What is trigger thumb/finger?
Trigger thumb is where a child finds it difficult or impossible to fully extend one of their thumbs or fingers. It is fairly uncommon in children, and is more often seen in adults.
There is a fibrous band (ligament) that sits under the thumb or finger tendon – if this is too tight, it prevents the ability for the tendon to do a gliding motion through the tendon sheath if stretched, and this causes the tendon to become inflamed.
While at first, your child may be able to extend their thumb or finger, this can be uncomfortable or painful. There might be outwardly obvious symptoms such as swelling or a clicking sound. Later on, the thumb or finger may become stuck in a flexed position and you may be able to feel a bump at the base of the thumb or finger on your child’s palm.
Usually, a physical exam is enough to provide a diagnosis and no X-rays or other investigations are needed.
Most children will not require treatment and it will get better by itself. For half of the children who experience trigger thumb or finger, by the time they turn 3 it will have gone away.
If after the age of 3 there is still a problem with the thumb or finger, then surgical treatment may be required. This will see the tendon released from the tendon sheath where it is catching, allowing it to glide more easily.
