Minimally Invasive Microdiscectomy

A minimally invasive microdiscectomy may be recommended for patients who:

• Have a herniated lumbar disc causing significant nerve compression.

• Experience sciatica or leg pain that is more bothersome than back pain.

• Have numbness, tingling, or weakness in the leg or foot due to the pinched nerve.

• Do not improve after nonsurgical treatments such as medications, physical therapy, or injections.

• In urgent cases, have progressive weakness or sudden changes in bladder or bowel function.

Dr. B performs the procedure through a small, nickel-sized incision in the back. A narrow (18 millimeter) tubular retractor is placed, allowing surgical instruments to reach the herniated disc while limiting muscle disruption. Unlike traditional open surgery, this approach avoids cutting through the muscles. Using specialized tools, Dr. B carefully removes the portion of the disc pressing on the nerve. Most patients are able to return home the same day of surgery

The advantages of a minimally invasive microdiscectomy include:

• Smaller incision – usually about the size of a nickel.

• Less muscle and tissue disruption compared to open surgery.

• Reduced blood loss during the procedure.

• Lower risk of postoperative pain and less need for narcotic pain medication.

• Faster recovery – patients can often walk the same day and return home the same day of surgery.

• Shorter downtime – many return to normal activities sooner than with traditional surgery.

• Comparable outcomes to open surgery in relieving leg pain and improving function.
