Ans: C. Chronic osteomyelitis
- Radiological feature & age is suggestive of chronic osteomyelitis.
Chronic osteomyelitis:
- Weeks or months after the onset of acute infection a sequestrum appears in the follow-up x-ray and the patient is left with a chronic infection and a draining sinus.
Investigations:
- X-ray: Bone resorption with thickening & sclerosis, pieces of dead bone (sequestra) & form of a distinct bony sheath (involucrum).
- Radioisotope scintigraphy is sensitive but not specific, useful for showing up hidden foci of infection.
