Hindlimb lameness Flashcards
what are we looking for with distant exam when investigating lameness
standing square
both sides
conformation
asymmetry
muscle wastage
swelling
What is perineural block
need to work sequentially from distal to proximal
Each block adds additional areas of desensitization to the previous one
what is intra-synovial blocks
much more specific to the structure injected
Can return to block more distal structures
List 4 ways to restrain horse when placing nerve blocks in hindlimb of horse
Capable handler
Nose twitch?
Chemical restraint
Lift ipsilateral forelimb limb
should we clip for joint injections?
Evidence would suggest that we should only clip if it makes palpation of landmarks easier
Clipping unnecessarily may increase skin contamination
where is the most likely sites of forelimb lameness
Vast majority of forelimb lameness is localised to the distal limb- within the hoof
Where is the most likely sites of hindlimb lameness
Vast majority of hindlimb lameness is localised outside of the distal limb (fetlock region, tarsal region, stifle)
If we see Acute lameness, positive to proximal limb flexion (unilateral), effusion of the medial femorotibial joint
Where do we start investigations
Blocking the stifle
If we see:
Chronic bilateral lameness in a sports horse, mild-moderate positive to proximal flexion
Where do we start investigations
Tarsal region – small tarsal joints or proximal suspensory ligaments
If we see:
Acute unilateral lameness in a native pony with marked digital flexor tendon sheath effusion
Where do we start investigations
DFTS
What does a DBLPN ( Deep branch of the lateral plantar nerve block) do
A fairly specific block for the proximal suspensory ligament
