Objective: thigh lower 1/ 3 , calf, ankle and foot soft tissue defects are more common , often accompanied by bone , tendons and exposed internal fixation , clinical treatment is one of the difficulties , which require flap repair . Our predecessors on the calf vascular microdissection , angiography and medial leg flap basic and clinical research , based on extensive literature , and further improved calf fasciocutaneous flap design , so that the cut is more medial leg flap for a simple , more flexible rotation , expanding the scope of the rehabilitation , the maximum saving limb function. Method: Flap Design: In tibial condyle to the trailing edge of the medial malleolus line connection as the axis , the axis can be online at any point for the fascia rotation point , the pedicle width 2-4cm, can be antegrade or retrograde transfers. The flap range: proximal to the tibial condyle plane , plane distal to the ankle , calf before and after no more than two sides of the midline . In the deep fascia of the deep surface separation flap , do not expose the posterior tibial artery and its cutaneous branches . Press the skin defect area after the cut flap sutured to the wound . Results: The patients were 24 cases , of which nine cases anterograde , retrograde 15 cases ; cut range Max 35 × 15cm, minimum 3 × 5cm. After which 21 flaps survived completely heal a wound ; 2 cases of infection, the anti-infection , dressing healed after treatment ; 1 case distal portion of the flap necrosis, by dressing , skin graft after healing. Followed up for 4 ~ 20 months, the appearance and function satisfied. Conclusions : The modified calf fasciocutaneous flap cut is simple, flexible rotation point , expanding the scope of repair .
