Degenerative Joint Disease
==
Patellar Luxation
Atlantoaxial Luxation
Temporomandibular Luxation
Calve Legg-Perthe's Disease
Degenerative Arthropathy
Joint Trauma
Nutritional diseases
Hypervitaminosis A
Disc Protrusion
Cervical Spinal Stenosis
Cervicospinal Arthropathy
Spondylosis
- 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:
- Repeated abnormal movement between joints -> stress
- -> Degeneration of annulus fibrosis
- -> 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
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
