ABSTRACT This study was carried out on 27 adult male mongrel dogs. These dogs were subjected to an artificial induction of fractures including the long bone of the pectoral limb. The induced fractures were managed surgically via different fixation techniques. The obtained results were evaluated clinically and radiographically. The present study recommended the use of Intramedullary pinning for humeral shaft fractures because it gave very promising results with minimal complications in terms of rapid return to full limb function, rigid stability at the fracture site and cortical union. While Transkeletal unilateral external fixation is the best method for radial shaft fractures. Bone plating gave also good results in treatment of radial and metacarpal fractures (3rd and 4th metacarpal bones). Key words: Pectoral limb, fractures, fixation methods, healing evaluation.
