Trigger finger/thumb

Intro: Trigger finger/thumb is a condition where the flexor tendon of the finger or thumb is stuck as it glides through a pulley resulting in the digit to lock. This is caused by thickening of the tendon or pulley. Diabetes is a risk factor for this condition, although there may be no cause in getting trigger finger/thumb.

Symptoms: Pain and the finger/thumb to lock in flexion at times.

Treatment: Medication, activity modification, or a steroid injection at the level of the pulley. In unimproved cases, surgical release of the pulley may help.
