Can psoriatic arthritis cause trigger finger
Can psoriatic arthritis cause trigger finger Psoriatic arthritis is a chronic inflammatory disease that affects both the skin and joints, often causing pain, swelling, and stiffness. While it primarily targets the joints and entheses (the sites where tendons or ligaments insert into bone), it can also have a variety of musculoskeletal manifestations. One such concern that has garnered attention is whether psoriatic arthritis can cause trigger finger, a condition characterized by catching or locking of the fingers due to a mismatch between the flexor tendons and the pulley system that guides their movement.
Trigger finger, medically known as stenosing tenosynovitis, occurs when the flexor tendons become inflamed or swollen, impeding their smooth glide through the pulley system within the finger. This results in episodes where the finger catches, locks, or snaps during movement, often accompanied by pain and tenderness. The condition most commonly affects middle-aged individuals but can be seen in younger populations, especially those with underlying inflammatory or systemic conditions.

Can psoriatic arthritis cause trigger finger In patients with psoriatic arthritis, the likelihood of developing trigger finger is increased due to the disease’s inflammatory nature. Psoriatic arthritis often involves dactylitis (sausage digits) and enthesitis, both of which involve inflammation at sites where tendons and ligaments attach to bone. This inflammation can extend to the flexor tendons and their surrounding synovial sheaths, leading to tenosynovitis—a swelling and inflammation of the tendon sheath. When the flexor tendons of the fingers become inflamed, their movement through the pulley system can be restricted, creating a scenario similar to trigger finger.

This narrowing predisposes individuals to develop trigger finger symptoms. Additionally, the systemic inflammation associated with psoriatic arthritis can contribute to tissue degeneration, fibrosis, and the formation of nodules, all of which can interfere with normal tendon movement.
It is important to distinguish between trigger finger caused by psoriatic arthritis and other causes such as repetitive strain, osteoarthritis, or age-related degenerative changes. While trigger finger can occur independently, in psoriatic arthritis patients, its development often signals active inflammation that may require targeted treatment. Managing the underlying inflammation with disease-modifying antirheumatic drugs (DMARDs) or biologic therapies often helps alleviate symptoms, including those related to trigger finger.
Can psoriatic arthritis cause trigger finger In some cases, when inflammation and conservative treatments do not resolve the condition, local corticosteroid injections or even surgical release of the affected pulley may be necessary. Addressing both the systemic disease and local symptoms provides the best chance for relief and preservation of finger function.
In conclusion, psoriatic arthritis can indeed cause trigger finger by promoting inflammation of the tendons, tendon sheaths, and pulley system within the fingers. Recognizing this connection is crucial for timely intervention, which can significantly improve quality of life and prevent long-term disability. Can psoriatic arthritis cause trigger finger
