Ultrasonographically what is the normal thickness of the cartilage over the condyles and sagital ridge of MC/T3?
Sagittal ridge 1-1.2mm
Condyles <0.7mm
What is represented by B
Subtendinous bursa
Is there usually fluid in the subtendinous bursa at the dorsal aspect of the fetlock?
no
The palmar recesses of the metacarpophalangeal joint are mostly filled with?
Synovial folds, they do not contain much fluid
Displacement of the dorsal plica away from the articualr surface is a sign of?
Joint distention
What is a non-inflamatory of ‘cold-effusion’
Joint distention in the absence of synovial thickening
Thickening of the synovial fold/ dorsal plica is a sign of what?
Chronic synovitis
What is the normal thickness of the dorsal plica?
Denoix <2mm
Other sources <4mm
What condition results in supracondylar lysis?
Correct Term - Chronic hypertrophic synovitis
Which is more sensitive for early signs of OA radiogrpahs of ultrasound?
Ultrasound - can detect subtle cartilage defects
What is indicated by the yellow arrow?
Thickened dorsal plica
What is demonstrated in this image?
Depression in the dorsal sagittal ridge suggestive of OC
Where is the most common site of OC in the fetlock?
Sagittal ridge
Chip fractures at the dorsoproximal aspect of P1 are more common on which side?
Medial - the medial aspect is more prominent
What is osteochondromatosis?
cartilagenous metaplasia of unknown origin
