Significant effect of cage location and cage angle on intervertebral FH and SDA. A : DLIF at L4–5, cage location : 13.2 mm, CA : 6°, CH : 12 mm; preoperative FH and SDA were changed from 21.2 mm and 1.4° to 27.5 mm and 3.7° postoperatively. B : OLIF at L4–5, cage location : 5.4 mm, CA : 6°, CH : 12 mm; preoperative FH and SDA were changed from 18.7 mm and 9.8° to 19.2 mm and 13.2° postoperatively. C : DLIF at L4–5, cage location : 10.6 mm, CA : 12°, CH : 14 mm; preoperative FH and SDA were changed from 17.9 mm and 5.7° to 20.24 mm and 10.1° postoperatively. D : OLIF at L4–5, cage location: 4.2 mm, CA : 12°, CH : 14 mm; preoperative FH and SDA were changed from 19.8 mm and -1.7° to 19.9 mm and 14.5° postoperatively. FH : foramen height, SDA : sagittal disc angle, DLIF : direct lateral interbody fusion, CA : cage angle, CH : cage height, OLIF : oblique lateral interbody fusion.
