Summary: The study evaluated the sagittal spinopelvic parameters of spondylolysis patients using the EOS imaging system in a Taiwanese population. It found that the pelvic incidence and lumbar lordosis were significantly larger in spondylolytic patients, and high-grade disc degeneration and age were associated with the occurrence of spondylolisthesis. Ethnological differences should be considered in clinical decisions regarding spondylolysis in Taiwanese population.

Summary: The aim of this study was to evaluate the correlation between sagittal and spinopelvic alignment and preoperative patient-reported outcomes (PROs) in degenerative lumbar spondylolisthesis (DLS) with spinal stenosis. The study found that sagittal and spinopelvic malalignment do not appear to significantly influence baseline PROs in patients with DLS.

Summary: Spinal balance refers to the equilibrium between outside forces on the spine and muscle responses of the trunk under sensorineural regulation, to maintain stable upright posture. It is influenced by various factors such as human evolution, skeletal growth, and maturation of postural control centers. While the development of upright posture was crucial for human adaptation, it can also lead to certain spinal pathologies if not properly maintained or restored.

Summary: This study aimed to evaluate the effect of TLIF on surgical treatment of LDS and found that slip reduction helps to improve sagittal alignment. The results showed comparable fusion rate and radiographic outcomes between PLF and TLIF at 2-year follow-up.

Summary: This study aims to propose a quantitative definition of hip flexion contracture and analyze its impact on sagittal alignment. The results demonstrate that patients with hip flexion contracture exhibit a specific pattern of spinopelvic alignment and head position. Although the surgical outcome improves, hip mobility is not always restored.

Summary: This study aims to explore the relationship between spinal alignment and preoperative patient-reported outcomes in patients with degenerative lumbar spondylolisthesis. It was found that increasing age, higher sagittal vertical axis, and global coronal imbalance were independent risk factors for worse preoperative outcomes. Unstable spondylolisthesis and global coronal imbalance were two vital predictors of back pain, and increasing age, local coronal imbalance, and global coronal imbalance were associated with higher leg pain. Patients with coronal imbalance also showed significant sagittal malalignment.

Summary: The presence of degenerative spondylolisthesis (DS) or degenerative lumbar scoliosis (DLS) in patients with lumbar spinal stenosis (LSS) does not significantly affect mid-term clinical outcomes after minimally invasive lumbar decompression surgery. Lumbar decompression without fusion can lead to improved lumbar and sagittal spinopelvic alignment in patients with LSS, even with the coexistence of DS or DLS. Minimally invasive surgery can be considered for most patients with LSS.

Summary: This study analyzed parameters of patients with different types of double-level DLS and found that anterior type patients had more severe symptoms, higher incidence of neurologic symptoms, and significantly higher sagittal spinopelvic parameters compared to other types.

Summary: This review evaluated the relationship between craniocervical posture and sagittal position of the mandible, as well as the risk of bias in the included studies. The findings suggest that increased cervical inclination and head upright position are associated with the posterior position of the mandible.

Summary: Lumbar decompression may be a recommendable surgical option for certain elderly patients with lumbar spinal stenosis and sagittal imbalance, despite less improvement in leg pain compared to fusion surgery.

Summary: This study aimed to examine the sagittal alignment evolution in adult spinal deformity (ASD) over time and found that TK tends to worsen over time for all patients, while TLK preferentially increases in the lower thoracic group. Although several key parameters are maintained over time postoperatively, compensatory changes in PT help maintain overall global alignment.

Summary: A study found that about 25-30% of patients did not achieve the desired spinal alignment after adult spine deformity surgery, indicating the need for advancements to improve surgical outcomes.

Summary: This prospective cohort study aimed to evaluate the associations between preoperative cervical sagittal alignment and health-related quality of life, function, and symptoms in patients with CSM. The study also examined whether surgery leads to changes in cervical sagittal alignment and if postoperative alignment is associated with health-related outcomes at 12 months of follow-up. The results showed that increased cSVA and T1 slope were associated with inferior health-related quality of life at presentation among CSM patients. However, no significant associations were observed between alignment parameters or change in alignment and any measures of health-related quality of life, function, or symptoms at 12 months after surgery. The study suggests that maintaining or improving cervical sagittal alignment may not have a significant impact on patient outcomes following surgical treatment for CSM.

Summary: The study compared clinical outcomes and spino-pelvic sagittal balance treated with OLIF and TLIF for degenerative lumbar spondylolisthesis. Results showed that the OLIF group had better improvement in disc height and foraminal height compared to the TLIF group, and restoration of spino-pelvic sagittal balance was observed in both groups post-surgery.
