This results in locking of a finger when trying to straighten it. It usually follows tight clenching of a fist.
The problem is due to a tight pulley or localized tendon thickening which results in a sudden arrest in the movement of the tendon. The tendon may slip through with some difficulty and discomfort if one forces the finger straight.
Surgery is minor and very successful and results in freeing of the obstruction thus allowing normal free movement of the finger.
Surgery is performed as a day procedure and the patient returns to normal activity 7 -10 days later.
