Trigger finger, also known as stenosing tenosynovitis, is a condition that affects the tendons responsible for flexing the fingers and thumb. Let’s explore the details:

1. Symptoms:

   • Finger Locking or Catching: You’ll experience a sensation of your finger getting stuck in a bent position. This occurs because the affected tendon isn’t moving smoothly within its protective sheath.

   • Pain and Stiffness: The fingers and thumb may become painful and stiff.

   • Tenderness: You might notice tenderness in the palm near the last skin crease.

2. Causes and Mechanism:

   • Tendon Sheath Irritation: Trigger finger occurs when the tendon sheath (a protective covering around the tendon) becomes swollen or thickened.

   • Restricted Movement: The irritated sheath restricts the smooth gliding of the tendon, leading to the characteristic catching or locking sensation.

3. Risk Factors:

   • Age and Gender: It’s more common in women over the age of 50.

   • Underlying Conditions: People with diabetes, low thyroid function, or rheumatoid arthritis are at higher risk.

4. Treatment Options:

   • Splinting: Immobilizing the affected finger with a splint can help reduce irritation.

   • Steroid Injections: Corticosteroid injections into the tendon sheath can reduce swelling and improve movement.

   • Surgery: In severe cases, a surgical procedure called percutaneous release or small incisions may be necessary to free the tendon.

   • Therapy: Heat or cold therapy and gentle exercises can maintain finger mobility.

Remember, early intervention and proper management can alleviate trigger finger symptoms effectively. you can contact Dr. Chinmoy Rpy at Rajarhat Pain Clinic for proper management of Trigger Finger.
