Case 1. A male patient, 49 years old, was admitted to our hospital due to postoperative deformity and infection of the right foot for over 6 months. Upon admission, a large quantity of purulent secretion was noted in the medial wounds of the right foot, accompanied with sinus tract formation in the right calcaneus, stiffness, and deformity of the ankle (a). After admission, thorough debridement combined with VSD was performed (b). At one week after the VSD removal, granulation tissues surrounding the wounds grew well (c). The chimeric anterolateral thigh perforator flap was designed and harvested, and the perforator flap was thinned (d-f). The muscle flap was utilized to obliterate the dead space of calcaneal defects (g, h). The skin flap was used for wound coverage and the blood supply was excellent after vascular anastomosis (i). During postoperative, twelve months follow-up, the foot infection was effectively controlled, with esthetic appearance of the skin flap (j, k), and the weight-bearing and walking functions of the foot was restored (l)
