Osteomyelitis (OM) is an infection of bone. [1] Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. [1] The feet, spine, and hips are the most commonly involved bones in adults. [2] The cause is usually a bacterial infection, [1] [7] [2] but rarely can be a fungal infection. [8]
A Brodie abscess is a subacute osteomyelitis, appearing as an accumulation of pus in bone, frequently with an insidious onset. [1] Brodie's abscess is characterized by pain and swelling without fever, often resulting from diabetic wounds, fracture-related bone infection, or haematogenous osteomyelitis.
The diaphysis (pl.: diaphyses) is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.
OM may occur by direct inoculation of pathogens into the bone (through surgery or injury), by spread of an adjacent area of infection or by seeding of the infection from a non adjacent site via the blood supply (hematogenous spread). Unlike OM of the long bones, hematogenous OM in the bones of the jaws is rare. OM of the jaws is mainly caused ...
Vertebral osteomyelitis is a type of osteomyelitis (infection and inflammation of the bone and bone marrow) that affects the vertebrae. It is a rare bone infection concentrated in the vertebral column. [2] Cases of vertebral osteomyelitis are so rare that they constitute only 2%-4% of all bone infections. [3]
For example, if an extra bone formed on the ankle, it might grow up to the shin. When used in the phrases "cartilaginous exostosis" or "osteocartilaginous exostosis", the term is considered synonymous with osteochondroma. Some sources consider the two terms to mean the same thing even without qualifiers, but this interpretation is not universal.

A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. [ 1 ] [ 3 ] It is considered to be benign since it does not spread beyond the bone. [ 4 ] Unicameral bone cysts can be classified into two categories: active and latent. [ 4 ]
