increased the incidence of PFF, supporting the osteoporosis rather than

No, this doesn't support Rowley's view! This merely indicates that exercise slows the progression of osteoporosis. Osteoporotic hips tend to fracture more easily following a fall, so logically exercise will reduce the incidence of hip fractures because exercise reduces the incidence and severity of osteoporosis. In other words, I agree that the vast majority of hip fractures occur in osteoporotic patients, but I still maintain that the vast majority also require a significant trauma in order to produce the fracture. Basically, I don't believe these fractures occur spontaneously, which is what Rowley was suggesting I think.
