To study the therapeutic effect of adjacent pedicle fascia flap filling and arthrodesis in the regional management of sinus tract in diabetic foot.From February 2007 to August 2010, 6 patients suffering diabetic foot with sinus tract were included. There were 4 male and 2 female patients, aged 47 to 68 (averaging 58.3 +/- 6.7). One case had the entrance of sinus tract in the heel, and its base located deep in the calcaneus. Three cases had the sinus tract in the vola or dorsum of the foot, in which 1 with a perforating tract connecting the vola and the dorsum. Another 2 cases were in the toes, both located around joints. Under the effective treatments of anti-infection, anti-coagulation and control of blood sugar, blood pressure as well as blood lipid level, the patients were subjected to surgical treatments of sinus tract, the sinuses in the heel, sole and dorsum of the feet were filled up with facial flap, and those in the toes were eliminated using arthrodesis.All the 6 patients received rational debridement. Four patients were treated with adjacent fascia flap filling, the other two were treated with arthrodesis. The sinus tracts healed 14-20 d after surgery in all patients. One patient developed skin necrosis at the edge of the incision in the dorsum of the foot and another whose sinus located in the toe suffered inflammation and exudation. Both patients recovered after dressing replacement, antiseptic therapy and blood sugar regulation for a period of time.Appropriately designed pedicle fascia flap can provide satisfactory healing for sinus in the heel, vola and dorsum, and arthrodesis is a safe and effective way for that in the toes. Rational debridement is the key prerequisite for healing of sinus tract in diabetic foot.
