Trigger Finger occurs when a tendon develops a knot, or swelling of the lining through which the tendon must glide in order to function. When the tendon swells, it must still squeeze through this sheath, which causes pain, popping, or a feeling that the finger is “catching” as it attempts to bend. When this occurs inflammation and additional swelling is produced. The finger may become impossible to bend or straighten.
There is no clear-cut cause for trigger finger. It can be associated with arthritis, diabetes, or other medical conditions. Initial discomfort may be felt at the base of the finger or thumb. A thickening also may be detected in the same area. The finger then begins to lock in the “trigger” position. Goals of treatment are to eliminate the locking of the finger and allow normal movement to return. Swelling must, therefore, be reduced to allow for gliding of the tendon. Anti-inflammatory medication, taken by mouth or injected into the area, may give some relief along with wearing a splint and altering activities to reduce aggravation to the area. Surgery may be recommended to open the area for the tendon to glide more freely in the sheath. There may be tenderness, discomfort and swelling following surgery, and motion therapy usually begins immediately following the same.
