Who benefits?
Discectomy is the most common spine operation and is most effective for leg pain, not back pain. It's recommended for patients with a confirmed lumbar disc herniation and sciatica that:
- Hasn't improved after about six weeks of conservative care, or
- Comes with significant or progressive weakness, or
- Is severe enough to prevent work, sleep or daily function
The procedure
Under general anesthesia, a small incision is made beside the midline of the low back. Sequential dilators gently spread the muscle and a tube is placed directly over the affected level. Using an endoscope or microscope, Dr. Ferachi removes a small window of bone and ligament if needed, protects the nerve, and removes the herniated fragment. The tube is removed and the muscle falls back into place. Surgery typically takes about an hour.
Recovery
- Most patients go home the same day
- Leg pain often improves immediately; numbness may take longer
- Walking is encouraged right away
- Desk work in one to two weeks; lifting restrictions for about six weeks
There is a small risk (roughly 5–10%) of the disc herniating again in the future. Dr. Ferachi will review this and other risks with you.
Common questions
What is the difference between a microdiscectomy and a microendoscopic discectomy?
Both remove the herniated portion of the disc. Microendoscopic discectomy uses a tubular retractor and endoscope or microscope through a smaller incision, minimizing disruption of the back muscles.
Will I need a fusion after a discectomy?
Usually not. Discectomy removes only the herniated fragment and preserves the disc and spinal stability.
