Lecture 27 - Pelvic Limb 4 Flashcards
Name the bones of the pelvic limb (proximal to distal)
pelvic girdle
femur
tibia + fibula
tarsal bones
metatarsal bones
phalanges
Name the joints of the pelvic limb and the bones belonging to each (proximal to distal)
coxofemoral - pelvic girdle + femur
stifle - patella, femur, + tibia
tarsocrural - tibia/fibula + talus/calcaneus
metatarsophalangeal
proximal interphalangeal
distal interphalangeal
where is the fetlock joint
metatarsophalangeal
where is the gaskin
crus
where is the cannon bone
metatarsus
where is the coffin bone
distal phalangeal
Who has a croup? who has a rump?
croup = horses
rump = ruminants, pigs
What creates the contour difference in a rumor versus a croup?
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
where would a ruminant hoist be applied to lift a downer cow?
hook and pin bones
how can you recognize a horse femur from an ox femur?
the horse has a pronounced 3rd trochanter
the greater trochanter has cranial and caudal parts
what is the caudal attachment of the accessory gluteal m.
cranial part of the greater trochanter
where is the trochanteric bursa found?
deep to the attachment of the accessory gluteal
what is the difference in proximal attachments of the ST and SM between species
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
what gait is seen with fibrotic myopathy
shortened stride in the cranial phase
how does the patellar lock mechanism work
as the stifle extends, the patella “locks” over the resting surface
what is the upward fixation of the patella? what does it look like?
refers to when the patella is in an intermittent or persistent “locked” position
fully extended stifle and tarsus
name the stifle joints and sacs
femoropatellar
medial femorotibial
lateral femorotibial
describe the locations for the equine stifle joint injections
between patellar l., LCL + LPL, MCL + MPL
what are the external features of the horse pelvic limb
chestnut and ergot
what are the external features of the ruminant pelvic limb
dewclaws
what are the external features of the pig pelvic limb
paradigits (dewclaws)
what are the external features of the sheep pelvic limb
interdigital sinus
trochanteric bursitis
whorlbone lameness
what are the sites for intramuscular injections
gluteal muscles, semitendinosus, semimembranosus
