Minimally Invasive Spine Surgery in NJ

Minimally invasive spine surgery (MISS) has revolutionized the treatment of spinal conditions, offering patients smaller incisions, less pain, and dramatically faster recovery compared to traditional open surgery. At Awake Spinal Fusion in Edison, NJ, Dr. Alok Sharan, MD, MHCDS is a nationally recognized leader in minimally invasive spine surgery and a pioneer of awake spine surgery — performing complex spinal procedures while patients remain awake.

What Is Minimally Invasive Spine Surgery?

Traditional open spine surgery requires large incisions (often 5-6 inches or more), extensive muscle dissection, and significant tissue disruption to access the spine. Minimally invasive spine surgery achieves the same surgical goals through incisions typically less than 1 inch, using specialized instruments, tubular retractors, and real-time imaging guidance.

Instead of cutting through muscles, Dr. Sharan uses a tubular retractor system that gently dilates the muscle fibers apart, creating a working channel to the spine without cutting the muscles. This preserves muscle integrity and is the key to faster recovery.

Benefits of Minimally Invasive Spine Surgery

Smaller incisions: Typically less than 1 inch vs. 5-6+ inches for open surgery
Less muscle damage: Muscles are dilated, not cut
Less blood loss: Significantly reduced compared to open procedures
Less post-operative pain: Less tissue trauma means less pain
Shorter hospital stays: Many procedures are same-day or one-night stay
Faster recovery: Return to activities weeks sooner than open surgery
Lower infection risk: Smaller wounds have lower infection rates
Less scarring: Tiny incisions heal with minimal scarring
Better cosmetic results: Small scars vs. large surgical scars

Conditions Treated with Minimally Invasive Surgery

Herniated discs — cervical and lumbar
Spinal stenosis — central and foraminal
Degenerative disc disease
Scoliosis — select adult cases
Sciatica and pinched nerves
Spondylolisthesis — vertebral slippage
Spinal fractures — compression and burst fractures
Spinal tumors — select cases
Spinal infections
Failed back surgery syndrome — revision surgeries

Minimally Invasive Procedures We Offer

Microdiscectomy

The most common minimally invasive spine procedure. Through an incision less than 1 inch, Dr. Sharan removes the herniated portion of a disc that’s compressing a nerve. Success rate exceeds 90%, and most patients go home the same day with immediate leg pain relief.

Minimally Invasive Laminectomy

A laminectomy performed through small incisions to relieve spinal stenosis. Bone and thickened ligament compressing the spinal nerves are removed, creating more space in the spinal canal.

Minimally Invasive Lumbar Fusion (MIS-TLIF)

A lumbar fusion performed through small incisions using tubular retractors. The damaged disc is removed and replaced with a cage and bone graft, then stabilized with screws and rods — all through incisions of about 1 inch each. Patients typically go home the same day or next morning.

Minimally Invasive ACDF

Anterior cervical discectomy and fusion for cervical disc herniations and stenosis. Performed through a small incision in the front of the neck.

Minimally Invasive Cervical Disc Replacement

For select patients, the damaged cervical disc can be replaced with an artificial disc that preserves motion, performed through a minimally invasive approach.

Lateral Lumbar Interbody Fusion (LLIF/XLIF)

Accesses the lumbar spine through the side of the body, avoiding the back muscles entirely. Excellent for multi-level degenerative disease.

Awake Spine Surgery — The Next Evolution

Dr. Sharan has taken minimally invasive surgery to the next level with awake spine surgery. Using local anesthesia and light sedation instead of general anesthesia, patients remain conscious during the procedure.

Why Awake?

Eliminates general anesthesia risks: No intubation, no breathing tube, no nausea — ideal for patients with health conditions that make general anesthesia risky
Real-time patient feedback: The patient can communicate with Dr. Sharan during surgery, providing immediate feedback on symptom resolution
Faster discharge: Without general anesthesia recovery, patients often leave within hours
Better outcomes: Published studies show awake spine surgery achieves equivalent or better outcomes with fewer complications
Cost savings: Reduced anesthesia costs and shorter facility time

Advanced Technology

Dr. Sharan uses state-of-the-art technology to ensure precision and safety:

Intraoperative navigation: Real-time 3D guidance for screw and implant placement
Microscopic and endoscopic visualization: Magnified views for precision
Intraoperative fluoroscopy: Real-time X-ray imaging
Neuromonitoring: Continuous monitoring of nerve function during surgery

Recovery After Minimally Invasive Spine Surgery

Day of surgery: Walking within hours; many patients go home the same day
Week 1-2: Light walking, gentle movements; managing surgical site care
Week 2-4: Gradual increase in activity; return to desk work
Week 4-6: Physical therapy begins; more normal daily activities
Week 6-12: Progressive return to exercise and full activities

Frequently Asked Questions

Is minimally invasive spine surgery as effective as open surgery?

Yes. Multiple studies have shown that minimally invasive techniques achieve the same surgical outcomes as open surgery, with the added benefits of less pain, faster recovery, and fewer complications.

How small are the incisions?

Most minimally invasive spine incisions are between 0.5 and 1.5 inches, compared to 5-6+ inches for traditional open surgery. Some procedures can be performed through incisions as small as a few millimeters.

Will I be awake during surgery?

It depends on the procedure and your preference. Dr. Sharan offers both awake (local anesthesia with sedation) and traditional (general anesthesia) options. He will discuss which approach is best for your specific case.

How soon can I go back to work?

Desk workers typically return within 1-3 weeks. Physical laborers may need 4-8 weeks. Dr. Sharan will provide specific guidelines based on your procedure and job requirements.

Does insurance cover minimally invasive spine surgery?

Yes. Minimally invasive spine surgery is covered by most insurance plans, including Medicare. Our office will verify your coverage before your procedure.
