Multicenter External Validation of the Accuracy of Computed Tomography Criteria for Detecting Thoracolumbar Posterior Ligamentous Complex Injury.

Background And Objective: Recent studies have proposed computed tomography (CT) criteria for posterior ligamentous complex (PLC) injury: disrupted if ≥2 CT findings, indeterminate if single finding, and intact if 0 CT findings. The study aims to validate the CT criteria for PLC injury externally.

Methods: Three level 1 trauma centers enrolled 614 consecutive patients with acute thoracolumbar fractures (T1-L5) who received CT and MRI.

Mortality in patients older than 65 years undergoing surgery for degenerative lumbar spine disease: a comparison with the general population.

Background: The increased life expectancy and prevalence of spondylarthrosis have led to a growing frequency of spinal surgery in older people. This study aims to assess whether there is an excess mortality concerning that expected in the general population associated with surgical procedures performed in patients over 65 years old for a degenerative disease of the lumbar spine.

Methods: All patients aged 65 years or older undergoing surgery at a single center between 2009 and 2019 for lumbar spine degenerative disease were included.

Video-based lecture engagement in a flipped classroom environment.

Purpose: to analyze which factors are associated with students' engagement and participation in video-based lectures in a flipped classroom environment.

Methods: A single-center experience with video-based lectures in undergraduate medical education is described. The activity was applied to the subject of Neurosurgery during two consecutive courses (2021/22 and 2022/23).

Vertebral compression fractures: pain relief, progression and new fracture rate comparing vertebral augmentation with brace.

Background: Osteoporotic vertebral compression fracture (VCF) is the third most frequent fragility fracture in the world. Conservative treatment, vertebroplasty, and kyphoplasty are all recognized therapies. However, diagnostic and therapeutic recommendations must be more consistent when comparing clinical guidelines.
