Which risk increases as mechanical stress on a long bone dramatically reduces due to prolonged immobility following a fracture?

💡 Explanation

Elevated osteoclast activity and bone resorption becomes likely because reduced mechanical stress diminishes the Piezo1 signaling pathway's stimulation of osteoblasts, leading to decreased bone formation and increased osteoclast-mediated bone remodeling. Therefore, bone density decreases, rather than increasing due to osteoblast activity, or changes in collagen or hydroxyapatite.
