Also called stenosing tenosynovitis, trigger finger causes one or more of your fingers or thumbs to get stuck in a bent position. It typically occurs in the thumb or ring finger but may affect multiple digits on both hands.
Trigger finger occurs when the fibrous cords of tissue (tendons) that attach muscle to bone and control finger or thumb movement become irritated or inflamed.
Each tendon is enclosed in a protective membrane called a sheath. Your tendons normally slide easily through this tube-like structure, allowing smooth, frictionless movement. However, inflammation and swelling of the tendon sheath cause narrowing (stenosis), which can interfere with the normal gliding motion of a tendon.
Left untreated, prolonged irritation of the affected tendon sheath can result in scarring and nodules in the tendon itself. This further restricts tendon movement through the sheath, eventually resulting in a permanently bent digit.
Trigger finger symptoms generally develop slowly, worsen over time, and may include:
These symptoms are usually worse in the morning or after prolonged inactivity and often lessen as you flex and straighten your fingers. However, the affected digits may lock in the bent position as the tendon damage worsens.
Depending on your symptoms, your North Point Orthopaedics provider may recommend resting from activities that can cause or worsen tendon irritation and inflammation.
You may also respond well to splinting, which straightens and holds the affected digit in place for several weeks. Gentle stretching exercises can help restore flexibility to your finger(s) or thumb(s), and over-the-counter anti-inflammatories may help with the discomfort.
For more severe symptoms that interfere with your daily routine, your hand specialist may recommend a steroid injection to relieve inflammation and restore smoother motion of the tendon through the sheath. This can reduce your symptoms for up to a year.
If problems persist or recur, your best treatment option may be an in-office procedure (percutaneous release) or minimally invasive surgery to open the narrowed tendon sheath.
