The purpose of this study is to present preoperative planning with consideration of the anatomical variations of different dog breeds, gross anatomy, preoperative radiographs and computed tomography (CT) images, ring number, ring type and ring levels, rod positions and rod number for fracture treatment using the Ilizarov method in three dogs. In all cases, preoperative radiographs of affected limb and contralateral limb, intact extremity's CT views and anatomical atlases were used for preoperative frame planning. The frame is assembled preoperatively, rehearsed and then it is applied. Preoperative radiographs and clinical findings of affected limbs are beneficial for preoperative frame planning, whilst CT views are not as they do not provide any different vision of anatomical structures for all cases. Other colleagues' and our anatomical atlases, including cross-sectional views of limbs, are satisfactory for preoperative planning. In addition, functional and cosmetical results in all three cases were determined to be very good.
