Osteoporosis is a skeletal disorder which is characterized by low bone mass and deterioration which leads to an increased risk of fractures. Over 10 million people have osteoporosis and there are 1.5 million osteoporosis related fractures in the United States every year. Our physicians use a combination of Heel Ultrasound and DXA (Dual Energy X-ray Absorptiometry) machines to diagnose and treat osteoporosis. The risk of osteoporosis increases with age and long term steroid use significantly increases the risk of osteoporosis and bone fractures. If you have been on steroids for more than 3 months, ask your Rheumatologist if a DXA scan is appropriate.
