用双能X线骨密度仪测量了健康成人桡骨远端骨密度随年龄的变化，共检测了2789名健康女性(20~95岁)和1255名健康男性(20~87岁)，以及72名女性(52~94岁)和23名男性(51~79岁)的桡骨远端骨折。尽管年龄增长，男性的骨密度仍然相对稳定，而且每十年都明显高于女性。在70岁以上的女性中，骨折组的骨密度显著低于非骨折组。在桡骨远端骨折的男性中，骨密度和年龄之间没有显著差异。在骨折组中，复位后的放射状倾斜度的丧失与骨密度的降低相关，但骨密度与桡长或掌侧倾斜度的减少之间没有显著的回归关系。
Changes in bone mineral density with age were measured in the distal radius of healthy adults using dual energy X-ray absorptiometry, A total of 2789 healthy women (20-95 years old) and 1255 healthy men (20-87 years old), and 72 women (52-94 years old) and 23 men (51-79 years old) with fractures of the distal radius were assessed. Bone mineral density remains relatively stable in men despite aging, and was significantly higher than in women in every decade. In women aged 70 years and more, the bone mineral density a as significantly lower in the fracture group than the non-fracture group. In men with fractures of the distal radius, there were no significant differences between bone mineral density and age. In the fracture groups loss of radial inclination after reduction correlated with decreased bone mineral density, but there was no significant regression between bone mineral density and the decrease in radial length or palmer tilt.
