Abstract: This paper discussed the changes of spine-pelvic imaging parameters before and after surgery with lumbar degenerative disease and their relationship with chronic low back pain after surgery. 160 patients with lumbar degenerative disease were selected as the case group, and 80 healthy cases were selected as the control group. X-rays were used to measure the spine-pelvic imaging parameters of the two groups. The case group were treated with lumbar fusion and internal fixation. The patients were followed up for 6 months, and compared the changes of spine-pelvic imaging parameters before and after the operation, and the relationship between the preoperative spine-pelvic imaging parameters and the patient’s postoperative chronic low back pain was discussed. The measured values of the sagittal vertical axis of the spine (SVA), angle of incidence of the pelvis (PI), and the angle of inclination (PT) of the case group were greater than those of the control group (P<0.05). The lumbar lordosis angle (LL) of the case group was lower than of the control group (P<0.05). The measured values of SVA and PT of the low back pain group were greater than those of the non-back pain group, and the LL value of the low back pain group was lower than that of the non-back pain group 584 (P<0.05). The age, Segments ≥3, degeneration of adjacent segments after surgery, and increased PT value are risk factors for low back pain in patients with lumbar degenerative disease after surgery (P<0.05). There was abnormal changes of lumbar spine curvature in patients with degenerative diseases of the lumbar spine. At the same time, patients with poor postoperative PT value recovery, older age, surgical fusion segment≥3, postoperative adjacent segment degeneration can cause postoperative lumbar pain.
