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.

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.

This study examined radiographic changes in local and global spinal alignments and clinical outcomes following tumor resection without spinal fixation in patients with lumbar dumbbell tumors (LDTs). ⋯ Tumor resection without spinal fixation had no substantial impact on local and global spinal alignments and led to satisfactory clinical outcomes, suggesting that spinal fixation may not always be necessary when resecting LDTs.

Endoscopic carpal tunnel release (ECTR) has advantages over open carpal tunnel release (OCTR); however, complications with ECTR are more likely to occur if the surgeon continues the procedure despite encountering difficulties. Techniques to minimize the need for conversion to OCTR have been infrequently discussed in the literature. This study aims to present a technique for performing ECTR without conversion to the open approach and to analyze the reasons for such conversions. ⋯ A thorough subligamentous extrabursal approach is essential for achieving a clear endoscopic view of the TCL and performing ECTR without the need for conversion to open surgery.
