Abstract

The fused and deformed lumbar vertebrae (L) of Thoroughbred horses were observed macroscopically. Results revealed five L in two cases, and six L in three cases. In two cases, the last two lumbar vertebrae were fused with each other. One case of the fused lumbar vertebra was observed in a horse with five L and the other in that with six L. In one case, the facet of second last lumbar vertebra was articulated with its anterior lumbar vertebra. On the other hand, four cases had the caudal border on the lateral tip of the lumbar transverse process partially overlapped with the cranial border of the following lumbar transverse process. In these cases, cranial and caudal tubers were formed on the overlapped part of the lumbar transverse process.

Key Words: fuse, deformity, lumbar vertebra, horse
