[Clinical application of medial leg skin flap for the repair of defects of the extremities].

A total of fifteen medial leg skin flaps with the posterior tibial artery as an axial vessel have been applied successfully to reconstruct extremity defects, such as chronic ulcers, scar contracture, high-voltage electric injuries and hot crush, etc. This skin flap can be elevated as a free flap, or vascular island flap, or cross-leg vascular pedicle flap to resurface the defects on the extremities. It is especially suitable for foot repair because of its long vascular pedicle and wide rotational arc as an island skin flap. The paper describes and discusses the indications, design and operating technique of this flap.
