Endoscopic Spine Surgery in Santa Monica, CA

If you live in Santa Monica or anywhere on the Westside and an MRI has shown a herniated disc or a pinched nerve, you have probably been told that surgery means a multi-inch incision, a hospital stay, and weeks of recovery. That has not been true for years — at least not for the right candidates. Endoscopic spine surgery is the most minimally invasive surgical option for many of these problems, and Dr. Kambiz Hannani has been performing endoscopic procedures for over two decades. For Santa Monica patients, the operation can be done at Saint John's Medical Center, right at 21st and Santa Monica Boulevard — meaning same-day discharge, home in your own bed in Santa Monica that evening, and back to a desk job within a week.

Dr. Hannani has held surgical privileges at Saint John's continuously since his Spine Surgery Fellowship there in 2001-2002 under Dr. Rick Delamarter — one of the most respected spine surgeons in the country. That two-decade-plus history at Saint John's matters specifically for endoscopic procedures: the OR teams know his technique, the equipment is set up for it, and the same-day flow is genuinely streamlined. Westside patients who want a minimally invasive approach do not have to leave their own zip code for it.

The reason this matters for Santa Monica patients in particular: the Westside has excellent large institutions, but endoscopic spine surgery is a sub-specialized technique that not every spine surgeon performs routinely. Many surgeons at the major Westside hospitals still default to microdiscectomy or open techniques because that is what they trained on. If your problem can be solved through an 8-millimeter incision instead of a 1-inch one, the difference in recovery is real.

What is Endoscopic Spine Surgery?

Endoscopic spine surgery is a category of ultra-minimally invasive procedures that use a thin tube (endoscope) with a camera and light source to access the spine through a single small puncture — typically 7 to 10 millimeters wide, about the size of a pencil eraser. The surgeon watches the procedure on a high-definition monitor and uses specialized micro-instruments passed through the same tube to do the actual work.

Compared with traditional open spine surgery (which uses a 4 to 6 inch incision and dissects through layers of muscle) or even microsurgery (which uses an operating microscope and a 1 to 2 inch incision), endoscopic surgery causes dramatically less tissue damage. Less tissue damage means less pain after surgery, less blood loss, lower infection risk, and a much faster recovery.

Common Endoscopic Procedures

Not every spine procedure can be done endoscopically — but the list of what can is growing every year. The most common endoscopic procedures Dr. Hannani performs include:

• Endoscopic discectomy — removal of a herniated disc fragment compressing a nerve, in the lumbar (low back) or cervical (neck) spine

• Endoscopic foraminotomy — opening up the bony tunnel where a nerve exits the spine, relieving pinched-nerve pain

• Endoscopic laminotomy / decompression — relieving spinal canal narrowing (stenosis) without a large open laminectomy

• Endoscopic rhizotomy — targeted treatment of facet joint nerves causing chronic back pain

Endoscopic vs. Open vs. Microsurgery: A Real Comparison

A patient with a typical lumbar herniated disc has three reasonable surgical options. Here is the practical difference:

• Open discectomy — 3 to 4 inch incision, muscle dissection, often a hospital stay, 4 to 6 weeks before desk work, 8 to 12 weeks before heavy activity. Largely outdated for routine herniated discs.

• Microdiscectomy — 1 inch incision, less muscle damage, usually outpatient, 1 to 2 weeks before desk work, 4 to 6 weeks before heavy activity. The most common modern option.

• Endoscopic discectomy — 8 millimeter incision, almost no muscle damage, outpatient with same-day discharge, often back to desk work within a week, 3 to 4 weeks before heavy activity. The least invasive option.

For a single-level herniated disc in a healthy patient, the endoscopic approach gives outcomes equivalent to microdiscectomy with meaningfully faster recovery. For more complex spinal problems — multi-level stenosis, instability, prior failed surgery — open or fusion surgery may still be the right answer.

Why Santa Monica Patients Choose Dr. Hannani for Endoscopic Spine Surgery

There are two reasons Westside patients specifically gravitate toward this practice for endoscopic procedures. The first is the Saint John's connection — Dr. Hannani trained there, he has operated there continuously since 2001-2002, and the OR team knows his technique. For an outpatient endoscopic procedure where the entire goal is being home the same day, that institutional familiarity translates into smoother flow and fewer surprises.

The second is fellowship-level depth. Endoscopic spine surgery is a technique that benefits enormously from a surgeon who does it regularly rather than occasionally — and many otherwise excellent Westside spine surgeons still default to microdiscectomy because that is what they trained on. Patients from Santa Monica, Pacific Palisades, Brentwood, Westwood, Mar Vista, Venice, West LA, and Culver City come to Dr. Hannani specifically because he has been performing the full endoscopic spectrum — discectomy, foraminotomy, decompression, and rhizotomy — for over 20 years, and the operation happens at their local hospital.

Where Surgery is Performed for Santa Monica Patients

For Santa Monica and Westside patients, the typical endoscopic flow is straightforward:

• Initial consultation — flexible. Most Westside patients schedule the consult around a Saint John's-coordinated visit; some prefer the West Covina office for a longer first visit. Either works.

• Surgery — performed at Saint John's Medical Center, 21st Street and Santa Monica Boulevard. Endoscopic procedures are designed for same-day discharge, so most patients are home in Santa Monica that same evening.

• Post-op follow-up — coordinated locally. The first post-op visit can usually happen within a short drive of the hospital.

A Patient Story

A 41-year-old tech entrepreneur from Brentwood came in with six weeks of severe right leg pain shooting from his low back down to the outside of his right calf — classic L5 nerve root distribution. MRI showed a sequestered disc fragment at L4-L5 compressing the nerve. He had already failed two epidural steroid injections through another Westside practice and was missing important meetings. He underwent an outpatient endoscopic discectomy at Saint John's on a Wednesday morning, walked out of the hospital that afternoon, was off Norco within 48 hours, and was back at his desk in Brentwood the following Monday. Five days, start to finish, without ever leaving the Westside.

Who is a Candidate for Endoscopic Spine Surgery?

The best candidates generally have:

• A clearly defined, single-level problem (one herniated disc, one pinched nerve, one stenotic level)

• Imaging that matches the symptoms — leg pain in the L5 distribution with an L4-L5 disc herniation, for example

• Failed at least 6 weeks of conservative care (physical therapy, medications, often an injection)

• No significant spinal instability or major deformity

• No history of major prior surgery at the same level (this can sometimes still be done — case-by-case)

Patients who are not endoscopic candidates are not stuck — Dr. Hannani offers the full range of spine procedures, from microdiscectomy and decompression to artificial disc replacement and fusion, all of which can be performed at Saint John's. The right operation is the one matched to your specific problem.

What Recovery Looks Like

For a typical endoscopic lumbar discectomy at Saint John's:

• Day of surgery: 30 to 60 minute procedure under sedation or light general anesthesia. Walking within an hour. Discharged the same day — home in Santa Monica that afternoon.

• Days 1-3: Mild soreness around the small incision. Most patients off narcotics within 48 to 72 hours.

• Week 1-2: Most patients return to a desk job. Driving usually permitted within a week (off narcotics).

• Weeks 3-4: Light exercise, walking on the beach or the Promenade, gradual return to normal activity.

• Weeks 6-12: Return to heavy lifting, sports, and physically demanding work.

Risks of Endoscopic Spine Surgery

No spine surgery is without risk. Endoscopic procedures share the same general risks as any spine surgery — infection, bleeding, nerve injury, dural tear (small leak of spinal fluid), and the possibility that symptoms do not fully resolve. The endoscopic technique generally has lower rates of these complications than open surgery because of the smaller working corridor and reduced tissue damage. The most common technical limitation is that some pathology turns out, intraoperatively, to need a slightly larger approach — Dr. Hannani will discuss this possibility honestly during your consultation.

Frequently Asked Questions from Santa Monica Patients

Where will my surgery be performed? At Saint John's Medical Center in Santa Monica, at 21st Street and Santa Monica Boulevard. Dr. Hannani has held surgical privileges at Saint John's since his fellowship in 2001-2002 and operates there regularly. For an outpatient endoscopic procedure, you will be home in Santa Monica that same afternoon.

Do I have to drive to West Covina to see Dr. Hannani? Not for surgery — that is performed locally at Saint John's. For consultations, the West Covina office is one option (about 35 miles, 45-60 minutes via the 10 East), but most Santa Monica patients schedule the consult around a Saint John's-coordinated visit on the Westside. Mention you are a Westside patient when you call.

Do you take Saint John's network insurance plans? Yes — we accept most major California PPO plans (Blue Shield, Aetna, Cigna, United, Medicare) that are commonly used by Saint John's patients. Endoscopic procedures are billed under standard CPT codes and are covered by most major California insurance plans when medical necessity is documented. Our office handles pre-authorization on your behalf.

How does endoscopic compare to the microdiscectomy I was offered at another Westside practice? Microdiscectomy is an excellent operation and the right answer for many patients. The endoscopic approach uses a smaller incision (about 8 mm vs about 1 inch) and disrupts less muscle, which usually means a faster early recovery. For a single-level herniated disc the long-term outcomes are comparable. Bring your MRI to a consultation and Dr. Hannani will tell you honestly which approach fits your anatomy best.

How do I schedule a consultation? Call our office at 626-939-5900 or visit our contact page. Mention you are a Santa Monica or Westside patient and we will coordinate around a Saint John's-based visit where possible. Bring any prior MRI imaging on disc — this lets Dr. Hannani assess whether you are an endoscopic candidate at the first visit.
