Systems for attenuation of increased spinal flexion loads post-fusion and associated methods

A fusion system, comprising:

• a fusion implant capable of connecting to a plurality of fused vertebrae;
• a transition member including a tension component capable of connecting to a fused vertebra of the plurality of fused vertebrae and an unfused vertebra disposed proximate the fused vertebra, the tension component comprising a flexible elongate member capable of passing through an aperture in the transition member to interface with the proximate unfused vertebra;
• and
• a second transition member with a second tension component capable of coupling a second fused vertebra of the plurality of fused vertebrae and a second unfused vertebra positioned proximate the second fused vertebra, the second tension component comprising a second flexible elongate member capable of passing through a second aperture in the second transition member to interface with the second unfused vertebra,
• wherein the tension component is tensionable to a selected value of tension by pulling a first end of the flexible elongate member through the aperture of the transition member to reduce a length of a portion of the flexible elongate member coupled to the proximate unfused vertebra;
• wherein the second tension component is tensionable to a selected value of tension by pulling a first end of the second flexible elongate member through the second aperture of the transition member to reduce a length of a portion of the second flexible elongate member coupled to the second unfused vertebra;
• wherein the second tension component is tensionable independently from the tension component;
• wherein the tension component modulates a flexion range of motion of the proximate unfused vertebra as a function of the selected value of tension of the tension component;
• wherein the transition member post-operatively attenuates spinal flexion loads on the proximate unfused vertebra;
• and
• wherein the second tension component is positioned superior to the tension component.
