One hindlimb from each foal was perfused arterially with barium, and the CTB and TIII were examined with micro\u2010CT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Perfusion yielded partial information from 41% of the animals. The CTB and TIII were supplied by nutrient arteries and perichondrial vessels with vertical, transverse and circumferential configurations. Fourteen of the 23 (61%) animals had focal defects in the ossification front, that is, radiological osteochondrosis. The majority of lesions matched the configuration and development of vertical vessels. Additionally, full\u2010thickness, cylindrical defects matched transverse vessels, and the long axes of some dorsal lesions matched circumferential vessels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main limitations<\/jats:title>\n                    <jats:p>Lack of histological validation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Post\u2010mortem perfusion was poor for examination of the blood supply to the growth cartilage of the CTB and TIII.
