    The novel L-shaped side-locking plate (NLSLP) was developed to enhance stability in oblique lateral interbody fusion (OLIF) procedures.

  • 2

    Finite element analysis showed that NLSLP significantly reduced range of motion at the L4-L5 segment compared to traditional fixation methods.

  • 3

    In osteoporotic models, NLSLP maintained biomechanical stability with over 65% reduction in range of motion, addressing cage subsidence risks.

  • 4

    NLSLP provided greater restriction in sagittal plane motion than conventional lateral plates, enhancing overall fixation stability.

  • 5

    The NLSLP offers a viable adjunctive fixation option for OLIF, preserving its minimally invasive advantages while improving stability.
