Radiographic parameters include facet angle, cross-sectional area, ligamentum flavum thickness and area, foraminal height and area, translation, Cobb angle, segmental disc angle, disc height, PI, LL, PT, and SS. Cage subsidence and clinical outcomes (VAS and ODI scores) will be assessed after OLIF for each facet joint degeneration grade. Facet joint, OLIF
