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).

Another might be that the infected cells were lost during the final stages of otosclerotic eburnation. The latter explanation is supported by the well-known morphologic pattern seen in late-stage otosclerosis, in which only a very small number of osteoblasts, blood vessels, and connective tissue cells can be found.
