COJERA O DEBILIDAD ORTOPEDICO O NEUROLOGICO: COMO DIFERENCIARLOS?

Attendees will be challenged with video cases and will need to decide if the case is an orthopedic or neurological problem. We will explore cruciate rupture, hip dysplasia, luxating patellae, malignant nerve root tumors, disc disease, discospondylitis, and a few “tricks”. Are you up to the challenge? Osteochondritis Dissecans (OCD) Osteochondritis Dissecans an inflammatory condition that occurs when the diseased cartilage separates from the underlying bone. Normal joint stresses, focal trauma (excessive weight), or some other unknown mechanism causes cracks and fissures to develop in the zone of chondrocytes of the epiphyseal cartilage layer. Ultimate extension of these fissures into the joint results in the release of cartilaginous breakdown products into the joint fluid with a resultant synovitis, inflammation of subchondral bone and cartilage (osteochondritis), and creation of a flap of cartilage that dissects away from its underlying subchondral attachments (dissecans). The cartilaginous flap may initiate superficial erosions of the cartilage of the opposing joint surface contributing further to the inflammatory arthritis. The dissection of synovial fluid into subchondral bone results in a focal necrosis of the bone and bone marrow under the flap. If the flap is extensive and the dog is of sufficient weight a large area of avascular necrosis of the bone and bone marrow results, followed by entrapment of synovial fluid and subsequent cyst formation […]
