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 radiographically (e.g. with x-rays), but is seen rarely, mostly in developed countries, as osteomyelitis is infrequently left untreated.

An eight-year-old boy had a sequestrum involving the entire femoral diaphysis removed before significant involucrum had formed. This procedure resulted in a large structural defect. Ten weeks later, the periosteum had completely repaired the effect, and no infection remained. The benefit in this cas
