Figure 1 Case 1, pretreatment photograph after initial debridement. The diabetic foot ulcer measuring 3 cm 3 cm on the dorsum of the left foot with exposure of muscle and tendon (Wagner grade II).

Figure 2 Case 2, pretreatment photograph before and after initial debridement. The diabetic foot ulcer measuring 2 cm 2.5 cm on the dorsum of the right foot with exposure of muscle (Wagner grade II). A: Pretreatment photograph before initial debridement; B: Pretreatment photograph after initial debridement.

Figure 3 Case 1, post-treatment photograph. After treatment with polydeoxyribonucleotide injection for 8 wk, the raw surface area was healed and epithelialized without exposure of muscles and tendons.
