Plain-English summary
A 3-month-old Friesian colt was brought in because he was limping badly on both front legs, and the lameness was getting worse. X-rays and a full-body CT scan showed serious bone changes in the joints of his legs, particularly around the navicular bone and the ends of the bones in his toes, while the rest of the joint looked normal. Other joints also had small areas of bone damage. A closer examination of the joint tissue after he passed away did not reveal a clear cause for these problems, but it suggested that the joints were not developing properly. Overall, the findings pointed to a suspected issue with the development of the joints.
Abstract
A 3-month-old Friesian colt presented with severe, progressive distal limb lameness in two limbs. Radiographic and postmortem full-body CT imaging revealed severe articular deforming osteolysis and osteoproliferation at the dorsodistal navicular bone margin and the adjacent distal phalanx proximo-palmar/proximo-plantar margin in two limbs, with the remainder of the distal interphalangeal joint being unaffected. Multiple other joints showed small osteolytic subchondral defects. Postmortem histopathological examination confirmed focal joint disease of both distal interphalangeal joints, without an identifiable cause. Based on clinical presentation, imaging findings, and histopathology, regional joint maldevelopment was suspected.
