An introductory overview for this topic. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
Osteomyelitis (OM) is the infectious inflammation of bone. It may be acute or chronic and can be classified as hematogenous or non-hematogenous. It is commonly caused by bacterial infection, but rarely can be due to fungal infection.
Symptoms are commonly non-specific but may include pain, swelling and redness around the affected area. In adults, the most commonly affected site is the spine and in pediatric populations the most commonly affected site is the long bones. Diagnosis is suspected on the basis of clinical presentation and aided by laboratory and imaging studies and made definitive by biopsy and culture of the presenting area. Treatment of bacterial OM involves antimicrobials and can involve surgery or even amputation. Outcomes are generally good when the condition has been present only a short time.
In humans, the condition was described as early as the 300s BC by Hippocrates. Prior to the availability of antibiotics, the risk of death was significant.
How this connects to Orthopaedics
Musculoskeletal health combines bone and joint anatomy, tissue repair, mechanical loading, blood supply and neural control. In growing patients, skeletal maturity and growth plates affect injury patterns; imaging and function should be interpreted together.

What the underlying subject studies
Orthopaedics examines bones, joints, muscles, tendons and related nerves and vessels. Normal biomechanics helps explain how force, alignment, tissue healing and load distribution influence movement and injury.
How mechanisms and evidence connect
Bone and soft-tissue pathology can alter structural stability, circulation or neurological function. Mechanisms, injury pattern and tissue condition matter alongside any single radiographic appearance.
How to develop a sound explanation
Use a labeled region map to identify articulating bones, muscle groups, nerves and movement. Clinical imaging and examination are required to distinguish disorders and plan management.
