30
How would luxation/ dislocation of the elbow joint occur
forced medial impact on the forearm or a lateral impact on the arm in a flexed lebow could dislocate the radius & ulna LATERALLY

antebrachiocarpal & middle carpal joints
39
Ligaments of the carpus important features
different ligaments coverthe whole carpus & restrict movement on the median plan short collateral ligamens span the entire region
40
Flexor retinaculum on the palmar aspect helps to form what
carpal canal
41
Ligaments attach the accessory carpal bone to what
metacarpal IV & V
42
Rows of carpal bones & synovial fluid in joints helps to do what
diffuse concussion | important for when dogs/ cats jump from a height
43
Palmar seasmoids helps stabilize what
metacarpophalangela joint
44
Joints of the pelvic girdle
sacroiliac & pelvic symphsysis
45
Sacroiliac joint made of
combines synovial & cartilaginous (synchondrosis) joint
46
Pelvic symphysis made of
fibrocartilage (synchrondosis)
47
Combination of fibrocartilage & joint capsule of sacroiliac joint do what
provides a firm attachment b/w the bones w/ little movement & offers efficient shock absorption
48
Ligaments of pelvic girdle
``` dorsal & ventral sacroiliac ligaments sacrotuberous ligament (only in dogs) ```
49
Where does sacrotuberous ligament go
runs from caudo-lateral aspect of the sacrum & the first caudal vertebra to the ischiatic tuberosity forms caudo-dorsal border of lesser ischiatic foramen
50
Sacrotuberous ligament is the origin for what muscles
biceps femoris, superficial gluteus, priformis, & tenuissimus muscles
51
Clinical relevance of sacroiliac joint
may become disarticulated due to injury
52
Name for hip joint
Coxofemoral joint
53
Structure of hip joint
true ball-&-socket joint (enarthosis) allowing for a considerable range of movements
54
Acetabulum has an acetabular lip that has what
band of fibrocartilage around its rim
55
Transverse acetabular ligament
extesnion of acetubalr lip that covers the acetabulr notch
56
Ligament of the head of the femur/ round ligament of the hip
attaches b/w fovea capitis of femur to the acetabular fossa
57
Stability of coxofemoral joint
from the depth & extent of acetabulum plus the round ligament of the hip
58
Postion of hip determined by
greater trochanter
59
In a luxated/ dislocated hip joint, what happens
strong pull of deep gluteal muscle takes the greater trochanter craniodrosal to the acetabulum hence, luxated limb appears shorter
60
Do not call it "hip luxation"; instead say
luxation of the head of the femur or dislocation of the hip joint
61
Name for the knee joint
stifle joint
62
Joints that make up the stifle joint
femorotibial joint femoropatellar joint femorofabellar joint tibofibular joint
63
Femorotibial joint
medial & lateral fibrocartilaginous menisci b/w femoral & tibial condyles
64
Ligaments of the femorotibial joint
``` cranial & caudal ligaments meniscofemoral ligaments intermeniscal ligament collateral ligaments cruciate ligaments ```
65
Meniscofemoral ligament cranial or caudal
caudal
66
Intermeniscal ligament cranial or caudal
cranial
67
How do the menisci & tibia move in relation to one another during joint extension
menisci- caudally | tibia- cranially
68
Cranial (lateral) cruciate ligament
runs from caudomedial side of lateral femoral condyle, craniodistally to intercondyloid eminence of tibia
69
Caudal (medial) cruciate ligament
runs from medial condyle of femur, craniodistally to the caudomedial aspect of the popliteal notch on the tibia
70
How might the cranial (lateral) cruciate ligament rupture
upon extreme extension or inward rotation of the stifle joint; "cranial drawer"
71
How might the caudal (medial) cruciate ligament rupture
upon flexion of the stifle joint; "caudal drawer"
72
Cruciate ligaments tighten on inward rotation of the stifle on the femur & assist the collateral ligaments in what
limiting the joints movement
73
Femoropatellar joint
patella slides on teh femoral trochlea
74
"Patellar ligament" is a continuation of what that connects to the tibial tuberosity
Quadriceps femoris
75
Medial & lateral femoropatellar ligaments
connect the fabellae w/ the periosteum of the femoral condyles
76
Medial & lateral parapatellar fibrocartilages extend proximally over
dorsal border patella
77
Femorofabellar joint
formed b/w femoral condyles & fabella
78

86
Where is the stifle joint capsule
extends proximally under the patella, tendons of popliteus, Long Digital Extensor, fabellae, & tibiofibular joint
87
Clinical relavance of luxation of the patella
causes limb to be carried in an extended position
88
How does luxation of the patella occur
pull of Quadriceps glides patella over the femoral trochlea. If the pull of the Quadriceps does not coincide w/ the axis of the femoral trochlea, luxation occurs
