Bone density is an important symbol of bone quality, reflecting the degree of osteoporosis and predicting the risk of fracture. Uneven bone density usually suggests pathologic changes in the bone, such as degenerative osteoarthritis, osteoporosis, trauma, and so on. 1. Degenerative osteoarthritis: osteoarthritis is formed when degenerative lesions occur in the bone and joints, with damage to the articular cartilage as the main cause and involving the whole joint tissues, which can be manifested as joint swelling, pain, and limitation of activities, and can be diagnosed through X-ray examination and MRI examination. 2. Osteoporosis: With the increase of age, the bone strength of elderly patients will decrease, and they are prone to osteoporosis, and the X-ray will show uneven bone density. 3. Trauma: If trauma or fracture has occurred, it may also lead to uneven bone quality and uneven bone density. If you are not feeling well, you should go to the hospital in time to get a clear diagnosis and then the doctor will arrange a scientific treatment plan, and you should not take it lightly or deal with it on your own, so as not to delay your condition.
