Awake Spinal Fusion in Edison, NJ
Spinal fusion without general anesthesia is the specialty of Dr. Alok Sharan, MD, MHCDS at The Spine and Performance Institute in Edison, NJ. As the pioneer of the awake spinal fusion technique and co-editor of Awake Spine Surgery (Thieme Medical Publishers) — the first medical textbook on the subject — Dr. Sharan has performed hundreds of spinal fusions using regional anesthesia instead of general anesthesia. Patients are comfortable, breathing on their own, and go home the same day. Castle Connolly Top Doctor, NY Magazine Best Doctor, 201 five-star Google reviews, 20+ years of experience.
Years Experience
What Makes Awake Spinal Fusion Different
Regional (spinal or epidural) anesthesia numbs below the waist — no breathing tube
Light IV sedation keeps patients relaxed; most remember little of the procedure
Patient can respond if needed — an added neurological safety layer during fusion
Same-day discharge for most lumbar fusion patients
Recovery 2–4 weeks vs. 6–12 weeks with traditional fusion under general anesthesia
Opioid-sparing — most patients off narcotics within days of surgery
Why General Anesthesia Is a Risk for Spinal Fusion Patients
Spinal fusion is one of the most common major spine surgeries — and traditionally one of the procedures most dependent on general anesthesia. Yet general anesthesia carries significant risks, particularly for the patients who most commonly need fusion surgery: older adults, patients with degenerative disc disease, and those with comorbidities like diabetes, obesity, sleep apnea, or cardiovascular disease.
Known risks of general anesthesia in spinal fusion include post-operative cognitive dysfunction (“brain fog” that can persist weeks or months), respiratory complications from ventilator dependence, prolonged nausea and grogginess, higher post-operative opioid requirements, and longer hospital stays. For elderly patients, the risk of post-operative delirium under general anesthesia is particularly significant.
Regional anesthesia sidesteps these risks entirely. By blocking pain signals from the operative spinal segments without affecting the brain, cardiovascular, or respiratory systems, spinal fusion without general anesthesia allows the body to recover from surgery rather than from both the surgery and the anesthesia simultaneously.
Fusion Procedures Performed Without General Anesthesia
Awake vs. Traditional Spinal Fusion
| Traditional Spinal Fusion | Awake Spinal Fusion — Dr. Sharan |
|---|---|
| General anesthesia, ventilator required | Regional anesthesia — patient breathes independently |
| 1–3 day hospital stay | Same-day discharge in most cases |
| 6–12 week recovery | 2–4 week recovery |
| High post-op opioid use | Opioid-sparing — off narcotics within days |
| Cognitive fog, nausea, respiratory risks | Minimal anesthesia side effects |
| Higher overall cost | Lower cost — most insurance accepted |
Dr. Sharan — The Surgeon Who Wrote the Book on Awake Fusion
Dr. Alok Sharan is not just a practitioner of spinal fusion without general anesthesia — he is one of the surgeons who pioneered and documented it for the global medical community. As co-editor of Awake Spine Surgery (Thieme Medical Publishers, 2026), a 246-page, 22-chapter textbook with 17 procedural videos, he helped establish the clinical protocols now used by surgeons worldwide. Fellowship-trained at NYU Hospital for Joint Diseases and Deputy Editor of Clinical Spine Surgery, with over 100 peer-reviewed publications, Dr. Sharan brings unmatched expertise to every consultation at his Edison, NJ practice.

Frequently Asked Questions
Is spinal fusion without general anesthesia safe?
Yes — multiple peer-reviewed studies confirm that awake spinal fusion achieves equivalent fusion rates and pain relief outcomes compared to fusion under general anesthesia, with a lower complication profile. The ability to communicate with the patient during surgery adds a real-time neurological safety layer that general anesthesia does not provide.
What type of anesthesia is used instead?
Regional anesthesia — typically a spinal or epidural block — numbs the relevant spinal segments completely. This is combined with light IV sedation for comfort. The patient breathes independently throughout, with no breathing tube or ventilator required. The anesthesia team monitors the patient continuously.
Which fusion levels can be done awake?
The most commonly performed awake fusion levels are L4–L5 and L5–S1, which are also the most frequently fused levels in the spine. Multi-level lumbar fusion and advanced techniques like TLIF and ALIF can also be performed without general anesthesia in appropriate candidates. Dr. Sharan evaluates each patient individually.
How do I know if I’m a candidate for awake spinal fusion?
Most patients requiring elective spinal fusion are candidates. The awake approach is especially beneficial for older adults, patients with sleep apnea, obesity, cardiac or pulmonary conditions, or anyone wanting to minimize anesthesia risk and speed recovery.
