Trigger Finger

  • What is Trigger Finger?

    Trigger Finger is pain or stiffness when straightening or bending the finger. The tendon lining is like a tunnel in which the tendons glide to bring about motion. Swelling of the tendon lining impairs the smooth gliding motion of the tendons, which causes pain or a catching feeling when you try to flex your finger, and the finger may become ‘locked’.

  • The causes of Trigger Finger are not always clear. However, they include Rheumatoid Arthritis, Gout and Diabetes. Trauma to the palm or base of the finger may also be a cause.

  • The symptoms of Trigger Finger include:

    • A nodule may be felt at the base of your finger or thumb
    • Aching sensations at the base of your finger or thumb
    • Tightness at the base of your finger or thumb
    • Triggering or locking on opening or closing the fingers — When your finger begins to trigger or lock, you are likely to feel pain in the middle of your finger or thumb

  • To start with, non-surgical methods of treatment are tried, including:

    • Non-Steroidal Anti-Inflammatory Medication
    • Reducing the frequency of times that you grip things
    • Steroid injection
    • Wearing a splint

    If the symptoms persist, surgery may be suggested. The procedure is minor and can be done as day surgery under local anaesthesia. Surgery is almost always successful, and you will regain normal use of your hand upon recovery.
