Questions Wise Patients Ask Their Doctor Before Cervical Disc Replacement

The disc is a soft cushion-like structure between the individual bones of the spine. In most cases, a disc is quite flexible and allows the spine to bend. Disc replacement is defined as the removal of the damaged spinal disc, followed by insertion of an artificial disc between the vertebrae. The artificial disc mimics the functions of a damaged disc, namely to carry a load and assist in motion. Artificial discs are mostly made from metal- or plastic-like (biopolymer) materials or a combination of both.

Artificial Cervical Disc Replacement is needed when the pain arising due to degenerative disc disease or any other disorder is not relieved through non-invasive methods such as medicines, injections, chiropractic therapy, or physical therapy. The type of artificial disc to be used depends on the cause of your back pain, the severity of the pain, and the comfort or experience of the surgeon. The various indications for disc replacement include:

Degenerative disc disease
Back and leg pain
Degenerative scoliosis
Disc-related back pain
Post-facetectomy syndrome
Failed previous surgery
Unstable spinal stenosis
Isthmic spondylolisthesis
Degenerative spondylolisthesis
Segmental instability

Your surgeon will correlate the results of your investigations with conclusions from your history and physical examination to find out the source of your pain. However, not everyone is a candidate for a disc replacement procedure. Your doctor will determine the best treatment for you based on your medical condition. Disc replacement cannot be performed in patients with osteoporosis because their bones are not strong enough to support the procedure. Also, it is not considered a highly successful procedure for patients aged 50 and above.

Frequently Asked Questions

Q. Why do I need disc replacement surgery?

It is important to talk with your surgeon about the purpose of your surgery and how it is related to the diagnosis of your spinal problem. For example, you must understand why it is recommended - to relieve pain, improve functioning, or improve the symptoms?

Q. Are there any other alternatives to disc replacement surgery?

For most spinal conditions wherein, the pain is not relieved by non-invasive methods, spine surgery is the only option. The type of spine surgery that the doctor decides to conduct may depend on the ailment or the root cause of the pain. The most common alternative to disc replacement is microdiscectomy followed by spinal fusion. Some of the most commonly known alternatives to Disc Replacement are as follows:

Spinal Fusion Surgery: Spinal fusion surgery is a procedure that permanently joins two or more bones in the spine, preventing movement between them. The bones that are joined are called vertebrae. Spinal fusion surgery is performed along with other surgical procedures, such as foraminotomy or laminectomy, and after diskectomy in the neck. It is required if the patient has a vertebral injury or fracture.
IDET or Intradiscal Electrothermal Coagulation: This procedure involves inserting a needle into the lumbar disc space, passing a catheter through the needle, and heating the annulus (the outer layer of the disc space).
Posterior Dynamic Stabilisation: This treatment differs from fusion in that it seeks to preserve spinal motion while also offloading the diseased vertebral disc.
Disc Regeneration: Researchers in cellular and molecular biology are exploring ways to use gene therapy to stimulate disc regeneration and/or to slow or prevent disc degeneration.

Q. What are the benefits of having a disc replacement?

Compared to traditional fusion surgery, it offers several advantages for suitable patients:

Maintained Natural Movement of Spine: The natural motion of the affected vertebrae will be preserved by continued motion at the segment after surgery, which will help patients move better during rehabilitation.
Decreased Pressure on Adjacent Discs: Because the spine maintains a normal range of motion, there is less stress on the adjacent discs, reducing the risk of degeneration.
Shorter Rehabilitation and Recovery Times: Many patients who undergo disc replacement surgery report a quicker rehabilitation and return to normal activities than those who undergo spinal fusion surgery.
Improved Pain Relief: Pain from damaged discs can usually be relieved with disc replacement surgery, thereby restoring normal spinal mechanics.
Improved Long-term Mobility: Long-term mobility should improve significantly, with patients able to maintain a normal pattern of motion at the treated level of their spine.
Lower Incidence of Adjacent Segment Disease: There is reduced incidence of excessive loading of the adjacent vertebrae to the affected level over time as a result of the non-fusion spinal motion.

Q. What are the risks involved in disc replacement procedures?

All surgeries carry some risks of developing certain complications, such as infection, excessive bleeding, and nerve injury. In addition to these, disc replacement can lead to complications such as sensitivity to the artificial disc material, breakage or wear of the disc's components, dislocation of the implant, damage to the vertebra where the disc replacement was performed, or failure to improve after the procedure. Your surgeon will discuss all the risks involved in the procedure.

Q. Can I have an MRI after having an Anterior Cervical Discectomy and Fusion?

MRI or CT scans are performed on people who have undergone a spinal fusion surgery with titanium implants to rule out re-herniation or to aid the physician in understanding the condition post-Cervical Disc Replacement Surgery. Always inform the imaging technician performing the MRI or CT scan that you have undergone spinal replacement.

Q. What is the success rate of Cervical Disc Replacement?

The overall success rate of cervical disc replacement is typically around 85%â€“95%, with most patients experiencing significant relief from nerve pain and improved neck function. Some studies report success rates of about 90â€“92%, especially for common levels such as the C5â€“C6 disc, which is frequently affected by degeneration.

Q. How long will the entire procedure take?

Most artificial disc replacement procedures take about 2 to 3 hours.

Q. How long will it take for me to recover from Cervical Disc Replacement Surgery?

Recovery after cervical disc replacement surgery varies from person to person, but most patients begin to feel improvement within a few days of the procedure. Light daily activities can usually be resumed within one to two weeks, while complete recovery typically takes about four to six weeks. During this period, the doctor may recommend limited neck movements, medications, and physical therapy to support healing. Following the surgeon's post-operative instructions carefully helps ensure proper recovery and restores normal neck mobility.

Q. Will there be any kind of pain after disc replacement, and for how long?

It is normal to experience mild pain, stiffness, or discomfort around the neck or surgical site after disc replacement surgery. This usually improves within a few days to a couple of weeks as the body heals. Pain medications and rest help manage discomfort, and most patients notice significant relief from their original symptoms soon after recovery begins.

Q. How much follow-up will I need after the procedure?

Follow-up visits are important for monitoring healing and ensuring the artificial disc is functioning properly. Patients typically have their first check-up within a few weeks after surgery, followed by additional visits over the next few months. The doctor may recommend imaging tests and physical therapy to support recovery and maintain proper neck mobility.
