Horse tarsus Flashcards
What is the most common site for OCD in the talus of a horse?
DIRT
What are the most common sites for simultaneously affected OCD in the talus?
DIRT and lateral talar ridge
What makes a talar OCD lesion clinical?
Large bony fragment - most common of the lateral ridge in heavy horses.
Smaller talar lesions (flattening or semicircular defects) most often associated with where?
Medial talar ridge
Which malleolus is more commonly seen affected by OCD?
Medial
What projection is the best for OCD lesions affecting the malleolus?
DLPMO at 15-30 degrees
Does OCD of the proximal tubercle of the talus have significance?
Usually no.
Avulsion fractures along the tibial malleoli are indicative of what?
Collateral ligament injury
What joints of the talus are most commonly affected by the DJD in the tarsus?
distal intertarsal
Tarsometatarsal
DJD in the talsus is considered one of the most common causes of lameness in a horse T/F
True
Remodeling and smooth bony spurs with no other remodeling of the joint is likely insignificant DJD?
True
Osteophyte formation at the distal intertarsal joint margins are more or less significant than in the tarsometatarsal joint?
More significant

What type of salter harris fracture is most commonly associated with fractures of the tibia in foals?
SH II
What views are the central tarsal bone fractures seen the best? Third tarsal bone fractures?
Central = lateromedial third = DMPLO
What is a warning sign for a fracture of the third or central tarsal bones?
Marked sclerosis with no DJD
What type of fractures are third and central tarsal bones usually?
Slab

Enthesopathy of the tuber calcanei
Where does swelling normally occur with tenosynovitis of the tarsal tendon shealth?
medial aspect of the tarsus
between the tibia and the calcaneus
What passes over the sustentaculum tali?
Lateral digital flexor tendon
What is needed for a complete assessment of the proximal suspensory ligament?
MRI or US
