“…For example, a 39° DHWA angle results in 75% of loading weight within the heels, compared to 57% loading when the angle is increased to the ‘normal’ 55° [32]. Therefore, longer shoeing/trimmer intervals which result in decreased DHWAs will increase palmar loading, resulting in the weakening and collapse of the heels, and will amplify loading of the suspensory apparatus, leading to an increased susceptibility to injury [33,34]. …”

Simple SummaryHoof shape is linked to an increased risk of lameness in the horse and has been shown to adapt to different loading patterns associated with the workload and shoeing interval length. This study investigated how different measurements of the hoof wall and the hoof pastern axis angle changed with work in riding school horses, across a four to six week shoeing/trimming interval. The dorsal hoof wall, and weight bearing and coronary band lengths reduced in size post-shoeing/trimming. This, combined with the increase to the inner and outside hoof wall heights on the digital images despite trimming, suggests that shoeing/trimming increased the vertical orientation of the hoof during the shoeing interval investigated. At the same time, increases in the dorsal hoof wall angle, heel angle, and heel height occurred, promoting a more correct dorsopalmar balance. The changes observed are consistent with the workload of the horses studied. The results suggest that a regular farriery interval of no more than six weeks could prevent excess loading of the structures within the hoof, reducing long term injury risks through cumulative, excessive loading in riding school horses.AbstractVariation in equine hoof conformation between farriery interventions lacks research, despite associations with distal limb injuries. This study aimed to determine linear and angular hoof variations pre- and post-farriery within a four to six week shoeing/trimming interval. Seventeen hoof and distal limb measurements were drawn from lateral and anterior digital photographs from 26 horses pre- and post-farriery. Most lateral view variables changed significantly. Reductions of the dorsal wall, and weight bearing and coronary band lengths resulted in an increased vertical orientation of the hoof. The increased dorsal hoof wall angle, heel angle, and heel height illustrated this further, improving dorsopalmar alignment. Mediolateral measurements of coronary band and weight bearing lengths reduced, whilst medial and lateral wall lengths from the 2D images increased, indicating an increased vertical hoof alignment. Additionally, dorsopalmar balance improved. However, the results demonstrated that a four to six week interval is sufficient for a palmer shift in the centre of pressure, increasing the loading on acutely inclined heels, altering DIP angulation, and increasing the load on susceptible structures (e.g., DDFT). Mediolateral variable asymmetries suit the lateral hoof landing and unrollment pattern of the foot during landing. The results support regular (four to six week) farriery intervals for the optimal prevention of excess loading of palmar limb structures, reducing long-term injury risks through cumulative, excessive loading.

“…The explanation for this might reside in the fact that the angle of the PIP joint causes variations in the position and direction of the distal insertion of the SDFT on the proximal aspect of the MP. Angles of tendon insertion seem to have some correlation with tendon soundness in the equine foot [20,21]. A higher leverage effect and a different torque around the MP might play a role in inducing higher tensile forces on the SDFT, thus explaining the higher incidence of lesions in the group with a smaller angle (greater hyperextension).…”

Morphometric measurements of the horses hoof -A review of the literature Healthy hooves with good quality horn and ideal hoof conformation form the basis for a healthy horse that can achieve high performance levels. Morphometric measurements of the hoof are used to survey normal hoof shape and to quantify deviations from it. They assist in identifying poor hoof conformation and in planning, implementing and controlling corrections as well as diagnosing hoof-related diseases such as laminitis. The accuracy and reproducibility of these measurements are influenced by the radiographic technique used and the procedure of taking the measurements themselves. The basis for taking measurements from radiographs of the horses hoof is a thorough preparation. Precise, consequently at the same anatomical landmark, placement of the markers and performing of the measurements is crucial. When interpreting the parameters it has to be kept in mind that they have unequal clinical relevance and statistical variability and that the breed and height of the animal significantly influence the measurements. The wider the range of normal values the more difficult it is to distinguish between normal and abnormal values. A comprehensive assessment of coherent measurements allows an accurate evaluation of the condition of the hoof. The aims of this review of literature are to describe standardised radiographic techniques, to evaluate the most important morphometric parameters regarding both their likely accuracy and clinical relevance and to give an overview of published reference values.
