Ring injury with bilateral rupture of the digital arteries without skin damage.

A particular type of trauma of the ring finger, brought about by a ring, resulted in a subadventitial rupture of the radial digital artery and a complete rupture of the ulnar digital artery, despite the skin remaining intact. The radial digital artery was sutured and the ulnar digital artery was repaired by a vein graft. By the eighth month, the result was satisfactory, with a radial digital artery patent, in spite of a thrombosis of the ulnar digital artery.
