Spondylosis (Image sourced from Bristol Biomed Image Archive with permission)
  • Often in bulls and dogs, occurs also in horses, cats and pigs
  • 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:
  • 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


Cranial cruciate ligament rupture

  • Autoantibodies against collagens seen in the joint fluid – no relationship to the disease (ie: not an autoimmune disease) – can be seen in any joint disease


Steroid arthropathy

  • From glucocorticoids injected into joint as antiinflammatories
  • Injection sometimes causes rapid progression of degeneration
  • Glucocortyicois suppress anabolic effect of chondrocytes -> reduction of cartilage matrix syhthesis -> proteoglycan depletion -> slower repair
