C2 Slope as an Independent Predictor of Cervical Lordosis Loss Following Laminoplasty

Orthopaedic Surgery, Volume 18, Issue 3, Page 569-575, March 2026.
Cervical radiographic measurements demonstrate that the C2 slope is an independent predictor of cervical lordosis loss after laminoplasty, aiding preoperative risk assessment and surgical decision‐making. ABSTRACT Objective Postoperative loss of cervical lordosis remains a common and clinically relevant complication following laminoplasty, negatively ...

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.

Cognitive Projection of Upper Cervical Spinal Cord Cross‐Sectional Area in Multiple Sclerosis

Acta Neurologica Scandinavica, Volume 2026, Issue 1, 2026.
Background Cervical spinal cord atrophy, typically assessed via measurements of the mean upper cervical cord area (MUCCA), is a significant factor in disability and disease progression in multiple sclerosis (MS). Aim This study is aimed at exploring the relationship between MUCCA, physical disability, and cognitive impairment in MS.

Treatment of Atlantoaxial Rotatory Fixation.

Orthopedics & Traumatology, 2003
This study was counducted on 41 patients with atlantoaxial rotatory fixation (AARF) consisting of 24 males and 17 females, whose age ranged from 3 to 26 years with an average age of 7.1 years, and who were seen at our hospital zero to 53 days after AARF onset.

Bilateral C1-C2 transarticular screw and C1 laminar hook fixation and bone graft fusion for reducible atlantoaxial dislocation: a seven-year analysis of outcome. [PDF]

PLoS ONE, 2014
BACKGROUND: Bilateral C1-2 transarticular screw and C1 laminar hook fixation was developed on the basis of transarticular screws fixation. The modified technique has showed a better biomechanical stability than established techniques in previous study ...

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.
