Cervical Disc Replacement in Los Angeles

Cervical disc replacement, also called cervical artificial disc replacement (ADR), is a motion-preserving surgery that removes a damaged or herniated disc in the neck and replaces it with an artificial disc. The goal is to relieve pressure on the spinal cord or nerves while maintaining motion at the treated level.

Candidates are typically patients with symptomatic cervical degenerative disc disease or a cervical disc herniation causing neck pain, arm pain, numbness, weakness, radiculopathy, or spinal cord compression that has not improved with appropriate nonoperative treatment. Candidacy depends on factors such as the location of the disease, spinal alignment and stability, facet joint health, bone quality, and the degree of degeneration.

Cervical disc replacement is designed to preserve motion at the treated level. Anterior cervical discectomy and fusion (ACDF) removes the damaged disc and permanently joins the adjacent vertebrae. Disc replacement may be an alternative to fusion in appropriately selected patients, while ACDF may be more appropriate when significant instability, deformity, poor bone quality, advanced facet arthritis, or other contraindications to disc replacement are present.

Neither cervical disc replacement nor ACDF is the best option for every patient. Cervical disc replacement may offer advantages in appropriately selected patients, including preservation of motion at the treated level and avoidance of fusion. The most appropriate procedure depends on the patient's diagnosis, anatomy, spinal stability, facet joints, number of affected levels, and treatment goals.

Yes. Two-level cervical disc replacement may be performed in appropriately selected patients with symptomatic disease involving two adjacent cervical discs. Certain FDA-approved artificial cervical discs are indicated for treatment at two contiguous levels. Eligibility depends on the specific levels involved, implant indications, anatomy, spinal stability, facet joint condition, and bone quality.

Cervical disc replacement is commonly used to treat cervical degenerative disc disease, cervical disc herniation, cervical radiculopathy, and certain cases of spinal cord compression or cervical myelopathy caused by disc-level pathology. It is not appropriate for every cause of neck or arm symptoms, making an accurate diagnosis and careful patient selection essential.

Cervical disc replacement is generally performed through a small incision in the front of the neck. The damaged disc and any compressive disc or bone material are removed to relieve pressure on the spinal cord and nerves. The disc space is then restored, and an artificial cervical disc is placed between the vertebrae to preserve motion at the treated level.

Patients are typically encouraged to begin walking shortly after surgery and gradually increase their activity during recovery. Many patients return to light daily activities relatively quickly, while work, exercise, and more strenuous activities are resumed progressively based on healing and the surgeon's recommendations. Recovery varies depending on the number of levels treated, the patient's overall health, and the physical demands of their activities.

Modern artificial cervical discs are designed for long-term implantation, and clinical studies have demonstrated durable outcomes at long-term follow-up. However, no artificial implant can be guaranteed to last indefinitely. Implant longevity may depend on factors such as positioning, anatomy, activity level, bone quality, and the condition of the surrounding cervical spine.

As with any spine surgery, cervical disc replacement has potential risks. These may include infection, bleeding, nerve or spinal cord injury, swallowing difficulty, voice changes, implant migration or wear, heterotopic bone formation, persistent symptoms, and the possibility of additional surgery. An individualized evaluation is necessary to determine whether the potential benefits outweigh the risks.

Yes. Returning to an active lifestyle is often an important goal of cervical disc replacement. Walking usually begins early after surgery, while strengthening, cardiovascular exercise, weight training, and other activities are introduced progressively based on healing and the surgeon's recommendations.

Many appropriately selected patients return to recreational exercise and sports following recovery from cervical disc replacement. The timing and type of activity depend on healing, neurological recovery, conditioning, the number of levels treated, and the physical demands of the sport.

Clinical studies of appropriately selected patients have demonstrated significant improvements in neck pain, arm pain, neurological symptoms, and function following cervical artificial disc replacement, while maintaining motion at the treated level. Individual outcomes vary based on the underlying diagnosis, patient selection, surgical technique, and other medical and spinal factors.

Cervical disc replacement may not be appropriate for patients with conditions such as significant cervical instability, advanced facet joint arthritis, severe osteoporosis, certain spinal deformities, infection, severe spondylosis, or anatomy that does not allow safe placement of an artificial disc. Each patient requires an individualized evaluation to determine whether disc replacement or another treatment is more appropriate.

Insurance coverage for cervical disc replacement varies by insurance carrier, diagnosis, number of levels being treated, implant, and the patient's individual policy. Prior authorization is often required. The surgeon's office can review coverage requirements and help determine whether cervical artificial disc replacement may be covered.

Patients considering cervical disc replacement in Los Angeles should seek evaluation from a spine surgeon experienced in both motion-preserving surgery and cervical fusion. A comprehensive evaluation can determine whether cervical disc replacement, ACDF, hybrid surgery, continued nonoperative treatment, or another treatment option is most appropriate.
