Trigger Finger

Trigger finger, medically known as stenosing tenosynovitis, occurs when a finger tendon becomes irritated and thickened, making it difficult to glide smoothly through its sheath. This may cause the finger to catch, lock, or snap during movement.

Symptoms commonly include stiffness, tenderness at the base of the finger, and a locking sensation when bending or straightening. Finger splints may help limit motion and allow the irritated tendon to rest during recovery.

Common symptoms of trigger finger

• Finger catching or locking
• Pain or tenderness at the base of the finger
• Stiffness, especially in the morning
• Snapping sensation during movement

Choosing the right support

Finger splints are typically used to limit motion of the affected joint and reduce tendon irritation. Some individuals wear splints at night, while others use them during aggravating activities.
