What is the primary cause of osteomyelitis?
- Autoimmune response attacking the bone marrow.
- Degeneration of bone tissue due to aging.
- Genetic mutation leading to bone deformation and inflammation.
- Infection within the bone, introduced by infectious organisms following trauma or surgery. (correct)

Why might older adults with osteomyelitis not exhibit a fever?
- Osteomyelitis is less severe in older adults.

Study Notes
- Osteomyelitis is a bone infection that starts as inflammation.
- It is caused by infectious organisms (virus, bacteria, or fungi).
- It occurs after trauma or surgical repair of a fracture.
Manifestations
- Constant, pulsating, localized bone pain, worsened by movement
- Erythema and edema at the infection site
- Fever (though older adults may not have elevated temperature)
- Leukocytosis and possible elevated sedimentation rate
- Many manifestations disappear if the infection becomes chronic
Diagnostic Procedures
- Bone scan using radioactive material can diagnose osteomyelitis.
- MRI can also facilitate a diagnosis.
- Cultures detect possible aerobic and anaerobic organisms.
- Blood cultures will be positive for offending microbes if septicemia develops.
Treatment
- Long course (at least 4 to 6 weeks) of IV and oral antibiotic therapy
- Surgical debridement can be indicated and a bone graft can be necessary.
- Hyperbaric oxygen treatments can promote healing in chronic cases.
- Surgically implanted antibiotic beads in bone cement can be packed into the wound as a form of antibiotic therapy.
- Unsuccessful treatment can result in amputation.
Nursing Actions
- Administer antibiotics as prescribed to maintain a constant blood level.
- Administer analgesics as needed.
- Conduct neurovascular assessments if debridement is done.
- If the wound is left open to heal, standard precautions are adequate, and clean technique can be used during dressing changes.
