Endoscopic‐Assisted Posterior Atlantoaxial Fusion: Technical Innovation and Clinical Experience

Orthopaedic Surgery, Volume 18, Issue 8, Page 1768-1782, August 2026.
Endoscopic‐assisted posterior atlantoaxial lateral mass fusion is introduced as a novel minimally invasive technique for treating atlantoaxial instability. The approach enables direct visualization, precise fixation, and effective bone fusion while minimizing muscle dissection, blood loss, and postoperative pain, achieving rapid neurological and ...

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

Annals of Clinical and Translational Neurology, Volume 13, Issue 3, Page 504-516, March 2026.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)

Current Trends in Management of Atlantoaxial Dislocation [PDF]

Orthopaedic Surgery, 2015
Atlantoaxial dislocation (AAD), often caused by trauma, tumors or congenital malformations, is a challenging disorder of the craniocervical junction. Because of its deep location and intricate anatomic structure, the craniocervical junction is always a difficult region for spine surgery.

Anterior Transoral Odontoid Reduction With Clivocervical Fusion in Revision Surgery for Craniovertebral Junction Anomalies: A Case Report and Technical Note

Orthopaedic Surgery, Volume 18, Issue 1, Page 194-201, January 2026.
For revision CVJAs with persistent ventral compression after failed posterior fixation, anterior transoral odontoid reduction combined with clivocervical fusion achieved direct decompression, restored clivo‐axial angle, resolved spinal cord compression, and provided stable fusion with significant neurological recovery, offering an effective salvage ...

Comparison of Two Posterior Minimally Invasive Approaches for Odontoid Fractures: Midline Nuchal Ligament Approach vs. Paramedian Muscle‐Splitting Approach

Orthopaedic Surgery, Volume 18, Issue 1, Page 74-83, January 2026.
The midline nuchal ligament approach yields clinical outcomes similar to those of the paramedian muscle‐splitting technique for odontoid fractures, while offering a more stable surgical procedure and reducing iatrogenic injury to the cervical posterior muscles and the greater occipital nerve.

Morphometric Evaluation of the Craniovertebral Junction Using Computed Tomography: A Sex‐Based Analysis of 500 Adults

BioMed Research International, Volume 2026, Issue 1, 2026.
Background and Objective The anatomy of the craniovertebral junction (CVJ) varies considerably across populations, yet comprehensive Turkish‐specific morphometric data remain limited. We aim to establish normative CVJ measurements in Turkish males and females using computed tomography (CT). Study Design Retrospective morphological study.
