Thread Carpal Tunnel Release in California
Thread Carpal Tunnel Release (TCTR) is an incisionless, ultrasound-guided procedure that releases the transverse carpal ligament using a smooth thread passed through two needle entry points. No scalpel, no stitches, two bandaids. The entire procedure takes about 10 minutes under local anesthesia.
Dr. Jesse Dashe is the only surgeon in the San Francisco Bay Area offering TCTR, also known as the Guo Technique. His practice in San Leandro is reachable within a day's drive from anywhere in California.

No incision. No scalpel. Just two poke holes.
What is Thread Carpal Tunnel Release?
TCTR is a percutaneous release of the transverse carpal ligament performed under real-time ultrasound guidance. A thin thread is passed through two needle entry points in the palm and wrist, looped around the ligament, then moved back and forth to divide it. The median nerve is decompressed without cutting skin, fascia, or muscle.
Recovery is significantly faster than traditional open carpal tunnel release. The full return-to-work breakdown from Dr. Guo's published outcomes data is shown below.
The technique was developed by Dr. Danzhu Guo in Pennsylvania and has been performed in thousands of patients worldwide. Peer-reviewed outcomes studies show equivalent median nerve decompression with significantly faster return to function compared to open release.

Why is Dr. Dashe the only California provider?
TCTR requires specialized training in ultrasound-guided interventional hand surgery plus the specific Guo thread device. Most hand surgeons trained in the United States learned only open release or endoscopic release and have not yet added the incisionless approach to their practice.
Dr. Dashe trained directly in the technique and is currently the only surgeon across the nine-county San Francisco Bay Area performing it. As of 2026 there are no other California-based hand surgeons known to offer TCTR. Patients who want this procedure in California travel to San Leandro.

How out-of-town TCTR appointments work
Most out-of-town California patients complete care in one or two visits.
- Phone intake. Call (510) 297-0550 and the office team reviews your symptoms, prior workup, and insurance. If you have a nerve conduction study, fax or email it in ahead of time.
- Consultation. A 30-minute in-person exam with Dr. Dashe. Diagnosis is confirmed and TCTR is scheduled. For patients with clear diagnosis and recent nerve testing, consultation and procedure can sometimes be combined on the same day.
- Procedure day. About 45 minutes in the office including prep. Drive home the same day. No sedation, so you can drive yourself.
- Follow-up. A brief phone or video check-in at one week. In-person follow-up only if needed.
Frequently asked questions
Where can I get TCTR in California?
Dr. Jesse Dashe's office in San Leandro is the only California location currently offering Thread Carpal Tunnel Release. Patients travel from across the state.
Is TCTR the same as the Guo Technique?
Yes. "Guo Technique" refers to the specific ultrasound-guided thread method developed by Dr. Danzhu Guo. TCTR, Thread CTR, Thread Carpal Tunnel Release, and Incisionless Carpal Tunnel Release all describe the same procedure.
How is TCTR different from endoscopic release?
Endoscopic release still requires a small incision (about 1 cm at the wrist) to insert a camera and blade. TCTR uses only two needle punctures. No incision, no blade, no stitches. Full comparison here.
How is TCTR different from open release?
Open release uses a 2 to 3 cm incision in the palm and divides the ligament under direct vision. TCTR uses ultrasound guidance and a thread, no incision. Recovery is significantly faster. Full comparison here.
Is TCTR safe?
Published outcomes show safety comparable to open and endoscopic release. Ultrasound guidance lets the surgeon visualize the median nerve, ulnar artery, and ligament in real time throughout the procedure. Risks including incomplete release, nerve injury, and infection are rare.
Can I fly in for TCTR?
Yes. Patients fly in from Los Angeles, San Diego, Portland, Seattle, and further. Oakland (OAK) and San Francisco (SFO) airports are each under 30 minutes from the office. Most out-of-state patients fly in the day before and fly home the same afternoon as the procedure.

Is Thread Carpal Tunnel Release available in San Francisco?
TCTR is not currently offered inside San Francisco city limits. The closest provider is Dr. Jesse Dashe in San Leandro, a 20 to 30 minute drive across the Bay Bridge. SF patients routinely make the trip for the 10-minute, incisionless procedure.
Is TCTR available in the South Bay or San Jose?
No South Bay or San Jose surgeon currently offers Thread Carpal Tunnel Release. South Bay and Peninsula patients travel to San Leandro (about 40 minutes from San Jose, 30 minutes from Palo Alto) for TCTR with Dr. Dashe.
How far will California patients travel for TCTR?
Dr. Dashe sees TCTR patients from across Northern California, including Sacramento, Stockton, Fresno, Monterey, and the North Bay. The procedure is one visit of about 10 minutes plus brief recovery, so out-of-town patients typically drive in and drive home the same day.
Why isn't Thread Carpal Tunnel Release offered everywhere yet?
TCTR requires specialized training in ultrasound-guided interventional technique plus the specific Guo thread device. Most hand surgeons were trained on open or endoscopic release and have not yet adopted the incisionless approach. Dr. Dashe trained directly with the technique and brought it to the Bay Area.
Does insurance cover TCTR in California?
Most major insurance plans cover Thread Carpal Tunnel Release because it is coded as a carpal tunnel release procedure. Coverage varies by plan. Dr. Dashe's office verifies benefits before every procedure. Call (510) 297-0550 to confirm your plan.
