Osteoporosis has been recognized throughout antiquity. In the left hand, bottom corner of this slide you see a radiograph of a section of spine removed from a Saxon barrow in the 8th century, and you see quite clearly that there's a vertical compression fracture. Such fractures were reported by Hippocrates more than 400 years before Christ and have been reported throughout antiquity. In the 1820s and 1850s the term osteoporosis was coined to indicate the pathological appearance of bone when it had lost bone volume and bone structure. Sir Astley Cooper documented the most frequent fracture associated with osteoporosis in those days, hip fracture. He showed that it was more common in women than men and he showed that it increased in frequency with age. But our real understanding of osteoporosis stems from research undertaken over the last 75 years, and principally since 1990, when we have developed a uniform definition of osteoporosis based on bone density measurement, developed a number of antiresorptive and formation stimulating therapies against osteoporosis, and developed coherent risk assessment strategies.
