Trigger Finger
Definition
A trigger finger occurs when the finger either locks or catches as the finger is extended. This is due to limitation of a finger tendon that opens and closes the finger.
Mechanism of Injury
Finger tendons glide through a tunnel of tissue. When the tendon becomes inflamed it thickens, thus decreasing the gliding motion of this tendon through the tunnel. The tissue that holds the tendon may also become thickened. Thus leading to decreased space and the tendon becomes momentarily stuck as the finger is extended. This problem may progress to the finger "locking" in a bent position.
Symptoms
- Presence of a small lump
- Pain in the palm of the hand
- Swelling
- Catching or popping sensation in finger or the thumb
Physical Therapy Intervention
Rec Center Physical Therapy can be the first line of defense for those suffering from trigger finger by offering treatments that can assist in decreasing inflammation in the area, increase range of motion, prescribing range of motion exercises, and patient education regarding prevention, post-surgical rehabilitation. Splint fabrication can be performed in physical therapy.
