Morphological finding of a large osteochondral defect of the trochlea tali in a foal – a case report
Septic arthritis is the most common result of the passive transfer failure (PTF) of immunoglobulins in foals. Immunoglobulins G play an important role in foal immunity, and they are the first mechanism of protective humoral immunity. In our report, we documented a morphological finding of the PTF in a 16-day-old colt foal admitted at the Equine Clinic with onset of septic arthritis of the right tarsal joint. Due to a bad prognosis even for pasture soundness despite arthritis therapy and antibody supplementation, we decided for euthanasia. Necropsy of the limb revealed a huge osteochondral defect in the lateral talar ridge, which extended into the adjacent bone tissue.
