How might osteoporosis lead to too much kyphosis or hyperkinesis?

Osteoporosis weakens bones, making them more susceptible to fractures and deformities, particularly in the vertebrae. As vertebral compression fractures occur, the spine may curve forward, leading to an exaggerated thoracic curvature known as kyphosis. This postural change can result in a loss of mobility and strength, potentially contributing to hyperkinesis, where individuals may exhibit excessive movement as they compensate for discomfort or instability. Overall, osteoporosis can significantly alter spinal alignment and function, leading to both kyphosis and changes in movement patterns.
