This study aimed to identify surgical, patient-specific, and radiographic risk factors for proximal junctional failure (PJF), a complex complication following adult spinal deformity (ASD) surgery. ⋯ In ASD patients, the presence of concurrent osteoporosis or paravertebral muscle wasting significantly increases the risk of developing PJF. The use of bicortical screws, UIV screw angle exceeding 1°, and positioning the UIV in the lower thoracic or lumbar region also further elevate this risk. Lower preoperative SS, higher preoperative PI-LL, higher preoperative pelvic tilt, higher preoperative SVA, higher postoperative LL, and a greater change in LL characterize patients with PJF.

Posterior ring apophysis separation (PRAS) associated with lumbar disc herniation (LDH) is a relatively rare form of disc herniation. This study aims to evaluate the clinical effectiveness of unilateral biportal endoscopic discectomy (UBE) and percutaneous endoscopic lumbar discectomy (PELD) in the treatment of PRAS with LDH. ⋯ UBE and PELD possess strong clinical effectiveness for treating PRAS with LDH. Although the UBE group had a longer mean operative time and LOS, with more Hb loss, the UBE group had a lower recurrence rate. Therefore, UBE remains safe and innovative for the treatment of PRAS with LDH.

A profound knowledge of the anatomy and surgical management of the superior petrosal vein is vital during neurosurgical procedures in the posterior fossa. The debate on preserving the superior petrosal vein or whether it can be duly obliterated is still ongoing. ⋯ Not only were the heterogenous methods but also the respective authors' conclusions analyzed. In light of the collected evidence, we come to the conclusion that occluding the superior petrosal vein poses an ineligible risk to patient safety and should be considered obsolete.

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.
