How does osteoporosis contribute to back pain in older adults?

Osteoporosis significantly contributes to back pain in older adults by decreasing bone density, which increases the risk of fractures, particularly in the vertebrae. As bones become less dense and more fragile, they are more susceptible to compression fractures—often occurring with minimal or no trauma. When these vertebral fractures happen, the structural integrity of the spine is compromised, leading to pain, instability, and often a reduction in mobility. This pain can be chronic and may also result in a diminished quality of life, as individuals develop changes in posture and activity levels in response to the pain. Therefore, the connection between osteoporosis and back pain is predominantly rooted in the increased fracture risk due to diminished bone density.
