In the treatment of trigger finger, which joint is immobilized for 3 to 6 weeks?

Trigger finger happens when the flexor tendon sheath at the A1 pulley becomes thickened and catches as the finger moves. To give that pulley a rest and allow healing, the joint most directly involved is immobilized. Immobilizing the MCP joint in a flexed position for about 3 to 6 weeks reduces tendon movement across the A1 pulley, unloading the pulley and letting the sheath settle. The other joints (PIP, DIP) aren’t the site of the pulley where this problem occurs, and immobilizing the wrist wouldn’t address the triggering. After this immobilization period, gradual tendon gliding and range-of-motion exercises are started to restore function; if symptoms persist, alternatives like injections or surgery may be considered.
