Abstract

Four horses presenting for lameness were diagnosed with unilateral osteochondral fragmentation (OCF) of the palmarolateral/plantarolateral aspect of the distal phalanx within the distal interphalangeal joint (DIPJ). Histological evaluation of one case supported a diagnosis of osteochondritis dissecans (OCD), with patient age and history from two cases suggesting a traumatic origin. Lesion appearance on conventional radiography, computed tomography (CT), nuclear scintigraphy and magnetic resonance imaging (MRI) are described. Fragmentation was best identified on dorsal 65° proximal-palmaro/plantarodistal oblique (D65°PrPDiO/D65°PrPlDiO) and dorsal 65° proximal-palmaro/plantarodistal lateral o..
