Clinical Relevance Flashcards
A horse has a deep laceration across its gaskin. Between what two joints is the gaskin?
stifle and hock
A condition where the patella rides outside the femoral groove when the knee is flexed
patellar luxation
Displacement of the head of the femur outside of the acetabulum, and it is not uncommon in dogs and cats
Coxofemoral luxation
What must rupture for complete coxofemoral luxation to occur?
ligament of the head of the femur and the joint capsule must rupture.
Why is dislocation of the coxal (hip) joint is much less common in the horse?
extra femoral head ligament
Abnormal development or growth of the coxofemoral joint, usually occurring bilaterally
Hip dysplasia
CrCL rupture diagnostic test?
cranial drawer test
What may be a reason for inability to feel the femoral artery pulse?
saddle thrombus
Intramuscular injections may be performed in what region?
croup or rump region
The semitendinosus and semimembranosus mm. are a site of what?
IM injections
Fibrotic myopathy associated with what muscle?
semitendinosus m.
If the adductors are not working properly then what happens?
animal may exhibit splayed out hindlimbs and an inability to stand on slippery floors because can’t keep legs adducted
One muscle that attaches to the greater trochanter of the femur is the:
deep gluteal m.
Inflammation of the trochanter bursa is a cause of lameness in performance horses
Formal and common name?
trochanteric bursitis
Whorlbone lameness
Q3: what does femoral n. paralysis look like?
Femoral n. supplies motor innervation to the quadriceps femoris m. Femoral n. neuropathy (dysfunction) results in an animal’s inability to effectively keep its stifle extended (action of quadriceps femoris m.) and therefore it cannot normally bear weight on the affected limb.
Which muscle and its tendon is partially removed as a surgical aid to managing stringhalt?
lateral digital extensor m.
This dairy cow can not rise beyond this point and shows a ‘rabbit leg’ position of both hind limbs. The cow is unable to extend her hocks and weight bear. Rupture of what muscle in the caudal crus results in this clinical presentation?
gastrocnemius m.
What happens when the fibularis tertius is ruptured?
the tarsus can be extended while the stifle is flexed, a distinct clinical finding
Patellar locking mechanism in horse is part of the passive stay apparatus of the pelvic limb. When it is stuck in ‘lock’, it is called
‘upward fixation of the patella’ (“locking stifles”)
Two clinical observations related to tarsus of the horse?
“Thoroughpin” (tarsal tendosynovitis) and calcaneal bursitis in horses.
long plantar (ligament) desmitis equals
curb
a soft swelling in a horse’s hock that’s caused by inflammation and fluid in the joint capsule
bog spavin
Transection of lateral digital flexor tendon in proximal dorsolateral metatarsus treats
stringhalt
SDF and DDF tendonitis equals
bowed tendons
Upward fixation of the patella (UFP) equals
locked stifles
Main cause of lameness in cattle?
Foot problems
