Osteoporosis is “… a [silent] skeletal disorder characterized by compromised bone strength predisposing to increased risk of fracture.” (1)(p.7) Estimates suggest 200 million women worldwide and 10 million Americans have osteoporosis. (1-4) Bone strength reflects the integration of two main features: bone mineral density (BMD) and bone quality. Body regions with high trabecular bone content are the most affected by osteoporosis, with fractures of the spine, proximal femur (hip), distal forearm, proximal humerus, and pelvis being the most common. (2, 4) Men comprise 20% to 25% of patients with hip-fracture as a result of osteoporosis. (4)
