Figure 1. Shown here are both feet seven years after original treatment of frostbite in the right foot, decompression of the peroneal nerve at the knee and dorsum of foot, and neurolysis of the tibial nerve in the tarsal tunnel. Note preservation of tissue in the right foot. In contrast, the left foot, subjected to the same glycemic control as the right foot, has not had surgical decompression and now has amputation of two toes and osteomyelitis of the second metatarsal head.

Figure 2. Ten years after the patient first presented with frostbite of his right foot, he developed frostbite in the right ring finger. At three months following the frostbite injury, dry gangrene is present.
