There is a clicking sound while clinching fist and pain along a finger of hand. This is a sort of spot the diagnosis for medical persons. This is a condition involving flexor tendons of fingers. There are tunnels and tendon pulleys in the fingers, made up of collagen/fibrous tissue .The tendon pulleys pass through the tunnels and work to flex the fingers while forming a fist. If the tunnels constrict or the pulleys thicken they can not pass smoothly and while passing along the deformed part it passes with a clicking sound .And hence earns the name Trigger Finger. If it progresses at one stage the pulley does not pass, so the finger can not be bent.

It may occur as a part of a collagen disease or without a specific cause. At the preliminary stage I advice the patient for physiotherapy under warm saline water. It relieves of the symptoms many a times. If not I infiltrate local steroid and lastly go for surgery to release the tendon pulley .The surgery gives immediate success. Under a local anaesthesia and skin crease incision the constricting portion is divided to release the tendon .Antibiotics and rest prescribed for some time.After removal of sutures a physiotherapy is advised.
