Abstract
The fused thoracic vertebra and deformity of the lumbar vertebrae in the female Thoroughbred horse were observed macroscopically. The 11th and 12th thoracic vertebrae (T) were partially fused. They were composed of three parts between the spinous process of the 11th and 12th T, left and right caudal articular processes of the 11th T, and left and right cranial articular processes of the 12th T. The vertical surface of cranial articular process of the 11th T and left mamillary process of the 12th T were absent. The left caudal part of the transverse process of the 12th T and left costal fovea of the transverse process of the 12th T were severely deformed. On the other hand, the left transverse process of the first lumbar vertebra (L) was a typical rib-like transverse process and two times longer than the right transverse process of the 2nd L. The right transverse process of 4th L has an oval concave facet on the medial part of caudal border for articulation with the right transverse process of 5th L; the latter has a corresponding convex facet on the medial part of the cranial border in the right transverse process of the 5th L.
