Does osteoporosis affect the hip more than the shoulder?

Yes. Osteoporosis affects all of the bones in the body. The areas that are affected more are the areas prone to breaking and areas that hold the most weight. The hip and the wrist are prone to breaking, so they are often involved in osteoporosis injuries. The spine holds the most weight, so they can fracture or collapse even without a fall or accident. The shoulder sees less weight and is less injured.
