Reports From National Arthritis Meeting

Dr. Shiel Gives Perspectives Of Interest On Osteoporosis From 2001 Annual Scientific Meeting Of The American College Of Rheumatology

Below are perspectives on key reports presented at the recent national meeting of the American College of Rheumatology:


Osteoporosis is a disorder of the skeleton in which bone strength is abnormally weak. This weakness leads to an increase in the risk of breaking bones (bone fracture).

Normal bone is composed of protein collagen and calcium. Osteoporosis depletes both the calcium and the protein from the bone, resulting in either abnormal bone quality or decreased bone density. Bones that are affected by osteoporosis can fracture with only a minor fall or injury that normally would not cause a bone fracture. The fracture can be either in the form of cracking (as in a hip fracture) or collapsing (as in a compression fracture of the vertebrae of the spine). The spine, hips, and wrists are common areas of osteoporosis-related bone fractures, although fractures can also occur in other skeletal areas, such as the ribs.
