Abstract

The aim of this study was to estimate the possibility of the effects of omental pedicle flap on improving the transverse and oblique rib fracture healing. Twenty two old dogs were used in this study. The animals were divided into two equal groups. In first group transverse rib fracture was induced, while in second group obliquely fracture induced. Each group were divided into two equal subgroups depending on covering by omental pedicle flap (treated) or without covering (control). Atropine sulphate 0.04 mg/kg B.W as a premedication followed 15 minutes later by a mixture of ketamine hydrochloride and xylazine hydrochloride 15 mg, 5 mg/kg B.W. intramuscular respectively as a general anesthesia. The histopathological study at a period of 1, 2, 3 and 4 weeks post-operation were revealed that in first group, the simple compact bone formation at 4 week in treated cases, when compared with the very simple formation of compact bone in control cases. While in second group simple compact bone formation appear at 3 week in treated cases, while compact bone was seen at 4 week in control cases. The radiological findings of the two main gruops were coincide with the histopathological results, which appeared that the degree of healing in second group better than in first group specially in treated cases.
