| − | *[[Musculoskeletal Terminology - Pathology|Osteophyte]] formation on ventral aspect of vertebrae
| |
| − | **Often around lumbar region
| |
| − | **Adjacent to intervertebral spaces
| |
| − | **Varies in size - small spurs -> 'bridges' between vertebrae
| |
| − | **May extend over few vertebrae
| |
| − | *Pathogenesis:
| |
| − | **Repeated abnormal movement between joints -> stress
| |
| − | ** -> Degeneration of [[Joints - Anatomy & Physiology#Fibrocartilagenous joints|''annulus fibrosis'']]
| |
| − | ** -> [[Musculoskeletal Terminology - Pathology|Osteophyte]] formation
| |
| − | *In dogs usually no symptoms
| |
| − | *In bulls may cause inability to mount
| |
| − | *In severe cases repeated damage may progress to recurrent posterior weakness and ataxia in conjuction with fractures of spondylitic and vertebral bone

| |
| − | *Glucocortyicois suppress anabolic effect of chondrocytes -> reduction of cartilage matrix syhthesis -> proteoglycan depletion -> slower repair
