Brodie's abscess is characterized by pain and swelling without fever, often resulting from diabetic wounds, fracture-related bone infection, or haematogenous osteomyelitis. The condition is often diagnosed through imaging, which reveals distinctive "target signs" such as central necrosis , surrounding granulation tissue, fibrosis , and an ...
Systemic mycotic infections may also cause osteomyelitis. The two most common are Blastomyces dermatitidis and Coccidioides immitis. [citation needed] In osteomyelitis involving the vertebral bodies, about half the cases are due to S. aureus, and the other half are due to tuberculosis (spread hematogenously from the lungs).
A sequestrum (plural: sequestra) is a piece of dead bone [1] that has become separated during the process of necrosis from normal or sound bone. It is a complication (sequela) of osteomyelitis. The pathological process is as follows: infection in the bone leads to an increase in intramedullary pressure due to inflammatory exudates
Exposed and necrotic bone or a fistula that probes to bone in patients with pain, infection, and one or more of the following: exposed and necrotic bone extending beyond the region of alveolar bone (i.e., inferior border and ramus in the mandible, maxillary sinus and zygoma in the maxilla) resulting in pathologic fracture, extra-oral fistula ...
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]
When a bone is broken and exposed to the outside environment, the probability of infection increases. Both the surrounding soft tissues can become infected, as well as the bone itself, which is called osteomyelitis. Additional complications include the broken bone ends not healing, called non-union, and the broken bone ends healing in an ...
Necrotic bone does not undergo resorption; therefore, it appears relatively more opaque. Attempts at repair of ischaemic-damaged bone will usual occur in 2 phases. First, when dead bone abuts live marrow, capillaries and undifferentiated mesenchymal cells grow into the dead marrow spaces, while macrophages degrade dead cellular and fat debris ...
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [1] This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst.
