Osteomyelitis of the ribs is most commonly caused by which scenario?

• A. Thoracotomy Incision or Extension From Another Osteomyelitis
• B. Hematogenous Seeding
• C. Direct Trauma
• D. Pneumonia

Answer: (A)

Rib osteomyelitis most often arises from infection spreading directly from a nearby infected area or from a chest procedure introducing bacteria into the bone. A thoracotomy incision provides a direct route for organisms to reach the rib periosteum and cortex, or infection can extend from another osteomyelitic focus into the rib. While hematogenous spread is a common cause for osteomyelitis in other bones and in different patient populations, it is less frequently the primary mechanism for rib infection. Direct trauma can introduce bacteria but isn’t the usual driver of rib osteomyelitis, and pneumonia itself does not typically infect the rib bone directly. So the scenario of a thoracotomy incision or extension from another osteomyelitis best explains rib osteomyelitis.
