Lumbar Microdiscectomy in New York
Also known as: Microdiskectomy, Lumbar Microdiskectomy, Microscopic Discectomy, Lumbar Disc Surgery, Minimally Invasive Lumbar Discectomy
Dr. Marcus Rivera

More than 1,500 lumbar microdiscectomies performed, but the operating-room number is not the headline. The headline is the conservative-first protocol that runs in front of every one of them: structured rehab, image-guided injections, and a 6-to-12-week observation window before surgery is on the table. Dr. Marcus Rivera operates only when leg pain or weakness persists past that line — and when he does, the microscope-assisted approach decompresses the nerve through a 1- to 2-centimeter incision, with most patients home the same day.
Lumbar microdiscectomy is a minimally invasive spine surgery in which a small portion of a herniated lumbar disc that is pressing on a nerve root is removed using an operating microscope or surgical loupes through a small incision in the lower back. The procedure is most often used to relieve sciatica caused by a herniated disc that has not improved with conservative care. Because the surgeon works through a 1 to 2 centimeter incision and does not need to remove significant bone, joints, ligaments, or muscle, most patients go home the same day or the next morning and experience a relatively quick return to walking and light activity.
At a Glance
- Lumbar microdiscectomy is among the most commonly performed spinal surgeries in the United States and is considered the standard surgical option for most lumbar disc herniations[1]
- Reported successful outcomes for relief of leg pain (sciatica) are achieved in approximately 90 percent of cases at 6 months, declining modestly with longer-term follow-up[2]
- Randomized trials suggest microdiscectomy provides faster relief of sciatica than continued non-operative care, although outcomes between the two groups converge by approximately 1 to 2 years in many patients[5]
Overview
During a lumbar microdiscectomy, the surgeon makes a small midline incision over the affected disc level and uses retractors to gently separate the back muscles rather than cutting through them. A small portion of the lamina (laminotomy) and ligamentum flavum is removed to expose the nerve root and the herniated disc fragment.
Using an operating microscope or magnifying loupes for enhanced visualization, the surgeon gently retracts the nerve root and removes the herniated disc fragment that is compressing it. The remaining disc space is generally not removed, which preserves spinal stability and height. The goal is to take pressure off the nerve, not to fix the disc itself.
Lumbar microdiscectomy is widely considered the standard surgical option for removing most lumbar disc herniations and is among the most commonly performed spine procedures in the United States. Reported success rates for relief of leg pain are high in the first 6 to 12 months, with a smaller proportion of patients experiencing recurrent herniation or new herniation at another level over longer follow-up.
What to Expect During Treatment
- 1Preoperative evaluation, including history, physical examination, and imaging such as MRI to confirm the disc herniation level matches the patient's symptoms
- 2General anesthesia is administered and the patient is positioned prone with the abdomen free
- 3The level of surgery is confirmed under fluoroscopy or with an intraoperative radiograph
- 4A small midline incision is made and tubular or Caspar retractors are placed to expose the lamina
- 5A small laminotomy and partial flavectomy are performed using an operating microscope or surgical loupes
- 6The nerve root is identified and gently retracted, and the compressing disc fragment is removed
- 7The wound is irrigated and closed in layers with absorbable sutures and skin closure
- 8Patients are typically observed in recovery and discharged home the same day or after an overnight stay
How does Lumbar Microdiscectomy work?
- The patient is positioned prone on the operating table with the abdomen free to reduce venous pressure and bleeding in the surgical field. The level of surgery is confirmed with intraoperative fluoroscopy or radiographs.
- A small midline incision, typically 1 to 2 centimeters long, is made over the affected disc level. Tubular retractors or small Caspar retractors are introduced to gently separate the paraspinal muscles rather than cutting through them.
- Using an operating microscope or surgical loupes for magnification, the surgeon performs a small laminotomy to expose the lateral edge of the spinal canal. The ligamentum flavum is opened and the nerve root and dural sac are identified.
- The compressed nerve root is gently retracted and the herniated disc fragment that is pressing on it is removed using small pituitary rongeurs. The disc space itself is typically not entered widely; the goal is to decompress the nerve, preserve the remaining disc, and minimize the risk of recurrent herniation.
- The wound is irrigated, hemostasis is achieved, and the small layered incision is closed with absorbable sutures and skin closure. A sterile dressing is applied.
When It's Recommended
- Lumbar disc herniation with leg pain (sciatica) that has not responded to at least 6 to 12 weeks of conservative care
- Progressive neurologic deficit such as worsening weakness or numbness in the leg
- Cauda equina syndrome with bowel or bladder dysfunction (urgent surgical indication)
- Severe, intractable radicular pain interfering with sleep, work, or daily function
- MRI findings of a disc herniation that correlate with the patient's symptoms and physical exam

Conditions We Treat
Recovery & Aftercare
- Most patients go home the same day or the morning after surgery, with leg pain often improved immediately or within the first few days
- Walking is encouraged starting the day of surgery; short, frequent walks help reduce the risk of blood clots and stiffness
- Bending, lifting more than approximately 10 pounds, and prolonged sitting are typically limited for 2 to 6 weeks depending on surgeon protocol
- Return to desk work is often possible within 1 to 2 weeks; return to heavy physical work or contact sports generally takes 6 to 12 weeks
- Physical therapy is commonly started 2 to 6 weeks after surgery to restore core strength, mobility, and safe lifting mechanics
- Most patients experience continued gradual improvement over the first 3 months following surgery
- Persistent or worsening symptoms such as fever, drainage from the incision, new weakness, loss of bowel or bladder control, or severe new pain warrant prompt medical evaluation
Alternative Treatments
- Structured physical therapy focused on core strengthening, lumbar stabilization, and nerve gliding exercises
- Activity modification, including avoidance of heavy lifting and prolonged sitting
- Nonsteroidal anti-inflammatory medications, neuropathic pain medications, and short courses of oral steroids in selected cases
- Image-guided epidural steroid injections to reduce nerve root inflammation
- Continued non-operative care, particularly when imaging and symptoms do not strongly correlate
- Endoscopic discectomy or other minimally invasive variations in appropriately selected cases
