Trigger Finger

Tendinitis is inflammation, irritation, and swelling of a tendon, which is the fibrous structure that joins muscle to bone. Each finger have two tendons. The tendons run along the palm side of the fingers and are very close to the surface of the skin, particularly where the skin folds as you bend your fingers. The tendons in the fingers are called flexor tendons. The longer tendon (flexor digitorum profundus attaches to the last bone of the finger and bends the tip; the shorter tendon (flexor digitorum sublimis) bends the middle joint of the finger.

Symptoms of Trigger Finger

  • An inability to bend one or more joints of the finger
  • Pain when you bend your finger
  • Mild swelling over the joint closest to your fingertip

Treatment of Trigger Finger

Initial treatment of the condition can include:

  • Icing the area
  • Avoiding activities that caused the inflammation
  • Splinting the affected finger or thumb in an extended position for 10 to 14 days

Your physician may prescribe an oral anti-inflammatory medication to reduce the pain and swelling.  In addition, to reduce the inflammation of the tendon sheath, your physician may also give you an injection of corticosteroid (cortisone-like medication) directly to the affected area.  If symptoms persist, another injection could be given in three or four weeks, except in cases of rheumatoid diseases.  Patients with rheumatoid disease are at an increased risk for tendon rupture and surgery should be considered after one injection fails to relieve the symptoms.
