Osteomyelitis (Bone Infection)

Osteomyelitis is infection of bone, nearly always bacterial, with the inflammation that follows. Germs reach the bone through the bloodstream (the usual route in children, affecting the ends of long bones, and in adults the spine), directly through an open fracture or surgery, or by spreading from a nearby wound such as a diabetic foot ulcer.

Caught early, acute osteomyelitis is usually cured with antibiotics. If it persists, part of the bone dies and bacteria shelter on it in a protective film that antibiotics cannot penetrate. Chronic osteomyelitis then needs surgery to remove the dead bone, and it can flare again even years later.

Symptome

• Deep, constant bone pain that is worse at night
• Localised warmth, redness and swelling
• Fever and chills, mainly in acute infection
• A child refusing to walk or use a limb
• A wound or sinus over the bone that drains pus and does not heal
• A diabetic foot ulcer deep enough to touch bone
• Persistent back pain with stiffness in spinal infection
• A fracture that fails to heal after surgery

Ursachen und Risikofaktoren

Staphylococcus aureus causes most cases. Risk factors are diabetes with foot ulcers, poor circulation, open fractures, metal implants and joint replacements, sickle cell disease, injecting drug use, dialysis lines, pressure sores and a weakened immune system. Salmonella is characteristic in sickle cell disease. Tuberculosis and brucellosis can infect the spine; brucellosis is found in Türkiye and around the Mediterranean and is linked to unpasteurised dairy products.

Wie es diagnostiziert wird

• Blood tests: CRP, ESR and white cell count are raised in most acute cases and are used to track response. Blood cultures may grow the organism.
• MRI: The most sensitive scan; it shows bone marrow swelling within days and maps abscesses and dead bone.
• X-ray: Normal for the first 10 to 14 days, later showing bone destruction or a walled-off dead fragment.
• Bone biopsy and culture: Identifies the organism and its antibiotic sensitivities. Ideally taken before antibiotics are started if you are stable.
• CT or nuclear medicine scans: Alternatives when metal implants or a pacemaker make MRI unsuitable.
• Probe-to-bone test: In a diabetic foot ulcer, touching bone with a sterile probe makes osteomyelitis likely.

Behandlungsmöglichkeiten

• Targeted antibiotics: Usually 4 to 6 weeks, often starting intravenously and switching to tablets that penetrate bone well once the organism is known.
• Surgical debridement: Removal of all dead and infected bone and tissue, the key step in chronic infection.
• Dead space management: Antibiotic-loaded cement beads or absorbable carriers fill the cavity and deliver high local doses.
• Implant removal or exchange: Infected plates or joint replacements are often revised in one or two stages.
• Stabilisation and soft tissue cover: External fixation, bone transport and plastic surgical flaps rebuild the limb after extensive removal.
• Treating the underlying problem: Blood sugar control, restoring blood flow to the leg, offloading ulcers and stopping smoking.
• Amputation: Occasionally the safest route to a healed, functional limb in severe diabetic foot infection.

Wenn es dringend ist

A child with fever who will not bear weight, anyone with bone pain plus high fever, rigors or confusion, spreading redness around a wound, or back pain with fever and new leg weakness or bladder problems needs emergency assessment locally. Sepsis and spinal cord compression cannot wait.

Reisen nach Türkiye zur Behandlung

Acute bone infection should be treated where you are. People travel for chronic osteomyelitis: a specialist opinion, planned debridement with reconstruction, or staged revision of an infected implant. Be realistic about time, as surgery is followed by weeks of antibiotics with blood monitoring, and staged reconstructions need more than one stay. Agree in advance who will supervise antibiotics at home, and bring previous culture results, operation notes and scans.
