Trigger Finger
Trigger finger, medically known as stenosing tenosynovitis, is a common condition causing pain and stiffness in a finger or thumb.
It occurs when the pulley system at the base of the finger becomes inflamed, narrowing the space for the tendon to glide smoothly.
This inflammation can cause the tendon to develop a small nodule.
The primary symptom is a catching or locking sensation when you try to bend or straighten the affected digit.
This may be accompanied by a popping or clicking sound, stiffness (especially in the morning), and tenderness at the base of the finger.
In severe cases, the finger can lock in a bent position. The exact cause is often unknown, but repetitive gripping motions can contribute.
It is more frequent in individuals with diabetes, rheumatoid arthritis, or between the ages of 40 and 60.
Treatment typically begins conservatively. Rest, over-the-counter anti-inflammatory medication, and wearing a splint can allow the inflammation to subside.
If symptoms persist, your orthopaedic doctor may recommend a corticosteroid or platelet rich plasma (PRP) injection into the tendon sheath, which is highly effective.
For chronic or severe locking, a minor surgical procedure to release the constricted pulley can provide a permanent solution, restoring smooth, pain-free movement.
