Abstract

Trigger finger commonly occurs in A1 pulley. However, there have been occasional reports of proximal or distal A2 pulley and A3 pulley at other sites. Especially, trigger finger that occurs in A2 pulley is usually due to thickening of flexor tendon. Flexor tendon plasty surgery or A2 pulley partial release are well known treatments of A2 pulley trigger finger. We conducted pulley lengthening of the A2 pulley to a 62-year-old man who has trigger finger occurring in distal portion of the A2 pulley, and we report about this with good results obtained.
