The Long-Term Results of Glue-on Shoes on Dorsal Hoof Wall Distortion

Abstract

Every equine hoof has a certain amount of distortion. This presents in various forms: flares, dished toes, under-run heels, and cracks. Several farrier texts anecdotally suggest a correlation between hoof capsule distortion and lameness. The goal of this study was to evaluate the effects of the Sigafoos Series I glue-on shoe on hoof capsule distortion, and specifically, the effect on dorsal wall deviation. Measurements of the hoof were made using the Metron hoof evaluating system by Eponatech. Comparisons were made of the following values: dorsal length, hoof angle, dorsal wall deviation, hairline angle, hairline deviation, heel/toe height, heel height, heel angle, and support length. The study group consisted of front feet of horses shod exclusively in the Sigafoos glue-on shoe for a period of 1 year, and the control group consisted of 133 front feet from horses using nailed on shoes for a similar period and with a musculoskeletal complaint. The results indicate a 48% reduction in dorsal wall deviation for the study group. This finding supports the use of this glue-on shoe as beneficial with the goal to reduce capsular distortion of the dorsal wall.
