7. The groin flap: a new technique to repair traumatic tissue defects.

Tissue loss from trauma, particularly in the hand and forearm, occasionally requires immediate skin-flap coverage to ensure optimal healing. A consistently safe technique of skin-flap coverage is use of a groin flap. Anatomic studies of this flap have revealed the reliability of blood supply by the superficial circumflex iliac vessels to an area of skin and subcutaneous tissue running paralle to the inguinal ligament lateral to the femoral artery, and the axial relation of the vessels to the flap allows the surgeon to take a longer flap than usual without fear of vascular embarassment. Three case reports illustrate the value of the groin flap in primary soft-tissue closure and in the treatment of acute traumatic injuries.
