Traumatic posterior atlantoaxial dislocation without an associated fracture: a PRISMA-compliant case-based systematic review and meta-analysis.

Traumatic posterior atlantoaxial dislocation (TPAD) without an associated fracture is a rare and challenging spinal injury. This PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-compliant case-based systematic review and meta-analysis aimed to comprehensively explore TPAD, covering clinical presentation, diagnosis, treatment, and clinical and radiological outcomes. Following the presentation of a case of TPAD without an associated fracture, we conducted a systematic search of electronic databases, including Scopus, PubMed, and Web of Science, from inception through October 2023, without language restrictions.

Posterolateral Fusion Versus Posterior Lumbar Interbody Fusion for Adult Low-Grade Isthmic Spondylolisthesis: Analysis of Sagittal Radiographic Parameters - A Randomized Controlled Trial.

Study Design: Randomized controlled trial.

Objectives: To compare the effect of posterolateral fusion (PLF) and posterior lumbar interbody fusion (PLIF) on sagittal radiographic parameters in patients with low-grade isthmic spondylolisthesis. Additionally, to explore the correlation between changes in these parameters and clinical outcomes.
