This research reports the case of a whippet female dog, 10 years old, with delayed union of left tibia and fibula, exposure of the fracture focus with localized infection, and extensive loss of, muscle, bone and skin after instability caused by two surgical interventions accomplished previously. A flap was made of the greater omentum in a single layer. The fracture site was reached through the subcutaneous tunnel and the coating by mesh skin grafts. The objective of this study was to evaluate the ability of the larger omentum to induce angiogenesis to the fracture site and the subsequent bone healing, considering the strong role of angiogenesis. The left tibia and fibula were stabilized with external circular fixator. After 80 days there was bone healing of the tibia around the support member and removal of the implant. Postoperative complications included partial necrosis of the cutaneous (25%) flap and shortening of the tibia with consequent laxity ligament of the member.
