Figure 1b.

Right toe frostbite in a 55-year-old man. (a) Initial dorsoplantar radiograph shows soft-tissue irregularities of the first, second, and fifth toes without underlying bone changes. (b) Dorsoplantar radiograph obtained 4 months later at follow-up shows progression of the first and second toe soft-tissue defects and a new periarticular erosion of the distal first proximal phalanx (black arrowhead). Note the interval healing of the soft tissue of the fifth toe, with new subtle osteopenia of the fifth distal phalanx (white arrowhead).
