eburnation

A specific type of bone sclerosis consisting of a marbled appearance of weight-bearing joints with complete cartilaginous erosion, leaving polished, sclerotic bone as the new articular surface. Cross-section of the articulation reveals a narrowed joint space, osteosclerosis and cystic changes overlying the affected bone, which is surrounded by bony and cartilaginous overgrowths (osteophytes/exostoses).
