B
where is the extensor fossa?
below 1d
name 4 causes of pathological mineralisation in/ around the stifle joint
Pathological mineralized or calcified bodies found in
or around the stifle joint can include avulsion fragments
of the cruciate ligaments, the long digital extensor
tendon, the gastrocnemius or popliteus muscles, fragmented
sesamoids, joint mice associated with OCD
or osteoarthrosis, meniscal mineralization or synovial
osteochondromatosis
approximately how many cranial cruciate ligament ruptures did ultrasound detect in a study on cadavers?
a) 1-11%
b) 14-20%
c) 25-34%
d) 68-79%
B- low
closure of the tibial tuberosity growth plate in dogs
a) 9-10 mo
b) 10-12 mo
c)12-15 mo
d) 3-5 mo
10-12 mo. (9-10 in cats)
9-10 tibial plateau
distal physis of tibia 12-15 mo
medial malleolus 3-5 mo
a) long digital extensor avulsion
b) normal
c) avulsion gastrocnemius
d) popliteal avulsion
C. lateral fabellae often slightly higher than medial?
a) long digital extensor avulsion
b) normal
c) avulsion gastrocnemius
d) popliteal avulsion
A. quite lateral
the infrapatellar fat pad is…
a) intrasynovial
b) intracapsular, extrasynovial
c) extracapsular
B
millers- in the fibrous layer
imaios between the fibrous and synovial layers.
a) fabellopatella ligament
b) femoropatellar ligament
c) collateropatellar ligament
B
which is not associated with traumatic luxation of the stifle
a) usually cruciate ligament damage
b) usually damage to at least one meniscus
c) usually collateral ligament damage
d) usually rupture of the joint capsule and the infrapatellar fat pad
D
where does the CCL attach to the tibia
apx red circle can be site of enthesophytes
which disease is often found concurrently with CCLR due to degenerate disease?
a) lateral meniscal tear
b) patella ligament injury
c) medial meniscal tear
d) collateral ligament rupture
C, can occur late on and be a cause of increased or persistent stifle effusion.
what imaging findings are not found in dogs with patella luxation
a) coxa valga
b) medial deviation of the tibia
c) lateral bowing of the distal femur
d) shallow trochlear groove
A- coxa vara is found. also retroversion of the femoral head and neck can be seen. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. MPL is most common.
