Radiography

Radiographic signs of joint disease include:
• narrowing or disappearance of the joint space due to cartilage degeneration and loss

• increase of bone density directly below the joint; this is known as sclerosis

• decrease of bone density directly below the joint; this is known as lysis

• spurs of new bone at the joint margins
• intra-articular fractures (Figure 8.3)

• osteochondrosis lesions

• bone cysts below the cartilage
