Abstract EN
Objective.
Finite-element method was used to evaluate biomechanics stability of extraforaminal lumbar interbody fusion (ELIF) under different internal fixation.
Methods.
The L3–L5 level finite-element model was established to simulate decompression and internal fixation at L4-L5 segment.
The intact finite model was treated in accordance with the different internal fixation.
The treatment groups were exerted 400 N load and 6 N·m additional force from motion to calculate the angular displacement of L4-L5.
Results.
The ROMs were smaller in all internal fixation groups than those in the intact model.
Furthermore, the ROMs were smaller in ELIF + UPS group than in TLIF + UPS group under all operating conditions, especially left lateral flexion and right rotation.
The ROMs were higher in ELIF + UPS group than in TLIF + BPS group.
The ROMs of ELIF + UPS + TLFS group were much smaller than those in ELIF + UPS group, and as compared with TLIF + BPS group, there was no significant difference in the range of experimental loading.
Discussion.
The biomechanical stability of ELIF with unilateral pedicle screw fixation is superior to that of TLIF with unilateral pedicle screw fixation but lower than that of TLIF with bilateral pedicle screws fixation.
The stability of ELIF with unilateral fixation can be further improved by supplementing a translaminar facet screw.
