Lesions of the sole and frog, in some cases severe and even with destruction of said regions. According to radiographic data the following lesions were identified: podal osteitis (100%); bone destruction and reabsorption of lhe third phalanx (88,23%) each. Conclusions: Despite of the severely of the lesions, there was no correlation between the clinical and radiographic findings.
