Key Points

This research aims to identify predictors for the need for revision surgery following lateral lumbar interbody fusion with lateral plate fixation.
Conducted a retrospective review of patients who underwent lateral lumbar interbody fusion with lateral plate fixation.
Evaluated the fatty infiltration grade of the lumbar multifidus muscle and the degree of ligamentum flavum hypertrophy.
Analyzed surgical outcomes and rates of revision surgery.
Increased fatty infiltration in paraspinal muscles correlated with higher revision surgery rates.
Greater ligamentum flavum hypertrophy was independently associated with the need for posterior revision surgery.

Implication

Retrospective study identifies ligamentum flavum hypertrophy and fatty infiltration as predictors of revision surgery in lumbar surgeries, suggesting refined preoperative evaluations.

Abstract

LLIF+LP surgery yields favorable outcomes for lumbar degenerative diseases with a low reoperation rate. Preoperative evaluation of ligamentum flavum hypertrophy and the FI grade of the lumbar multifidus muscle may assist in guiding surgical planning, preoperative discussions, and management of patient expectations.
