What is Carpal Tunnel Syndrome (CTS)?

Affecting more than 12 million people, Carpal Tunnel Syndrome (CTS) can cause pain, numbness, and tingling in the hand and arm. It occurs when the median nerve, one of the major nerves in the hand, is compressed as it travels through the carpal tunnel in the wrist.

Traditional Carpal Tunnel Release Surgery

CTS may be treated surgically through a procedure called carpal tunnel release (CTR), which relieves pressure on the median nerve by cutting the transverse carpal ligament. Traditional CTR procedures can remedy the condition but may result in large and sometimes painful scars, ongoing palmar pain, and a long road to recovery.

Recovery In Days, Not Months

Our practice is one of the first to perform the Sonex carpal tunnel release with real-time ultrasound guidance so patients can return to work and activities in less time.

Carpal Tunnel Release (CTR) with the SX-One MicroKnife^®

The SX-One MicroKnife is a low-profile, safe, and effective instrument that allows your doctor to perform carpal tunnel release in a matter of minutes. When combined with ultrasound visualization, the procedure requires only a very small (4-5 mm) wrist incision.

Significant benefits of the SX-One MicroKnife

• Performed in a procedure room or office setting
• Can be performed using local anesthesia
• Small wrist incision is typically closed without sutures
• Reduces or eliminates the need for opioids
• Postoperative therapy is typically not required—saving you time and money
• Immediate motion in the hand for rapid recovery
• Return to normal activity in a few days, not months

After the procedure, you’ll be able to resume activities as tolerated—most patients can return to work and the activities they love within 3-6 days.

Micro-invasive CTR under Ultrasound Guidance*

1. A 4-5 mm micro-incision is made in the wrist.
2. Under ultrasound guidance, the SX-One MicroKnife is inserted through the micro-incision.
3. Stealth MicroGuards™ are deployed to enhance the protection of nearby nerves, tendons, andother sensitive anatomy during the procedure.
4. The TCL Blade™ is advanced and cuts the TCL in the wrist to reduce pressure in the carpal tunnel.
5. The SX-OneMicroKnife is removed and the micro-incision is closed with an adhesive bandage or strip; sutures or stitches are optional.

*Micro-invasive CTR can also be performed with a traditional mini-open incision. Ask your doctor for more information.
