Example Sentences

“He had the tibia exposed, and we were concerned he would develop a bone sequestrum. It’s potentially life-threatening. That’s when part of the bone is rejected from the rest of the bone. It’s dying,” Dr. Jorge Sanclemente, an equine surgery resident who helped treat Stormy, tells me.

Sequestration also refers to the government seizing the goods of citizens and can even identify the formation of a sequestrum, a detached piece of bone lying within a body cavity caused by necrosis.

From Time

The dead product is present as a slough or sequestrum, when dead soft or hard tissues are detached, entire or in part, from the living; or as a granular detritus contained in a more or less abundant liquid.

The inflammatory process producing the slough and sequestrum is characterized as a gangrenous inflammation of soft parts or a caries of bone, while the process resulting in the formation of the granular detritus, and which has no necessary connection with putrefactive agencies, is called a softening, from the physical condition of its result.

More About Sequestrum

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.

Where does sequestrum come from?

The first records of the word sequestrum come from the 1800s. It comes from a Latin term meaning “something separated.”

Bits of bone or tissue that have separated from healthy tissue, such as through injury, are often described as necrotic, meaning that that portion of it is dead. Such sequestra can cause problems, including preventing proper healing of the affected area. They can sometimes be treated with medicine, but they often need to be removed through a sequestrectomy.
