Summary: This study investigates the relationship between hamstring tightness, lumbar lordosis, and trunk flexibility in healthy adults, focusing on gender differences. Results show significant correlations between trunk flexibility and hamstring tightness in females, while no significant correlations were found in males. Additionally, there were no significant correlations between lumbar lordosis and hamstring tightness in both genders. Significant differences were also observed between males and females in hamstring flexibility, trunk flexion flexibility, and lumbar lordosis.

Summary: This study found that preoperative sagittal misalignment does not significantly affect the correction of alignment after lateral lumbar interbody fusion (LLIF) surgery in patients with lumbar degenerative diseases. However, postoperative low back pain, leg pain, and leg numbness may be improved regardless of the preoperative sagittal alignment.

Summary: The study conducted a prospective observation of 25 patients with spinal deformities, revealing that the location of the lumbar apex can change with different postural positions, but remains stable when assessed as the furthest point of global lumbar lordosis. These findings can help in assessing compensation of lumbar lordosis and guide lumbar lordosis molding in ASD surgery.

Summary: For patients with concurrent KOA and LSD, preoperative TKA combined with spinal fusion surgery can lead to improved radiological and clinical outcomes postoperatively, especially benefiting those with severe abnormalities in sagittal spinopelvic parameters.

Summary: This review aimed to report the prevalence of coexisting lumbar spinal stenosis (LSS) with knee or hip osteoarthritis (OA) based on clinical and/or imaging case definitions. The prevalence of multimorbid LSS and knee or hip OA ranged from 0% to 54%, depending on the specified index condition and case definitions used. However, the variability in case definitions and the high risk of bias in the included studies limit the comparability and interpretation of the prevalence estimates.

Summary: Lumbar spinal stenosis is a common cause of low back and leg pain in older individuals, affecting approximately 103 million people worldwide. Most cases are treated nonoperatively, but surgery is an effective option for patients who do not improve with conservative management.

Summary: The study aimed to compare changes in radiographical segmental alignment following stand-alone cage insertion and additional posterior fixation in the same OLIF procedure for patients with degenerative spondylolisthesis. Results showed that additional posterior fixation provided better segmental alignment improvement in terms of slip reduction and segmental lordosis compared to stand-alone cage insertion.

Summary: In surgical correction of adult spinal deformity, pelvic incidence-lumbar lordosis plays a key role in restoring normal sagittal alignment, with postoperative lordosis morphology being an important factor in preventing mechanical complications. Optimal alignment was achieved in 85.5% of patients, with postoperative PI-LL significantly associated with last follow-up sagittal vertical axis, emphasizing the importance of proportional lordosis correction based on individual spinopelvic alignment.

Summary: This retrospective cohort study aimed to determine if intraoperative lumbar lordosis and segmental lordosis coincide with perioperative change in lordosis. The study found that early postoperative radiographs may not accurately reflect the improvement in lumbar lordosis seen on intraoperative radiographic imaging, but they are predictive of long-term lumbar sagittal alignment. Additionally, cage subsidence and allograft resorption have an impact on segmental lordosis, but do not significantly affect lumbar lordosis.

Summary: This study retrospectively analyzed the relationship between rod and spinal shape in adult spinal deformity surgery. The results showed variations between the curvatures of the rod and spine, suggesting that the shape of the rod does not seem to predict the shape of the spine in the sagittal plane.

Summary: This study analysed the factors associated with low back pain (LBP) in patients with symptomatic lumbar spinal stenosis (SLSS). The results revealed that sagittal vertical axis (SVA) and pelvic incidence-lumbar lordosis (PI-LL) were significant predictors for LBP in SLSS.

Summary: The study investigated the effect of surgery on lumbar spinal canal stenosis in relation to locomotive syndrome, finding a significant improvement in physical function after surgery. Older age and postoperative sagittal balance impairment were identified as significant risk factors associated with non-improvement in locomotive syndrome risk level.

Summary: This study aimed to explore characteristics associated with comorbid symptoms of lumbar spinal stenosis (LSS) in people with knee or hip osteoarthritis (OA). The results showed that comorbid LSS symptoms were common in these patients and were associated with specific characteristics, which can be used to guide clinical decision-making.

Summary: This study describes the physiological sagittal alignment of the lumbar spine across different age groups and finds variations in sagittal lumbar profile subtypes among different age groups, providing important guidance for individualized surgical treatment of the spine.
