Trigger finger happens when the pulley at the base of the finger becomes to thick and constricts the tendon. This makes it hard of the tendon to glide through the pulley. Because of the increased resistance to the gliding of the tendon through the pulley, one may feel pain, popping, or a catching feeling in the finger or thumb.
What causes trigger finger?
Causes for this condition are not always clear. Some trigger fingers are associated with medical conditions such as rheumatoid arthritis, gout, and diabetes. Local trauma to the palm/base of the finger may be a factor on occasion, but in most cases there is not a clear cause.
Signs and symptoms of trigger finger
- Discomfort felt at the base of the finger or thumb
- Area is often tender to local pressure
- A nodule may sometimes be found
- Finger begins to trigger or lock
Treatment of trigger finger
There are various treatments to relieve the catching or locking of the finger or thumb. Swelling of the tendon sheath can sometimes be reduced by wearing a splint or taking oral anti-inflammatory medication, as well as changing activities that may exacerbate the condition. An injection of steroids into the area around the tendon and pulley is often effective in relieving the trigger finger or thumb.
If non-surgical of treatment are unsuccessful at relieving the symptoms, surgery may be needed. This surgery is performed as an outpatient in the office, usually with simple local anesthesia. Active motion of the finger generally begins immediately after surgery. Normal use of the hand can usually be resumed once comfort permits.
