Retardation of endochondral ossification at the distal ulnar growth plate in dogs
Abstract:
Bilateral forelimb deformities associated with retained cartilage cores in the distal ulna were diagnosed in 8 immature giant breed dogs. Five of the dogs were autopsied. Histopathological examination of the distal ulnar growth plate revealed a localised central thickening due to the accumulation of hypertrophic chondrocytes which had failed to undergo the usual development to degeneration. Also the intercellular matrix septa of this cartilage were not calcified. Projections of the abnormal cartilage even persisted into the primary spongiosa. These abnormalities in the process of endochondral ossification of the growth plate produced the lesion of retained cartilage core which was responsible for the development of forelimb deformity.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
