Abstract

Measurements of equine hooves are token in order to assess hoof conformation, to describe changes to the hoof during disease or in relation to trimming and shoeing. Unfortunately, the terms used for the different dimensions of hoof structures differ widely. We conducted a systematic literature review with the aim of collecting terms used for hoof measurements, and to analyze the findings. Our body of literature consisted of papers and recommended reference books, written in both English and in German over the past 10 years. More than 600 scientific papers were found using the search string "TITLE-ABS-KEY ((equine OR horse) AND hoof) AND PUBYEAR \textgreater 2009 AND (LIMIT-TO (SUBJAREA, ’VETE"))" in Scopus’. Additionally, 5 handbooks were taken into account. A total of 80 Distances, 24 Angles, 34 Ratios and 16 Other measures (e.g. area of sole surface, mediolateral hoof balance) were identified. The highest number of entries (49) was recorded for the caudal angle between Pars dorsalis of the hoof and the ground line, termed often as hoof angle, dorsal hoof wall angle, or toe angle (10 English/2 German terms in total). The length of the Facies solearis, Distance between the outer extent of Pars dorsalis and dorsal cortex of Phalanx distalis; and the caudal angle between Margo solearis of Phalanx distalis and the ground line were classified as measures with highly inconsistent nomenclature (terms/entries of measure 16/25, 17/28 and 17/30, respectively). The most consistent nomenclature was recorded for the term Heel length (12/12). One should be aware of the fact that different terms might be used for the same item or that the same term might signify different measures in different publications. Established terms are not always anatomically correct. We recommend defining every used term in detail, in both written form using correct anatomical nomenclature, and in a figure. The same terms should be used in all publications of one working group. Suggestions for consistent terminology of 15 commonly used measurements in English and German are provided in the paper.
