Microdiscectomy Spine Surgery – FAQs

Intervertebral discs are located between each backbone (vertebra). When damaged, these discs can put pressure on nerves as they leave the spinal cord. An intervertebral diskectomy is a back surgery that removes all or part of these discs. The procedure is most often done on lumbar discs (located in the lower back). It may also be done on cervical discs in the neck. There are two methods for this surgery:

• Open procedure-A large incision is made.
• Microdiskectomy-Small incisions are made, and the doctor inserts tiny instruments through these incisions.

• Discectomy, intervertebral
• Intervertebral discectomy
• Intervertebral diskectomy
• Microdiscectomy

These discs normally serve as cushions between the bones. The discs can become damaged or dry with age. Injury can also cause a disc to bulge (or herniate). These changes can create pressure on nerves leaving the spine. This can cause pain, numbness, and weakness.

The best time to have this surgery is debatable. This is because-for some patients-having early surgery may not result in less pain or disability. In most cases, surgery is only done after other treatments have failed. Other treatments typically include:

• Rest
• Physical therapy
• Medicines

The goal of surgery is to eliminate pain, weakness, and numbness caused by the disc pressing on a nerve. You may feel relief right away, or it may take months for the nerve root to heal. In some cases, your symptoms may not improve. Your doctor will carefully evaluate you before surgery to determine what the best option is.

Complications are rare, but no procedure is completely free of risk. If you are planning to have intervertebral diskectomy, your doctor will review a list of possible complications, which may include:

• Bleeding
• Infection
• Nerve damage
• Bladder or bowel incontinence
• Leakage of spinal fluid
• Another herniated disk (may happen within the first three months after surgery) Factors that may increase the risk of complications include:
• Chronic conditions (eg, diabetes)
• Prior spine surgeries
• Advanced age
• Smoking

Be sure to discuss these risks with your doctor before the surgery.

Prior to Procedure

Your doctor will likely do the following:

• Physical exam
• Ask about the pain and when it started
• Obtain an MRI scan-a test that uses magnetic waves to make pictures of structures inside the back
• Discography-an imaging test used to detect a herniated disk; involves injecting dye into a disc in the spine and taking an x-ray to determine if there are any leaks Leading up to your procedure:
• Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to one week before the procedure, like:
  • Anti-inflammatory drugs (eg, aspirin)
  • Blood thinners, like clopidogrel (Plavix) or warfarin (Coumadin)
• Arrange to have someone drive you home. Also, arrange for someone to help you at home.
• Eat a light meal the night before the surgery. Do not eat or drink anything after midnight.
• Wear comfortable clothing to the hospital.

Anesthesia

General anesthesia will be used. It will block any pain and keep you asleep during surgery.

This depends on:

• Which method your doctor uses (open or minimally invasive)
• Which procedure you need

For example, the minimally invasive surgery may take longer, but the recovery is faster.

You will have pain while recovering which will be taken care of. Your doctor will give you pain medicine.

This surgery is most commonly done in a hospital setting. It may be possible to go home on the same day of the surgery. If you have a cervical diskectomy, you may have to stay in the hospital for a few days.

Call Your Doctor if:

• Signs of infection, including fever and chills
• Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
• Numbness or tingling
• Pain that you cannot control with the medicines you have been given
• Pain, burning, urgency or frequency of urination, or bleeding in the urine
• Cough, shortness of breath or chest pain
• Loss of bladder or bowel control
