Early Adjacent Segment Add-On Surgery and End of Construct Revision Surgery after Multilevel Lumbar Lateral Interbody Fusion
Lateral lumbar interbody fusion (LLIF) has become a common procedure to treat degeneration of lumbar segments with a reliable fusion rate. However, a solid fusion and therefore a stiff construct can create enhanced stresses at the adjacent segments, particularly in multi-level LLIF. The aim of this study was to find the rates for add-on surgery for adjacent segment degeneration after multi-level LLIF ending at L5 and to compare to the rate of revision surgery for pseudoarthrosis at the L5/S1 level in those fused bellow L5.
