[The simultaneous distally based sural flap. A therapeutic option for coverage of both heels].

Exposed bradytrophic tissue in regions with high mechanical loading is an indication for defect coverage with (myo-, adipo-) fasciocutaneous flaps. In this case, distally based sural flaps were used for bilateral coverage of defects in weight-bearing areas of feet after fourth-degree frostbite. Residual defects can be covered with a split skin mesh graft. The definitive prosthetic supply of the foot assumes a stabilized plantar soft tissue situation. Among its advantages in comparison to free microvascular flaps, the locally based fasciocutaneous flap can be harvested with less donor site morbidity after elevation and does not require secondary debulking. It has been shown that the reduced stability at the border zone between flap and mesh graft has an adverse effect.
