What anatomical changes in older adults increase the risk of compression fractures?

The anatomical changes in older adults that increase the risk of compression fractures include the shrinkage of intervertebral disc spaces. As individuals age, the intervertebral discs, which act as cushions between the vertebrae, lose hydration and elasticity. This reduction in height and volume diminishes the overall spacing between the vertebrae, leading to increased pressure on the vertebrae themselves.

Consequently, this can result in a higher vulnerability to compression fractures with less force applied, as the supporting structures of the spine are compromised. The decreased disc height means that the alignment and stability of the spine can be affected, contributing to the likelihood of vertebrae compressing under normal weight or during falls.

This understanding of spinal anatomy and the changes that occur with aging is crucial for recognizing potential risks in older populations and allows for better preventive measures to be put in place.
