OSTEOPOROSIS; INDEPTH KNOWLEDGE OF THE KNOWN 'SKELETAL DISORDER', why Is it called 'SKELETAL DISORDER' Osteoporosis is a major public health problem In the United States, about 1.5 million fractures are attributable to osteoporosis each year. The sites of these fractures are the vertebrae (650,000), the hip (250,000), the distal forearm (Colles' fracture, 200,000), and other skeletal sites (400,000). One third of women over age 65 at some time will suffer vertebral fractures; the lifetime risk for hip fracture in white women, 15%, approximates that of the combined risks of breast, endometrial, and ovarian cancer. The lifetime risk of hip fracture in men, 5 %, approximates that of the risk of prostate cancerosteoporosis is defined as an absolute decrease in the amount of bone to a level below that required for mechanical support or, as Fuller Albright succinctly put it many years ago, "There is too little bone" Osteoporosis is manifested by back pain, loss of height, spinal deformity (especially kyphosis), and fractures of the vertebrae, hips, wrists, and, less frequently, other bones. The most characteristic symptom of osteoporosis is back pain caused by vertebral compression. Typically, a woman within 20 years after menopause develops acute lumbar or thoracic back pain after some ordinary activity such as raising a window or lifting a sack of groceries. The pain may be mild or severe, and it may be localized or radiate to the flank.
