Skin flap-like wounds are common in emergency trauma.However,relevant research papers are rarely reported of the definition,classification and their repair methods.A flap-like wound refers to the discontinuity and damage of the structure of superficial soft tissue caused by oblique external forces,with the appearance that one side of the tissue connected to the base of the wound by a pedicle and the rest sides detached,which is similar to a local skin flap designed in general plastic surgery.Depending on the shapes,flap-like wounds can be subdivided into triangleflap-like wounds,U-shaped flap-like woundsand irregularflap-like wounds.Besides,they can be divided into reverse flap-like wounds and anterograde flap-like wounds according to the direction of blood supply of the flaps.And in accordance with the cause of the wounds,flap-like wounds are composed of incised flap-like wounds,contused flap-like wounds and lacerated flap-like wounds.Most flap-like wounds are irregular in shape with tenuous perfusion.These flaps of wounds are prone to avascular necrosis if debrided and sutured simply,and the scar hyperplasia and contracture of the wound surfaces will not avoid affecting patientsappearance.In this work we expound the definition of common flap-like wounds and their repair methods systematically.
