About Video

The flap is based on the septocutaneous (or musculocutaneous) perforators of the descending branch of the lateral circumflex femoral artery. An average flap size of 10 × 8 cm can be raised and the defect can be closed primarily. Large flaps with dimension of 30 × 12 cm can also be raised. A straight line from the anterior superior iliac spine to the superolateral border of the patella is marked. A circle with a radius of 3 cm is drawn at the mid-point of this line. The perforators supplying the skin are in the lower outer quadrant of the circle. The anterior incision is taken first and the perforators are identified and traced to their origin from the descending branch of the lateral circumflex femoral artery in the intermuscular septum between the vastus lateralis and rectus femoris muscle. The descending branch of the lateral circumflex femoral vessels is dissected to the origin for gaining the desired vascular pedicle length. The posterior incision is then taken and the flap is raised in the suprafascial plane up to the entry of the perforator. A cuff of fascia is included with the flap around the perforator.
