Anatomical and pathological descriptions of five congenital elbow luxations and subluxations in three dogs were based on palpation, radiographs, gross dissection and in one dog, surgical correction. The primary defect in all five joints was hypoplasia, or aplasia, of the medial collateral ligament. The osseous deformities consisted of outward rotation of the proximal ulna, hypoplasia, or aplasia, of the coronoid process, anconeal process and radial notch and a shallow trochlear notch. The proximal ulna was rotated approximately 40–45°. The olecranon was deviated laterally and dorso‐cranially. The syndrome was compared with the deformities of congenital luxation of the radial head in children. An embryonic pathogenesis for congenital elbow luxations in dogs was hypothesized.
