For Patients

What is Carpal Tunnel Syndrome (CTS)?

If you have carpal tunnel syndrome, you are not alone. CTS affects more than 12 million Americans,1 causing pain, and keeping people from work and leisure activities.

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

Non-surgical treatments:
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. Now there is a new surgical option—Micro-invasive Carpal Tunnel Release with the SX-One MicroKnife®.

A New Way to Treat Carpal Tunnel Syndrome for Rapid Recovery

Get out of pain, back to work, and back to life!

Micro-invasive Carpal Tunnel Release (CTR)

Ultrasound-guided CTR relieves the symptoms of carpal tunnel syndrome while minimizing recovery time.2,3 Developed by doctors at the Mayo Clinic, the SX-One MicroKnife® is the breakthrough device that allows ultrasound-guided CTR to be performed through a tiny incision.

Promotes Rapid Relief and Recovery

  • Incision is up to 5 times smaller than traditional CTR surgery4
  • Better outcomes reported with ultrasound-guided CTR than traditional surgery2,3
    • 5 times faster pain relief
    • 5 times faster return to normal daily activities
    • Minimal pain medication utilized

Ultrasound-guided CTR allows most patients to enjoy immediate motion so they can focus on getting back to their lives and the activities they love.2,3 If you have carpal tunnel syndrome and are considering a surgical procedure, Micro-invasive CTR may be right for you.
