Trigger Finger

Trigger finger is a condition that affects the tendons responsible for bending the fingers and thumb. When the tendon becomes irritated or inflamed, it can no longer move smoothly through its protective sheath, causing the finger to catch or lock during movement.

While trigger finger may begin as a minor annoyance, symptoms can progress over time and make daily activities increasingly difficult. Tasks such as gripping tools, buttoning clothing, opening jars, or typing may become painful and frustrating. At Fox Valley Orthopedics, we provide personalized treatment plans designed to reduce symptoms and restore normal hand function.

What Is Trigger Finger?

Tendons are strong bands of tissue that connect muscles to bones and allow the fingers to bend and straighten. Each tendon passes through a tunnel-like structure called a tendon sheath.

Trigger finger occurs when inflammation causes the tendon or tendon sheath to thicken, reducing the space available for smooth movement. As a result, the tendon may catch or become temporarily stuck as the finger moves.

In severe cases, the affected finger may lock in a bent position and require assistance to straighten.

What Types of Trigger Finger Are There?

Trigger finger can affect any finger or thumb and may vary in severity.

Trigger Thumb

Trigger thumb affects the tendon that controls thumb movement. Patients often experience clicking, pain, and difficulty bending or straightening the thumb.

Single-Finger Trigger Finger

Some patients develop symptoms in only one finger, commonly the ring finger, middle finger, or thumb.

Multiple-Finger Trigger Finger

In certain cases, multiple fingers may be affected simultaneously, especially in patients with underlying inflammatory or metabolic conditions.

Advanced Trigger Finger

Severe cases may cause the finger to lock completely in a bent or straightened position, significantly affecting hand function.

What Causes Trigger Finger?

Trigger finger develops when irritation or inflammation affects the flexor tendon system.

Common causes include:

• Repetitive gripping activities
• Frequent use of hand tools
• Repetitive hand motions
• Prolonged grasping activities
• Diabetes
• Rheumatoid arthritis
• Inflammatory conditions
• Previous hand injuries
• Age-related tendon changes

Many patients develop trigger finger without a specific injury or identifiable cause.

What Are the Symptoms of Trigger Finger?

Symptoms often develop gradually and may worsen over time.

Common signs and symptoms include:

• Finger stiffness, especially in the morning
• A clicking or popping sensation during movement
• Tenderness at the base of the finger or thumb
• Pain when bending or straightening the finger
• A small lump or nodule in the palm
• Finger catching during movement
• Finger locking in a bent position
• Difficulty gripping objects
• Reduced hand function

Symptoms are often most noticeable first thing in the morning or after periods of inactivity.

How Is Trigger Finger Diagnosed?

At Fox Valley Orthopedics, diagnosing a trigger finger typically begins with an examination by an orthopedic hand specialist.

How Is Trigger Finger Treated?

Treatment depends on symptom severity, duration, and how much the condition affects daily activities.

What Nonsurgical Treatments Are Available for Trigger Finger?

Many patients experience significant relief with conservative treatment.

Nonsurgical treatment options may include:

• Activity modification
• Rest
• Splinting
• Anti-inflammatory medications
• Stretching exercises
• Occupational therapy
• Corticosteroid injections

Corticosteroid injections are often highly effective for reducing inflammation and restoring smooth tendon movement.

When Is Surgery Recommended for Trigger Finger?

Surgery may be recommended when symptoms persist despite conservative treatment or when the finger becomes locked.

Trigger finger surgery typically involves releasing the constricted portion of the tendon sheath to allow the tendon to move freely.

Benefits of surgery may include:

• Reduced pain
• Improved finger motion
• Elimination of locking and catching
• Restoration of hand function

The procedure is almost always performed on an outpatient basis and has a very high success rate in terms of both outcomes and patient satisfaction.

What Does Trigger Finger Recovery Look Like?

Recovery depends on the severity of the condition and the treatment performed.

Patients receiving nonsurgical treatment may experience improvement within days or weeks following treatment, particularly after corticosteroid injections.

Following surgery, recovery often includes:

• Early finger motion exercises
• Temporary activity modifications
• Wound care
• Gradual return to normal activities
• Strengthening exercises as needed

Most patients regain normal finger function and return to everyday activities relatively quickly after treatment.

What Complications Can Occur if Trigger Finger Is Left Untreated?

Without treatment, trigger finger may continue to worsen and interfere with daily function.

Potential complications include:

• Persistent pain
• Permanent finger stiffness
• Chronic inflammation
• Loss of range of motion
• Difficulty performing daily tasks
• Finger locking in a fixed position
• Reduced grip strength

Early treatment can help prevent symptoms from progressing and improve long-term outcomes. Appointments with hand specialists at Fox Valley are easy to obtain in days rather than weeks, so you’ll be on the road to recovery quickly.
