equine orthoapedics of pastern and fetlcok Flashcards
what joints and bvones are associated with pastern/fetlock
PIPJ
mcpj/mtpj
P2, P3 MC3/MT3
what is the main support of the fetlock region
suspensory ligament
what predisposes the pastern to osteoarthritis and what would be the clinical signs
high load low movement joint
Mild to moderate lameness seen with bony thickening over dorsal pastern
radiographic changes are often seen on the dorsal aspect
what are all the tendons and ligaments associated with pastern region
SL
extensor tendon
extensor branch
collateral ligaments
oblique seasmoidean ligament
straight seasmoidean ligament
collateral seasmoidean ligament
what soft tissue injuries occur around the pastern joint
SDFT branch injury
distal seasmoidean ligament injury
what causes p1 or p2 fractures
acute overload injuries
racehorses
what is the treatment for pastern subluxation
pastern arthrodesis
who is mostly affected by seasmoiditis and what are the usual presenting signs
often seen in young performance horses. seen as inflammation around soft tissues of palmar fetlock
may be related with damage to the SL or annular ligaments following overextension
where is osteochondrosis most likley to occur in the fetlock
saggital ridge of MC/MT3
ofgten leads to formation of osseous cyst
what is palmar/plantar osteochondral disease and what is it associated with
degenerative condition of distal condoyles of young racehorses.
associated with repeated corticosteroid used
what is lesion commonly seen in xray of chronic proliferative synovitis. what is seen on US
crescent shaped bone loss on dorsal aspect of distal MC3.
thickening of dorsal synovial pad seen on US
chronic proliferative synovitis signs
lameness, reduced range of motion, heat/pain.
racing thoroughbreds
