Sequestrum
Sequestrum is a piece of dead bone that has become separated during the process of necrosis from the sound bone. It is a common complication of osteomyelitis. The sequestrum acts as a foreign body, and perpetuates a chronic infection.
Causes[edit | edit source]
Sequestra form by the following process:
- An area of bone becomes devitalized following infection or interruption of its blood supply (as in fracture).
- New healthy bone (termed involucrum) forms around the sequestrum.
- The sequestrum separates from the living bone.
- The sequestrum may be reabsorbed, pushed out or remain dormant.
Symptoms[edit | edit source]
The symptoms of sequestrum can vary greatly depending on the location and size of the affected bone. Common symptoms include:
- Pain in the affected area
- Swelling and redness
- Fever
- General discomfort, uneasiness, or ill feeling (malaise)
Diagnosis[edit | edit source]
Diagnosis of sequestrum involves a combination of physical examination and imaging tests. These may include:
Treatment[edit | edit source]
Treatment of sequestrum involves removing the dead bone tissue. This is usually done through a surgical procedure known as debridement. In some cases, antibiotics may also be prescribed to treat any underlying infection.
