Right hallux amputation with necrotic tissue debridement and neurovascular tendon exploration under spinal anesthesia. (a) Bone necrosis of the distal hallux and a dim color were observed during surgery; (b) Complete disruption of the distal hallux phalanx bone, insufficient blood supply to the proximal phalanx bone and dim color of the phalanx bone; (c) Disruption of the proximal phalanx bone along the articular surface of metatarsophalangeal bone, removal of distal metatarsal joint surface, and presence of purulent secretion into the plantar lacuna; (d) Debridement of the necrotic tissue to the fresh wound surface, small incision drainage on the plantar surface.
