7

lameness exam

-supporting limb=weight bearing
-swinging limb=joint problem

8

lameness exam questions

-history
-visualize at rest or from distance
-observe horse move
-examine legs and body

9

history

-of lameness
-recent change in work load
-pain meds
-cahnges when warmed up

10

visualize at distance

-body type and condition
-fonformation
-abnormal stance
-muscle atrophy

11

observe movement

-circle accentuates lameness on one side
-head bob up with lame leg bearing weight, down with support leg; works for front legs

12

nod with left front=

right front or hind lame

13

nod with right front=

left front or hind lame

14

hind legs

pelvis rises as lame foot hits ground
-severe hind lame causes nod

15

other signs

-short stride
-joint flexion angle
-dog tracking/foot out sideways

16

dogtracking

43
12
1 is the lame leg

17

complications in mild lameness

-no head nodding
-asymmetrical gait
-listen for unequal rhythm of hooves hitting or hitting harder

18

bilateral complications

front nodding cancels it out
-may move oddly and have shorter strider

19

physical exam

-hoof tester for pain
-hoof shape, look for wear
-palpate legs for abnormal swelling, pain, heat, thick tendons, odd range of motion
-diff in muscle size
-palpate back, neck, pain?

20

other tests

-flexion tests
-diagnostic anesthesia/nerve blocks
-radiology
-ultrasound
-MRI
-CT scane

21

flexion tests

hold joints for 30s-2min
-let horse trot off
-if lame will be more pronounced
-helps narrow down location but not precise

22

diagnostic anesthesia

-localizes lameness
- lidocaine nerve block starting low and working up, when lame goes away cause is below block
NOTE: associated soft tissue also desensitized, so does not definite prove exact structure causing lameness, give general area
-bilateral lameness will expose other leg

23

radiology

identifies lameness due to bone lesions, fractures, arthritis, bone cysts

24

ultrasound

tendon and ligaments commonly injiured
-considered gold standard for eval of tendons and ligaments

25

nuclear scintigrapy

bone scan via injection of radioisotopes in blood
-sceen to find increased metabolic activity

26

mri and ct scane

view both soft and bone tissue
