Articular erosion
Periarticular osteopeniaNarrowing of the joint spaces
Soft tissue swelling
Joint deformity
Joint instability due to ligament rupture
Narrowing of the glenohumoral joint
Marginal erosion
High ridding of the humerus
Lateral erosion of the clavicle
Erosion of Odontoid process
Erosion of facet joints
Pannus proliferation directly compresses the spinal cord.
ligamentous destruction can result in atlantoaxial impaction
