Question

Reactive tubercular arthritis is known as:

• A. Spina ventosa
• B. Pott's disease
• C. Poncet's disease
• D. None

Hint:

Sterile reactive polyarthritis with TB elsewhere, no bacilli in the joint.

Answer 1

The Correct Option is C

Step 1: The question asks for the term used for a reactive (immune-mediated) arthritis associated with tuberculosis, where the joint itself is not directly infected by the bacilli.

Step 2: Poncet's disease is the correct term. It is a reactive polyarthritis occurring in patients with active tuberculosis elsewhere in the body, with no Mycobacterium tuberculosis found in the affected joints; it settles with anti-tubercular treatment.

Step 3: The distractors describe direct TB infection, not a reactive process. Spina ventosa is tuberculous dactylitis of the short tubular bones of the hands and feet in children. Pott's disease is tuberculosis of the spine (tuberculous spondylitis).

Step 4: Hence reactive tubercular arthritis is Poncet's disease.
