Bone erosion is the loss of bone from disease processes.

Erosive arthritis is joint inflammation (arthritis) with bone destruction, and such conditions include rheumatoid arthritis.

[2] Bone erosion is the loss of bone in a certain area, rather than a change in bone density, which is found in osteoporosis.

Surprisingly, bone erosion is not common in osteoarthritis, although there is a subtype of osteoarthritis (erosive osteoarthritis) that may result in bone erosion.
