Equine tendon and ligament disease REDO Flashcards
What are the most commonly affected tendons?
palmar/plantar metacarpal/metatarsal region
pastern
Where are the weight bearing tendons?
palmar aspect
What are the types of tendon injuries?
Percutaneous: involving trauma, laceration/penetration
Subcutaneous: over-strain (sudden over extension, preceding tendon degeneration with superimposed sudden over extension)
What should we observe in the stance and gait of a horse regarding ligaments and tendons?
Metacarpophalangeal joint extension
palmar metacarpal/metatarsal region tendon and ligaments decreased with reduced weight-bearing (pain) or with fibrosed (stiff) tendon
increased with severe sdft/sl injuries
elevating toe: ddft rupture
What are the signs of superficial digital flexor tendinopathy?
palmar metacarpal swelling
initial lameness variable
pain on palpation
“core” lesion on ultrasound
What are the signs of suspensory ligament desmitis or prximal suspensory desmitis?
lameness variable in degree
acute or insidious onset
conformation (hindlimb): straight hock, overextending MTP joint
What are the clinical signs regarding lameness due to proximal suspensory disease?
often lamer with the limb on the outside of a circle
proximal MC/MT swelling
pain on palpation
What are the signs of suspensory body and branch desmitis?
variable lameness
swelling close to 3rd metacarpal/metatarsal bone - medially and/or laterally
on ultrasound: periligamentar fibrosis very common, bilateral involvement very common
What are the signs of desmitis of the accessory ligament of the deep digital flexor tendon?
swelling in the proximal metacarpal region
dorsal to SDFT
lameness variable, can be absent
generalised enlargment on ultrasound
Where does deep digital flexor tendinopathy usually occur?
almost always within a tendon sheath or birsa
digital flexor tendon sheath
navicular bursa
2 types” mid-substance disruption and marginal tears
