What does the term 'sequestrum' refer to in orthopedic terminology?

1. New bone growth

2. Dead bone

3. Bone fragment

4. A piece of living bone

The correct answer is: Dead bone

The term 'sequestrum' in orthopedic terminology refers to dead bone tissue that has become isolated from the surrounding living bone. This typically occurs as a result of infection, disease, or inadequate blood supply, leading to necrosis or tissue death. In the context of bone healing and orthopedic treatment, the presence of a sequestrum can complicate recovery, as it can serve as a source of ongoing infection or inflammation. It is usually a sign that a more significant underlying issue exists and often requires medical intervention, such as surgical removal, to promote healing and restore health to the affected area. Understanding what a sequestrum is and its implications is crucial in orthopedic practice, particularly in managing conditions like osteomyelitis or chronic infections, where timely identification and treatment of dead bone are essential for patient recovery.
