A microdiscectomy is a minimally invasive spine surgery that removes the portion of a herniated lumbar disc pressing on a spinal nerve root. This precise procedure relieves pressure on the affected nerve, helping reduce leg pain, numbness, tingling, and weakness – symptoms commonly associated with sciatica (lumbar radiculopathy).
At Midwest Spine & Brain Institute, our board-certified spine surgeons specialize in advanced microdiscectomy techniques that deliver long-term pain relief with minimal tissue disruption and faster recovery. Explore all spine conditions and treatments to learn more about available options.
What Is a Microdiscectomy?
Microdiscectomy (also known as microdecompression) is performed through a small incision in the lower back. Using microscopic visualization and specialized surgical instruments, the surgeon carefully removes the herniated portion of the disc that is compressing the nerve.
Unlike traditional open surgery, this minimally invasive approach allows for:
- Smaller incisions
- Less muscle damage
- Reduced blood loss
- Shorter hospital stays
- Faster recovery
Conditions Treated with Microdiscectomy
Microdiscectomy is often recommended for patients who have not found relief through conservative treatments such as physical therapy, medications, or injections. Common conditions include:
- Lumbar herniated disc
- Sciatica (lumbar radiculopathy)
- Degenerative disc disease with nerve compression
- Recurrent disc herniation
- Spinal nerve compression causing leg weakness or numbness
Microdiscectomy may also be considered for certain cases of spinal stenosis causing nerve compression. In some cases, artificial disc replacement may be considered as an alternative to microdiscectomy or fusion.
Benefits of Microdiscectomy Surgery
Patients who undergo microdiscectomy at Midwest Spine & Brain Institute often experience:
- Immediate or rapid pain relief
- Restoration of leg strength and mobility
- Quicker return to normal activity
- Reduced need for long-term pain medication
- Smaller incision and less postoperative discomfort
What to Expect During and After Surgery
- Anesthesia: The patient is placed under general anesthesia.
- Minimally Invasive Access: A small incision (1–2 inches) is made in the lower back.
- Microscopic Precision: The surgeon uses an operating microscope to locate and remove the herniated disc fragment.
- Recovery: Many patients go home the same day or after an overnight stay.
Recovery Timeline
- Return to light activity: 2–4 weeks
- Full recovery: 6–12 weeks (depending on overall health and occupation)
- Physical therapy: Often recommended to restore flexibility and strengthen back muscles
Microdiscectomy vs. Laminectomy
While both procedures relieve nerve compression, microdiscectomy focuses on removing disc fragments, whereas laminectomy removes part of the vertebral bone (lamina) to widen the spinal canal. Your surgeon will determine the best approach based on your MRI findings and symptoms.

Frequently Asked Questions About Microdiscectomy
Q: How do I know if I need a microdiscectomy?
A: You may be a candidate if you have persistent leg pain, numbness, or weakness from a herniated disc that has not improved after 6–8 weeks of non-surgical treatment.
Q: Is microdiscectomy considered major surgery?
A: No, it’s a minimally invasive procedure. Most patients go home the same day and experience less pain and faster recovery than with traditional surgery.
Q: What is the success rate of microdiscectomy?
A: Studies show microdiscectomy relieves sciatica symptoms in over 90% of patients, especially when performed by experienced spine surgeons.
Q: Can a herniated disc come back after surgery?
A: Re-herniation is rare but possible. Following your surgeon’s post-op instructions and physical therapy plan helps minimize this risk.
