Stabilization was achieved with a FiberTape cerclage, which was pulled through the spinous process (interspinous technique) or through\u00a0one spinous process and around both laminae (spinolaminar technique). The specimens were tested (1) in the native state, after (2) unilateral laminotomy, (3) interspinous vertebropexy and (4) spinolaminar vertebropexy. The segments were loaded in flexion\u2013extension (FE), lateral shear (LS), lateral bending (LB), anterior shear (AS) and axial rotation (AR).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Interspinous fixation significantly reduced ROM in FE by 66% (<jats:italic>p<\/jats:italic>\u2009=\u20090.003), in LB by 7% (<jats:italic>p<\/jats:italic>\u2009=\u20090.006) and in AR by 9% (<jats:italic>p<\/jats:italic>\u2009=\u20090.02). Shear movements (LS and AS) were also reduced, although not significantly: in LS reduction by 24% (<jats:italic>p<\/jats:italic>\u2009=\u20090.07), in AS reduction by 3% (<jats:italic>p<\/jats:italic>\u2009=\u20090.21). Spinolaminar fixation significantly reduced ROM in FE by 68% (<jats:italic>p<\/jats:italic>\u2009=\u20090.003), in LS by 28% (<jats:italic>p<\/jats:italic>\u2009=\u20090.01), in LB by 10% (<jats:italic>p<\/jats:italic>\u2009=\u20090.003) and AR by 8% (<jats:italic>p<\/jats:italic>\u2009=\u20090.003). AS was also reduced, although not significantly: reduction by 18% (<jats:italic>p<\/jats:italic>\u2009=\u20090.06). Overall, the techniques were largely comparable.
