Original Article - Craniovertebral realignment for basilar invagination and atlantoaxial dislocation secondary to rheumatoid arthritis [PDF]

open access: yes, 2004
Objective: We present our experience of treating nine consecutive cases of rheumatoid arthritis involving the craniovertebral junction by atlantoaxial joint manipulation and attempts towards restoration of craniovertebral region alignments.

Eco‐Innovation Among Environmental Small and Medium Enterprises: A Complexity Theory View on a Regional Paradox

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Environmental entrepreneurship and eco‐innovation, although cornerstones in the transition to a sustainable world, form a research nexus that remains largely understudied. We draw on the theory of complexity and the notion of cultural, temporal, and relational complexities to explain the process of eco‐innovation among environmental small ...

Chiari I Malformation: Review and Update of Current Treatment Options

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The pathophysiology of Chiari malformation type I (CM‐I) is complex, involving structural abnormalities at the craniovertebral junction that result in herniation of the cerebellar tonsils through the foramen magnum. In this study, we aim to present and evaluate current treatment options for CM‐I, with a focus on evidence‐based clinical ...

Direct Intraoperative Reduction of Basilar Invagination Associated with Atlantoaxial Subluxation – Technical Note

open access: yes, 2017
In the present article, we describe a technique of direct intraoperative reduction of congenital atlantoaxial subluxation associated with severe basilar invagination and atlas assimilation. It consists of a wide dissection of the craniovertebral junction,

Developmental Morphometry of the Paranasal Sinuses in Subjects Aged 1–25 Years: A Computed Tomography Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The present study aimed to evaluate the developmental morphometry of the paranasal sinuses using computed tomography (CT) in subjects aged 1–25 years and to characterize age‐related changes in sinus dimensions, volume, and surface area throughout childhood, adolescence, and young adulthood.

Torticollis and rotatory atlantoaxial dislocation: A clinical review

open access: yesJournal of Craniovertebral Junction and Spine, 2019
Rotatory atlantoaxial instability can manifest as an acute episode following subtle or minor injury or even following a gentle tap on head in young children and can manifest as a painless deformity of the head.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Technical Report - Atlantoaxial joint distraction for treatment of basilar invagination secondary to rheumatoid arthritis

open access: yes, 2005
We present our experience of treating two cases of rheumatoid arthritis involving the craniovertebral junction and having marked basilar invagination by an alternative treatment method.

Role of SoxE transcription factors in development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Endoscopic endonasal resection of the odontoid process as a standalone decompressive procedure for basilar invagination in Chiari type I malformation.

open access: yes, 2011
peer reviewedBACKGROUND: The expanded endonasal approach of the cranio-cervical junction provides comfortable working space while avoiding some of the disadvantages of the transoral route. We report a purely endonasal endoscopic resection of the odontoid
