Abstract
Intervertebral disc protrusion occurs in almost all breeds of dogs. Clinical signs include pain, loss of coordination, neck stiffness, lack of apetite , paresis and/or paralyses of extremities. It appears in two separate morphological forms, as Hansen type I disc protrusion in predominantly chondrodystrophic breeds an as Hansen type II in all other. Radiological diagnostic methods include plain radiography and myelography. Other methods available are discography, epidurography, computed tomography (CT) and magnetic resonace imaging (MRI). Our study reviewed the results of plain and myelography diagnosed disc protrusion in the three year period (2009-2012). During that period, 275 dogs of different breeds were included in the study, as well as mongrel dogs which are displayed as a separate group in results. In overall, chondrodystrophic breeds were present with 66% of all cases examined, non chondrodystrophic breeds in 12% and crossbred group 22% of all cases. The breeds with most occurence of disc protrusion were Poodle, Pekingese dog and Cocker Spaniel. Intervertebral disc protrusion most often occured between T12 and T13 vertebral bodies (23%), followed by T13 and L1 (18%), L5 and L6 (14%), L1 and L2 (11%), L4 and L5 (6%), T11 and T12 (6%) and between L3 and L4 (5%). All other herniations were diagnosed in 7% of cases.
