Usage
What is a sequestrum? A sequestrum is a fragment of dead bone or other tissue that has separated from healthy tissue as a result of injury or disease. The proper plural of sequestrum is sequestra. Sequestra often end up in a wound or abscess (a collection of pus). The surgical procedure involving the removal of a sequestrum is called a sequestrectomy. Sequestra can occur in many different areas of the body, such as the arms, legs, feet, spine, and hips. Example: The sequestrum is a bone fragment that was apparently chipped during a particularly forceful high-five.
