Plain-English summary
During a prepurchase exam, a 3-year-old Freiberger stallion was found to have an osteochondritis dissecans (OCD) lesion, which is a joint condition where cartilage and bone develop abnormally. The problem was located on the back part of the horse's ankle, called the calcaneus, and was best seen using specific X-ray angles. A special scan called a standing computed tomography confirmed that there was a piece of bone that had broken off in this area. The study suggests that using certain X-ray views can help find these types of lesions better during routine checks. Overall, the findings provide new insights into this uncommon condition in horses.
Abstract
An incidental osteochondritis dissecans (OCD) lesion was found in a left tarsus of a 3-year-old Freiberger stallion presented for a prepurchase examination. The lesion was best visualized on the dorsomedial-plantarolateral oblique and dorsoplantar projections. A standing computed tomographic examination confirmed a fragmentation of the dorsodistolateral aspect of the calcaneus. In suspected OCD lesions at the distal aspect of the talus or calcaneus, a dorsoplantar projection of the tarsus improves lesion localization and could be added to the standard radiographic protocol during OCD screenings. Computed tomography allowed more detailed evaluation of a not previously described calcaneal origin of this uncommon presumed OCD lesion in the equine tarsus.
