High-detail 3D medical animation of a human spine only, no full human body visible.
The spine is shown floating in a neutral dark environment, slightly misaligned with a forward curvature and uneven vertebral stacking.
Over time, the vertebrae gradually adapt to this misaligned position, slowly reshaping and locking into place.
The spinal segments become thicker, denser, and more rigid, with reduced spacing between vertebrae, visually suggesting calcification and permanent structural adaptation.
Subtle bone hardening and surface roughness appear along the spine, indicating loss of flexibility and irreversible change.
Motion is slow and deliberate, emphasizing progression and permanence rather than sudden movement.
Lighting is clinical and dramatic, highlighting bone density and stiffness.
Ultra-realistic 3D medical visualization style.
