Trigger Finger
A finger that catches, locks, or pops when bending — caused by irritation of the flexor tendon and its sheath.
Trigger finger (stenosing tenosynovitis) is a condition in which one of the flexor tendons of the finger or thumb develops a nodule or thickening that catches as it tries to slide through the A1 pulley — a fibrous tunnel at the base of the finger. The result is the classic catching, popping, or locking sensation. Lifetime prevalence is roughly 2–3% in the general population and rises to 10–20% in people with diabetes (Makkouk et al., Curr Rev Musculoskelet Med 2008). It most commonly affects the thumb, ring, and middle fingers of the dominant hand.
Early on, patients typically notice mild stiffness and a painless click when bending or straightening the finger, often worst first thing in the morning. As the condition progresses, the finger may catch and require extra effort — or the other hand — to straighten, and a tender nodule can usually be felt in the palm at the base of the affected finger. In advanced cases the finger locks in a bent position. Pain is usually localized to the palm but can radiate into the finger itself.
Trigger finger is most common in adults between ages 40 and 60 and affects women roughly 4–6 times more often than men (Wolfe, Green's Operative Hand Surgery). Risk is elevated in people with diabetes, rheumatoid arthritis, hypothyroidism, and gout, as well as in occupations and hobbies involving sustained gripping or repetitive pinching — tradespeople, musicians, hairstylists, dental professionals, climbers, racquet-sport players, and heavy phone or tool users.
A combined, root-cause approach.
Systematic reviews (Fiorini et al., Hand Surg Rehabil 2018; Lunsford et al., J Hand Ther 2019) support conservative management — including manual therapy, tendon gliding exercises, and activity modification — as effective first-line care for most cases of trigger finger, particularly when treated early. We release restrictions in the flexor tendons, forearm muscles, and surrounding fascia with ART and Graston, calm overactive forearm trigger points with dry needling, mobilize the small joints of the wrist and hand, and prescribe tendon-gliding and eccentric loading exercises so the tendon can move freely through the pulley again.
