The use of arthroscopy on osteochondritis dissecans of the shouder

Abstract

The purpose of this research was to evaluate the use of arthroscopy in dogs with osteochondritis dissecans of the shoulder. We have analysed the possibility to see the structures into the joint, changes of the cartilage, synovial membrane and complications. During the arthroscopic procedure occurred periarticular infiltration, iatrogenic lesions of the cartilage, difficulty to do the arthroscopic portal, instrumental portal, triangulation and premature removal of the arthroscope. All the operated animals had sinovial hiperplasia. The cartilage lesions were chondromalacia, erosion, eburnation, osteophyte, fibrillation, flap and joint mice. The arthroscopy brought us important informations about number and place of the flaps and joint mice as well as general condition of the joint. The removal of the flap or joint mice by arthroscopy requires more hability than that for diagnostic arthroscopy, so the surgeon needs to have more experience.
