Abstract: To observe the imaging and clinical characteristics of degenerative lumbar scoliosis, to explore the correlation and closeness of the two, and to provide theoretical basis for the prevention and treatment of degenerative lumbar scoliosis. METHODS: 1. 62 cases of degenerative lumbar scoliosis (DLS), including 28 males and 34 females, aged between 35 and 73 years, with an average of 56.13±7.95 years, were selected as the DLS group, and the imaging data of 60 patients with non-lumbar and lumbar spine disorders in the same period, age group and sex ratio were selected as the control group.2. Detailed history taking and physical examination were performed for the DLS group, and the low back and leg pain The VAS score and SRS-22 score were used to quantify the pain level and quality of life of the patients, and the imaging parameters (lumbar lordosis Cobb angle, anterior convexity angle, stability, rotation of the parietal vertebral body, maximum lateral displacement of adjacent vertebrae, degree of lumbar slippage, area of the lumbar intervertebral foramen, and spinal canal area) were observed and measured. 3. The MRI spinal canal area of the DLS group and the control group The two-sample mean t-test was used, the left and right lateral foraminal area and pre- and post-surgical information of the control group were used in the paired-sample t-test, and the VAS score and SRS-22 score of low back pain and imaging parameters of the DLS group were analyzed by multiple linear regression. Clinical characteristics: Among 62 patients in the DLS group, 51 (82.3%) patients had a history of underlying disease; the history ranged from 3 months to 25 years; 57 (91.9%) patients had low back pain, including 27 men and 30 women, with no significant difference between men and women (P>0.05); 46 (74.2%) patients had lower extremity pain; 22 (35.5%) patients had intermittent claudication 2. Imaging characteristics: DLS patients had a lateral convex Cobb angle of 11.25° to 30.10°, with a mean of 14.22°±3.16°; the anterior convexity angle ranged from -8.25° to 49.75°, with a mean of 18.27°±13.16°; the convexity was to the left in 34 cases and to the right in 28 cases, and the left convexity was approximately equal to the right convexity (34:28). There was no significant difference in the distribution of lateral convexity (P>0.50); 56 cases (90.3%) showed QII vertebral rotation; 41 cases (66.1%) showed vertebral instability; 39 cases (62.9%) showed lateral displacement >3 mm; 34 cases (54.8%) showed sagittal slippage of the vertebral body, and the slippage of the vertebral body was within 65%. In the measurement of lumbar intervertebral foramen and spinal canal area, the area of concave and convex intervertebral foramen and spinal canal in the DLS group were smaller than those in the control group, and the concave intervertebral foramen decreased significantly, and the area of concave intervertebral foramen in the DLS group was smaller than that of the convex side (P<0.05).2 Low back pain was significantly correlated with the maximum lateral displacement of adjacent vertebrae, lumbar stability, area of intervertebral foramen, and anterior lumbar convexity angle; lower limb pain was significantly correlated with the area of lumbar intervertebral foramen, vertebral body of the parietal vertebrae The quality of life SRS-22 score was significantly correlated with the area of the lumbar foramen, stability of the lumbar spine, area of the spinal canal, anterior lumbar convexity angle, lateral displacement of the vertebrae, and rotation of the parietal spine.3 On the basis of adequate decompression and stabilization of the spine, the improvement rate of low back pain was significantly correlated with the correction rate of the maximum lateral displacement of the lumbar spine and anterior lumbar convexity angle, and the improvement rate of lower extremity pain was significantly correlated with the correction rate of the rotation of the parietal spine. improvement rate was significantly correlated with the correction rate of the rotation of the parietal spine and the lateral displacement of the vertebrae, and the quality of life SRS-22 score was significantly correlated with the correction rate of the anterior lumbar lordosis angle, the rotation of the parietal spine and the lateral displacement of the vertebrae. Conclusions: 1. Degenerative lumbar scoliosis is more prevalent in middle-aged and elderly people, with symptoms dominated by low back pain (91.7%) and radiating pain in the lower extremities (74.2%), and some patients have neurological impairment in the lower extremities (27.4%). 2. Imaging characteristics of degenerative lumbar scoliosis: the lateral Cobb angle is small, the left-sided convexity is roughly equivalent to the right-sided convexity, and it is often accompanied by lateral displacement or rotational subluxation of the parietal vertebrae, slippage in the sagittal position, and The lumbar spine is characterized by a decrease in the anterior lordosis angle or posterior lordosis. The area of the lumbar foramina, the stability of the lumbar spine, the rotation of the parietal spine, the area of the spinal canal, and the anterior lumbar convexity angle are significantly correlated with clinical symptoms.4. Adequate surgical decompression, stabilization of the spine, restoration of the anterior lumbar convexity angle, and improvement of the rotation and maximum lateral displacement of the parietal spine are strong guarantees for good results. Adequate decompression, stabilization of the spine, restoration of the anterior lumbar angle, and improvement of the rotation and maximum lateral displacement of the parietal spine are strong guarantees for good results.
