ABSTRACT
A osteocondrite dissecante (OCD) é definida pela deficiência no suprimento sanguíneo endocondral, sendo a principal consequência a falha na ossificação. Caracteriza-se pela presença de um fragmento osteocondral intra-articular que pode estar livre ou aderido ao osso subjacente. Esta fragmentação ocorre, após a paralisação do processo de ossificação, havendo desordem no rearranjo de condrócitos e necrose da camada basal do osso. A presença deste fragmento pode, causar irregularidade no ambiente articular, gerando uma osteoartrite secundária. Para diagnosticar a OCD, o método comumente utilizado é o exame radiográfico e o tratamento indicado é a retirada do fragmento.
Osteochondritis dissecans (OCD) is defined by the deficiency in the endochondral blood supply, the main consequence being ossification failure. It is characterized by the presence of an intra-articular osteochondral fragment that may be free or adhered to the underlying bone. This fragmentation occurs after the stoppage of the ossification process and there is disorder in chondrocyte rearrangement and necrosis of the basal layer of the bone. The presence of this fragment can cause irregularity in the joint environment, generating secondary osteoarthritis. To diagnose OCD, the commonly used method is radiographic examination and the indicated treatment is removal of the fragment.

Hypertrophic osteodystrophy (HO) is a disease of unknown cause that occurs in young animals of fast-growing breeds, causing periosteal changes in long bone metaphyses. A male Rottweiler, 8 months old was treated at the Veterinary Hospital of UFERSA with swelling joints and lameness. Radiological study observed productive, irregular periosteal reaction, around the distal metaphyseal radius, ulna and tibia (right and left), with increased volume and diffuse radiopacity of the adjacent soft tissue of the metaphyseal regions, with the suggestive diagnosis of HO.
