Pansement aspiratif pour gangrène sur fracture ouverte du fémur immobilisée par fixateur externe

We report a case of gangrene, which developed following an open fracture of the femur immobilized with an external fixator in a 45-year-old patient. A conventional vacuum dressing (VAC Therapy®) could not be applied with the external fixator in place. An original vacuum dressing was thus fashioned after surgical debridement. Scabs were covered with calcium alginate. The lower limb was enveloped in sterile dressings and vacuum was achieved by suction with gastric tubes under adhesive films. The dressing was redone every 48 h in a surgical setting. Antibiotic prophylaxis enabled cure of the infection. Budding appeared within two weeks enabling skin grafting. Centro-medullary nailing was undertaken on day 30 to accelerate bone healing. At three months from the trauma, the initial loss of sensitivity in the leg and foot noted at the first weight bearing required programmed disarticulation of the knee after femur and wound healing. At six months, the patient had resumed his occupational activities and was pain free. This type of dressing could be useful for tissue loss over a fracture immobilized with an external fixator. This type of assembly can easily be installed in the operating room.
