What is a Trigger Finger Test?

Trigger finger, also known as stenosing tenosynovitis, is a condition that predominantly affects the fingers and thumbs, leading to pain, stiffness, and difficulty in moving the involved digit. This condition arises when the flexor tendons, responsible for bending the fingers, become inflamed or swollen. Consequently, the tendon's movement through the tendon sheath, specifically the A1 pulley at the base of the finger, is hindered. This disruption can cause the finger or thumb to lock in a flexed position and then suddenly snap straight, mimicking the action of pulling and releasing a trigger, thereby earning the name "trigger finger."

The treatment for trigger finger may involve various strategies. Initially, resting the affected digit, using a night splint to keep the finger straight, and applying anti-inflammatory medications are common non-surgical approaches. In cases where inflammation is significant, corticosteroid injections into the tendon sheath may be administered to reduce swelling and relieve pain.

In more severe or persistent cases, surgical treatment, known as trigger finger release surgery, may be necessary. This surgical procedure involves cutting the A1 pulley to allow the tendon to glide more freely. Trigger finger release surgery is usually considered after other treatments, like stretching exercises, hand therapy, or steroid injections, have failed to provide relief.

During a physical exam, medical professionals use the trigger finger test as a critical diagnostic tool. This involves asking the patient to perform specific movements with the affected finger or thumb, looking for any signs of triggering, finger locking in a flexed position, or difficulty in straightening the finger. This test helps in observing tendon movement and assessing the severity of the condition.

By carefully evaluating these symptoms through physical examination and considering patient history, healthcare providers, including hand therapists and orthopaedic surgeons, can accurately diagnose trigger finger. This comprehensive approach enables them to determine the most effective treatment plan, which may range from simple interventions like padded gloves to reduce inflammation and avoid injury, to more complex measures such as hand surgery, particularly in diabetic patients or those with other underlying medical conditions.

How does the Trigger Finger Test work?

You can easily conduct the Trigger Finger Test using our free template. Follow these steps to perform the exam:

Step One: Download the free worksheet

Access the printable Trigger Finger Test template through the link on this page or the Carepatron app, or download it from our resources library.

Step Two: Explain the Trigger Finger Test to your patient

Inform your patient that the Trigger Finger Test is designed to determine if they have trigger finger. Explain the condition's symptoms and how the test can help diagnose it.

Step Three: Perform the Trigger Finger Test

Utilize the instructions in the template to conduct the exam. Guide the patient through the specific finger movement and observe for triggering or locking.

Step Four: Evaluate the results

Once the test is complete, analyze the results. Look for triggering or locking during the finger movement, which can indicate the presence and severity of trigger finger.

Trigger Finger Test interpretation

The Trigger Finger Test is a valuable tool for assessing the likelihood of a trigger finger in patients. If your patient's finger exhibits triggering or locking during the test, it suggests the presence of trigger finger. The test's results can also help determine the appropriate course of action, whether conservative treatment or referral to a hand specialist.

It's important to note that the Trigger Finger Test is only one part of a comprehensive diagnostic process. Consider other factors when making a final diagnosis, such as age, medical history, and underlying conditions.

When to use the Trigger Finger Test?

You can use the Trigger Finger Test to assess any patient experiencing pain, stiffness, or limited movement in their fingers. Moreover, you can use our free worksheet to:

Assess the presence and severity of trigger finger in a patient

This template allows for the evaluation of trigger finger likelihood in patients. Additionally, it can help you assess the severity of the condition and provide recommendations for treatment options.

Determine if conservative or surgical treatments are needed

The results of this test can help guide your decision-making process when considering treatments for trigger finger. Non-surgical treatments may be sufficient for mild cases, whereas more severe cases may require surgical intervention.

Commonly asked questions

The trigger finger test is a diagnostic procedure used by healthcare professionals, typically orthopaedic surgeons or hand therapists, to identify trigger finger or trigger thumb. During this test, the patient is asked to flex and extend the affected finger or thumb. The doctor looks for symptoms like pain, finger locking in a bent position, difficulty in straightening the finger, and a clicking or snapping sound. This test helps in observing the movement of the flexor tendons through the tendon sheaths and identifying any hindrance due to swollen tendons or narrowed sheaths.

Common symptoms of trigger finger include stiffness, especially in the morning, a clicking or popping sensation when moving the finger, pain at the base of the finger or thumb, and the finger locking in a bent position before snapping straight. These symptoms can affect any digit, including the ring finger or thumb, with the thumb condition often referred to as 'trigger thumb'. The intensity of symptoms might vary based on the affected digit and severity of the condition.

Risk factors for developing trigger finger include repetitive gripping activities, certain medical conditions like diabetes and rheumatoid arthritis, and occupations or hobbies that strain the fingers (e.g., playing racket sports).

Age is also a factor, with most patients being between 40 and 60 years old. Trigger finger can affect multiple digits, and it's more common in the ring finger and thumb. In some cases, more than one finger is affected, known as trigger fingers.
