Trigger finger (plastic surgery)

What is trigger finger?

The flexor tendons of our fingers move through a narrow tunnel that allows them to function properly. Sometimes there is less space in this tunnel, making movement more difficult. This can have several causes.

Because of this narrowing, the tendon moves less smoothly and inflammation develops. The tendon becomes thicker and a small, palpable lumps forms at the entrance of the tunnel. As this lump increases in size, the finger may start to catch or even become stuck.

Symptoms

The followig symptoms may occur:

• A finger that 'locks' when you try to straighten it
• Pain in the palm of the hand or at the level of the joint at the base of the finger

How is a trigger finger treated?

There are several ways to treat trigger finger, depending on the stage of the condition.

Taking some rest may help, allowing the inflammation around the tendon to subside. Less inflammation means less swelling and therefore more freedom of movement.

If rest alone is not sufficient to relieve the symptoms, an injection of corticosteroids may help. This injection reduces the swelling around the tendon.

In some cases, surgery is required. During this procedure, more space is created so the tendon can move freely again.
