Abstract：
It is important to understand the effects of hoof trimming on hoof and limb conformation to maximize its benefits on the health of the appendicular skeleton of horses, thus promoting improvements in athletic performance and sporting longevity with regard to athletic horses. There is little information on possible changes in the angulation of the thoracic limb joints after hoof trimming and correlations between the angulation of the thoracic limb joints with hoof measurements. To that purpose, nineteen Mangalarga mares received routine hoof trimming. Visual recordings (photographs) were taken before and after the procedure. Differences (p < 0.05) were found in hoof length, toe angle, heel angle, medial heel height, and metacarpophalangeal angle. Before trimming, correlations were found between frog length and scapulohumeral angle (SH) (r = -0.457; p = 0.049), and between toe length and shoulder-ground angle (SG) (r = -0.553; p = 0.049). A correlation was also seen between the distance from the frog to the lateral wall and the SH angle (r = 0.690; p = 0.001). After trimming, there was a correlation between humeroradial (HR) and SH joint angles (r = 0.669; p = 0.002), and the SG and SH angles (r = 0.488; p = 0.034). This study showed an immediate effect of trimming on the toe angle and heel angle and on the metacarpophalangeal joint angle, in addition to correlations between the hoof and proximal joint angles, following trimming, thus evidencing the relevance of trimming not only in hoof morphology, but also in the conformation of the appendicular skeleton of horses.
摘要：
重要的是要了解蹄修剪对蹄和肢体构象的影响，以最大限度地提高其对马的阑尾骨骼健康的益处，从而促进运动马的运动表现和运动寿命的改善。关于蹄修剪后胸肢体关节角度的可能变化以及胸肢体关节角度与蹄测量之间的相关性的信息很少。为此，十九只Mangalarga母马接受了例行的蹄部修剪。在手术之前和之后进行视觉记录(照片)。差异（p<0.05）发现蹄长，前束角,后跟角,鞋跟内侧高度,和掌指角。修剪前,青蛙的长度与肩周角（SH）之间存在相关性（r=-0.457；p=0.049），脚趾长度和肩地角（SG）之间（r=-0.553；p=0.049）。从青蛙到侧壁的距离与SH角之间也存在相关性（r=0.690；p=0.001）。修整后,肱骨放射（HR）和SH关节角度之间存在相关性（r=0.669；p=0.002），以及SG和SH角（r=0.488；p=0.034）。这项研究表明，修剪对脚趾角和脚跟角以及掌指关节角的直接影响，除了蹄和近端关节角度之间的相关性，修剪后，因此证明修剪的相关性不仅在蹄形态上，而且在马的附肢骨骼的构造中。
