- Sudden
- Varying severity
- Acute injuries:
- Sprains
- Minor - resolved without any consequences
- More severe may result in persistent capsular and ligament laxity -> degenerative arthrosis -> impaired function
- Subluxations
- Luxations
- Intra-articular fractures
- Fracture healing may cause discontinuity of the articular surfaces
- Puncture wounds to foot may allow infection to travel to joints, bursae and tendon sheaths
- Haemorrhage into joint
- May occur in animals with clotting defects without special trauma
- Usually polyaricular
- Recurrent
- May cause pitting of articular surfaces -> degenerative arthrosis
- May occur in animals with clotting defects without special trauma
- Sprains
