What We Treat & How We Do It

ADVANCED
SURGICAL
TECHNIQUES

Dr. Okumu combines the most advanced surgical technologies available with unparalleled precision — giving patients smaller scars, less pain, and faster returns to the activities they love.

Minimally Invasive Spine Surgery

Traditional open-back surgery requires large incisions and weeks of recovery. Our MIS techniques use pencil-sized portals to access the spine — dramatically reducing muscle disruption, blood loss, and hospital time.

Disc Herniation & Nerve Compression
Spinal Stenosis
Lumbar & Cervical Fusion
Spondylolisthesis
Artificial Cervical Disc Replacement

Endoscopic Spine Surgery

The most advanced form of minimally invasive surgery available. Using a 7mm endoscope and HD camera, Dr. Okumu operates through an incision smaller than a fingernail — with real-time visualization and precision unmatched by traditional methods.

Endoscopic Discectomy
Endoscopic Foraminotomy
Endoscopic Laminectomy
Outpatient Same-Day Discharge

Robotic Spine Surgery

Robotic guidance systems give Dr. Okumu sub-millimeter accuracy during implant placement and spinal fusion — far exceeding what the human hand alone can achieve. The result: more precise surgery, fewer complications, faster recovery.

Robotic-Assisted Fusion
Pedicle Screw Placement
Complex Deformity Correction
Revision Spine Surgery

Robotic Joint Replacement

Robotic-arm assisted total joint replacement delivers a personalized surgical plan for each patient's unique anatomy. Expect dramatically improved implant positioning, better long-term outcomes, and a faster path back to running, hiking, and cycling.

Patient Stories

WHAT OUR PATIENTS SAY

★★★★★

I had endoscopic surgery with Dr. Okumu for a herniated disc and was back on my road bike in three weeks. I expected months of recovery. The tiny incision healed faster than I expected. He genuinely changed my life.

Cyclist · Palo Alto, CA
★★★★★

As a 42-year-old runner, I was terrified of spine surgery. Dr. Okumu explained every option clearly, recommended the least invasive approach, and I ran a half marathon 4 months later. Cannot recommend him highly enough.

JL
Jennifer L.
Runner · Mountain View, CA
★★★★★

Robotic knee replacement with Dr. Okumu was a completely different experience than what I expected. Back to hiking within 6 weeks. The technology he uses is genuinely remarkable — and so is his bedside manner.

Frequently Asked Questions

YOUR QUESTIONS
ANSWERED

Common questions about minimally invasive spine surgery, endoscopic procedures, robotic surgery, and what to expect at the Silicon Valley Spine Center.

Minimally invasive spine surgery (MIS) uses small incisions — often less than an inch — and specialized instruments rather than the large cuts required in traditional open surgery. This approach causes far less disruption to the surrounding muscles and soft tissues, resulting in significantly less post-operative pain, reduced blood loss, shorter hospital stays, and dramatically faster recovery times. Most MIS patients go home the same day or next day, compared to multiple days in the hospital for open procedures.
Endoscopic spine surgery is the most advanced form of minimally invasive spine surgery. Dr. Okumu works through an incision of approximately 7–8mm using a high-definition camera (endoscope), allowing him to see and treat the source of your pain with extraordinary precision. Ideal candidates include patients with herniated discs, spinal stenosis, sciatica, pinched nerves, and foraminal stenosis. Many patients who were told they need traditional open surgery are in fact excellent candidates for endoscopic approaches. A consultation with Dr. Okumu will determine the best approach for your specific anatomy and condition.
No — Dr. Okumu performs every surgery himself. The robotic system acts as an intelligent guidance platform, helping him execute the pre-planned surgical steps with sub-millimeter precision. Before surgery, advanced imaging is used to create a 3D map of your unique anatomy. During surgery, the robotic arm guides instruments along the exact pre-planned path — eliminating the small variations that occur even in the most skilled hands. This means more accurately placed implants, reduced risk of complications, and better long-term outcomes.
Recovery timelines vary depending on the procedure and individual factors, but minimally invasive and endoscopic approaches consistently allow much faster return to activity than traditional surgery. Many endoscopic patients resume light exercise within 1–2 weeks and sports within 4–8 weeks. Robotic-assisted fusion patients typically return to low-impact activity within 6–12 weeks. During your consultation, Dr. Okumu will give you a personalized recovery timeline based on your specific procedure, fitness level, and goals.
The Silicon Valley Spine Center accepts most major insurance plans including PPO plans from Anthem, Blue Shield, Aetna, Cigna, UnitedHealthcare, and many others. We also work with Medicare and select HMO plans. Our insurance coordinator will verify your specific benefits and coverage prior to your first appointment. Please call our office at (408) 583-4699 or list your insurance when requesting an appointment online and we will confirm coverage promptly.
Absolutely. A second opinion with a surgeon who specializes in the most advanced minimally invasive and endoscopic techniques can be genuinely transformative. Many patients who arrive with plans for traditional open surgery discover they are excellent candidates for endoscopic or robotic procedures — meaning less pain, smaller incisions, and faster recovery. Dr. Okumu welcomes second-opinion consultations and will provide an honest, thorough assessment of your imaging and symptoms.
