Ultrasound-Guided Trigger Finger Release

Ultrasound-Guided Trigger Finger Release with UltraGuideTFR™

Performing ultrasound-guided trigger finger release with UltraGuideTFR allows for concurrent visualization of the internal structures of the palm and fingers. The ability to identify key anatomical landmarks via ultrasound supports a safe and successful transection of the pulley through a single small incision.

Benefits include:23-25

  • Performed in your clinic or procedure room
  • Can be performed using only local anesthesia
  • Return to normal daily activities in 3 days
  • Small incisions typically closed without sutures
  • Most patients only require acetaminophen or NSAIDS for pain management

Sleek, Simple and Secure

UltraGuideTFR features:

  • Introducer handle is lightweight and designed to facilitate single-hand use of device
  • The introducer is tapered at the tip, allowing the device to be inserted through a small incision
  • Curvature of the introducer supports safe and accurate placement between tendon and A1 pulley
  • Blade handle and post connection secures and protects blade until user is ready to deliberately advance and incise the sheath to transect A1 pulley
  • The device cutting blade and tip visible under ultrasound
  • Recessed space in the introducer protects the blade during device withdrawal

Ultrasound-Guided Trigger Finger Release with UltraGuideTFR

  1. Using direct ultrasound visualization, identify the relevant anatomical structures of the finger and hand.
  2. After visually confirming the anatomy, UltraGuideTFR is inserted through a small incision at the distal palmar crease just proximal to the A1 pulley.
  3. Once in position, the blade is advanced until it is distal to the A1 pulley and the blade handle is rotated up.
  4. The A1 pulley is incised by pulling the blade handle back into the finish position and rotated back down into the inactive position and locked.
  5. Complete release of the A1 pulley is confirmed using ultrasound prior to removing the device.
  6. Once UltraGuideTFR is removed, the incision can be closed with bandage or sutures as needed.
