Abstract
We report a closed rupture of the second, third and fourth annular pulleys associated with avulsion of the flexor digitorum superficialis tendon in the ring finger of a healthy, 48-year-old patient. It was caused by sudden and violent flexion of the finger and led to a serious impairment of the proximal interphalangeal joint motion, despite physiotherapy and dynamic splinting. The patient was treated surgically, 3 months after the injury, with reconstruction of the second (A2) and fourth (A4) annular pulleys and excision of the distal portion of the superficialis tendon. The final functional result was satisfactory.
