Fig. 2From: Quantitative analysis of paraspinal muscle atrophy after oblique lateral interbody fusion alone vs. combined with percutaneous pedicle screw fixation in patients with spondylolisthesisa The disagreement regarding the bilateral intervertebral space. One side of the intervertebral height space at L3/4 is significantly smaller than on the other side (yellow arrow). b The red arrow indicates that the trailing edge of the L3 vertebral body above the L3/4 disc protrudes backward from the posterior edge of the L4 vertebral body, suggesting that adjacent segment degeneration has occurred. The white arrow indicates postoperative edema of the fascia behind the lumbar spine in the regular OLIF groupBack to article page
