Why Does My Finger Lock or Get Stuck? Understanding Trigger Finger

By: Dr. Daniel Buchan, Orthopedic Surgeon

Have you ever tried to straighten your finger only to feel it catch, click, or temporarily lock in place? Maybe you notice stiffness when you wake up, or you have to use your other hand to straighten a finger that seems stuck in a bent position. These symptoms can be signs of a condition called trigger finger, a common hand problem that can make everyday activities such as gripping a steering wheel, holding a golf club, opening a jar, or using tools uncomfortable.

Although trigger finger can sometimes improve with conservative treatment, persistent symptoms may require surgical intervention. Understanding what's happening inside your hand is the first step toward finding the right solution.

What Causes Trigger Finger?

Trigger finger, or stenosing tenosynovitis, occurs when a tendon that bends your finger or thumb cannot glide smoothly through the surrounding tissue. Tendons connect muscles to bones and allow your fingers to bend and straighten. In your hand, these tendons travel through protective tunnels and are held close to the bones by structures called pulleys.

When a tendon or its surrounding sheath thickens or becomes irritated, the tendon may have difficulty passing through the pulley at the base of the finger. This can cause the catching, clicking, or locking sensation associated with trigger finger. The condition can affect any finger, including the thumb, and may involve more than one finger at a time.

What Are the Common Symptoms?

Trigger finger symptoms often develop gradually, although their severity can vary. Common signs include:

• Clicking or popping when bending or straightening a finger
• Stiffness, particularly in the morning
• Tenderness or a small lump near the base of the affected finger
• Pain when gripping or using the hand
• A finger that catches or temporarily locks in a bent position
• Difficulty fully straightening the finger

In more advanced cases, a finger may become locked in a bent position and require assistance to straighten. Occasionally, it may become difficult or impossible to straighten completely. Trigger finger is more common in people with certain medical conditions, including rheumatoid arthritis and diabetes. Repetitive gripping activities may also aggravate symptoms, although the condition doesn't always have an identifiable cause.

Will Trigger Finger Go Away on Its Own?

Mild cases of trigger finger may improve with activity modification and conservative treatment. However, symptoms that persist, worsen, or interfere with daily activities should be evaluated. Depending on severity, initial treatment may include reducing activities that aggravate symptoms, splinting to limit tendon irritation, and non-steroidal anti-inflammatory drugs (NSAIDs) to help manage discomfort. A corticosteroid injection may also be recommended to reduce inflammation and improve tendon movement. Injections can help many patients, although results vary and symptoms may return. Ultimately, the right treatment depends on how long your symptoms have lasted, their severity, your medical history, and how much the condition affects your ability to use your hand.

When Is Surgery an Option?

When conservative treatments don't provide adequate relief, or a finger continues to lock and interfere with normal function, a procedure called trigger finger release may be considered. During the procedure, the surgeon releases the constricted portion of the pulley that is preventing the tendon from moving freely. This creates more room for the tendon to glide as the finger bends and straightens.

At Bluewater Orthopedics, trigger finger release is one of the procedures we may perform through our In-Office Hand Surgery program. For appropriate patients, an in-office procedure can offer a convenient alternative to having surgery in a hospital or outpatient surgery center, often with lower facility-related costs and without the need for general anesthesia. However, not every patient requires surgery, and not every patient is an appropriate candidate for an in-office procedure. The decision is based on your diagnosis, medical history, symptoms, and individual treatment needs.

Don't Let a Stuck Finger Interfere With Everyday Life

Your hands play an important role in nearly everything you do, from working and exercising to preparing meals, enjoying hobbies, and spending time with family. When a finger repeatedly catches or locks, even simple activities can become frustrating or uncomfortable. The good news is that trigger finger is treatable, and many patients find relief through nonsurgical care or a relatively straightforward procedure when surgery is appropriate.
