1

Laminitis

inflammation of the lamellae of the inner hoof capsule

2

What are the Risk factors for laminitis?

Endotoxemia/Sepsis or SIRS
Endocrinopathies
Trauma: "road founder"
Drug induce
Toxin induce

3

Reperfusion injury

Post vasoconstriction phase and the return of circulation after hypoxic event

4

What diseases can cause Laminitis?

Hyperinsulinemia
Trauma

5

What are the Biomechanical forces of the hoof?

Weight of the horse
Ground countered force
DDFT (tensile) force
Lamina
Extensor Tendon

6

Obel grade 1

shift weight from one foot to the other, but will move relatively freely

7

Obel grade 2

lameness is more obvious, when turning, stilted gait and shuffling

8

Obel grade 3

reluctant to move and resists any attempt to lift a foot because of the pain this will induce in the contralateral foot

9

Obel grade 4

most severe grade, immobile and often recumbent

10

What is the measurement from the navicular bone to the hoof?

12mm

11

If the CE is more than 12mm what is the diagnosis?

Laminitis

12

What is the measurement of the HWL?

18mm

13

What is the diagnosis if the HML is more than 18mm?

Acute Laminitis

14

What is the appropriate Sole depth?

10mm

15

What is the treatment for the Developmental phase of Laminitis?

Treat primary cause
Cryotherapy

16

What is the treatment for Acute Laminitis?

NSAIDs
Pain management
DMSO
Pentoxifylline
Atropine

17

What are the treatment options at the hoof level?

Decreasing the tnesion of the DDFT on the coffin bone
Unloading the laminar interface
Reducing inflammation
Easing break-over
Protecting sensitive tissue

18

What does the Prognosis for Laminitis depend on?

Amount of Lamellar damage
Hoof conformation
Duration
Coronary band damage
Vascular damage

19

Chronic compensated Laminitis

the coffin bone has displaced and stabilized to some degree
Hoof growth is often slow or distorted

20

Chronic uncompensated Laminitis

The coffin bone continues to displace
usually suffering from severe pain
