Sequestrectomy
Pronunciation: seh-KWES-treh-TOH-mee
Surgical removal of a bone sequestrum — a fragment of necrotic bone that has separated from the surrounding viable bone.
Full Definition
Sequestrectomy is the operative procedure by which devitalised bone fragments (sequestra) are excised from a wound, most commonly in the context of osteomyelitis or medication-related osteonecrosis of the jaw. The procedure may be conservative (removing only the sequestrum while preserving adjacent bone) or accompanied by broader debridement depending on the extent of necrosis. In editorial work, the term is sometimes misspelled as 'sequestrectomy' with a doubled 'e' or confused with 'sequesterectomy' (nonstandard). The noun form 'sequestrectomy' should be verified against the verb 'sequestrectomise' (British English) or 'sequestrectomize' (American English) for register consistency within the document.
Usage
Usage note: Check spelling carefully — 'sequestrectomy' is correct; 'sequesterectomy' is nonstandard. Match British/American spelling conventions of the publication.
