Osteoporosis can cause fractures, and inter-rotor fractures are one of the most common and favored sites for osteoporotic fractures. Osteoporotic intertrochanteric fractures can be caused by indirect or direct violence. 90% of patients with rotor fractures have low energy two injuries, and falls with osteoporosis are the main causal mechanism. 1. Exercise In adulthood, many types of exercise contribute to the maintenance of bone mass. Menopausal women who adhere to 3 hours of exercise per week have increased overall calcium. But those who exercise excessively to cause amenorrhea, bone loss is accelerated instead. Exercise can also improve sensitivity and balance. 2. Nutrition Good nutrition is important for the prevention of osteoporosis, including adequate amounts of calcium, vitamin D, vitamin C and protein. From childhood onwards, the daily diet should have adequate calcium intake, which affects the acquisition of peak bone mass. European and American scholars advocate a calcium intake of 800 to 1,000 mg for adults, 1,000 to 1,500 mg per day for postmenopausal women, and 1,500 mg/day for men after age 65 and other patients with risk factors for osteoporosis. The intake of vitamin D is 400 to 800 U/day. 3.Prevention of falls The chance of falls in patients with osteoporosis should be minimized to reduce hip fractures as well as Colles fractures. 4.Medication Effective medication can stop and treat osteoporosis, including estrogen replacement therapy, calcitonin, selective estrogen receptor modulators, and diphosphonates, which can stop bone resorption but have a particularly small effect on bone formation. The drugs used to treat and stop the development of osteoporosis fall into two broad categories, the first being drugs that inhibit bone resorption, including calcium, vitamin D and active vitamin D, calcitonin, diphosphonates, estrogens, and isoflavones; the second being drugs that promote bone formation, including fluoride, anabolic steroids, parathyroid hormone, and isoflavones.
