It's known for long time hat the human omento can promote angiogenic activity in adjacent structures in which it is applied. In veterinary medicine, there is little research with greater omentum flap as angiogenic and immunogenic inductor, however, their adhesion properties and drainage are well known. This study wondered whether if the greater omentum can be used as angiogenic inductor in bone fractures, and therefore increase osteogenenic rates and decreasing bone infection. Initially it was designed an experimental study which aimed to obtain a greater omentum pedicle flap and conduct it so long as possible through a subcutaneous defect in order to reach long bones (femur, tibia, humerus, radius/ulna). For the experiment it was used 30 dogs cadavers of all breeds, except condrosdistrophics breeds. The results were conclusive and confirmed the possibility of reaching the omentum flap for long bones. All the animals had reached the distal half of the evaluated bones. Results were satisfactorily accomplished and in 100% of the cases the flap reached the distal half of the evaluated bones. The averages of the different flap length were: 30.87cm when double layer was used; 54.37cm in simple layer; and 92.7cm when the flap was built in L. The maximum length of the omentum has secured the possibility of reaching the distal metaphases of all the bones studied. The average length exceeded 29.87cm to femur, 20.73cm to tibia/fibula, 25.13cm to humerus, and 16.27cm to radius/ulna. The flap length variety statistically evaluated showed moderate positive correlation on the presented individuals. It was concluded that the omentum pedicle flap can be taken through the subcutaneous defect until the distal metaphase of the long bones of dogs cadavers without tension. Animals with high corporal weight have the biggest L flap length.
