Summary: The study aimed to investigate the influence of dural tube compression on the presence and development of lumbar spinal stenosis (LSS) symptoms, as well as the prediction of surgery during the follow-up period. The results showed that severe dural tube compression did not persist symptoms and could not predict symptom development and surgery.

Summary: This study aimed to investigate the differences in the natural history of lumbar spinal stenosis (LSS) based on the severity of stenosis on MRI and to estimate the probabilities of surgical treatment based on radiological severity. The results showed that the highest percentage of surgical treatment was observed in grade 3 maximal central stenosis, and the surgical probabilities varied depending on the concomitant central stenosis and foraminal stenosis.

Summary: Lumbar spinal stenosis (LSS) is a significant health issue in aging societies, as it can greatly impact quality of life and daily activities. This study aimed to examine the 10-year progression of LSS symptoms in a community population of over 1000 individuals through prospective data collection. The findings revealed that the presence of LSS symptoms at the initial survey was a strong predictor of symptoms after 10 years. However, 60% of individuals who initially presented with LSS symptoms did not continue to show symptoms at the 10-year follow-up, consistent with the 1-year and 6-year findings.

Summary: The study demonstrates the favorable long-term efficacy of SCS in treating neurogenic claudication, especially for patients without prior surgical decompression. Despite its retrospective nature and single-center design, the results suggest that SCS can be considered as part of conservative treatment to help patients alleviate spine-related pain.

Summary: The study found that in patients with DLSS, the atrophy of muscles in stenotic segments of the spinal canal is significantly greater than in non-stenotic segments, and there is a strong positive correlation between the severity of multifidus atrophy and the severity of spinal stenosis.

Summary: The majority of subjects with initial LSS symptoms became LSS-negative after 6 years, while a portion of LSS-negative subjects turned LSS-positive. Lower RDQ score and initial positive LSS symptoms were identified as predictive factors for the presence of LSS symptoms during the six-year follow-up period.

Summary: The purpose of this study was to investigate the findings of electrodiagnostic studies in patients with moderate and severe lumbar central spinal stenosis. The results showed significant alterations in NCS and EMG in patients with LCSS, especially in those with severe LCSS. These findings may aid in diagnosing LCSS-induced radiculopathy and differentiating it from other causes of peripheral nerve pathologies.

Summary: This study aims to identify factors associated with paraspinal muscle morphology in patients with lumbar spinal stenosis (LSS) using objective physical and degenerative spine assessments. The results suggest that disc degeneration, endplate abnormalities, and lumbar spinopelvic alignment are more closely related to paraspinal muscle atrophy or fat infiltration than spinal stenosis and LSS symptoms.

Summary: The study revealed that 61.4% of lumbar spinal stenosis (LSS) patients also have asymptomatic spondylotic cervical spinal stenosis (ASCSS), with lumbar lordosis angle (LLA) >35.85 degrees and dural sac cross-sectional area (DCSA) <84.50 mm^2 being risk factors for ASCSS development. Additionally, the cervical stenosis index showed a significant positive correlation with the lumbar stenosis index.

Summary: The most important aspect of LSS is that it is not a hernia, but rather a calcification resulting from bone deformation. The diagnosis of LSS is challenging due to the expertise required for interpreting biomedical images. Recent literature suggests that the U-Net method has achieved high success in semantic segmentation. In this study, three different deep learning methods were used for semantic segmentation of lumbar spine MR images, with the ResUNet model achieving the highest segmentation success rate of 0.93 DICE score among 1560 images. The treatment of LSS is crucial due to the difficulty in interpreting MR images and differentiating it from lumbar hernia.

Summary: Identifying genetic risk factors for lumbar spine disorders through genome-wide association studies using electronic health record data may lead to the development of new treatments. The study identified two novel associations with lumbar spine disorders, including lumbosacral radicular syndrome and lumbar spinal stenosis. Replication in an independent sample confirmed the association with lumbar spinal stenosis.

Summary: This study used a deep learning model to automatically classify central canal stenosis, neural foraminal stenosis, and facet arthropathy in lumbar spine MRI. The results showed that the deep learning system achieved high accuracy in these classification tasks.

Summary: Lumbar spinal stenosis (LSS) is a common disease in the elderly, and decompression surgery is the standard treatment. Traditional total laminectomy may cause post-surgical instability, leading to the development of various minimally invasive techniques. This article provides a narrative review of the indications, surgical techniques, clinical outcomes, and limitations/complications of microendoscopic decompression for LSS, based on available literature and the authors' experience.
