About Osteoporosis

Osteoporosis is a condition that features loss of the normal density of bone and fragile bone. Osteoporosis leads to literally abnormally porous bone that is more compressible like a sponge, than dense like a brick. This disorder of the skeleton weakens the bone leading to an increase in the risk of breaking bones (bone fracture). Normal bone is composed of protein, collagen, and calcium. 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 osteoporosis-related fractures can also occur in almost any skeletal bone area.

What are the symptoms of osteoporosis?

The osteoporosis condition can operate silently for decades, because osteoporosis doesn't cause symptoms unless bone fractures. Some osteoporosis fractures may escape detection until years later. Therefore, patients may not be aware of their osteoporosis until they suffer a painful fracture. Then the symptoms are related to the location of the fractures.

Fractures of the spine (vertebra) can cause severe "band-like" pain that radiates around from the back to the side of the body. Over the years, repeated spine fractures can cause chronic lower back pain as well as loss of height or curving of the spine, which gives the individual a hunched-back appearance often called a "dowager hump."

A fracture that occurs during the course of normal activity is called a minimal trauma fracture. For example, some patients with osteoporosis develop stress fractures of the feet while walking or stepping off a curb.

Hip fractures typically occur as a result of a fall. With osteoporosis, hip fractures can occur as a result of trivial accidents. Hip fractures may also be difficult to heal after surgical repair because of poor bone quality.
