to be superior to cervical fusion.

The standard approach to replacing a cervical disc involves removing the disc and fusing the upper and lower vertebrae. However, when two bones that once moved independently are fused, the degeneration of the discs above and below the fusion accelerates. Artificial cervical disc replacement is intended to and restore the properties of a healthy disc to avoid additional stress on adjacent discs caused by fusion.

A good candidate for cervical disc replacement is someone who has ongoing neck pain due to disc disease that negatively affects function and quality of life and who has failed to find relief with six weeks of conservative management.

• Patients with painful cervical degenerative disc disease in a single or two contiguous levels between C3 and C7 lead to pain, stiffness, and reduced mobility.
• Patients with cervical radiculopathy have significant discomfort from a herniated disc or degenerative disc changes that compress a nerve root to cause pain, numbness, and weakness that radiates into the arms and hands.
• Patients whose condition is linked to specific problems with the discs in their neck.
• Patients who have neurological deficits, including changes to reflexes, problems with coordination and gait, and even disturbances in bowel and bladder function.
• Patients must not have severe spinal instability, significant bone disease, or active spinal infections.

Cervical disc replacement surgery is performed under general anesthesia. Dr. Ball will access the spine through an incision on the front of the neck. He will carefully remove the damaged disc and prepare the space for the artificial disc. Dr. Ball will use a specially designed artificial disc that he will insert into the space where the natural disc was located. This disc is meant to mimic the size and function of the natural disc. The incision is closed over a drain with absorbable sutures.

Advances in spinal disc replacement technology have revolutionized spinal surgery, offering patients a motion-preserving alternative to traditional spinal fusion. Unlike fusion, which restricts mobility by permanently joining vertebrae, artificial disc replacements mimic the natural movement of the spine, helping to alleviate pain while maintaining flexibility. Modern disc implants are designed with durable, biocompatible materials and tailored to individual patient anatomy, leading to improved outcomes and faster recovery. These innovations allow patients to experience enhanced quality of life with reduced risk of adjacent segment disease, a common complication of fusion procedures. Here are two innovative technologies Dr. Hieu Ball uses consistently.

prodisc C Total Disc Replacement

The most studied tdr system in the world.

Beginning with clinical usage in 1990, the prodisc design has been validated with over 125,000 device implantations worldwide and more than 540 published papers.

The prodisc C Total Disc Replacement has been determined to be safe and effective in the treatment of intractable symptomatic cervical disc disease (SCDD) at one level from C3 to C7.

The prodisc C Total Disc Replacement surgery is intended to:

• Remove the diseased disc
• Restore normal disc height
• Decompress surrounding neural structures
• Potentially provide motion in affected vertebral segment
• Improve patient function

Mobi-C Total Disc Replacement

Mobi-C Cervical Disc, an artificial disc implant designed to replace damaged cervical discs in the neck. Unlike traditional spinal fusion, which limits motion by permanently joining vertebrae, the Mobi-C disc aims to preserve natural neck movement. It consists of two metal plates and a polyethylene insert that allows for sliding and rotation, facilitating self-adjustment to cervical spine movements. Notably, the Mobi-C was the first cervical disc approved by the U.S. Food and Drug Administration (FDA) for both one- and two-level disc replacements, offering a motion-preserving alternative to fusion for patients with cervical disc degeneration or herniation.
