Crus Joints & Structures Flashcards
Meniscus
C shaped fibrocartilage
Sacs of articular capsule
1 femoropatellar sac
2 femorotibial sacs
Patellar ligament
Tendon of quad femoris from patella to tibial tub
Femoropatellar ligaments
Medial & lateral
Thin facial bands between patella & medial/lateral fab
Femorotibial ligaments
Medial & lateral collateral ligaments
Cranial and caudal ligaments
Attahcment of cranial cruicate ligament
Between cranial intercondylar area of tibia & caudomedial part of lateral condyle of femur
Function of cranial crucitate lig
Prevents cranial sliding of tibia
Attachment of caudal cruciate lig
Between medial edge of popliteal notch of tibia & cranial part of intercondylar fossa of femur
Function of caudal crucitate lig
Prevents caudal movement of tibia
Meniscal ligaments
Cranial, caudal, inter (transverse) - lateral and medial
Which meniscal ligaments are attached to the femur
Lateral is attached by the meniscofemoral ligament
Medial is unattached
Passive sat apparatus
Patellar locking mechanism
Reciprocal mechanism
Suspensory apparatus of fetlock joint
Features of patellar locking mechanism
Patellar loop
Quadriceps femoris contraction
Sartorius and Gracilis contraction
Make up of the patellar loop
Intermediate patellar lig
Patella
Patellar fibrocartilage
Medial patellar ligament
Patella unlocking mechanism
Biceps femoris and tensor fascia latae muscles contract
Patella rotates laterally & into normal position via lat pat lig
What structures are cut if animal cannot unlock patellar lig
Medial patellar ligament - desmotomy
Cut near insertion on tibial, cut loop at distal end of medial pat lig
Tibiofibular joints include
Proximal tibiofibular joint
Distal tibiofibular joint
Joints of the tarsus
Tarsocrural jt
Proximal intertarsal jt
Distal intertarsal jt
Tarsometatarsal jt (intertarsal)
Feature of tarsocrural joint
Most movable
Tarsal joint capsule
Talocrural sac
Proximal intertarsal sac
Distal intertarsal sac
Tarsometatarsal sac
Significance of tarsocrural jt in species
EQ & carn - calcaneus not involved
Rum & pig - between tibia, talus, calcaneus
Significance of proximal intertarsal jt in rum
More mobile in rum and pigs bc of the talus distal trochlea
Hock joint includes
Tarsocrural jt
Proximal intertarsal jt
Distal intertarsal jt
Tarsometatarsal jt
Intertarsal
Important 3 ligs in hock joint
Collateral ligament
Medial and lateral
Long plantar ligament
Curb condition in EQ
Condition of long plantar ligament
Curve in calcaneus region
Always, never, sometimes
In tarsus, proximal two joints ALWAYS communicate
The distal intertarsal and Tarsometatarsal sometimes
Large dose medial pouch
Easily punctured/injuries
spavin
Condition of horses tarsus
Thouroughpin
Distentsion of synovial sheath of DDFT
Reciprocal apparatus is made up from
Peroneus tertius muscle - passively pulls towards the stifle
SDF M
