Arthritis

Arthritis

Typical changes in inflammatory arthritis:
1) Soft tissue swelling (from synovial inflammation)
2) Periarticular osteoporosis (from the hyperaemia associated with inflammation)
3) Joint space narrowing (from loss of cartilage)
4) Bony erosions (from pannus erosion of bone)
eg rheumatoid arthritis, SLE

Typical changes in non-inflammatory arthritis:
1) Sclerosis/eburnation (from trabecular compression and reactive bone resorption)
2) Osteophytes (from reparative process)
3) Non-uniform joint space narrowing (from cartilage destruction)
4) Cysts (from synovial fluid being forced into bone after cartilage denuded)
eg osteoarthritis
