SA Ortho Exam Flashcards
Lameness diagnosis
History
General physical exam
Neurology exam
Orthopedic exam
Neurology exam
CNS, mentation, ambulating, conscious proprioception, spinal reflexes, palpation
Orthopedic exam
History
Visual inspection of stance/conformation
Gait analysis
Palpation - standing / recumbent (affected leg LAST)
Visual inspection
Observation at distance
General thriftiness/weight
Body symmetry
Muscle atrophy
Abnormal conformation (keep in mind breed standards)
Watch sit/stand
Gait analysis
Determine affected leg(s)
Walk, trot, pace, canter, gallop
Lameness can “disappear” in clinic
Stress: tight circles, stair climbing, etc
Ataxia
Grading scale
0 - none
1 - mild weight bearing lameness
2 - moderate weight bearing lameness
3 - severe weight bearing lameness
4 - non-weight bearing lameness
Thoracic limb lameness
Head bob “down on sound”
Drops when weight being on normal leg; lift on lame leg
Pelvic limb lameness
Hip hike
Stride length shortened on lame leg
Normal limb reaches forward faster than lame
Oscillating motion during locomotion (toward normal side)
Palpation - standing
Examine contralateral aspects simultaneous
Effusion, swelling, atrophy, malaligned bony landmarks
Flexion,extension, lateral mvt of neck
Pressure to spinous processes along spine (for pain)
Dorsal pressure to LS region; ventral pressure to LS region rectally
Hip/lumbar extension
Tail life
Palpation - recumbent exam
Start distal on limb —> palpate all joints
Palpate all joints - ROM, individual joint movement
Palpate entire length of bone
Reflexes
Examination of digits
Palpate each digit, joints and long bones of each
Assess pain, swelling, effusion, crepitus, ROM, instability
Digital causes of lameness
Wound, foreign body, interdigital dermatitis, broken nails
Examination of carpus
Effusion best palpated cranially
Instability - palpated medial/lateral
Radius / ulna examination
Long bone palpation
Elbow examination
Effusion between lateral epicondyle and olecranon
Humus examination
Long bone palpation
Shoulder examination
Effusion difficult to palpate
Biceps tendon - medial to greater tubercle
Don’t forget scapula
Tarsus examination
Effusion best felt between distal tibia and tuber calcanei
Instability - medial/lateral
Stifle examination
Effusion best felt medial to patellar tension
Medial buttress —> thickening of medial joint capsule (chronic disease)
Medial/lateral instability
Evaluation of patellar alignment
Push patella medially + internally rotate limb
Push patella laterally + externally rotate limb
Should not be able to lunate patella
Cranial drawer test
Assess stifle stability
Hold landmarks (patella, fabella, tibial tub erosion, fibulae head) and try to push cranially
+ cranial drawer = CCL incompetence
Cranial tibial thrust
Mimic weight bearing
Hold stifle in flex action, dorsiflex paw
Movement of tibial tuberosity = positive test (corroborate cranial drawer test) = CCL incompetence
Examination of hip
ROM, flexion, extension, adduction, abduction, circular
Hip luxation
Palpate landmarks - wing of ilium, is hail tuberosity, greater trochanter - should form triangle
*if cranial dorsal hip luxation —> landmarks for a line
