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
