Trigger Finger: Symptoms, Causes, and Treatment Options

Trigger finger is a common condition that can make it difficult, and sometimes painful, to bend or straighten your finger or thumb. You may notice a catching, clicking, or locking sensation when you try to move it.

At Lakeshore Bone & Joint Institute, our hand specialists provide comprehensive care for trigger finger, offering both nonsurgical and surgical treatment options to restore smooth, pain-free movement.

What is Trigger Finger?

Trigger finger (also called stenosing tenosynovitis) occurs when inflammation narrows the space within the tendon sheath in your finger. This prevents the tendon from gliding smoothly, leading to stiffness, catching, or locking.

It most commonly affects the thumb, middle finger, or ring finger.

Symptoms of Trigger Finger

Trigger finger symptoms often develop gradually and may worsen over time. Common signs include:

A catching or clicking sensation when moving the finger
Finger stiffness, especially in the morning
Tenderness or a small lump at the base of the finger or thumb
Difficulty straightening the finger
Finger locking in a bent position, sometimes requiring the other hand to straighten it
In more advanced cases, the finger may become stuck in a bent or straight position.

Causes of Trigger Finger

Trigger finger is typically caused by irritation or inflammation of the tendon sheath. Contributing factors may include:

Repetitive gripping or hand use
Jobs or hobbies involving forceful hand movements
Diabetes
Rheumatoid arthritis
Previous hand injuries

Trigger finger is usually diagnosed through a physical examination. Your orthopedic specialist will evaluate:

Finger movement and range of motion
Areas of tenderness or swelling
Whether the finger locks or catches during motion

Trigger Finger Treatment Options

Treatments for trigger finger depend on the severity of your symptoms and how long they have been present.

Many cases of trigger finger can be managed without surgery. Options may include:

Rest and activity modification to reduce irritation
Splinting to limit movement and allow healing
Anti-inflammatory medications to reduce swelling
Corticosteroid injections to relieve inflammation and improve tendon movement

In many patients, these treatments can significantly reduce symptoms or resolve the condition entirely. Physical therapy or hand exercises may be recommended to restore strength and flexibility.

If symptoms persist despite nonsurgical treatment or if the finger becomes locked, a minor surgical procedure may be recommended. Trigger finger surgery is a quick, outpatient procedure that involves releasing the tight portion of the tendon sheath, thereby allowing the tendon to move freely again.
