Do you have a finger or thumb that catches or locks on trying to open your hand? More than likely you have a trigger finger.
Trigger finger is a common condition in both males and females over 50. Common in the diabetic patient. What happens is that the tendon gets stuck or caught under a tight A1 pulley in the palm of the hand.
- Patients present with a painful locking or catching of the finger or thumb.
- There is a tenderness in the palm at the base of the finger.
- Common in the ring finger and thumb, but all fingers can be affected.
- Moring stiffness & pain common, until the hand warms up.
Treatment is aimed at relieving the locking..
- Splints are not useful for this condition.
- A cortisone injection in the pulley system is very useful to decrease the inflammation. Particularly useful for thumb triggering and can be curative in 50 % of thumb triggers.
- Surgical treatment involves a small 1cm incision and release of the A1 pulley. This is a curative procedure.
A trigger finger is a day case procedure usually under local anaesthetic. A small 1cm incision is used to release the trigger and a dressing is applied which we change at day 3 to a small elastoplast. We encourage immediate active movement.
