Case representation of the mTTT group. A 43‐year‐old woman with a 10‐year history of diabetes suffered from a diabetic foot ulcer on the fifth toe of her left foot for 6 weeks. The wound was ulcerated and infected. Conservative treatment was ineffective after dressing change and debridement. Admission examination revealed an infectious ulcer of the fifth toe of the left foot accompanied by gangrene. The abscess cavity spread to the fifth metatarsophalangeal joint, accompanied by progressive necrosis of the distal fifth phalanx. The secretions from the wound were thick and foul‐smelling, and the cortical bone was necrotic and had sloughed off. (A–C) The appearance of the ulcer surface before operation; (D) The appearance of the wound after debridement and amputation; (E, F) The appearance of the wound after debridement and dressing change combined with VAC drainage for 6 weeks; (G, H): The wound was completely healed at 19 weeks postoperatively
