Abstract

Experimental bone defect was created at med shift of femoral bone of twelve adult stray dogs from both sexes. Operative animals were divided into two equal groups each group have 6 animals, in first group the defect induced at med shift of femoral bone only and laporotomy done to draw the omental flap through tunnel underlying the skin reaching the affected site. At the second group the defect induced directly through skin ,soft tissue and bone under imperfect surgical conditions, the omental flap withdraw as same manner of first group. Animals inspected in different periods and X rays photograph were taken at the time 7, 28 and 45 days. Animals scarified through different times (7, 21 and 45) one animal for each period to inspect the way of omental flap. The clinicopathological results were same in all groups except the signs of transite lameness and hard swelling along the site of withdrawing omentum from abdomen to the site of induced defect. The results of X-Rays examination exhibited complete bone defect healing in the first group during the fourth weeks after treatment and in different degree whereas at the second group complete healing occurs but in lesser degree than later and feature of the defect completely subside at 45 days after treatment. In conclusion the experimental bone defect which covered with omental flap that withdrawn from the abdominal cavity accelerates the healing of defected bony tissue as compare of put such flap on the defected soft and bony tissue under the same manner of experimental conditions.
