Study Notes
Pyogenic Osteomyelitis
- Acute osteomyelitis is inflammation of bone and bone marrow, almost always due to infection.
- It's common in children and adolescents, often involving the metaphysis of long bones. In adults, the epiphysis and subchondral regions are more often affected.
- The disease process involves five stages:
- Inflammation: includes bone ischemia and necrosis within 48 hours.
- Suppuration: characterized by a subperiosteal abscess. Pus can reach the skin surface to form a sinus.
- Blood supply limitation results in bone necrosis, or "Sequestrum," which is separated by the action of osteoclasts.
- Involucrum: this is new bone formation that encases the inflammatory focus.
- Resolution or progression to complications.
Chronic Osteomyelitis
- Definition: Chronic osteomyelitis is a progressive inflammatory process due to incompletely healed or persistent suppurative acute infection.
- Characterized by:
- Sequestrum (dead bone) floating inside abscess cavity
- Involucrum (new bone formation in the wall of abscess)
- Cloaca: a cortical defect/sinus tract draining pus to the surrounding soft tissues.
Complications of Pyogenic Osteomyelitis
- Pathologic fracture
- Secondary amyloidosis
- Endocarditis
- Sepsis
- Squamous cell carcinoma in draining sinus tract
Brodie's Abscess
- Brodie's abscess is a subacute form of osteomyelitis.
- It is typically located in the metaphysis of a long bone.
- It appears as a small intracortical abscess surrounded by reactive bone sclerosis.
