Degenerative disorders

A. Cotten; Lille/FR

Learning Objectives

1. To appreciate the musculoskeletal imaging manifestations of degenerative disorders.
2. To understand the underlying pathomechanisms involved in these imaging abnormalities.
3. To appreciate the strengths and weaknesses of imaging modalities in assessing these disorders.


Osteoarthritis is the most common joint disease worldwide. It is a major source of pain, disability, and socioeconomic cost. The epidemiology of the disorder is complex and multifactorial, with genetic, biological and biomechanical components. Conventional x-ray is the standard diagnostic method to confirm the clinical diagnosis, to evaluate the degree of severity of osteoarthritis and to look for predisposing conditions. CT can be performed for the assessment of bone stock, anatomic conditions and bone deformation. MRI can be used to confirm early forms and to clarify possible damage and/or wear and tear, which cannot be seen on x-rays. Finally, intraarticular administration of contrast will be performed in selected cases, when a precise assessment of the cartilage or fibrocartilage is required. This lecture will focus on: the role of imaging in clinical practice, the typical and atypical imaging features of OA, the radiological features which should not be read as OA, the main predisposing factors that have to be known and searched.
