Quantifying in vitro load-sharing in spinal fusion surgical constructs using strain sensor-equipped fixation rods and force sensor-equipped intervertebral cages

Key Points

• Load-sharing was effectively quantified using strain sensors embedded in fixation rods, demonstrating dynamic behavior during testing.
• Strain readings indicated significant variations under differing loads, showcasing the adaptability of the constructs.
• Observational analysis involving intervertebral cages provided insights into force distribution across the spine during motion.
• These findings may enable improved design and optimization of spinal fusion systems, enhancing patient outcomes.
