Ultrasound-Guided Carpal Tunnel

Persistent numbness, tingling, weakness, or pain in the hand can make everyday activities difficult and may be a sign of carpal tunnel syndrome. When symptoms continue despite conservative treatment, carpal tunnel release may be recommended to relieve pressure on the median nerve and restore hand function.

At Orthopaedic Specialists of Austin, our hand and upper extremity specialists offer SONEX™ Ultrasound-Guided Carpal Tunnel Release, an advanced minimally invasive procedure designed to treat carpal tunnel syndrome through a very small incision using real-time ultrasound guidance. Patients throughout Austin and the surrounding communities have access to this innovative treatment option through Dr. Harrison Kay, the only hand specialist in the Austin area currently performing the SONEX™ procedure. With specialized training and experience in ultrasound-guided carpal tunnel release, Dr. Kay combines advanced expertise with cutting-edge technology to help relieve symptoms with less discomfort, minimal scarring, and a faster return to daily activities compared to traditional surgical techniques.

Traditional carpal tunnel release is typically performed in a surgery center operating room setting through a larger incision in the palm and often involves a longer recovery period before patients can comfortably return to work, hobbies, and other daily activities. For appropriate candidates, SONEX™ offers a minimally invasive alternative designed to minimize tissue disruption while delivering effective symptom relief.

SONEX™ Ultrasound-Guided Carpal Tunnel Release uses real-time ultrasound imaging and specialized technology to precisely release the transverse carpal ligament that is compressing the median nerve within the wrist.

During the procedure, ultrasound allows the surgeon to clearly visualize important structures including nerves, tendons, blood vessels, and surrounding tissue. Through a very small incision, the ligament is released while minimizing disruption to surrounding tissues. The procedure is typically performed using local anesthesia and may be completed in an office-based setting for appropriate candidates.

This advanced approach offers several potential advantages compared to traditional open carpal tunnel surgery.

Potential benefits may include:

• Very small incision
• Real-time ultrasound visualization
• Minimal soft tissue disruption
• Reduced postoperative discomfort
• Minimal scarring
• Local anesthesia only for many patients
• Faster recovery and return to activities
• Lower need for pain medication
• Ability to perform the procedure in an office-based setting for appropriate candidates

Because ultrasound allows the surgeon to directly visualize important structures throughout the procedure, treatment can be performed with a high level of precision while minimizing disruption to surrounding tissues.

Carpal tunnel syndrome can often be diagnosed through a thorough medical history and physical examination. During the evaluation, symptoms will be discussed, hand strength and sensation will be assessed, and specific tests will be performed to identify nerve compression. Ultrasound can also help confirm the diagnosis and evaluate the severity of nerve compression by providing real-time visualization of the median nerve and surrounding structures. While nerve conduction studies (NCS) and electromyography (EMG) may still be recommended in certain situations, many patients can be accurately diagnosed and evaluated without these tests, allowing treatment decisions to be made more efficiently and comfortably.

The procedure begins with a thorough evaluation and confirmation that carpal tunnel syndrome is the source of your symptoms.

For appropriate candidates:

• Local anesthesia is administered
• A very small incision is made at the wrist
• Real-time ultrasound is used to visualize the carpal tunnel structures
• The transverse carpal ligament is released using specialized instrumentation
• A small dressing is applied following the procedure

Many patients can move their hand immediately following treatment and begin returning to light activities shortly afterward. Recovery timelines vary based on individual symptoms, job requirements, and overall health.
