MSK 8 Flashcards
which ligament is between 2 sesamoid bones
suspensory ligament
what makes up a tendon
Type 1 collagen
Proteoglycans
Glycoproteins
tendinopathy ocurrs in high incidence for which horses
those performing at high speeds
fatigue, weight, shoeing
3 causes of fibril damage
- overstimulation
-understimulation
-poor differentiation between resident progenitor cells
examples of overstimulation leading to tendinopathy
repetitive strain
hyperthermia
re-perfusion injury
where on leg does SDFT injury occur
mid-cannon (above pastern)
SDFT - lameness can heal, but
tendon remains weak
SDFT injury leads to flexion or extension
extension
why are tendons prone to re-injury
scar tissue- less elastic
(want to promote longitudinal collagen organization via physiotherapy)
tx for tendonopathy
controlled exercise
+/- injections (platelet rich plasma, stem cells, etc.)
why is controlled exercise mainstay of tendonopathy tx? can have back at full race training by how long?
helps longitudinal organization of collagen fibril.
1 year.
how to use stem cells
derive from BM sternum
make up w serum
inject into lesion
most common site for DDFT injury
- foot
- then in sheath (lateral fetlock)
if you see effusion fo the DFTS, think _____
tear on lateral DDFT within sheath
tx for tear on lateral DDFT within sheath
tenoscopic debridement
(suturing would cause adhesions)
DDFT injury within foot tx
NSAIDs
controlled exercise
elevate heels
bursal medication, bursoscopy (reduce adhesions)
cobs/native breeds are prone to injuries where
manica flexoria
Proximal suspensory desmitis in FL vs HL
FL - high athletic horses, more acute, responds well to tx
HL - less speed work, slow onset (present w poor perforomance), poor response to conservative tx - perform neurectomy
accessory ligament of DDFT is also known as
IC (inferior check ligament)
