Fig. 4

Four axial computed tomographic images of the right stifle of the same dog in Fig. 2 (GM) made at the level of the first prong of the fork. (a) immediately postoperatively, (b) 1 m postoperatively, (c) 2 months postoperatively; (d) 3 months postoperatively. Note the slow progressive increase of smooth, more homogenous mineral attenuation that becomes more well-defined on Image (d), consistent with healing. This smooth bone production tapers toward the center of the osteotomy, forming an hourglass shape, and resulting in incomplete filling of the osteotomy gap
