Chronic osteomyelitis is a form of osteomyelitis that develops insidiously over months or years. It's usually related to bone ischemia or necrosis, due to how ischaemic or necrotic bone is not reached by antibiotics and the immune system, proving grounds for a chronic infection. Chronic osteomyelitis results in bone destruction and sequestrum formation. It's difficult to treat and it often recurs. | |||

== Brodie abscess == | |||
Brodie abscess is a cystic region of pus and necrosis encapsulated by a rim of sclerotic bone. It occurs in the setting of chronic osteomyelitis in the metaphysis of long bones. It typically affects the distal tibia and is relatively more common in younger patients. It's managed with surgical opening, antibiotics, and autologous bone implantation. | |||
== Sclerosing osteomyelitis of Garré == | |||
Sclerosing osteomyelitis of Garré is a form of chronic (bacterial) osteomyelitis which lacks signs of active infection. It causes sclerosis and bony proliferation. It typically affects children and young adults, usually localised to the mandible secondary to a dental infection, but it can also affect the metaphysis or diaphysis of long bones. It's managed by surgery and antibiotics.<section end="orthopaedics" /> | |||
