Weight-Bearing MRI Spine Anatomy
Weight-bearing MRI spine anatomy demonstrates dynamic changes in spinal alignment and appearances of the associated soft tissues during weight-bearing compared to non-weight-bearing condition. The spine is a complex mechanical and anatomic structure. The spine must bear substantial weight while providing considerable flexibility with rotational, bending, and transitional motion. This motion must be large enough to provide the functional requirements but controlled enough to prevent injuring the contained spinal cord and the nerve roots that exit between the spinal elements. The vertebral bodies are separate by the intervertebral discs and the facet joints control the rotational, transitional and angular motion. The ligaments of the spine restrict the motion of the spine to prevent spinal instability.
