Trigger fingers requiring simultaneous division of the A1 pulley and the proximal part of the A2 pulley.

In a prospective study of 50 adult patients with primary idiopathic trigger finger, four patients (8%) required simultaneous division of the proximal 3 to 4mm of the A2 pulley as well as the A1 pulley in order to completely resolve the triggering. At final follow up at 6 to 12 months, all patients were symptom-free with a full range of motion of the fingers. This entity is discussed.
