To study the effect of lumbar lordosis change and pelvic parameters on surgical outcomes such as fusion vs. non-fusion (pseudarthrosis), Adjacent Segment Pathology (ASP), and re-operation in patients undergoing 1-, 2- and 3-level PLF. ⋯ Better restoration of lumbar lordosis reduces rates of pseudarthrosis after short-segment PLF but has no association with rates of ASP.

Radiographic methods for evaluating skeletal maturity traditionally include the Risser sign and the hand-wrist maturation method. While the cervical vertebral maturation (CVM) stage is widely recognized in orthodontics, its application in assessing spinal growth, particularly in adolescent idiopathic scoliosis (AIS), has been less explored. This study explores the correlation between CVM, chronological age, and the Risser sign to evaluate the feasibility of CVM in assessing skeletal development in adolescents. ⋯ The CVM stage, which shows a strong correlation with Risser sign grading, could serve as a reliable alternative for assessing skeletal maturity in adolescent subjects, particularly in clinical scenarios where minimizing radiation exposure is a priority.

Aneurysmal subarachnoid hemorrhage (aSAH) has an incidence of 6-7 per 100,000 person-years. Despite advancements in treatment, 26% of patients die, and 19% remain dependent post-hemorrhage. Long-term neuropsychological sequelae affect about half of the survivors, significantly impacting their quality of life. This study aims to assess aSAH characteristics and identify predictive factors of clinical outcomes in young patients. ⋯ Young aSAH patients exhibit distinct characteristics and prognostic factors compared to older patients. Despite higher post-operative complications, young patients generally have better outcomes, emphasizing the need for age-specific management strategies in aSAH.

Thoracic ossification of the posterior longitudinal ligament (T-OPLL) causes myelopathy. Although posterior decompression for T-OPLL has shown positive results, patients with kyphotic curvatures often endure poor outcomes. Posterior decompression with fusion (PDF) has demonstrated better results compared to posterior decompression alone. This study aims to evaluate the effects of the posterior procedures for T-OPLL. ⋯ Effective management of intervertebral mobility and the appropriate length of decompression are crucial for addressing the thickness and mobility of T-OPLL.

To investigate the factors for pulmonary embolism (PE) development and the necessity of inferior vena cava (IVC) filter placement. Specifically, propose a scoring system to identify patient populations who benefit from IVC filter placement. ⋯ The risk of PE is relatively low after long-segment posterior thoracolumbar fusion. Smoking (former and current), history of cocaine/cannabis use, and history of venous thromboembolism are risk factors in such patients. We recommend prophylactic IVC filter use only in high-risk subgroups and under discretion between physician and patient in medium-risk subgroups.
