| This study was assigned to investigate the role of autogenous pedicle flap and free graft of omentum in healing of induced oblique rib fracture in dogs. Twelve adult dogs were used weighing (15-20) Kg and were maintained under same condition then were divided into two groups .all animals subjected to oblique rib fracture in both side of thoracic chest at 4th last rib by wire saw in interval of long period. The skin over the rib opened, then blunt dissection to underlining tissue till reach the rib, once this had been achieved an oblique fracture was performed by using wire saw. Then fracture is fixed with stainless steel orthopedic wire throw drill a hole on both fracture end. In the first group omentum pedicle was extended subcutaneously after laparotomy operation in the left flank region then wrapped around the fracture and fixed with adjacent muscle over the fracture site by multiple stitches of 2.0 catgut suture. While in the second group free omentum graft was harvested then enrolled around the fracture site and fixed as the same pattern of the first group. During clinical follow-up of treatment dogs record signs of fever, cellulites, swelling at fracture site, stitch abscess in tow case, fracture overlap accrue in 2 fracture site. Biopsies were taken from the fracture site to follow-up fracture healing microscopically at 1,2,3,4th week, histopathological results of each group showed present of omentum tissue rich with blood vessels with formation of fibrous connective tissue in first group at 1st week that help to form thick regular direction of trabecular bone at 2nd week while in second group show convert fibrous connective tissue in some area to hyaline cartilage then form at 2nd week narrow irregular direction of trabecular bone. in first group at 3rd week record start well compact bone surround haversian canal and progress to more thick at 4th week, at the same period in second group show increase in thickness of trabecular bone with simple compact bone formation while at 4th week show small area of haversian canal surround by lamenated compact bone. Conclusion of this study reveals that autogenous omentum pedicels promote oblique rib fractures healing more than free graft. | ||
