In Vitro Comparison of Dynesys, PEEK, and Titanium Constructs in the Lumbar Spine

Figure 7

Normalized left ID at L4-L5. (ID = interpedicular displacement; DYN = Dynesys; TI = Titanium; FE = flexion-extension; LB = lateral bending; AT = axial torsion; AC = axial compression; = significant decrease compared to the Intact condition; ◊ = significant decrease compared to the Destabilized condition; † = significant increase compared to the Intact condition.)
