What are the rheumatic disease categories that typically cause radiographic features of a noninflammatory arthritis
• DJD (e.g., primary OA and secondary causes of OA, such as traumatic arthritis, congenital bone diseases, others).
• Metabolic or endocrine diseases (e.g., CPPD, ochronosis, acromegaly) may demonstrate findings best characterized as degenerative though the distribution or specific features (such as extensive chondrocalcinosis in CPPD) may allow for more definitive characterization.
