Which term refers to the dead bone tissue resulting from a pathological condition?

The term that refers to the dead bone tissue resulting from a pathological condition is sequestrum. This specialized term is used to describe bone that has become necrotic, often due to infection or lack of blood supply, and is "sequestered" or separated from the healthy bone.

In instances of bone infection, such as osteomyelitis, the affected area can lead to the death of bone tissue. This dead tissue can serve as a reservoir for bacteria, complicating the infection and making treatment more challenging. Understanding the concept of sequestrum is crucial for addressing such conditions effectively.

Osteoclast refers to a type of bone cell involved in the resorption of bone tissue. Osteocyte is a mature bone cell that maintains bone tissue. Callus typically refers to the formation of new bone in response to fracture healing, which is a positive physiological response, not a dead tissue. Thus, the other terms, while relevant to bone health and pathology, do not correctly define dead bone tissue as sequestrum does.
