Adhesion score, fibrosis, fat infiltration, and length of surgery.

Patient	Diagnosis	TLIF	Adhesion score	Fibrosis (mm)	% fat infiltration	Surgery time (min)
1	Spondylolisthesis	L4-L5	4	2.5	10	101
2	Stenosis	L4-L5	2	5	0	135
3	Spondylolisthesis	L3-L5	2	2.5	0	119
4	Stenosis	L3-L5	2	6	5	116
5	Spondylosis	L4-S1	2	2.5	5	77

Adhesion score: 4 = sharp dissection required; 2 = easily detachable.
