Question 7

Differentials for increased digital pulse

Answer 7

• Laminitis
• Corns
• Subsolar (hoof) abscess
• Keratoma
• Fracture e.g. of navicular, P3, distal P2
• Septic pedal osteitis (secondary to nail in foot)
• Bruising
• Thrush in frog clefts

Question 8

Keratomas are benign/malignant?

Answer 8

Benign

Question 9

True/false: nerve blocks are a good way of localising cases of lameness where there is an increased digital pulse.

Answer 9

False
* If there is lameness + increased digital pulse, we know the problem is in the foot because the digital pulse is increased.
* Sensible next steps might be: static and dynamic clinical exam, radiography, possible MRI/CT.

Question 10

True/false: ultrasound is useful to assess structures inside the hoof.

Answer 10

False
Ultrasound waves cannot pass through the hoof capsule

Question 11

Why do we get increased digtal pulse?

Answer 11

• There is inflammation in the hoof: swelling of tissues and increased blood flow
• The hoof capsule cannot expand so there is increased pressure
• The blood pressure in the digital artery increases and this is palpable as a bounding pulse
