'''Involucrum''' is a layer of new [[bone]] growth outside existing bone seen in pyogenic [[osteomyelitis]]. It results from the stripping off of the [[periosteum]] by the accumulation of [[pus]] within the bone, and new bone growing from the periosteum.
It can be seen [[radiography|radiographically]] (e.g. with [[x-ray]]s), but is extremely rare in developed countries as osteomyelitis is rarely left untreated.
