Bone density scanning, also called dual-energy x-ray absorptiometry (DEXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. The image shows a DEXA hip scan in which osteopenia is noted. Osteopenia refers to bone density that is lower than normal density but not low enough to be classified as osteoporosis.
Fractures caused by osteoporosis generally occur in the spine. These spinal fractures (vertebral compression fractures) affect about 700,000 patients each year. They are about twice as common as other fractures due to osteoporosis, such as broken hips and hand joints.
Bone is living tissue, constantly renewing itself. Although bone is strong and relatively flexible, day to day wear and tear causes tiny structural defects, similar to those that occur in the foundations of buildings over time. Calcium-rich sources can help prevent this wear and tear.
The image shows an illustration of osteoporosis in knee joint. Knee is one of the most commonly affected areas. Women are more likely to have it than men. Medicines and surgical options are available as treatment of the knee pain due to osteoporosis. Your doctor may treat the pain in knee with options such as arthroscopy, osteotomy, and arthroplasty.
Osteoporosis, which means porous bone, is a disease in which the density and quality of your bone get reduced. The bones become more porous and fragile. This increases the risk of fracture in your bone even due to a minor injury or fall. Check out this illustration comparing a bone with osteoporosis and a healthy bone of the leg.
