[Examination the extent of flap rotation from the medial head of the gastrocnemius muscle].

The authors evaluated various methods of range lengthening of muscular and cutaneous--muscular flaps from the medial head of the gastrocnemius muscle on 18 amputated lower extremities and section specimens. It has been found that lengthening of flaps size by Cheng and transformation of the muscular and cutaneous--muscular flap into the island flap produced marked lengthening of flap arch. The authors believe that incisions of the perimysium can not be recommended as a method of lengthening of flaps range.
