WHAT IS TRIGGER FINGER / THUMB?
Trigger finger or trigger thumb is a very common condition. It is a painful (or sometimes painless) snapping or locking of the fingers or thumb. This occurs when the sheath around the tendon gets too tight and prevents the tendon from gliding smoothly with use. Picture fishing line getting hung up as it passes through the rings on a fishing rod.
CAUSES
There are many potential causes of trigger finger, but in most cases the direct cause is unknown. Some issues that have been associated with trigger finger include:
· Overuse, repetitive activities
· Inflammatory diseases (rheumatoid, gout)
· Diabetes
IS THERE A TEST FOR TRIGGER FINGER?
We can usually make the diagnosis of trigger finger simply by discussing your symptoms and medical history and examining your hand. Rarely are additional studies like an MRI needed.
SIGNS AND SYMPTOMS
Trigger finger often starts with a soreness and swelling at the base of the finger in the palm. Over time, this may progress to clicking, or even locking up of the finger after making a fist. Occasionally there is bothersome clicking or locking without ever having pain.
TREATMENT
Many cases of trigger finger will resolve with nonoperative treatment. Nonoperative treatment options include:
· Activity modification recommendations
· Anti-inflammatory medication
· Night-time splinting
· Steroid injection
Operative treatment:
When symptoms are severe or long-standing and have failed nonoperative treatment, a simple surgical procedure can often significantly improve the symptoms of trigger finger. Local numbing with or without sedation is performed and a small incision is made in the palm at the base of the affected finger. The tight sheath around the tendon is loosened so that the tendon no longer catches.
