Abstract
BACKGROUND: Open A1 pulley release for trigger finger has generally been considered a minor procedure with infrequent complications. Most reported complications are minor, including scar pain and tenderness, mild extension lag, and recurrence of triggering. Rates of major complications, such as bowstringing, neurovascular bundle injury, and infection requiring reoperation, are less than 1% to 4%. We aimed to describe the potentially devastating sequelae of these major complications and the subsequent consequences. METHODS: Three patients underwent open trigger finger release, which were all complicated by severe postoperative surgical site infection requiring multiple subsequent procedures. We review our initial management, subsequent reconstructive options, and outcomes with up to 19 years follow-up. RESULTS: All 3 adult patients who underwent open A1 pulley release for trigger finger developed a surgical site infection, leading to flexor tenosynovitis requiring urgent operative debridement and multiple subsequent procedures. Two patients were poorly controlled diabetics, and the third patient was otherwise healthy. Each patient ultimately developed distinct consequences from their postoperative course-finger stiffness and contracture, disabling bowstringing requiring the use of a pulley ring, and flexor tendon rupture requiring staged tendon reconstruction, respectively. All 3 patients at final follow-up had a permanent functional deficit. CONCLUSIONS: Major complications after trigger finger release are infrequent. However, if left untreated, particularly in diabetic patients, there can be disastrous consequences, resulting in permanent loss of function. This case series highlights the importance of accurate diagnosis of postoperative infections and expedient treatment thereafter.
