The TFS provides a pad over the A-1 pulley to relieve pressure during daily activities without interfering with hand function. It cushions the fat pad at the base of the finger and may completely reverse the trigger finger, making more aggressive treatments unnecessary. The TFS also assists in identifying the cause of the inflammation, which is often handling of certain objects. For size measure finger circumference mid-way between the base of the finger and the PIP joint. Due to anatomical differences or swelling, a larger size may be necessary. Latex free.
