Trigger Finger, medically known as Stenosing Tenosynovitis, is a common hand condition that affects the tendons responsible for bending the fingers or thumb. Tendons normally glide smoothly through protective tunnels called tendon sheaths. When the tendon or its sheath becomes inflamed, thickened, or swollen, the tendon cannot move freely.

As a result, the finger may catch, lock, or snap during movement—similar to pulling and releasing a trigger. In severe cases, the finger may become locked in a bent position and require assistance to straighten.

Trigger Finger most commonly affects:

• Thumb (Trigger Thumb)
• Ring Finger
• Middle Finger

The condition may involve one or multiple fingers and can occur in one or both hands.

Trigger Finger is commonly associated with repetitive gripping activities, diabetes, rheumatoid arthritis, and occupations requiring repeated hand use. Early treatment can prevent worsening of symptoms and avoid long-term stiffness.

At Magnum Physiotherapy, our hand rehabilitation programs focus on reducing inflammation, restoring tendon mobility, improving strength, and preventing recurrence.

Common Symptoms

• Finger locking or catching during movement
• Pain at the base of the finger or thumb
• Clicking or popping sensation
• Morning stiffness in the finger
• Tenderness over the palm
• Difficulty straightening the finger
• Finger becoming stuck in a bent position
• Swelling around the tendon
• Reduced hand function
• Weak grip strength

Causes & Risk Factors

Repetitive Activities

• Repetitive gripping
• Forceful hand use
• Repetitive manual work
• Frequent use of tools

Medical Conditions

• Diabetes Mellitus
• Rheumatoid Arthritis
• Gout
• Hypothyroidism

Other Risk Factors

• Female gender
• Age between 40–60 years
• Previous hand injuries
• Occupational overuse

Types of Trigger Finger

Trigger Thumb

Affects the thumb tendon.

Single Digit Trigger Finger

Involves one finger.

Multiple Trigger Fingers

Affects more than one finger simultaneously.

Stages of Trigger Finger

Stage 1 – Pre-Triggering

Pain and tenderness without locking.

Stage 2 – Active Triggering

Clicking or catching during movement.

Stage 3 – Passive Locking

Finger locks and requires assistance to straighten.

Stage 4 – Fixed Contracture

The finger remains permanently bent.

Diagnosis

At Magnum Physiotherapy, diagnosis is primarily based on clinical examination and functional assessment.

The evaluation may include:

• Detailed medical history
• Hand and finger examination
• Palpation of the tendon
• Assessment of finger movement
• Grip strength testing
• Functional hand assessment
• Review of ultrasound or imaging if available

This thorough evaluation helps determine the severity of the condition and guide treatment planning.

Benefits of Physiotherapy for Trigger Finger

• Reduces pain and inflammation
• Improves tendon mobility
• Restores finger movement
• Prevents stiffness and contractures
• Improves grip strength
• Enhances hand function
• Reduces recurrence risk
• Supports post-injection or post-surgical recovery
• Reduces dependence on medications
• Improves quality of life

When Is Surgery Needed?

Surgical treatment may be considered if:

• Symptoms persist despite conservative treatment
• Finger locking becomes severe
• Daily activities are significantly affected
• Fixed contracture develops

Physiotherapy after surgery is essential to restore mobility, reduce scar formation, and regain strength.
