RESUMEN
Objective To study the effect of anterolateral calf flap with extra-territorial blood supply in repairing large area of foot skin tissue injury. Methods 40 cases of arge area of foot skin tissue injury were divided into the observation group which were given anterolateral crural flap transplantation and the control group which were given anterolateral thigh flap transplantation. The wound healing condition and walking ability were observed. Results The level of wound healing, Holden walking ability and FAC walking ability were better than control group (P<0. 05). In the observation group, wound healing time was (15. 2 ± 6. 2) d and donor skin crusting time was (9. 4 ± 1. 5) d, which were less than the control group(P<0. 05). Conclusion Anterolateral calf flap with extra-territorial blood supply has positive clinical value as it can improve wound healing and walking function.
