Quantifying in vitro load-sharing in spinal fusion surgical constructs using strain sensor-equipped fixation rods and force sensor-equipped intervertebral cages
The findings demonstrate that anatomical structures play a critical role in load-sharing during spinal fusion, consistently carrying more than 40% of the load, while cages contribute synergistically by maintaining intervertebral height and supporting fusion. This highlights the importance of preserving anatomical integrity during surgery.
