MICRODISKECTOMY
Microdiskectomy is a minimally invasive approach for the removal of a disc herniation using microsurgical techniques, such as a microscope. The procedure is commonly used for the treatment of leg pain (or “sciatica”) caused by impingement of a nerve root from a disc herniation.
Surgical procedure
On the day of the procedure, you will be taken to the operating room and given
anesthesia. Once asleep, the surgeon will make a small incision directly over the
herniated disc using x-ray guidance. A small portion of bone is removed to facilitate
access to the nerve root. Using a nerve retractor, the spinal cord and nerve root are
gently moved, allowing access to the herniated disc. The herniated disc material is
removed, while the healthy disc material is left intact. Length of surgery is 1 to 1.5 hours.
Pre-operative testing and preparations
Prior to your surgery date, you will be required to undergo routine laboratory
tests, EKG and a chest x-ray. If you are over 50 years of age or have any history of
cardiac or pulmonary problems, you will also be required to have a clearance by a
cardiologist or pulmonologist, respectively. You will also be given information on what
medications, both prescription and over the counter, that need to be discontinued preoperatively
as many can interfere with wound healing and bleeding time.
What to expect after surgery
The procedure is done on an outpatient basis, therefore, once you recover from
anesthesia you can be taken home by a friend or family member. You will be given a
prescription for oral pain medication which you may take as directed. Most patients
notice relief of leg pain almost immediately after surgery, however, it may take weeks or
months for numbness or weakness to improve. You will also be given a prescription for
an antibiotic as well as prednisone. Please let the office know before surgery if you have
any allergies to penicillin. Before your discharge, you will be provided with a list of “do’s and don’ts” and arrangements will be made for home health if necessary.
Once you arrive home
You may shower the day after your surgery, but do not remove the dressing.
No soaking in a bath or hot tub for 4 to 6 weeks.
You must wear your back brace when you are up and walking. You do not need
to wear it in bed.
No driving for 1 to 2 weeks.
No lifting greater than 10 pounds for 4 to 6 weeks.
No bending at the waist or twisting the back.
No prolonged sitting upright (greater than 30 minutes at one time).
Walking in encouraged. As you begin to heal, slowly increase your activity level.
Physical therapy may be necessary and we will inform you if need be.
Maintain a healthy diet, a diet rich in protein is ideal for the healing process.
Drink plenty of fluids.
Typical recovery time is 2 to 4 weeks, however, if your job consists of physical
labor, you should not return to work for 8 to 12 weeks.
