Morel-lavallée lesion closed legs, site and etiology rare trauma

Background: The Morel-Lavallée Injury (MLI) is a closed soft tissue injury as a result of an abrupt separation of the skin and subcutaneous tissue from the underlying fascia degloving. Clinically this lesion is presented as a long and painful injury to the affected part with soft tissue swelling and fluctuation. Clinical case: Male of 37 years-old, who suffered accident by crushing multiple dermoabrasives injuries drag and edema of both lower extremities without bone fractures, four months after he underwent a needle puncture in the left leg obtaining liquid 1400 ml, practiced 3 times the same procedure with reduced liquid each time. Ultrasound liquid is observed in the affected area septate on the inner side of the leg. Discussion: The MLI is presented to one debonding or avulsion of the skin by the tangential mechanism of injury where a shearing damage to hemolinphatic contribution of the tissues around the muscle fascia occurs,which favors filling with hematic fluid, lymphatic , liquefied fat and debris. All this is surrounded by granulation tissue, a fibrotic organizing pseudocapsule or capsule that prevents reabsorption of liquid; this explains the late onset of MLI. The current treatment of this disease is variable and depends according to the time of diagnosis. Surgical management should be reserved for recalcitrant lesions where aspiration and compression have not been successful.
