The short answer
Carpal tunnel release relieves median-nerve compression by dividing the transverse carpal ligament. Dr. Gruner performs the innovative Sonex procedure using the SX-One MicroKnife under ultrasound guidance — no open incision, minimal scarring, immediate motion, and a return to normal activities within 3–6 days, far faster than traditional open surgery.

How it works
Carpal tunnel release treats severe carpal tunnel syndrome by dividing the transverse carpal ligament to relieve pressure on the median nerve. Rather than a traditional open incision, Dr. Gruner uses the Sonex (SX-One MicroKnife) technique under ultrasound guidance to release the ligament through a tiny opening.
The result is minimal scarring, immediate motion, and a rapid recovery — most patients return to normal activities within 3–6 days.
Why patients choose it
- Ultrasound-guided — no open incision
- Minimal scarring
- Immediate motion after the procedure
- Return to activities within 3–6 days

What to expect at your visit
- 1.
A focused conversation
Dr. Gruner reviews your history, prior imaging, and goals — what you want to get back to doing.
- 2.
Point-of-care ultrasound
When useful, a diagnostic musculoskeletal ultrasound evaluates the injury in real time, with no radiation.
- 3.
A clear, individualized plan
You leave understanding the diagnosis, the non-surgical options, and the expected timeline — in plain language.
Before and after your procedure
- How do I prepare for ultrasound-guided carpal tunnel release?
- Hold blood thinners only if Dr. Gruner advises, eat before your appointment, and arrange a ride if you prefer. The Sonex procedure is done in the office under local anesthesia through a tiny opening.
- What is aftercare like after carpal tunnel release?
- Most patients have immediate motion and only a small bandage to keep clean and dry for a day or two. Keep the hand elevated early on to reduce swelling, avoid heavy gripping briefly, and most people return to normal activities within 3–6 days.
- When will my carpal tunnel symptoms improve?
- Tingling and night symptoms often improve quickly, while numbness and strength can continue improving over weeks to months as the nerve recovers. Dr. Gruner monitors your progress.

Ultrasound-Guided Carpal Tunnel Release — Recovery Protocol
The ultrasound-guided carpal tunnel release lets what was once major surgery be done through a tiny incision. Care is tailored to you; these guidelines help you and your therapist.
Before & the day of
Prepare
- NSAIDs (ibuprofen/naproxen) may be used as needed for this procedure
- Avoid alcohol 48 hours before; don't drink while on prescription pain medicine
- Consider stopping tobacco/nicotine — it impairs healing
- No need to fast; arrange a ride home
First few days
Protect the wrist
- Keep the small incision clean and dry
- Elevate the hand to reduce swelling
- Avoid heavy gripping and lifting
Return to activity
Restore function
- Most patients return to normal activities within 3–6 days
- Night/tingling symptoms often improve first; numbness and strength recover over weeks
Clinical evidence
Selected peer-reviewed research supporting these approaches.
Frequently asked questions
- How is the Sonex carpal tunnel release different from traditional surgery?
- The Sonex procedure uses ultrasound guidance and the SX-One MicroKnife to release the ligament through a tiny opening rather than an open incision, meaning less scarring, immediate motion, and a return to activities in 3–6 days.
