To assess the beneficial use of polypropylene mesh impregnated with vancomycin in an experimental model open fractures Gustilo IIIa in rabbits. We worked with 15 New Zeland White rabbits. All of them were carried out under general anaesthetic, a 5-cm incision longitudinal was made at the back of the right thigh. The femur was aproached and a fracture was performed with a shear, giving rise to a multifragment fracture. The wound remained open for 6 hours with the bone exposed, in a non-surgical ambient. Subsequently underwent surgical cleaning of the open fractures in two stages. The fracture was stabilized with an intramedular pin. The animals were sorted in 3 different therapeutic groups: Group 1: (5 rabbits) without other treatment. Group 2: (5 rabbits) a polypropylene mesh was placed around the fracture. Group 3: (5 rabbits) a polypropylene mesh with vancomycin was placed around the fracture. The wound was closed with nylon stiches. Three weeks postoperative, the animals were intervened surgically under general anesthesia, after aseptic cure and placement of surgical fields, femoral bone biopsies, soft tissue and mesh were taken. The rabbits were sacrified. The samples were sent to pathology and bacteriology labs.Objective
