Cervical Arthroplasty (Artificial Disc Replacement)

What is Cervical Arthroplasty?

Cervical arthroplasty, or artificial disc replacement, is a surgical procedure to relieve neck pain and nerve compression caused by a damaged cervical disc. Instead of fusing the vertebrae, an artificial disc is inserted to maintain natural motion in the cervical spine. The procedure is performed through a small incision in the front of the neck, where the damaged disc is replaced with a prosthetic designed to mimic the function and movement of a natural disc.

Conditions Treated with Cervical Arthroplasty:

  1. Herniated Disc: When a cervical disc bulges or ruptures, it can press on nerves, causing neck and arm pain. Replacing the damaged disc with an artificial one helps relieve pressure and restore movement.
  2. Cervical Degenerative Disc Disease: Age-related disc degeneration can cause pain and stiffness. Arthroplasty helps relieve pain without compromising neck mobility.

When is cervical arthroplasty recommended?

Cervical arthroplasty is typically recommended for patients suffering from cervical radiculopathy or myelopathy due to disc degeneration or herniation. Patients who have not responded to conservative treatments, such as physical therapy or medication, may benefit from this procedure. Additionally, suitable candidates are often those looking to maintain mobility in the cervical spine.

How is the procedure performed?

The procedure begins with the surgeon making a small incision at the front of the neck to access the cervical spine. The damaged disc is carefully removed, and the artificial disc is inserted into the disc space. This prosthetic disc is designed to mimic the natural disc's movement, allowing the patient to maintain a range of motion while providing the necessary support to the spine.

FAQ

1. How long is the recovery after cervical arthroplasty?

Recovery typically takes several weeks, with most patients returning to normal activities in 4 to 6 weeks.

2. Will I need physical therapy?

Physical therapy may be recommended to strengthen neck muscles and enhance recovery. Dr Harrington will discuss this based on your needs.

3. What are the benefits of arthroplasty over fusion?

Arthroplasty preserves neck motion, while fusion restricts movement. This can prevent additional wear on adjacent discs over time.

4. Will it take long to recuperate fully?

The recovery time following cervical arthroplasty varies depending on the individual patient and the complexity of the surgery. However, most patients can expect the following general timeline:

  • Immediate Post-Operative Period (0-2 weeks):

    Patients typically stay in the hospital for 1-2 days following surgery.
    Pain and discomfort are common but manageable with prescribed medications.
    Light activities, such as walking, are encouraged soon after surgery to promote healing.

  • Early Recovery (2-6 weeks):

    Most patients can return to light activities, within 1-2 weeks.

    Avoid heavy lifting, strenuous activity, and excessive neck movements during this time.

  • Full Recovery (6 weeks to 3 months):
    By 6 weeks, patients can typically resume moderate physical activity, including low-impact exercise.

    Most patients return to normal activities, including driving, and work that does not involve extensive physical strain.

    Full recovery, including a return to more physically demanding activities, generally occurs by 3 months.

The recovery process may vary depending on factors such as the patient’s overall health, activity level, and adherence to post-operative guidelines provided by their treating team. Physical therapy may also be recommended to aid in recovery and restore strength and range of motion.

5. What are the potential risks?

  • While cervical arthroplasty is generally considered a safe procedure, like any surgery, it carries some potential complications. These include:
  • Infection: Though rare, infections at the surgical site can occur and may require antibiotic treatment or additional surgery.
  • Implant Complications: The artificial disc may shift, loosen, or wear over time, potentially requiring revision surgery.
  • Nerve Injury: There is a risk of nerve damage during surgery, which could lead to temporary or permanent issues such as weakness, numbness, or pain in the arms or hands.
  • Spinal Cord Injury: Though uncommon, there is a risk of injury to the spinal cord, which could result in serious neurological issues.
  • Dysphagia (Difficulty Swallowing): Some patients may experience temporary difficulty swallowing after surgery.
  • Hematoma: A collection of blood near the surgical site may occur, potentially compressing nearby structures and requiring further intervention.
  • Adjacent Segment Degeneration: Over time, discs adjacent to the replaced one may degenerate, leading to new symptoms or the need for additional surgery.

Although complications are infrequent, patients should discuss the risks with their surgeon before the procedure.

6. What should I avoid after the procedure?

  • Avoid strenuous activities
  • Avoid driving for a specified time after the procedure
  • Smoking and Nicotine Use: Smoking can impair bone healing and fusion, so it is important to avoid tobacco and nicotine products.
