    Study Notes

    Risk Factors for Osteomyelitis

    • Increased risk associated with being sexually active.
    • Individuals with sickle cell disease have a higher susceptibility.
    • Previous prosthetic joint replacements can be a risk factor.
    • Vertebral involvement is commonly linked to osteomyelitis.
    • Animal bites, particularly from cats and dogs, can lead to infection.
    • Injection drug use significantly raises the risk of developing osteomyelitis.

    Associated Infections

    • Staphylococcus aureus is the most common pathogen involved in osteomyelitis.
    • Neisseria gonorrhoeae is rare but can lead to septic arthritis more frequently than osteomyelitis.
    • Salmonella infections can also be associated with osteomyelitis.
    • Other pathogens include Staphylococcus epidermidis, Mycobacteria tuberculosis (notably causing Pott disease), Pasteurella multocida, and Pseudomonas aeruginosa.
    • Fungal infections, such as those from Candida, may be linked to osteomyelitis.

    Diagnostic Indicators

    • Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) provide sensitive yet non-specific markers for infection.
    • Radiographs are generally insensitive in early stages but can assist in chronic cases of osteomyelitis.
    • MRI is the preferred imaging modality for detecting acute infections and assessing anatomical extent.
    • Biopsy or aspiration with culture is essential for identifying the specific organism causing the infection.
