Tom Smith arthritis is associated with
**Core Concept**
Tom Smith arthritis, also known as tuberculous arthritis, is a form of arthritis caused by the bacterial infection of Mycobacterium tuberculosis. This condition involves the invasion of the synovial membrane and subsequent inflammation, leading to joint destruction and deformity.
**Why the Correct Answer is Right**
Tuberculous arthritis typically affects the weight-bearing joints, such as the hips and knees, and can also involve the spine. The infection occurs when the bacteria are introduced through the bloodstream or directly into the joint, often as a result of a systemic infection or a contiguous focus of infection. The bacteria trigger an immune response, leading to granuloma formation, caseation necrosis, and eventually, joint destruction.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Tom Smith arthritis is a specific type of arthritis caused by Mycobacterium tuberculosis, whereas this option is too broad.
**Option B:** This option is incorrect because it refers to a different type of arthritis altogether, and not a specific type associated with a bacterial infection.
**Option C:** This option is incorrect because it is a different condition altogether, and not related to Tom Smith arthritis.
**Clinical Pearl / High-Yield Fact**
Tom Smith arthritis is a form of granulomatous arthritis, characterized by the presence of granulomas and caseation necrosis in the synovial membrane. This condition is often associated with a systemic infection, and prompt treatment is essential to prevent joint destruction and deformity.
**Correct Answer: D. Tuberculous arthritis**
