Thread Carpal Tunnel Release in California

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 roughly three times faster than traditional open carpal tunnel release. Most office workers return to keyboard work within 1 to 5 days. Manual laborers average 12 days compared to about 33 days for open surgery. Approximately 90 percent of non-manual-labor patients are back to normal activity within one week.

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.

1. 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.
2. 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.
3. Procedure day. About 45 minutes in the office including prep. Drive home the same day. No sedation, so you can drive yourself.
4. 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 roughly three times 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.
