Abnormal bone metabolism refers to a series of pathologies that lead to problems in bone metabolism, resulting in a series of diseases such as osteoporosis, osteomalacia, and so on. Abnormal bone metabolism is often caused by the following reasons: First, it may be caused by trauma, such as in localized trauma, may cause bone contusion or fracture. During the recovery process, there may be abnormalities in bone metabolism, which may lead to a series of lesions such as osteophytes or non-healing fractures. Second, it may be caused by local inflammation or infection. When such localized lesions occur, it will also affect the bone metabolism, thus producing similar lesions. Third, it may be related to malnutrition. If the patient in a certain period of time to eat not enough, or dietary structure problems, will lead to corresponding abnormalities in bone metabolism, and thus produce osteoporosis and other diseases. Fourth, this situation may also be related to the body’s internal hormone levels. Bone metabolism and the human body with a series of hormones are obviously related, such as with the parathyroid hormone, estrogen, testosterone hormone and so on are related. If the hormones within the body are out of whack, this type of lesion can also occur. Finally, such lesions are also related to bone movement. If the patient’s limbs are inactive for a long period of time, or if they are overactive, this can lead to lesions related to bone metabolism.
