Document Summary
Osteoporosis, or porous bone is a chronic, progressive metabolic bone disease. It is characterized by low bone mass and structural deterioration of bone tissue, leading to increased bone fragility, which predisposes the individual to bone fractures at the hip, wrist, and spine. Osteoporosis is k(cid:374)o(cid:449)(cid:374) as the (cid:862)sile(cid:374)t thief(cid:863) (cid:271)e(cid:272)ause it slo(cid:449)l(cid:455) a(cid:374)d i(cid:374)sidiousl(cid:455), o(cid:448)er (cid:373)a(cid:374)(cid:455) years, robs the skeleton of its banked resources. Bones can eventually become so fragile that they cannot withstand normal mechanical stress. A fracture is the medical term for a broken bone. Fractures are common; the average person has two during a lifetime. They occur when the physical force exerted on the bone is stronger than the bone itself. Your risk of fracture depends, in part, on your age. Complete - the break is across the entire width of the bone. Incomplete - the break is through only part of the bone. Compound - if the soft tissue around the fracture is open.
