Often, the body will try to create new bone around the area of necrosis. The resulting new bone is often called an involucrum. [13] On histologic examination, these areas of necrotic bone are the basis for distinguishing between acute osteomyelitis and chronic osteomyelitis. Osteomyelitis is an infective process that encompasses all of the bone ...
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
Osteomyelitis of the jaws is osteomyelitis (which is infection and inflammation of the bone marrow, sometimes abbreviated to OM) which occurs in the bones of the jaws (i.e. maxilla or the mandible). Historically, osteomyelitis of the jaws was a common complication of odontogenic infection (infections of the teeth). Before the antibiotic era, it ...
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [1] Gradually joint pain may develop, which may limit the person's ability to move. [1] Complications may include collapse of the bone or nearby joint surface. [1]
1. Current or previous treatment with antiresorptive or antiangiogenic agents. 2. Exposed bone or bone that can be probed through an intraoral or extraoral fistula in the maxillofacial region that has persisted for longer than 8 weeks. 3. No history of radiation therapy to the jaws or obvious metastatic disease to the jaws. [7]
Vertebral osteomyelitis often attacks two vertebrae and the corresponding intervertebral disk, causing narrowing of the disc space between the vertebrae. [6] The prognosis for the disease is dependent on where the infection is concentrated in the spine, the time between initial onset and treatment, and what approach is used to treat the disease.
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 ...
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 ...
