Implication

Finite element analysis demonstrates superior stability for cortical screw trajectory fixation over pedicle screw fixation in lumbar spine models, highlighting advantages for degenerative fusion.

Key Points

Cortical screw trajectory fixation yields greater stability than traditional pedicle screw fixation across four loading modes in degenerative lumbar spine fusion models.
Finite element method models of L4-L5 lumbar spine segments evaluated intervertebral disc displacement under flexion, extension, torsion, and axial compression loading.
Equivalent or reduced displacement in facet joints highlights cortical screw trajectory fixation as an effective minimally invasive approach for lumbar posterior fusion.
