VI. MUSCULO-SKELETAL SYSTEM Flashcards
most acutely dangerous among the three predisposing causes
Trauma or injury
Contact points on the hind limb
interference
4 examples/ types of interference (hint: BSOD)
Brushing,
Scalping,
Over-reaching/ Grabbing,
Diagonal
also termed as ringbone
Distal and Proximal Interphalangeal Joint
Disease
high ringbone
PIP (proximal interphalangeal joint) or pastern joint
Low ringbone
DIP (distal interphalangeal pastern joint) or coffin joint
low ringbone is more common in (hindlimb vs forelimb)
hindlimb
high ringbone is more common in (hindlimb vs forelimb)
forelimb
Most commonly used and most readily available drug for horses
Phenylbutazone
injection approach to the coffin joint
intraarticular injection
injection approach to the DIP joint
Dorsal parallel approach
injection approach to the PIP joint
Dorsolateral approach
which is more mobile: coffin joint VS pastern joint
coffin joint
inflammation of the connective tissue that surrounds the cannon bone (between the fetlock joint and the carpus) and the fetlock joint
Osselets
real and proper term for osselets
Synovitis and Capsulitis
term used if localized in the fetlock
METACARPO-(METATARSO) PHALANGEAL
JOINT DZ
METACARPO-(METATARSO) PHALANGEAL
JOINT DZ is also termed as (2 answers)
- little bone
- racehorse ankle
3 Specific causes of osselets
- articular fractures
- osteochondrosis
- trauma, injury, luxation of joint
Degenerative Joint Disease is also termed as
osteoarthritis
Progressive physical and biochemical damage to articular cartilage and subchondral bone accompanied by non-septic inflammation of the synovial membrane and joint capsule
Osteoarthritis/ DJD
DJD is septic or nonseptic?
nonseptic
main imaging of choice in cases of DJD
X-ray
Osteoarthritis/ DJD is (chronic vs. acute)
chronic
Hallmark of DJD
Articular cartilage degeneration
lameness is usually (acute vs chronic)
chronic
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
2 Preferred joint spaces where the needle
should enter
- stifle joint
- hock joint
One of the sesamoid bones commonly fractured
Distal sesamoid bones (aka Navicular bone)
6 fractures that can happen to sesamoid bones: (hint: AMABAC)
Apex
Midbody
Abaxial
Base
Axial
Comminuted
a sesamoid fracture where vascular supply is compromised
Comminuted
comminuted fracture is sometimes accompanied by what fracture
condylar fracture
sesamoid bone fractures are common in (forelimb VS hindlimb)
forelimbs –> carries more weight
more common term for tendonitis in horses
Bowed tendon
tendon that is mostly affected by tendonitis
Superficial digital flexor tendon (SDFT)
more severe pain is associated in (acute or chronic) cases
acute
poor bandaging predisposes horses to
bowed tendon
inflammation of what tendon is more severe? (SDFT vs DDFT)
Deep digital flexor tendon (DDFT)
One of the oldest diseases or conditions in the
horse
EXERTIONAL RHABDOMYOLYSIS
EXERTIONAL RHABDOMYOLYSIS is also termed as (hint: ATPEM)
- Azoturia
- Tying up
- Paralytic myoglobinuria
- Exertional myopathy
- Monday morning diseases
Monday morning disease was found primarily in ___ horses
draft
T/F: fillies (2-3 y/o) are more at risk of EXERTIONAL RHABDOMYOLYSIS
T
deficiency of these minerals causes EXERTIONAL RHABDOMYOLYSIS (2 answers)
Vit. E and Se
which recovers longer: AST vs CK
AST
2 types of chronic tying-up
- Recurrent Exertional Rhabdomyolysis (RER)
- Polysaccharide Storage Myopathy (PSSM)
This gene is responsible sa polysaccharide metabolism/use
Glycogen synthase 1 gene
type of chronic tying-up: Due to a Mutation in GYS1 gene
Polysaccharide Storage Myopathy (PSSM)
club-footed horse usually have a problem on which tendon?
Deep digital flexor tendon (DDFT)
Founder or sinking of coffin bone
laminitis
