In chronic osteomyelitis, the periosteum can form a new layer around infected bone called

Explanation:
The periosteum can react to chronic infection by laying down new bone to wall off the infected area. This creates a protective outer shell around the diseased bone, known as involucrum formation. Often, a piece of dead bone called a sequestrum sits inside this involucrum, and drainage can occur through channels in the shell. The other terms describe different elements (dead bone, pus beneath the periosteum) and do not represent the new bone layer formed by the periosteum.
