Figure 4.

Intraoperative photographs of an open surgical treatment of a patient with no history of underlying systemic disease with a fourth trigger finger caused by an atypical nodule of the tendon and extensive local inflammation. In this case, the A1 pulley was sectioned and, due to the mechanical conflict caused by the nodule and the local inflammatory phenomenon, the local peritendinous tissue had to be excised, allowing intra-operative resolution of the trigger and subsequent clinical resolution, without recurrence.
