What is Trigger Finger?

Trigger Finger (Stenosing Tenosynovitis) is a condition where a finger gets stuck in a bent position and then suddenly straightens with a snapping or popping sensation. It occurs beacause the flexor tendon which controls the finger gets inflamed and thickened, which restricts the smooth gliding of the tendon through the pulley system in the finger.

Common Causes:

Repetitive gripping or prolonged use of hands.

Swollen flexor tendon

Small lump(nodule) on the tendon

Trauma or swelling in the hand

Rheumatoid arthritis or diabetes

Unknown idiopathic causes

Risk Factors:

Repetitive Gripping: Occupation that involves more gripping activities

Health Conditions: Diabetes, Rheumatoid arthritis, Low Thyroid function

Gender: Females are more prone to Trigger Finger

Other Underlying Causes:

Peri Arthritis of Shoulder

Carpal Tunnel Syndrome

Vitamin B-6 deficiency

Symptoms:

Finger stiffness, especially in the morning

Pain and tenderness at the base of the affected finger (commonly the thumb, ring, or middle finger)

A popping or clicking sensation when moving the finger

In severe cases, the finger may become locked in a bent position which suddenly opens with a pop.

Treatment Options:

1. Conservative Management:

Rest and activity modification

Ice therapy for inflammation

Splinting to keep the finger in an extended position

Nonsteroidal anti-inflammatory drugs (NSAIDs)

2. Physiotherapy:

Gentle stretching exercises

Strengthening exercises

Soft tissue mobilization to reduce tendon adhesions

Ultrasound therapy to decrease inflammation

3. Medical Interventions:

Corticosteroid injections to reduce swelling

Percutaneous release (minimally invasive procedure)

Surgical release if conservative treatment fails
