title: Acute Hemorrhagic Flexor Tenosynovitis due to Vincula Injury.
abstract: A 20-year-old previously well woman presented to the emergency department with classical signs of acute flexor tenosynovitis, 4 hours after a minor puncture wound over the volar aspect of her right middle finger distal interphalangeal joint. Exploration of the flexor sheath in theatre revealed frank blood within the sheath and extension of the puncture wound through the profundus tendon into the short vincula beneath. The blood was irrigated from the sheath, and the patient made a complete recovery by 2 weeks postoperatively. Although rare, irritation and distension of the flexor sheath caused by vincular hemorrhage can be an alternative mechanism for the development of acute flexor tenosynovitis, and as with pyogenic flexor tenosynovitis, prompt surgical treatment can minimize the risk of long-term functional impairment.
