Trigger Finger
What is trigger finger?
Trigger finger affects the tendon that bends a finger or thumb. Thickening around the tendon tunnel can make the tendon catch as it moves, causing clicking, stiffness or locking.
Symptoms are often worse first thing in the morning. The finger may release with a click or may need to be straightened using the other hand. There can also be tenderness in the palm at the base of the affected finger.
When might treatment be needed?
Some mild cases settle without treatment. An assessment may be helpful if the finger is painful, repeatedly locks, stays bent, or interferes with work, hobbies or everyday tasks.
Trigger finger is more common in people with diabetes, although it often occurs without a clear underlying cause.
Treatment and recovery
Initial treatment can include avoiding activities that aggravate the pain, using a small night splint and having a steroid injection around the tendon.
If symptoms continue or the finger remains locked, a trigger finger release may be recommended. The tight roof of the tendon tunnel is divided through a small incision so the tendon can glide more freely. This is commonly performed as a day case under local anaesthetic.
Recovery and aftercare
Light use of the hand is usually encouraged soon after surgery, together with regular movement of the finger. A small dressing is normally required while the wound heals.
The clicking often settles quickly, although swelling, stiffness or scar tenderness may take several weeks to improve. Hand therapy may be recommended if movement is slow to return.
