Endoscopic Spine Surgery in West Covina

For West Covina residents who need spine surgery, the most minimally invasive option in modern spine care is available right here in town. Dr. Kambiz Hannani has performed endoscopic spine procedures for more than two decades from his West Covina practice, with surgery done at Emanate Health Queen of the Valley Hospital — also in West Covina. That means a procedure designed to get you home the same day actually does get you home the same day, because home is just a few minutes from the operating room. No two-hour drive across the LA basin while you are still groggy from anesthesia. No coordinating an out-of-town hotel stay for a follow-up. The whole episode of care fits inside your own zip code.

Endoscopic spine surgery is also a procedure where it pays to find a surgeon who actually does it routinely. Many spine surgeons in the San Gabriel Valley still default to open or microsurgical techniques because endoscopic surgery requires specialized training and a meaningful volume of cases to do well. Dr. Hannani has been a local fixture in spine care for West Covina families for over twenty years and offers the full endoscopic spectrum, which is why patients here often choose him over driving into Los Angeles for the same procedure.

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 West Covina Patients Choose Dr. Hannani for Endoscopic Spine Surgery

The biggest reason is the simplest one: he is the local fellowship-trained spine surgeon who actually does these procedures routinely, and his office and surgical site are both in West Covina. The whole point of an endoscopic discectomy is to be back to normal life fast — that promise is a lot more believable when the entire care episode happens within five minutes of your home, rather than after an hour-long drive back from somewhere in Los Angeles in the immediate post-operative period.

There is also the longer arc. Dr. Hannani has been treating West Covina families for over two decades. Many of the patients in his clinic today were referred by a neighbor, a co-worker at the school district, a parent, or someone they sat next to at church. That kind of long-standing local trust is part of why people here choose him for serious procedures — and why the practice has stayed local rather than chasing a flashier address in Los Angeles.

A Patient's Story

A West Covina patient in his late thirties — a long-time city employee who lives near Galster Wilderness Park — came in with classic sciatica that had not let up after eight weeks of physical therapy and an epidural injection. He could barely sit through a full work day. His MRI showed a single L5-S1 disc herniation pressing the S1 nerve. He was a textbook endoscopic discectomy candidate. The procedure took about 45 minutes at Emanate Health across town. He walked within an hour of finishing, was discharged that afternoon, and his wife had him home in less than ten minutes. He was off narcotics within two days and back at his desk inside of two weeks. The total drive distance for his entire surgical episode — pre-op visit, surgery, post-op visits — was less than the round trip he would have made for a single appointment at a downtown LA hospital.

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. The right operation is the one matched to your specific problem.

What Recovery Looks Like

For a typical endoscopic lumbar discectomy at Emanate Health:

• Day of surgery: 30 to 60 minute procedure under sedation or light general anesthesia. Walking within an hour. Discharged home the same day — usually within a 5 to 10 minute drive.

• 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, 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

Where exactly is your office? Our practice is located in West Covina — just minutes from anywhere in the city. For the exact address, parking information, and a map, please visit our contact page.

Where do you perform the surgery? Dr. Hannani's primary surgical site for endoscopic spine procedures is Emanate Health Queen of the Valley Hospital, right here in West Covina. He also has privileges at Emanate Health Inter-Community Hospital in adjacent Covina, and at outpatient surgery centers in the area.

How fast can I get an appointment as a local West Covina patient? Local patients are typically seen within a week, and often sooner for cases with significant pain or weakness. Bring any prior MRI imaging on disc so Dr. Hannani can determine endoscopic candidacy at the first visit.

If endoscopic surgery is so much less invasive, why doesn't every spine surgeon offer it? Because it requires specialized fellowship-level training and a meaningful case volume to do well. Many surgeons trained before endoscopic spine techniques became mainstream and continue to default to microsurgical approaches. That is a perfectly reasonable choice for them — but it is the reason West Covina patients who specifically want an endoscopic approach often seek out Dr. Hannani directly.

Is endoscopic spine surgery covered by insurance? Yes. Endoscopic procedures are billed under standard CPT codes and are covered by most major insurance plans in California, including Medicare, when medical necessity is documented. Our office handles pre-authorization on your behalf.

How do I schedule a consultation? Call our office at 626-939-5900 or visit our contact page. Bring any prior MRI imaging on disc if you have it — this lets Dr. Hannani assess whether you are an endoscopic candidate at the first visit.
