| Objective To investigate the causes of hip fracture in elderly patients by analyzing the data of elderly hip fractures in our hospital, and to provide evidence for prevention of hip fracture. Methods A total of570 elderly patients with hip fractures hospitalized in the Beijing Jishuitan Hospital from September 1st, 2015 to August 31st, 2016were collected. The injury factors were analyzed according to age and gender. Results Among the hip fracture patients, 167 (29.3%) were male and 403 (70.7%) were female, with an average age of 79.5 years old (60-100 years). Low-stress fracture presented in 94.9% of elderly patients with hip fractures, and the proportion of fragility fractures increased with age. The fracture site gradually changed from outdoor to indoor with age. The time period of the fracture was mainly in the daytime (8:00-20:00), whether in outdoor or in living room. The time period of hip fractures in the bedroom and bathroom was mainly in the evening (20:00-6:00). The main causes of falls were different corresponding to the area. Among 570 patients, 95.1% had underlying diseases, and the proportion of multiple underlying diseases increased with age. Multiple regression analysis further indicated that the respiratory diseases, mild to severe malnutrition, and the number of underlying diseases were independent risk factors for the severity of new onset acute disease after hip fractures. Conclusion The causes of hip fracture in the elderly include self-factors, drug factors, and environmental factors. Medical staff should educate the prevention knowledge of falls, actively control the underlying diseases and correct osteoporosis, in order to reduce the risk of the hip fracture. |
