The rates of fat embolism in long bone fractures vary from 1% to 30%. The mortality rate of fat-embolism syndrome is approximately 10–20%. [ 7 ] However, fat globules have been detected in 67% of those with orthopaedic trauma and can reach as high as 95% if the blood is sampled near the fracture site.
Osteoporosis can affect nearly 1 in 3 women and the bone loss is the most rapid within the first 2–3 years after menopause. This can be prevented by menopause hormone therapy or MHT, which is meant to prevent bone loss and the degradation of the bone microarchitecture and is noted to reduce the risk of fractures in bones by 20-30%.
Acute compartment syndrome can lead to a loss of the affected limb due to tissue death. [6] [9] Symptoms of acute compartment syndrome (ACS) include severe pain, decreased blood flow, decreased movement, numbness, and a pale limb. [5] It is most often due to physical trauma, like a bone fracture (up to 75% of cases) or a crush injury.
a history of long-term intravenous therapy [1] (for air embolism) Bone fracture (for fat embolism) [4] A septal defect of the heart makes it possible for paradoxical embolization, which happens when a clot in a vein enters the right side of the heart and passes through a hole into the left side. The clot can then move to an artery and cause ...
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
Dysbaric osteonecrosis or DON is a form of avascular necrosis where there is death of a portion of the bone that is thought to be caused by nitrogen (N 2) embolism (blockage of the blood vessels by a bubble of nitrogen coming out of solution) in divers. [1] Although the definitive pathologic process is poorly understood, there are several ...
Fat embolism usually occurs when endogenous (from sources within the organism) fat tissue escapes into the blood circulation. The usual cause of fat embolism is therefore the fracture of tubular bones (such as the femur ), which will lead to the leakage of fat tissue within the bone marrow into ruptured vessels.
Causes include arterial embolisms and skeletal muscle infarction as a rare complication of long standing, poorly controlled diabetes mellitus. [12] A major presentation is painful thigh or leg swelling. [12] Bone: Infarction of bone results in avascular necrosis. Without blood, the bone tissue dies and the bone collapses. [13]
