Ultrasound-assisted Hand Surgery: Percutaneous Tendon Release

Percutaneous tendon sheath release has traditionally been performed only by a few hand surgeons. While this technique has the advantage of minimal scarring, no need for sutures and a fast return to daily activities, there is a slight risk of injury to peripheral nerves and the tendon itself. Ultrasound-guided percutaneous tendon release has gained popularity in recent years, with multiple reports on its benefits. However, most existing methods rely on small knife or needle. 

The main challenge of these methods is that the surgeon needs to hold the ultrasound transducer with one hand while manipulating the surgical instruments with the other, which may compromise accuracy and safety. 

To address these limitations, we have developed a new unique instrument for ultrasound-guided percutaneous tendon release. This device is designed to increase the ease and safety of the procedure by separating the act of inserting the ultrasound-guided device into the tendon sheath from the act of cutting the sheath itself. This separation improves control during the procedure and reduces the risk of iatrogenic injury. 

In this presentation, the author will describe his experience with approximately 700 cases using this technique and present the practical application and effectiveness of this technique in clinical practice.
