Trigger finger (locked finger) is a common condition that affects the movement and ability to straighten your finger.
Attempting to straighten your finger can be especially painful, there may be a locking or catching feeling before the finger is straightened out. The condition is caused by inflammation of the flexor tendon in your finger. This causes the tendon to swell, which prevents it from gliding smoothly through the flexor sheath (tunnel).
Causes of trigger finger
People that are regularly involved in activities that strain their hands may be more at risk, however here are some other possible causes which may lead to developing the condition:
- Women tend to be more at risk than men
- Trigger finger is more common in people with diabetes and rheumatoid arthritis.
- Trigger finger occurs more in people aged between 40-60 years of age.
Typical symptoms include stiffness or tenderness of the finger or thumb, and a popping, clicking or catching sensation when straightening the finger. In some cases the finger or thumb becomes stuck and locks in one position which can make it extremely difficult to bend. When the tendon catches it can lead to more swelling and inflammation, which contributes to the problem, making it worse.
Some people report that triggering is worse in the morning.
Trigger Finger Treatment options
In many cases trigger finger can be treated with anti-inflammatory medication and rest. If the condition persists Corticosteroids, also known as steroids, can be injected to reduce swelling. In trigger finger cases, liquid corticosteroids are injected into the membrane that the tendon slides through, the tendon sheath, at the base of the affected finger or thumb. The injection works by reducing the swelling of the tendon, which allows the tendon to move freely again. While relief can begin to occur within a few days of having the injection, it usually takes a few weeks.
If this doesn’t resolve the problem, a simple surgical procedure can be used. Surgery for trigger finger is usually performed under local anesthetic and takes roughly 15 minutes. Most patients are then able to move their finger freely, immediately after surgery.
