The authors analyzed the current-intensity thresholds for electrostimulation of language fasciculi and the possible consequences of threshold variability on brain mapping. ⋯ Individual variability of minimum stimulation-intensity thresholds for identification of language fasciculi is frequent. Nevertheless, even when a high current intensity was used, many stimulations on language fasciculi remained negative for various hypothetic reasons. Finding the optimal current intensity for identifying language fasciculi is of paramount importance to refine the clinical results and scientific data derived from brain mapping.

To determine whether operative duration of anterior cervical discectomy and fusion (ACDF) significantly affects patient-reported outcome measures (PROMs) 90 days after surgery and at 1-year follow-up. ⋯ All groups improved after ACDF regardless of surgical duration. Further, surgical duration was not a predictor of differing improvement in physical function or disability.

The features of lumbar curves in patients with lumbar spondylolisthesis (LS) are unclear. The aim of this retrospective study was to present the clinical and radiologic characteristics of scoliosis due to LS and LS concurrent with main thoracolumbar/lumbar adolescent idiopathic scoliosis (AIS). ⋯ Lumbar scoliosis may develop due to LS, or a concurrent condition to LS. LL and C-DAR are the features that differentiate AIS from functional scoliosis in patients with LS.

The Tubridge flow diverter (FD) (MicroPort Medical Co. Ltd., Shanghai, China) is a novel device aimed at reconstructing the parent artery and eliminating the aneurysm. Numerical simulations based on virtual FD deployment allow the assessment of the complex nature of aneurismal flow changes before the actual intervention but are demanding on computational resources. Here, we evaluate an alternative strategy of modeling FD effects for the Tubridge system using a porous medium. The goal of this study is to reduce demands on time and complexity of the simulation procedure for applications in clinical research. ⋯ Using a porous medium approach yields comparable mean values for hemodynamic alterations compared to direct virtual FD simulations. Additionally, the porous medium approach greatly reduced the modeling complexity and computation time.

Percutaneous endoscopic lumbar discectomy (PELD) has become a favorable surgical approach for lumbar radiculopathy caused by intervertebral disc herniation. Studies have revealed patients with type II Modic change may suffer from unrelieved low back pain and higher lumbar disc herniation (LDH) recurrence after herniated nucleus pulposus removal. Therefore, in this study, we aim to evaluate how PELD performed in management of LDH patients with type II Modic change. ⋯ PELD performed well in management of LDH patients. However, we need to pay more attention to the continuous low back pain and the recurrence possibility in the cases with type II Modic change. In these cases, longer brace support or other interventions could be applied.
