Trigger Finger Explained

What is Trigger Finger

Basic Trigger Finger Information

Trigger finger is a condition that causes pain, stiffness, and a sensation of locking or catching when you bend and straighten your finger. This can occur in any finger. With this condition, the A1 pulley becomes inflamed or thickened, making it harder for the flexor tendon to glide smoothly as the finger bends. While the cause of trigger finger is not well known, diabetes and rheumatoid arthritis can increase your risk of developing the condition. It can also increase your risk of developing the condition in multiple fingers.

Symptoms

Symptoms often start without a single injury. These symptoms may include:

  • A tender lump at the base of the finger on the palmar side
  • A catching, popping, or locking sensation with finger movement
  • Pain when you bend or straighten the finger

Initial Home Treatment

  • Rest
  • Exercises such as gentle stretching to straighten and bend the finger can decrease stiffness and improve range of motion
  • Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen can help relieve pain and inflammation
    • NSAID examples: Ibuprofen, Advil, Aleve
    • Acetaminophen examples: Tylenol

When to See a Doctor

  • If the locking, popping, stiffness, and pain persists after home treatment
  • If the finger becomes locked in a bent position

Nonsurgical Treatment for Trigger Finger

  • Steroid injection:
    • This may resolve the pain and triggering over a period of one day to several weeks.
    • If symptoms do not improve, a second injection may be given 6 weeks later.
    • If symptoms persist after 2 injections then surgery may be considered.

Surgical Treatment for Trigger Finger

Surgery for this condition is elective, outpatient, and is based on the patient’s degree of pain or loss of function.

  • The surgical procedure is called a “tenolysis” or “trigger finger release”.
  • The goal of the surgery is to release the A1 pulley that is blocking the tendon movement so the flexor tendon can glide more easily through the tendon sheath.
  • Surgery is performed in a small open incision in the palm. The A1 pulley is divided so the flexor tendon can glide freely. Although pulleys have an important function, releasing the A1 pulley should not cause problems in the future.
