Trigger Finger

Trigger finger is a condition in which a finger tendon has trouble gliding smoothly as you bend or straighten the finger. This can cause the finger to catch, click, or lock in a bent position before releasing. Adults are commonly affected, and the thumb can develop the same problem, known as trigger thumb. Symptoms may range from mild catching to a finger that stays locked.

The flexor tendon normally glides through a pulley at the base of the finger. Swelling, irritation, or thickening can narrow this passage, so the tendon catches as it moves and causes clicking, locking, or a painful release. Repetitive hand use may contribute in some people, but it is not always the only cause, and a single cause may not be identifiable.

The same process can affect the thumb, where it is called trigger thumb. Not every case is caused by an injury or overuse.

Trigger finger is usually treatable, but prolonged symptoms can make everyday tasks harder and may require more involved treatment.

A clinician will ask about clicking, locking, pain, how long symptoms have lasted, and activities that affect your hand. They will examine the palm and finger while you bend and straighten it, and may feel for tenderness or a small nodule near the affected pulley.

Treatment for trigger finger depends on the severity and duration of symptoms. The main goals are to reduce pain and inflammation and restore smooth movement of the affected finger.

Activity Modification

Avoiding or reducing activities that require repetitive gripping or forceful hand movements can help relieve symptoms. Resting the affected finger may reduce irritation of the tendon.

Splinting

A splint may be used to keep the affected finger in a straight or neutral position, particularly at night. This can reduce tendon irritation and allow the finger to rest.

Pain Relief

Nonsteroidal anti-inflammatory drugs (NSAIDs) may help reduce pain and inflammation. Their use should be appropriate for the individual’s health conditions and other medications.

Corticosteroid Injection

A corticosteroid injection into the tendon sheath can reduce inflammation and improve finger movement. It is often considered when symptoms do not improve with conservative treatment.

Hand Therapy

Gentle stretching and strengthening exercises may help maintain finger mobility and function. A hand therapist can provide exercises appropriate for the patient’s condition.

Surgery

Surgery may be recommended when symptoms are severe, persistent, or do not respond to nonsurgical treatments. The procedure releases the constricted part of the tendon sheath, allowing the tendon to move more freely.

Treatment is individualized according to symptom severity, duration, and response to previous treatments. Most patients experience significant improvement with appropriate management.

Trigger finger is generally manageable and often improves with treatment, but the timeline varies. Symptoms may return, or another finger may become affected, particularly in people with associated conditions such as diabetes.

After an injection or trigger finger release surgery, soreness, swelling, and stiffness may occur, followed by a gradual return of movement. Recovery and symptom improvement vary, so follow-up with the treating clinician helps guide activity and rehabilitation.
