Inflammation of the bone and joint is called what condition?

• A. Ostearthritis
• B. Osteomyelitis
• C. Osteitis
• D. Rheumatoid arthritis

Answer: (A)

Think about what each term means in relation to bone and joints. Osteitis is inflammation of bone itself. Osteomyelitis is inflammation of bone due to infection. Rheumatoid arthritis is an autoimmune inflammatory disease primarily affecting joints. Osteoarthritis describes a degenerative joint disease where cartilage wears down and the underlying bone changes, with an inflammatory response in the joint.

Because the prompt describes inflammation involving both bone and the joint together, osteoarthritis is the best fit among these options. The others point to bone-only inflammation, bone infection, or autoimmune joint inflammation without the same bone remodeling aspect that osteoarthritis encompasses.
