Inorganic substances in the bones of the elderly are relatively increased, and calcium carbonate is greatly increased, while calcium phosphate is correspondingly reduced, and the composition of organic substances with elasticity is gradually reduced. Therefore, the bones of the elderly become harder, more brittle, easy to break. The elderly have 4 parts of the body most likely to fracture: 1, humerus: that is, the arm near the shoulder, the elderly fall, if the elbow or shoulder on the ground, the part is easy to fracture. 2, radius: the distal end of the elderly fall, often reflexively with the hand to support, easy to cause fractures close to the wrist parts. 3, lumbar spine: the elderly suffering from osteoporosis, their spine is easy to be flattened, short height, and even hunchback. 4, hip bone: the hip bone bears the weight of the whole body, if the elderly suffer from osteoporosis, the bone will become fragile, easy to fracture. Doctor’s tip: To prevent fractures in the elderly, first of all, we must prevent the occurrence of osteoporosis, daily diet should eat more calcium-rich food, and often do some physical exercise within the limits of their ability can also help prevent the occurrence of fractures. At the same time, falls are the cause of many fractures in the elderly, so the elderly should pay special attention to prevent falls. When a fracture occurs in an elderly person, the family should take the patient to the hospital in time for treatment.
