The pathogen may enter the bone directly (non-hematogenous osteomyelitis), usually after trauma or wounds, or from the blood (haematogenous osteomyelitis).<section end="radiology" /> | <section begin="orthopaedics chronic" /><section begin="radiology" />'''Osteomyelitis''' is an infection involving bone, caused by bacteria in most cases.

Acute osteomyelitis develops within days or weeks. It's most common in children < 5 years, where haematogenous spreading of [[S. aureus]] is the most common cause. It also occurs in adults, where direct spread from a trauma, ulcer, or from haematogenous spreading after IV drug use is the most common cause. | Acute osteomyelitis develops within days or weeks.

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. In adults, chronic osteomyelitis is a common complication of acute osteomyelitis. | Chronic osteomyelitis is a form of osteomyelitis that develops insidiously over months or years.

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" /> | Sclerosing osteomyelitis of Garré is a form of chronic (bacterial) osteomyelitis which lacks signs of active infection.
