What is Artificial Disc Replacement?
Artificial disc replacement surgery is a procedure where the damaged intervertebral disc is removed and replaced with an artificial implant. The surgery relieves spine pain as well as restores the normal range of motion of the spine.
Indications for Artificial Disc Replacement?
Disc replacement is usually indicated when conservative treatments do not help relieve the following:
- Neck/spine stiffness and pain
- Pain, weakness or numbness of the arms and legs
- Difficulty in walking
Artificial disc replacement is contraindicated in the presence of rheumatoid arthritis, pregnancy, morbid obesity, significant osteoporosis or an active malignancy, insulin-dependent diabetes and allergies to stainless steel.
Artificial Disc Replacement Procedure
The procedure is performed under general anesthesia and is guided with the help of X-ray imaging (fluoroscopy). You will lie face up on the operating table. Your surgeon approaches the cervical spine from the front or side of your neck through a small incision. The important structures in your neck are gently moved to the side to access the cervical spine. The damaged disc along with any loose disc fragments or bone spurs are identified and removed. The artificial disc device is sized and placed in the prepared disc space, restoring its normal height and relieving any pressure over the spinal nerves. The incisions are closed and covered with a dressing.
Postsurgical Care following Artifical Disc Replacement
Following surgery, your neck may be immobilized in a collar. You will need to keep the incision area clean and dry. Refrain from hot tubs, swimming, heavy lifting, driving and smoking. You can initiate physical therapy as directed by your surgeon. Take medications as recommended by your doctor. Arrange for a follow-up appointment with your doctor. You may be able to resume light activities in a week or two, and complete normal activities in six weeks.
The potential risks associated with artificial disc replacement surgery may include infection, bleeding, nerve injury, difficulty breathing or swallowing, change in your voice, leakage of spinal fluid, or a break or loosening of the prosthesis, requiring further surgery. Call your doctor if the incision site shows signs of infection such as pain, redness, swelling, or alteration in the quantity of smell of the drainage, or if you develop fever over 101° F.
The advantages of artificial disc replacement include:
- Maintains normal spine movement
- Lowers the risk of degeneration of adjacent segments
- Does not require bone graft
- Allows early spine motion after surgery
- Faster return to daily activities
