Skeletal (W3.5.2) Flashcards
Medial collateral ligament
stron stabilizer
Lateral collateral ligament
stabilizer
Cranial Cruciate Ligament
inserts cranial on tibia, prevents cranial movement
Caudal Cruciate Ligament
inserts caudally on tibia, prevents caudal movement
Cranial Drawer
Cruciate tear
TPLO
Tibial Plateau Leveling Osteotomy
TTA
Tibial Tuberosity Advacement
Medial Patellar Luxation
Horse Stifle
three patellar ligaments (horse and cow) (lateral, middle, medial)
Stay apparatus
patella over medial ridge of femoral trochlea
upward fixation of the patella (horse)
Tibia
medial
Fibula
lateral
Interosseous space
separates tibia and fibula
not fused in cat and dog
Bovine tibia/fibula
Head of fibula fuses to tiba proximal
Distal end of fibula = lateral malleolus is separate from tibia
Equine tibia/fibula
Fibula reduced and only goes halfway doqn tibia
distal end of fibula = lateral malleolus is fused with tibia
Tarsus
Hock, distal row is numbered
compound hinge joint, flexion and extension
medial and lateral collateral ligaments = either side of tarsus
Talus
largest bon, medial
Calcaneous
lateral tarsus
Calcanean tuberosity
lever arm for common calcanean tendon
Osteochondrosis dissecans
OCD, #2 hock problem
fast growing cartilage outgrows nutritional supply, necrosis occurs and possible cartilage flap
Bone Spavin
osteoarthritis of distal tarsal joints, #1 problem in hock
lameness in standardbreds, western horses and jumpers
Capped hock
SQ bursa at point of hock
Sickle hocked
tarsus angled from the side
Cow hocked
tarsus deviate medially
Visceral Skeleton
Os penis
(dog/cat) bone in penis
Urinary Calculi
stones can lodge in the urethra as it narrows in the groove of the os penis
