Which condition is inflammation of bone and cartilage due to lack of blood flow?

• A. Osteoarthritis (OA)
• B. Arthritis
• C. Kyphosis
• D. Osteochondritis

Answer: (D)

When bone beneath cartilage loses its blood supply, the tissue can die and the overlying cartilage is compromised. This avascular process leads to inflammation and damage in the joint area, sometimes with a piece of bone and cartilage breaking off. That pattern is what osteochondritis describes. It specifically ties bone and cartilage damage to reduced blood flow, which is why it fits the description of inflammation of bone and cartilage due to lack of blood flow. By contrast, osteoarthritis is mainly wear-and-tear degeneration of cartilage, arthritis is a general term for joint inflammation, and kyphosis is a spinal curvature—none of those reflect the blood-flow–related bone inflammation pattern of osteochondritis.
