Figure ringavul

Figure Legend: Ring avulsion injuries may appear deceptively normal because of color from blood trapped in the digit and active range of motion maintained by the long tendons. In this example, the finger appeared viable (1), despite a long zone of tissue disruption from the distal interphalangeal joint (2) to the base of the finger (3,4,5). In fact, the finger was only attached by the flexor tendons and digital nerves (5) and was unsalvageable.
