The hardening and polishing of bones giving them an ivory-like appearance, often as a result of the degeneration of bone cartilage.
Eburnation usually occurs in bone surfaces that have become less protected as a result of degeneration of the articular cartilage. The bones then rub with each other, and have become eburnated. The affected bones may become so hard and thick (bone sclerosis) that movements are restricted.
