[Isolated rupture of the vinculum longum superficiale (V1) following blunt trauma]

The anatomy and topography of the vincula are described. Their role in the blood supply to the flexor tendons is reviewed in the light of current reports. The authors present the case history of a 59-year old patient with blunt trauma to the middle finger of the right hand. This patient suffered from severe pain in the area of the proximal phalanx and the PIP joint of the third finger, as well as from reduced extension with a deficit of 20 degrees in the PIP joint. The differential diagnosis and clinical picture are discussed. The operative findings suggest a rare instance of detachment or rupture of the vinculum of the intact superficial flexor tendon.
