Fig. 2

Patients in the PEL-TF group, with L4/5 spinal canal stenosis, underwent unilateral decompression through a unilateral approach. A-F is a preoperative imaging examination, which showed stenosis of the L4/5 spinal canal, located in the right lateral recess and intervertebral disc degeneration; G-L represents postoperative imaging examination, indicating satisfactory decompression range; M,N represents the measurement of preoperative and postoperative LRA under CT, and the postoperative LRA increases compared to before surgery; O,P represents the preoperative and postoperative DSCA changes measured under MRI, with postoperative DSCA increasing compared to preoperative; Q represents the nerve image after intraoperative endoscopic decompression, D represents the dural sac, N represents the nerve root, and TS represents the tail side
