Intro to increased digital pulse cases Flashcards
When you feel digital pulses what artery are you feeling
palmar digital artey
When do we feel digital pulses
injury to foot –> inflammation –> swelling and increased blood flow –> increases pressure in foot –> increases blood pressure within the digital artery
List 9 history questions to ask when investigating bounding digital pulses
work horse is in
how is it managed
recent changes
previous lameness
when did it start
has it improved
exercise done recently
when was it last shod/ trimmed
has the owner given treatment
where do we feel the palmar digital pulses
On abaxial margin of the lateral and medial sesamoid bones
T/F it is normal to feel digital pulses in horse
True- but important to know when this is raised
Describe what a normal digital pulse feels like
faint
takes practice
List the things we should assess in static exam of a horse
recumbent, stance
generalised/localised distal limb swelling
hoof temp
wounds/ crack in hoof
effusions present
abnormal hoof rings
defects in the sole
shoe types and integrity
what are hoof testers used for
Used to apply pressure to specific locations around the hoof
Looking for a generalised or localised pain response
percussion of sole
List the things that are assessed on dynamic exam of horse
lame at walk/trot
worse on turns
grade of lameness
worse on hard
which leg/legs lame
how is foot placed on the ground
worse on lunge
response to flexion
List 3 things you look for when pare foot with hoof knife
discolouration
discharge
deviation of white line
List 8 differential diagnoses of raised digital pulses
laminitis
Subsolar (hoof) abscess
Fracture
Bruising
Corns
Keratoma
Septic pedal osteitis
Thrush in frog clefts
List 4 ways to achieve definitive diagnosis of raised digital pulses
History
clinical exam- static and dynamic
radiography
rarely MRI/CT
