- Figure 1
Schematic images depicting all 8 tether constructs (T8–L2). From left to right: (1) rigid, (2) SPT 1, (3) SPT Helix HT, (4) SPT Helix 1, (5) SPT Trans-Helix 1, (6) SPT 2, (7) SPT Helix 2, and (8) SPT Trans-Helix 2.
- Figure 2
Photograph of interspinous ligament hole necessary for the transhelix tethering construct.
- Figure 3
Average range of motion in flexion-extension, lateral bending, and axial rotation for the adjacent level (T9–T10) for single-level constructs. All data were normalized to intact (100%). *P ≤ .05 versus intact.
- Figure 4
Average range of motion in flexion-extension, lateral bending, and axial rotation for the first instrumented level (T10–T11) for single-level constructs. All data are normalized to intact (100%). *P ≤ .05 versus intact; †P ≤ .05 versus rigid; ‡P ≤ .05 versus SPT 1.
- Figure 5
Average range of motion in flexion-extension, lateral bending, and axial rotation for the adjacent level (T9–T10) for 2-level constructs. All data are normalized to intact (100%). *P ≤ .05 versus intact.
- Figure 6
Average range of motion in flexion-extension, lateral bending, and axial rotation for the first instrumented level (T10–T11) for 2-level constructs. All data are normalized to intact (100%). *P ≤ .05 versus intact; †P ≤ .05 versus rigid; ‡P ≤ .05 versus SPT 2.
