Examination: Diagnosis of DSLD-ESPA

Flex test of fetlock joint. DSLD/ESPA horses will fail in two or more legs.
Palpation: Pain response especially in the suspensory branches and fetlock area. Suspensory may be enlarged. May feel very taut while weight bearing and soft /mushy when not weight bearing.
Ultrasound: Follow Dr Mero's Diagnostic Protocol. Also useful is Dr Mero's exam form for SL measurements.
Tissue diagnosis is available from UGA at necropsy. Tissue samples may include tendon ligament bundle of lower leg, one leg affected and one that looks nonaffected. The aortic arch, eye, liver, lungs and skin.

The amount of harvested tissue can include all tissues or just the legs, depending on the amount of diagnostic information requested by the owner.

Injury vs DE

The differences between injury and DE are:

1. Injury usually not bilateral, certainly not quadrilateral
2. If there is fetlock dropping, it occurs at the time of the injury, not as a late development
3. Injuries heal by a combination of tendon regeneration and scar tissue. While ultrasound appearance during an acute DE flare may improve somewhat as that settles down, they do not heal.
4. The enlargement seen in healed injured tendons and ligaments is from scar tissue and does not increase over time. It usually decreases. With DE, enlargement is progressive over time.
5. There is usually no obvious precipitating event with DE, such as racing or pasture accident. With injury there always is.
