Infecting organism is staphylococcus. The infecting organism form pus under the periosteum of the bone, blocking circulation in and into the bone
Bone forms abscess and the necrosed bone crumbes into small fragments known as sequestrum. New bone my form around the areas making healing impossible
-
symptomps

Causes
-
Contamination from nine surgery, open fracture or traumatic injury
