What is carpal tunnel syndrome (CTS)?
CTS is a common condition that causes pain, numbness, and tingling in the hand and arm. The condition occurs when one of the major nerves in the hand—the median nerve—is compressed as it travels through the wrist.
The median nerve controls movement in the thumb and feeling in the thumb and first three fingers. It runs down the arm and forearm, passes through the carpal tunnel at the wrist, and goes into the hand.
Common CTS Symptoms
- Numbness, tingling, burning and pain in the thumb and index, middle, and ring fingers
- Occasional shock-like sensations that radiate to the thumb and index, middle, and ring fingers
- Pain or tingling that may travel up the forearm toward the shoulder
- Weakness in the hand
Traditional CTS Treatment Options
Mild symptoms of CTS can be treated with directed home care, which may include specific exercises, avoiding activities that cause symptoms, or wearing a wrist splint. Medications or corticosteroid injections may also be recommended.
Carpal tunnel release surgery:
More severe cases of CTS may be treated surgically through carpal tunnel release (CTR), which involves cutting the transverse carpal ligament (TCL) to relieve pressure on the median nerve. 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.
A New Way to Treat Carpal Tunnel Syndrome for Faster Recovery
Micro-invasive Carpal Tunnel Release (CTR) with the SX-One MicroKnife™
Micro-invasive CTR relieves the symptoms of carpal tunnel syndrome, while minimizing recovery time. Developed by doctors at the Mayo Clinic, the SX-One MicroKnife™ allows your doctor to perform CTR through a tiny incision under ultrasound guidance.*
Protects Anatomy and Promotes Rapid Recovery
- Incision is up to five times smaller than the incision made during traditional CTR1
- Better outcomes with ultrasound-guided CTR than traditional surgery2,3
- 5 times faster pain relief
- Promotes rapid recovery
- 5 times faster return to normal daily activities
- Minimal pain medication utilized
- Consistent safe zone enhances protection of sensitive anatomy during ligament cutting2,3
With Micro-invasive CTR you’ll have immediate motion so you can focus on getting back to your life and the activities you love.2,3 If you have carpal tunnel syndrome and are considering a surgical procedure, Micro-invasive CTR with the SX-One MicroKnife™ may be right for you.
Micro-invasive CTR under Ultrasound Guidance*
- A 4-5 mm micro-incision is made in the wrist
- Under ultrasound guidance, the SX-One MicroKnife™ is inserted into your wrist through the micro-incision
- Stealth MicroGuards™ are deployed to enhance the protection of nearby nerves, tendons, and other sensitive anatomy during the procedure
- The TCL Blade™ is advanced and cuts the TCL in the wrist to reduce pressure in the carpal tunnel
- The SX-One MicroKnife™ 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.
