Osteocondrite dissecante em ombro de cão : relato de caso

Abstract

Osteochondritis dissecans (OCD) is an acquired condition of poorly known etiology, characterized by a disorder that makes the endochondral bone avascular, leading to secondary effects on the articular cartilage, such as pain, swelling, possible formation of loose bodies and mechanical symptoms, including joint locking. OCD commonly occurs in young dogs of large and giant breeds, mainly affecting the scapular-humeral joint and other joints, such as elbows, knees and hocks. The main clinical symptom observed is lameness, when this appears it suggests an advanced stage of the disease. The treatment varies from conservative, with the removal of the predisposing factors, to surgeries, like arthrotomy and arthroscopy. The prognosis is variable because it depends on the degree of involvement of the joint.
