Part VIII: Tendons and Soft Tissues

Trigger finger is one of the most common problems seen in the clinical practice of orthopedic surgery. It is caused by a disproportion between the flexor tendons and their sheath, and it presents with painful triggering or locking of the affected digit during finger motion. The most common form of trigger finger is the primary type, which is found most frequently among middle-aged women, two to six times more commonly than it is observed in men. The most commonly affected digit is the thumb, followed by the long, ring, index, and little fingers. The involvement of several fingers is not unusual. Secondary trigger finger can be found in patients with diabetes, gout, renal disease, and rheumatoid diseases, and it is associated with a worse prognosis after conservative management.
