What is the sequestrum?
sequestrum is a bone disorder that occurs when the fragment of the dead bone separates from the living bone, usually due to injury or disease. The process by which the dead bone is discarded is called necrosis and results in loss of tissue. Bone necrosis takes place after the bone fragment dies and then separates. Although the sequency causes the dead bone separation from the living bone, the dead bone often remains either partially closed or in close contact with the newly formed bone, causing sinus or narrow cavity.
There are usually 206 bones in the human body, all of which serve one or more of the three main functions. Some bones, such as the skull and thoracic basket, work and create a protective barrier around certain structures and organs. Other bones, such as the spine, act to support the weight and posture. Specific bones are also involved in motion. These include bones found in the feet, hips and hands.
bone is not a permanent structure in the body. It is a living and dynamic organ to constantly adaptIt is mechanical, chemical and external influences. It is the largest storage of calcium and phosphate body - minerals that are vital to a number of body processes.
Like all other organs in the body, the bones are susceptible to the disease. Sequestrum is one of many bone disorders and is the death of bone or cell that results in tissue damage. This bone disorder may occur due to infections such as osteomyelitis or injuries such as bone fractures. Sequestrum takes place in localized areas of the body.
necrosis is a secondary process of cell death, resulting in loss of tissue. This process is usually due to traumatic damage, bacterial infections or a condition called ischemia. The term "ischemia" concerns bloodlessness or lack of circulation on a specific part of the body. As a result of the convulsion, blood or artery blocking, also known as thrombosis, may occur.
It is usuallyAbout 12 hours after the death of the bone or cell body, which begins to damage tissue or necrosis. There are no symptoms in these earliest stages. When symptoms begin, they usually occur in the form of pain, reduced movement and possible gangrene development due to reduced blood supply. Tissue damage is permanent and treatment is used to prevent further loss of bones and tissue death rather than to completely cure the condition.
