The relative importance of osteoporosis and risk of falling in causing hip fracture is not known. Femoral neck bone mass was measured in 708 elderly people, all of whom had fallen and injured a hip. Below 75 years of age there was a steep increase in relative risk of fracture with reduced bone mass, measured by Singh grade. Above that age the increase in risk was small, and neuromuscular responses which protect the skeleton against trauma may be more important than bone mass.
骨质疏松症和跌倒风险在导致髋部骨折方面的相对重要性尚不清楚。对708名老年人进行了股骨颈骨量测量,他们均有过跌倒并髋部受伤的经历。在75岁以下,根据辛格分级法测量,随着骨量减少,骨折的相对风险急剧增加。75岁以上,风险增加较小,保护骨骼免受创伤的神经肌肉反应可能比骨量更重要。
