A Trigger Finger ( Stenosing Tenosynovitis) is caused by inflammation involving the pulleys and tendons that flex fingers. Pulleys are a series of tunnels that tendons travel through to hold the tendon against the bone. The inflammation leads to narrowing of the pulley causing the tendon to get stuck. As it progresses, the patient feels a clicking sensation in the middle knuckle with motion This leads to difficulty in flexing or extending the finger.
Severe cases can cause the finger to be locked in a flexed or extended position. Trigger fingers are more commonly seen in patients with diabetes, rheumatoid arthritis, and gout. These symptoms can sometimes be very painful and lead to functional hand problems.
The goal of treatment is to eliminate the catch of the tendon. Surgery is recommended for patients . Surgery is an outpatient procedure that surgically opens the pulley to eliminate the catching of the tendon and allows it to glide freely. Patients experience some discomfort, tenderness and swelling after surgery. But, normal use of the hand is allowed once patient comfort permits.
