Question

What is sequestrum

Q221 marks★✓

Answer

A sequestrum is a piece of dead (necrotic), devascularized bone that has separated from the surrounding viable bone, typically seen in chronic osteomyelitis — it forms because the segment loses its blood supply (from vascular thrombosis and periosteal stripping caused by pus) and remains as an avascular fragment that the body cannot resorb, often acting as a nidus for persistent infection.
