    Cefamandole effectively penetrates bone, reaching levels above minimum inhibitory concentrations for key bacteria. This antibiotic shows no bone binding, suggesting potential for treating bone infections like osteomyelitis.

    Area of Science:

    • Pharmacology
    • Orthopedic Surgery
    • Infectious Diseases

    Background:

    • Antibiotic penetration into bone is crucial for treating osteomyelitis.
    • Understanding cefamandole's bone diffusion is essential for its clinical application.

    Purpose of the Study:

    • To evaluate cefamandole penetration into human bone tissue.
    • To determine if cefamandole binds to bone.
    • To compare cefamandole levels with minimum inhibitory concentrations (MICs) of relevant pathogens.

    Main Methods:

    • Studied cefamandole penetration in 32 normal bone specimens.
    • Measured blood contamination using the haemoglobin method.
    • Assessed diffusion in both cortical and trabecular bone.

    Main Results:

    • No cefamandole binding to bone was detected.
    • Mean corrected cefamandole levels (5.8 µg/g) exceeded MIC values for Staphylococcus aureus, Haemophilus influenzae, and Enterobacteriaceae.
    • Similar diffusion patterns were observed in cortical and trabecular bone.

    Conclusions:

    • Cefamandole demonstrates adequate penetration into bone tissue.
    • The antibiotic's levels exceed MICs for common bone infection pathogens.
    • Further research into cefamandole for preoperative prophylaxis and osteomyelitis treatment is warranted.
