• Abstract: Degenerative intervertebral disc disease is a common condition in dogs. There are two types of degeneration, chondroid and fibroid. Respectively, these two types of degeneration cause two distinct types of disc disease, Hansen type I disc extrusion and Hansen type II disc protrusion. In general, extrusion symptoms come on quickly, whereas protrusion typically causes chronic symptoms. Neurological impairments are caused by extradural compression of the spinal cord. Various ligament structures adjacent to the intervertebral discs provide support that varies in different regions of the vertebral column. Being in the thoracolumbar region, the dorsal and ventral longitudinal ligaments and the intercapital ligament, the most important. Currently, the degenerative disease of the intervertebral disc is well studied with regard to the types of clinical or surgical intervention and its prognosis, but still little is known about the real anatomical importance of the stabilizing ligaments of the intervertebral discs in these cases. Therefore, taking into account the inconstancy of the stabilizing intercapital ligament in the region of the T10-11 intervertebral space, it is pertinent to develop a study relating the presence or absence of this ligament, in this intervertebral space, and a greater or lesser incidence of thoracolumbar disc herniations in dogs.
