HOW HOOF ANGLE AFFECTS BLOOD FLOW

At a positive 15-degree dynamic podoblock angle, there is increased loading of the heels and subsequently less blood flow in the bulbar vessels of this sound, sub-clinical, and low-risk laminitis horse. At a zero-degree dynamic podobock angle, blood flow is fairly balanced and the vascular bed is close to normal. At a negative 15-degree dynamic podoblock angle, there is increased loading of the toe and subsequently less blood flow in the coronary plexus and dorsal laminar vessels.
