Navicular Syndrome – Equine
Irish Sport Horse Fe, 7 year-old
This patient had a history of being reluctant to jump for several weeks.
On dynamic examination it was noted at the walk that the left fore landed lateral to expected foot placement. The right fore landed as expected.
When examined at the trot in a straight line there was a mild (2/10) right fore lameness. When lunged on a soft surface there was a mild (2/10) right fore lameness on the left rein and mild-to-moderate (3/5) right fore lameness on the right rein.
When lunged on a firm ground the patient showed mild (2/10) left fore lameness on a left rein and mild-to-moderate (3/10) right fore lameness on a right rein.
Physiological Screen with Digital Thermal Imaging
Digital thermal images were captured with a Digatherm IR camera.
Dramatic thermal asymmetry was noted in the distal fore limbs with the right limb showing hyperthermia throughout. The right fore hyperthermia was more pronounced medially (Fig 1.1 & Fig 1.2).
