SUMMARY A foal with retained cartilage in the distal metaphysis of the right and left radii and third metacarpal bones had abnormal physeal vasculature. In areas where cartilage was retained, vessels crossed the physis, and branched at the physeal‐metaphyseal junction or at the site of retained cartilage. Vessels appeared to be involved in re‐initiation of endochondral ossification and in the repair reponse to the presence of retained cartilage. In areas where the physis was radiographically and histologically normal, no vessels crossed the physis. A function of transphyseal vessels may be as a reserve blood supply in areas of metaphyseal abnormality, at a stage of maturity when metaphyseal vessels are not well developed.
