Research Shows Bones Send Signals Across Organ Systems, With 6 Million U.S. Fractures Treated Yearly

Summary
Research over the past 15 to 20 years shows bones are active tissues that not only remodel continuously but also send signals affecting energy metabolism, mineral balance and other organ systems.
Three main bone cell types drive that activity: osteoclasts remove old bone, osteoblasts build new bone, and osteocytes sense mechanical strain to help the skeleton adapt.
Bone also serves as a mineral reservoir and houses marrow that produces red and white blood cells and platelets, linking the skeleton directly to circulatory and immune functions.
Peak bone mass is usually reached by early adulthood, after which breakdown gradually outpaces formation—especially with aging and menopause—raising osteoporosis and fracture risk.
More than 6 million U.S. fractures are treated each year, and the broader view of bone as a living system is shifting research beyond density alone toward bone quality and whole-body interactions.
