L'arthropathie destructrice de l'épaule

Clinical symptoms of an idiopathic shoulder destructive arthropathy occur in elderly patients with a long history of rotator cuff tear and include mild pain, feeling of shoulder instability and a large joint effusion often blood stained. Radiographic features are characterized by an extended resorption of the humeral head often dislocated, erosion of the glenoid and curvilinear calcifications within a distended capsule surrounding the humeral epiphysis. Key aspects in MRI combine a collapse of the humeral head, bone marrow edema in the remnant part of the head and a large joint effusion.
