Plain-English summary
A 20-week-old male golden retriever was found to have a fragmented medial coronoid process (FCP) in his elbow, but he showed no signs of limping or discomfort. During a separate study, the dog was euthanized, and further examination revealed a dense bone structure in the elbow joint, which was unusual for his age. The tests showed signs of osteochondrosis, a condition where the cartilage and bone don't develop properly, leading to potential joint issues. While this dog did not exhibit symptoms, it highlights the importance of monitoring young dogs for any signs of joint problems.

Abstract
A 20-week-old male golden retriever, which was not lame and showed no clinical signs of a fragmented medial coronoid process (FCP), was euthanased for another study and perfused intravenously with formaldehyde. Gross dissection revealed no abnormalities within the right elbow joint. The medial coronoid process was excised, embedded in methylmethacrylate, scanned in a microcomputed tomography (microCT) scanner and sectioned for histology. The microCT scans revealed a dense trabecular bone structure, much denser than in other dogs of similar age, which was considered to be responsible for the sclerosis visible at the base of the coronoid process in radiographs. Three-dimensional reconstructions indicated that there was a small step within the subchondral bone, extending from the apex towards the radial notch. Histology revealed a necrotic lesion between locally thickened articular cartilage and the subchondral bone, characteristic of osteochondrosis.
