Q

What creates the contour difference in a rumor versus a croup?

A

BF, ST, and SM have ischiatic and vertebral origins giving rounded appearance (horse and pig)

whereas ruminant muscles originate entirely from ischium and give an angular appearance

Q

how does the patellar lock mechanism work

A

as the stifle extends, the patella “locks” over the resting surface

16
Q

what is the upward fixation of the patella? what does it look like?

A

refers to when the patella is in an intermittent or persistent “locked” position

fully extended stifle and tarsus

17
Q

name the stifle joints and sacs

A

femoropatellar
medial femorotibial
lateral femorotibial

18
Q

describe the locations for the equine stifle joint injections

A

between patellar l., LCL + LPL, MCL + MPL

18
Q

what are the external features of the horse pelvic limb

A

chestnut and ergot

19
Q

what are the external features of the ruminant pelvic limb

A

dewclaws

20
Q

what are the external features of the pig pelvic limb

A

paradigits (dewclaws)

21
Q

what are the external features of the sheep pelvic limb

A

interdigital sinus

22
Q

trochanteric bursitis

A

whorlbone lameness

23
Q

what are the sites for intramuscular injections

A

gluteal muscles, semitendinosus, semimembranosus

24
Q

fibrotic myopathy results from trauma to the

A

semitendinosus

25
Q

what is the treatment of fibrotic myopathy

A

medical - NSAIDs, steroids
surgical - transection of scar tissue

26
Q

what are the patellar ligaments

A

medial, middle, and lateral patellar l.

27
Q

what is caudal to the patellar ligaments

A

infrapatellar fat body

28
Q

what are the stifle ligaments located medially or laterally

A

lateral femoropatellar and collateral
medial femoropatellar and collateral

29
Q

what do the lateral and medial femoropatellar ligaments help

A

maintain patella in the trochlear groove

30
Q

why is the lateral menisci more secure

A

the meniscofemoral l. supports it

31
Q

what are the 4 structures involved in the patellar locking mechanism

A
  1. patella
  2. parapatellar fibrocartilage
  3. medial patellar l.
  4. intermediate/middle patellar l.
32
Q

what is the resting surface

A

medial trochlear ridge

33
Q

T/F: the passive stay apparatus is the patellar locking mechanism and the reciprocal apparatus

A

TRUE

34
Q

How do the synovial stifle sacs communicate

A

freely - cat, dog, ruminants, pigs
variable - horses

35
Q

which two stifle synovial sacs communicate the most in the horse

A

medial femorotibial to femoropatellar

36
Q

gonitis

A

inflammation of stifle
