Diagnosis: Trigger Finger Trigger finger, also known as stenosing tenosynovitis, is a painful condition of the finger accompanied by either a locking or catching sensation. The most common cause of trigger finger is inflammation or scarring of the A1 pulley, prohibiting the flexor digitorum profundus and superficialis tendons from gliding smoothly. On ultrasound, the A1 pulley can be easily seen, and it is often thickened in patients with trigger finger. Ultrasound-guided cortisone injection into the tendon sheath is an effective treatment for trigger finger. Surgical release of the A1 pulley may be required in refractory cases. Ultrasound-guided percutaneous release of the A1 pulley is also an option at some centers.
