vetmed laminitis
Show Answers:

  1. The ______________ are critical to hold the body eight of the horse.
    interdigitations of the lamellae
  2. If pressure, bleeding, or edema occur internally to the hoof capsule, severe ___________________ occurs.
    disruption of the vascular supply
  3. Soft friable material that falls out of the white line is called ____________, and this is a sign of ___________.
    seedy toe; chronicity
  4. 2 drugs commonly used as analgesics with laminitis.
    phenylbutazone, flunixen
  5. Basic principals for acute laminitis: (2)
    preserve thickness of sole, spread the weight-bearing load to the whole foot
  6. Basic principals of chronic laminitis: (4)
    decrease the shock of impact, move center of pressure to the most comfortable location, enhance ease of movement, protect foot with boots or pads
  7. Soft tissue layer over the bone; richly vascular papillae.
  8. The coronary band is critical because...
    the hoof grows down from it; any permanent defect in the coronary band will produce a permanent defect in the hoof wall, which can be an entry site for bacteria or a cause of pain/tissue separation
  9. Chalky horn-filling space b/w the horn of the hoof wall and the sole; where the interdigitating laminae are.
    white line
  10. The surface of _________ from the laminae slide relative to the cells to the the horn moving distally as new horn is made at the _________.
    keratin; coronary band
  11. There should be ________ depth of sole.
  12. The rotation vector for the hoof.
    DDF tendon
  13. __________ to _________ should be a vertical line if the horse is in balance.
    Hell bulb; cannon bone
  14. For a horse to be in balance, the 3 phalanges should be __________ and ________________.
    in a straight line; parallel to the hoof wall
  15. Signs of inflammation.
    heat, pain, swelling, increased tissue pressure within capsule
  16. ___________ and ___________ cause tissue breakdown.
    metalloproteases; degradative enzymes
  17. How do you radiographically assess the position of P3 in a case of laminitis?
    lateral view
  18. If P3 has sunk downward, what can you palpate in the standing horse?
    depression/dip at the coronary band
  19. A laminitis venogram shows no blood flow in the ____________; therefore, you feel...
    laminae; heat at coronary band and pounding digital pulse (blood shunted at coronary plexus)
  20. __________ dissects up the white line, causing it to be wider on x-ray; this allows...
    Air/gas; dirt and bacteria to get b/w the horn and laminae
  21. It h=takes most horses _________ to grow an entirely new hoof wall.
  22. 5 risk factors for laminitis.
    grain/grass overload, sepsis/endotoxemia, galloping on hard ground (road founder), supporting limb overload, metabolic syndrome (insulin resistance)
  23. What is the characteristic body type of a horse with insulin resistance?
    cresty neck, fat deposits around tail head
  24. What is the characteristic feature of a horse with a pituitary tumor, causing Pars Intermedia dysfunction?
    old horse with long curly hair coat
  25. Clinical signs of acute laminitis. (6)
    heat in foot, walking on eggshells, sawhorse stance (front feet stretched out, hind feet under abdomen), pounding digital pulse, hoof tester sensitivity, abaxial nerve block eliminates lameness
  26. Clinical signs of chronic laminitis. (3)
    variable lameness, dished dorsal hoof, rings on hoof irregular
  27. Describe a dished hoof.
    back of hoof is growing normally and front of hoof is growing more slowly
  28. What do you look for to evaluate a radiograph of a horse with chronic laminitis? (5)
    P3 rotation, short P3, sinking P3, loss of sole, flat sole
  29. How do you treat acute laminitis? (5)
    treat primary problem, pain relief by icing feet, phenylbutazone, support sole, confine animal
  30. How do you treat chronic laminitis? (5)
    limit grass turnout, control body weight, shoes, limit exercise, slowly correct rotation by dubbing toe and lowering heel
