Quantified Global Alignment

Alignment informs outcomes

Global Assessment

EOS assessment provides improved, more reproducible alignment measurements.Leverage full-body EOS images and reports to establish unbiased preoperative objectives and evaluate radiographic outcomes along the continuum of care.


EOS gives us reliable measurements to assess how much lordosis each
patient needs for optimal alignment, which also reduces the stress on
remaining levels in the spine to avoid adjacent segment disease.

Alignment Matters

Alignment is not isolated to complex spinal deformity. Restoring normative spinopelvic parameters has a significant correlation to all spine fusions, including short constructs.3
