Involucrum
Involucrum
Involucrum (pronunciation: /ɪnˈvɒl.jʊ.krəm/) is a term used in medicine to describe a layer of new bone growth around a sequestrum (dead bone) in conditions such as osteomyelitis. The term is derived from the Latin word 'involucrum', meaning 'wrapper' or 'covering'.
Definition
Involucrum is a pathological formation of new bone typically seen in the chronic phase of osteomyelitis. It forms as a response to infection or inflammation, and it envelops the necrotic bone tissue, forming a sort of protective sheath.
Clinical Significance
Involucrum formation is a key diagnostic feature of chronic osteomyelitis. It can be detected on radiographs and other imaging studies. The presence of an involucrum often indicates a long-standing infection and may guide treatment decisions.
