Osteomyelitis is a fascinating condition that can affect all parts of the human skeleton. It presents in several distinct ways, but all have varying degrees of inflammation, systemic ill health, bone death, and soft-tissue compromise. Understanding the components of the disease and the interplay between bacteria, biofilm formation, and the host response is critical to successful treatment. Recent advances in diagnostic methods, imaging, local delivery of antimicrobials, and bone reconstruction have greatly improved the outcome for many patients. Surgery remains central to the effective treatment of chronic osteomyelitis and many acute cases. Eradication of infection is largely dependent on the skill of the surgeon in identifying the areas of dead bone and removing them during surgery. Osteomyelitis is challenging and rewarding to treat, and most patients should enjoy prolonged disease-free periods or cure. Holistic care of the patient requires close collaborative working in a multidisciplinary team including physicians, surgeons, nurses, and therapists to achieve the best outcomes.
