The short answer
Both open surgery and ultrasound-guided carpal tunnel release divide the transverse carpal ligament to take pressure off the median nerve. The ultrasound-guided release does it through a tiny opening instead of an open incision, so there is minimal scarring, the hand can move right away, and most patients are back to normal activities within about a week. Dr. Marc Gruner, DO, performs ultrasound-guided carpal tunnel release with UltraGuideCTR™ from Sonex Health in Bethesda, MD.

Carpal Tunnel Surgery Guide — Dr. Marc Gruner
Carpal tunnel syndrome happens when the median nerve is pinched at the wrist, causing pain, numbness and tingling in the thumb, index and middle fingers, often worse at night and with typing. Diagnosis combines a clinical exam, EMG nerve testing and ultrasound imaging of the nerve.
Most patients start with nerve-glide physical therapy and a night brace, adding a steroid injection or PRP if needed. A release is for severe or persistent cases. When one is needed, the question is how it is done.
How the two approaches compare
| Ultrasound-guided release | Traditional open surgery | |
|---|---|---|
| What is released | The transverse carpal ligament | The transverse carpal ligament |
| Access | A tiny opening, guided by live ultrasound (UltraGuideCTR™) | An open incision |
| Scarring | Minimal | An incision scar |
| Moving the hand | Immediately after the procedure | Limited while the incision heals |
| Back to normal activities | Most patients within about a week | Longer |
Why ultrasound makes the difference
Ultrasound shows the median nerve, the ligament and the surrounding structures in real time, so the release can be done precisely through a very small opening rather than by exposing the whole area. Dr. Gruner uses UltraGuideCTR™, developed by Sonex Health, a company founded by Mayo Clinic physicians. He trained in ultrasound-guided procedures at Mayo Clinic and is registered in musculoskeletal sonography (RMSK).
Frequently asked questions
- Can carpal tunnel be treated without open surgery?
- Yes. Many patients improve with nerve-glide therapy, a night brace, a steroid injection or PRP. When a release is needed, an ultrasound-guided release divides the same ligament through a tiny opening, with minimal scarring and a faster return to activity.
- How long is recovery after ultrasound-guided carpal tunnel release?
- The hand can move immediately, and most patients return to normal activities within about a week.
- Who performs ultrasound-guided carpal tunnel release in Bethesda, MD?
- Dr. Marc Gruner, DO, a Mayo Clinic–trained sports medicine physician, performs ultrasound-guided carpal tunnel release with UltraGuideCTR™ at OrthoBethesda in Bethesda, MD, for patients across Maryland, Washington, DC and Northern Virginia.
