The relation between osteoporosis of the spine and osteoarthritis of the knee. A study using dual energy X-ray absorptiometry and radiographs.
We investigated the relation between osteoporosis of the spine and osteoarthritis of the knee using dual energy X-ray absorptiometry of the lumbar spine to measure bone mineral density and radiographs of the knee in 82 randomly selected females (mean age 77.5 years). Radiographs of the knee were divided into a normal and severe group. The bone mineral density of the severe group was significantly more than that of the normal group.
