Equine Musculoskeletal Part II Flashcards
where does the suspensory body originate?
proximal metacarpal 3 and metatarsal 3
why is the suspensory ligament body difficult to image?
contains muscle fibers
muscle fibers appear hypoechoic
easy to misinterpret as area of injury
amount of muscle varies between horses, but symmetric bilaterally
what is enthesiopathy?
bony irregularities
avulsion fragments
what does suspensory branch injury lead to?
repetitive trauma and chronic injury
what are the clinical signs of degenerative suspensory ligament desmitis?
dropped fetlock
generalized fetlock swelling
responsive to fetlock flexion
where does the suspensory body extend to?
2/3 length of metacarpus/metatarsus
are the branches of the suspensory ligament easier to image than the body?
yes: superficial and no muscle fibers
when iss lameness worse with proximal suspensory desmitis?
on soft footing with bad leg on outside
what does suspensory branch injury lead to?
repetitive trauma and chronic injury
what can be seen on ultrasound of severe chronic proximal suspensory ligament desmitis in the hindlimb?
severe enlargement
mottled echogenicity
fiber disruption
+/- cortical irreegularity of MTIII
which horses are overrepresented for degenerative suspensory ligament desmitis?
peruvian pasos/paso finos
what is ultrasound like of degenerative suspensory ligament desmitis?
enlarged size
mixed/mottle echogenicity
fiber tearing
periligamentous thickening
what indicates a pastern ultrasound should be done?
pastern swelling
digital sheath effusion
blocking
