Q

what do we look for during a forelimb gait analysis and what does it mean

A
  1. look for a head bob

head drops when weight bearing on normal limb

Q

what does lameness score of 4 mean

Study These Flashcards
A

non-weight bearing lameness

25
what does favoring a leg mean
it uses the leg less than the others
26
T/F: is lameness if bilateral you may not see obvious lameness
true!!
27
what are the things we should look for if lameness is bilateral
1. weight shifting while standing 2. shortened stride 3. bilateral muscle atrophy 4. bilateral compensatory hypertrophy of unaffected limbs
28
what do we look for on visual inspection of confirmation
observe in standing position, know breed differences, and know abnormal body confirmation (which can be breed dependent)
29
what do we look for in posture
hyper flexion or hyper extension of joints, any muscle atrophy, angular limb deformities, body symmetry
30
where are the areas we should look for muscle atrophy
spine of scapula, greater trochanter, quadriceps
31
what do we look for when doing general body palpation
check for muscle atrophy and asymmetry
32
how do we palpate the neck
deep palpation, ventral and lateral flexion, and extend the neck
33
how do we palpate the back
apply pressure to spinous processes down the entire length of the spine
34
how do we check for lumbosacral pain
directly palpate lumbosacral region and apply pressure dorsally to lumbosacral joint (without loading or extending hips)
35
what is important to remember when we are checking for lumbosacral pain
make sure you dont put pressure on hips because you can confuse lumbosacral pain for hip pain!
36
why do we palpate the medial aspect of the knee joint
for swelling! Look for medial buttress, can be an indicator for cranial cruciate ligament rupture
37
T/F: We should localize pain with the patient under sedation
false! We should localize without sedation so we can localize pain
38
T/F: You should do a neurologic exam along with the orthopedic exam
true!
39
what are the rules for localization
always perform at end of evaluation and palpate the lame leg last
40
Explain the steps to localization
1. place patient in lateral recumbency 2. start at most distal part of leg (toes) 3. move each joint through full ROM (range of motion) 4. apply stress to joint medially and laterally to check for excess laxity
41
what is this a picture of
goniometry
42
what are the 4 things we always look for when palpating long bones
1. pain 2. heat 3. swelling 4. instability
43
what do we look for when we palpate each bone, joint, and soft tissue structure
1. asymmetry between limbs 2. abnormal ROM 3. crepitation 4. isolation of joint you are manipulating
44
why is it important to isolate the joint you are wanting to move
because you dont want to move more than one at once or else you can't localize the pain
45
what is the purpose of the ortolani sign test
it is diagnostic for hip dysplasia
46
how do we do the ortolani sign test
1. grasp flexed stifle and apply pressure dorsally while applying counter pressure with the other hand dorsal to pelvis 2. abduct limb slowly
47
what does a positive ortolani sign test look like
movement felt as femoral head reduces back into acetabulum
48
what is the cranial drawer test
gives diagnosis of cranial cruciate rupture
49
what are the landmarks for the cranial drawer test
thumb - lateral fabella index finger - patella other thumb - fibular head other index finger - tibial tuberosity
50
what is a positive sign of the cranial drawer test
greater than about 1-2mm of movement
51
what is the tibial compression test
the tarsus is flexed with force, if the tibia moves forward then there is most likely a cranial cruciate rupture
52
what test is this
tibial compression test
53
what test is this
cranial drawer test
54
what test is this
ortolani sign test
55
what test is this
patella luxation test
56
what are the objectives of doing an ortho exam
1. lameness localization 2. rule out other conditions (like neurological) 3. orthopedic exam will help determine other diagnostics that may be needed
57
what is the purpose of diagnostic imaging for ortho conditions
to diagnose and localize lameness and to rule in/out other conditions
58
when should we use chemical restraint for diagnostic imaging
correct patient positioning, fractious patients, or arthrocetesis/biopsy
59
what are the components for the therapeutic plan
1. discussion with owner regarding orthopedic examination and all diagnostic results 2. include surgical and medical treatment as pertains to case 3. discuss possible complications and prognosis with owners
