Foot pain (Yr 4) Flashcards
what is the standard series of foot radiographs?
lateromedial
horizontal dorsopalmar
dorsoproximal-palmarodistal oblique P3
dorsoproximal-palmarodistal oblique NB
palmaroproximal-palmarodistal oblique (sklyline)
how is a lateromedial radiograph of the foot taken?
put foot on block so it is weight bearing (at edge of the block so its close to the beam)
centre beam 1-2cm below the coronary band, half way between dorsal hoof wall and heels
what can be assessed on lateromedial radiographs?
phalangeal/solar angle
dorsal hoof wall and sole relationship
P3, P2, P1, navicular bone, DIP joint
P3 extensor process
what is the hoof pastern axis?
line draw along pastern and hoof wall should be continuous on lateromedial radiographs
what can you assess when looking at the navicular bone on lateromedial radiographs?
corticomedullary definition
side bone
what is side bone?
mineralisation of the collateral cartilages of P3
how is a horizontal dorsopalmar radiograph taken?
horse stood on block with foot at the back of the block
horizontal beam 2cm below the coronary band
what can be assessed on a dorsopalmar radiograph?
P3 margins (sidebone)
DIP and PIP joint space and margins
navicular bone margins
what are the two versions of the dorsoproximal-palmarodistal oblique?
upright pedal (horses toe on Hickman block)
high coronary (horse stands on tunnel containing the cassette)
is an upright pedal or high coronary dorsoproximal-palmarodistal oblique better?
upright pedal (high coronary causes slight elongation of the foot)
what can be assessed on the dorsoproximal-palmarodistal oblique view?
P3 body, solar margin and wings
how is a dorsoproximal-palmarodistal oblique NB taken?
similar to the P3 but collimate slightly above the coronary band (collimate tightly)
how is palmaroproximal-palmarodistal oblique (sklyline) taken?
foot on cassette tunnel and leg back with fetlock extended
centre beam between the heel bulbs
