Biomechanical evaluation of a novel anatomical plate for oblique lumbar interbody fusion compared with various fixations: a finite element analysis.

ABSTRACT:

Background

To build a model of an anatomical plate for oblique lumbar interbody fusion (OLIF) surgery based on previous anatomical parameters and verify the biomechanical effect with finite element analysis.

Methods

The anatomical plate model was built with AutoCAD and Solidworks. Finite element models of the L2-3 and L4-5 segments were established with computed tomography images from a 46-year-old asymptomatic male individual. Six fixation technique models were created: (I) stand-alone (SA); (II) bilateral pedicle screws (BPS); (III) lateral rod-screw (LRS); (IV) lateral rod-screw plus facet screw (LRSFS); (V) two-screw lateral plate (TSLP); (VI) anatomical plate. The range of motion (ROM), the cage stress, and the instrument stress were calculated under different motion st
