Abstract / Zusammenfassung

The plantar angle describes how the position of the third phalanx relates to the solar surface of the hind foot. A negative plantar angle has been linked to pathological conditions causing lameness in the hindlimb and is therefore undesirable in horses. The plantar angle is commonly determined based on latero-medial radiographs of the toe. However, as radiography is not always available in practice an additional method is frequently utilized by veterinarians and farriers in order to estimate whether a horse might present with a negative plantar angle. Using this method, a line is drawn along the coronary band of the hindlimb and extended cranially towards the forelimb on the same side of the horse. In case this line crosses the corresponding forelimb at the level or above the carpus or at the level or above the elbow, a negative plantar angle is suspected. For this study, lateral-view photographs of 140 horses of different age, height, sex and breed as well as latero-medial radiographs of their right hind foot were obtained. To test the repeatability and viability of the described method, three blinded observers determined the plantar angle of the right hind foot based on the radiographs as well as the photographs where the extended coronary line was inserted. Multifactorial regression analysis was additionally performed to identify correlations between the horses’ age, sex, breed and height at the withers as well as the coronet angle and the plantar angle in the studied horse population. A negative plantar angle was detected radiographically in 27 of the 140 horses examined. It was not possible to establish a correlation between the intersection of the extended coronary line with the carpus or the forearm and a negative plantar angle in the hind foot. Horses where the extended coronary line crossed the corresponding forelimb at the level or above the elbow joint were more likely to have a negative plantar angle. However, as this was only the case in 3 out of 140 horses, the association remains questionable. There was no influence of gender and age, but the size of the horse and the coronet angle, both showed a negative correlation with the plantar angle. The larger the horse or the horse’s coronet angle, the smaller was the plantar angle. Due to the size of the horse, the breed correlated indirectly with the plantar angle. The method of using the crossing point of the extended coronary line with the ipsilateral forelimb did not prove to be sufficiently repeatable or reliable for the detection of a negative plantar angle in the hind feet of horses in this study. Taking latero-medial radiographs of the horse’s toes remains the only way to accurately assess the position of the third phalanx within the horn capsule to date.
