What term refers to the periosteal new bone formation seen around infected bone in osteomyelitis?

Periosteal reaction to infection in osteomyelitis leads to the formation of new bone that encases the infected area. This shell of new bone is called the involucrum, and it represents the body's attempt to wall off the infection as the periosteum reacts to the inflammatory process. Inside this involucrum, you may find dead bone known as sequestered bone (sequestrum), which often signifies chronic osteomyelitis. The other terms aren’t about this periosteal response: an osteophyte is a bone spur from degenerative changes, and scoliosis is a lateral curvature of the spine. So, the periosteal new bone formation around infected bone in osteomyelitis is involucrum.
