Osteomyelitis
Urgent
Osteomyelitis is an infection and inflammation of bone. It may develop when bacteria or other microorganisms reach bone through the bloodstream, spread from a nearby infection, or enter through an open wound or surgery. Symptoms can include localized bone pain, swelling, warmth, redness, fever, and reduced use of the affected area. Prompt diagnosis and treatment are important to prevent complications.

When to Seek Medical Attention
Osteomyelitis is a bone infection that requires prompt medical assessment and treatment. Seek care for persistent bone pain, swelling, redness, drainage, fever, or a wound that is not healing, particularly when infection may have spread from nearby tissue. Emergency evaluation is needed for rapidly worsening infection, severe weakness, confusion, fainting, or other signs of serious systemic infection.

Overview
Osteomyelitis is an infection and inflammation of bone. It may develop when bacteria or other microorganisms reach bone through the bloodstream, spread from a nearby infection, or enter through an open wound or surgery. Symptoms can include localized bone pain, swelling, warmth, redness, fever, and reduced use of the affected area. Prompt diagnosis and treatment are important to prevent complications.

Causes 2
Osteomyelitis is usually caused by bacteria, although other microorganisms can occasionally be responsible. Infection may reach bone through the bloodstream, spread from nearby infected tissue, or enter directly after an open fracture, penetrating injury, surgery, or placement of medical hardware. Staphylococcus aureus is a common cause. The organisms involved and route of infection can vary according to the person and clinical setting.
Infection
Kidney Disease
Risk Factors
Risk factors include diabetes, poor circulation, weakened immunity, chronic kidney disease, recent surgery, open fractures, penetrating injuries, pressure sores, and infections near bone. People with implanted orthopedic hardware may also have increased risk when infection develops around the device. Recurrent bloodstream infections and conditions that impair wound healing can further increase susceptibility to bone infection.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of osteomyelitis is based on symptoms, examination, blood tests, and imaging. Blood tests may show evidence of inflammation or infection. X-rays can identify bone changes, although early infection may not be visible. MRI is particularly useful for evaluating bone and surrounding soft tissues. In selected cases, a sample of bone or infected tissue may be obtained for microbiological testing to identify the causative organism and guide treatment.
Prevention
Key Prevention Tips
Preventing osteomyelitis involves reducing infection and protecting wounds
Prompt cleaning and appropriate medical care of deep wounds, punctures, open fractures, and surgical sites can reduce the chance of infection reaching bone
Good control of diabetes and other chronic conditions can support healing
People with recurrent infections, poor circulation, or weakened immunity may require particular attention to wound care and early treatment of infections
Prevention Guidance
Preventing osteomyelitis involves reducing infection and protecting wounds. Prompt cleaning and appropriate medical care of deep wounds, punctures, open fractures, and surgical sites can reduce the chance of infection reaching bone. Good control of diabetes and other chronic conditions can support healing. People with recurrent infections, poor circulation, or weakened immunity may require particular attention to wound care and early treatment of infections.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
