24
Q

Hallmark of DJD

A

Articular cartilage degeneration

25
lameness is usually (acute vs chronic)
chronic
26
capsule starts thickening as a form of healing response but instead of healing properly and decrease in size, cartilage breaks off from the joint
Osteochondritis dissecans
27

Comminuted
31
comminuted fracture is sometimes accompanied by what fracture
condylar fracture
32
sesamoid bone fractures are common in (forelimb VS hindlimb)
forelimbs --> carries more weight

Bowed tendon
34
tendon that is mostly affected by tendonitis
Superficial digital flexor tendon (SDFT)
35
more severe pain is associated in (acute or chronic) cases
acute
36
poor bandaging predisposes horses to
bowed tendon
37
inflammation of what tendon is more severe? (SDFT vs DDFT)
