Secondary analysis of prospective study. ⋯ Increased erector spinae fatty infiltration is significantly associated with higher ODI scores across all subsections 2 years after lumbar surgery, while higher multifidus fatty infiltration is linked to greater disability in standing and walking. These findings underscore the need to maintain paraspinal muscle health to improve surgical planning, improve rehabilitation outcomes, and reduce postoperative disability.

Retrospective cohort. ⋯ Most patients achieved cost-effectiveness after four years postoperatively, with 56% meeting at five years postoperatively. When revision was avoided, 87% of patients met cumulative cost-effectiveness till life expectancy. Mechanical complications were predictive of failure to achieve cost-effectiveness at two years, while comorbidity burden and medical complications were at five years.

Retrospective study of a multicentric prospective database. ⋯ Subjects with low-grade LSTV present similar alignment as PI-matched No-LSTV subjects, and S1 should be taken as reference to measure spinopelvic parameters. High-grade LSTV subjects have kyphotic L5-S1 segment with more cranial lumbar apex and thoracolumbar inflexion point. In these subjects, spinopelvic parameters should be measured on L5.
