Osteomalacia, which is originally an imaging term, is an additional bone-like image that grows on the edge of the bone on an x-ray plain. Anatomy verifies that the osteophytes are actually deposits of calcium, not bone. The root cause is actually the accumulation of calcium components in the scar caused by the repair of recurrent episodes of chronic inflammation. This inflammatory deposition of calcium is not manifested only in the bone, but inflammation caused by atheromatous plaque in the aorta can also form calcium deposits, called atheromatous plaque calcification; calcium deposits caused by chondritis are called cartilage ossification or calcification. Calcium supplementation is not necessarily necessary for the elderly, but homework to promote calcium absorption must be done. The digestive function of the elderly is less than when they were younger; the food structure is also different from when they were younger; the key is that the elderly are no longer engaged in outdoor work as often as when they were younger. The amount of calcium eaten decreases, the ability to absorb it decreases, and the ability to utilize it also decreases, resulting in an eventual loss of calcium greater than the intake of supplements and the formation of osteoporosis. Osteomalacia and osteoporosis are not contradictory, they are the result of different problems, so treatment and handling should not be put together. Osteoporosis relies on prevention, while osteopenia relies on early treatment, compared to the former which is a bit easier.
