Ultrasound-Guided Tenotomy: Part 2 Procedure
As a follow up to the review of evidence on percutaneous ultrasound guided tenotomy, the specifics of the procedure and options will be covered in the following post. As mentioned, tendinopathy is very commonly seen in sports medicine clinics and can be very challenging to treat. More than 20 million There are many patients that may still be symptomatic after multiple courses of physical therapy, soft tissue modalities and other treatment options. Other patients may be unwilling to go through the physical therapy programs associated with tendinopathy.
A 45 year old recreational golfer presents with right lateral elbow pain. She describes pain with gripping his club over the lateral elbow and has seen one other provider for this problem. She states he underwent an injection for this that seemed to help for about 2 months. After the pain returned, she started to research options and has questions about percutaneous ultrasound guided tenotomy. She read that there were certain providers that use ultrasound guidance. Which of the following is NOT an advantage of ultrasound guided injections when compared to palpation-guided injections?
A. Improved accuracy
B. Increased response rate
C. Reduced procedural pain
D. Smaller volume of fluid aspirated
Tenex Health, Inc., a privately held, U.S.-based medical technology company providing healthcare professionals with minimally invasive technologies to treat chronic pain in soft and hard tissue. The Tenex technology (particularly the TX1 system) was cleared by the FDA in 2011. The procedure is performed through a small skin incision and uses ultrasonic energy to break down and remove scar tissue in the damaged region, creating an acute inflammatory reaction and facilitating tendon healing. This is a similar theory of competing treatment options such as prolotherapy with the acute inflammatory reaction. For this reason, most providers recommend stopping any non-steroidal anti-inflammatory medications one week prior to the procedure and not continuing these for 1-6 weeks, depending on the provider.

The TX-Bone was the last of the handpieces to get approval in 2019. The indications for this include tendinopathy with calcifications, osteophyte or spur formation. This includes the rotator cuff, triceps, gluteal region, achilles insertion, plantar fascia and possibly exostosis. The length is 33.0 mm, the needle tip gauge is 15 and the sheath size is 11. It has a 650 % volume compared to the TX1 handpiece.

This is many times called the FAST technique, which stands for Focused Aspiration of Scar Tissue. Most patients undergo one procedure. General instructions include local over the counter medications including acetaminophen or cold compresses. Gentle range of motion exercises should be done over the first 48 hours. Most people can return to work over the next 1-10 days depending on the patient and procedure performed. It is recommended that no weight bearing activity is performed for at least two weeks with the affected area if possible. Physical therapy may be utilized and recovery time is normally 4-6 weeks.
D is the correct answer. Percutaneous ultrasound guided tenotomy is a treatment option for lateral epicondylosis and requires use of ultrasound. The benefits of ultrasound guidance when performing injections include a larger volume of fluid aspirated, not a smaller volume. It has been shown that ultrasound guidance improves accuracy and response rate and reduced procedural pain has also been reported.
