    The intervertebral disc primarily handles compression forces in the lumbar spine. However, both the disc and posterior elements share significant loads during shear and bending movements.

    Area of Science:

    • Biomechanics
    • Spinal Mechanics
    • Musculoskeletal Research

    Background:

    • The lumbar spine's load-bearing capacity is crucial for spinal stability and function.
    • Understanding how different spinal components share mechanical loads is essential for diagnosing and treating spinal disorders.

    Purpose of the Study:

    • To investigate the load-sharing mechanisms between the intervertebral disc and posterior elements in the lumbar spine.
    • To analyze the biomechanical response of a lumbar motion segment under various loading conditions.

    Main Methods:

    • Development of a two-dimensional biomechanical model of a lumbar motion segment.
    • Inclusion of rigid bodies for vertebrae and elastic springs for intervertebral disc and posterior elements.
    • Simulation of compression, anteroposterior shear, and flexion-extension loads.

    Main Results:

    • The intervertebral disc predominantly resisted compression loads.
    • Both the intervertebral disc and posterior elements substantially contributed to resisting shear and flexion-extension loads.
    • Lumbar motion segment morphology significantly influenced load distribution during anteroposterior shear.

    Conclusions:

    • The intervertebral disc and posterior elements play distinct but complementary roles in lumbar spine biomechanics.
    • Load-sharing patterns are dependent on the type of mechanical stress applied.
    • Spinal morphology is a critical factor in determining how loads are distributed within the lumbar motion segment.
