Background: A large variety of spinal meningeal diseases have been described in the literature, and differential diagnosis is often complex, requiring a good knowledge of the different entities and accurate neuroimaging. The purpose of this article was to depict the most relevant diagnostic features on the commonly utilized MRI sequences for the main and most frequent pathologies of the spinal arachnoid and to correlate them with intraoperative findings.
Material And Methods: Five cases harboring each different spinal meningeal diseases were analyzed, illustrated, extensively described, and discussed: arachnoid web, arachnoiditis, idiopathic spinal cord herniation, intradural arachnoid cyst, extradural arachnoid cyst.
Objective: Posterior Interbody fusion can be associated to adjacent segment disease (ASD) some years after surgery. The aim of this study is to confirm the rate of ASD in isthmic spondylolisthesis treated by posterior fusion.
Methods: Patients treated by posterior lumbar fusion were collected between January 2014 to June 2022.
Background: Congenital craniovertebral junction anomalies (CCVJAs) encompass a diverse range of conditions characterized by distorted anatomy and significant variation in the pathways of neurovascular structures. This study aims to assess the safety and feasibility of tailoring posterior fixation for CCVJAs through intraoperative CT-based navigation.
Methods: An in-depth retrospective analysis was conducted on eight patients diagnosed with CCVJAs (excluding Arnold-Chiari malformation).
