Lecture 25 - MSK Pelvic Limb 2 Flashcards
Why is it pelvic symphysis rather than pubic symphysis
it is the hyaline cartilage between the pubis and ischium, not just the pubis
what ligament is not present in the cat
sacrotuberous ligament
what is the attachment on the sacrotuberous ligament
transverse processes of S3 and Cd1 to ischiatic tuberosity
What two ligaments contribute to the coxofemoral joint
ligament of the femoral head
transverse acetabular ligament
what ligament closes the acetabulum
transverse acetabular ligament
What is NOT true about the coxofemoral joint
a. ball and socket joint
b. not very motile
c. contains an articular capsule
b. not very motile
what must rupture in a coxofemoral joint luxation
articular capsule and l. of femoral head
what is the most common displacement of coxofemoral joint luxation
craniodorsally
Describe menisci
2 in each stifle
increase joint congruence and even load distribution; decrease friction
What is the largest joint capsule in the body? How many intercommunication sacs are present?
Stifle joint; 3 sacs
What are the 3 sacs of the stifle joint?
1 medial tibial/femoral condyle sac
1 lateral tibial/femoral condyle sac
1 cranial femur (deep to patella)
Why is the concept of intercommunicating sacs important
infection, cells, blood, and medication present in one sac are likely to be in all sacs
what force does the lateral collateral ligament resist?
adduction
what force does the medial collateral ligament resist?
abduction
what do the cranial and caudal cruciate ligaments do?
limit medial rotation of the tibia
resist craniocaudal displacement
