BACKGROUND: Horses are economically and emotionally valuable animals in various activities, especially sports. Thus, paying attention to their limb's health and conformation is vital. One of the most common diseases in the limbs of horses is laminitis. Horses with this condition suffer from lameness because it affects laminar tissue. In addition to clinical signs, radiographic criteria are essential for identifying this disease.OBJECTIVES: It is predicted that examining the effectiveness of quantitative radiographic criteria of the hoof can be helpful in the diagnosis of laminitis. Therefore, in this study, five quantitatively effective factors were investigated before and after hoof trimming to determine the changes in the radiographic diagnosis of laminitis.METHODS: A total of 11 clinically healthy horses were used in the current study. Using Marco DICOM Viewer software, lateral and dorsopalmar radiographs from the hoofs of both forelimbs were evaluated for the diagnosis of laminitis using effective quantitative criteria. Using SPSS version 24, paired T-tests were used to analyze quantitative data. P≤0.05 was considered significant.RESULTS: According to the results of this study, there were no significant differences between the right and left forelimbs after hoof trimming. On the other hand, significant differences were observed in the four following criteria: dorsal thickness between the dorsal surface of the third phalanx and the dorsal surface of the hoof, the angle between the dorsal surface of the third phalanx and the dorsal surface of the hoof, sole thickness, and the ratio of the third phalanx dorsal surface thickness to its maximum length in each forelimb before and after hoof trimming.CONCLUSIONS: During the radiographic examination, the hoof should be positioned in a standard way to diagnose laminitis accurately. However, if the hoof is not trimmed or not trimmed properly, it can interfere with laminitis diagnosis.
