Microdiscectomy

Microdiscectomy is a minimally invasive surgery that removes the portion of a herniated disc pressing on a spinal nerve. It is one of the most common spine surgeries and is primarily used to relieve leg pain (sciatica) caused by a lumbar disc herniation. The small incision and focused approach typically allow a quick initial recovery.

What to expect

  • Performed under general anesthesia through a small incision, often with a microscope or tubular retractor.
  • Surgery typically takes about one hour and is often outpatient or a one-night stay.
  • Leg pain relief is often noticeable soon after surgery, though numbness can take longer to fade.
  • Walking begins the same day; desk work often resumes within one to two weeks.
  • Bending and heavy lifting are typically restricted for several weeks; full recovery commonly takes six to twelve weeks.

Common questions

How fast is recovery after microdiscectomy?
Many people walk the same day and return to desk work within one to two weeks. Full recovery, including lifting and sports, commonly takes six to twelve weeks with your surgeon's clearance.
Can the disc herniate again?
Yes, a re-herniation at the same level is possible in a minority of patients. Following lifting restrictions and building core strength in recovery may help lower the risk; your surgeon will advise.
Do herniated discs always need surgery?
No, most improve over weeks to months with non-surgical care such as physical therapy and medication. Surgery is typically considered for persistent severe pain, progressive weakness, or symptoms that fail conservative treatment.
