The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

open access: yesThe Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

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 ...

Odontoid screw fixation of a type II odontoid fracture in a patient with autofused C2–C3 vertebral bodies

open access: yesInterdisciplinary Neurosurgery, 2018
Background: Anterior odontoid screw fixation for the treatment of type II odontoid fractures, in contrast to posterior C1–2 fusion, allows for maintenance of cervical rotatory motion at C1–2. The approach requires an accessible C2–3 disc space from which

Photogrammetric Reconstruction of 3D Human Anatomical Structures and Augmented Reality via Smartphone Technology

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Limited access to cadavers necessitates the availability of digital resources for anatomy education. Smartphone‐based photogrammetry offers a promising solution for creating three‐dimensional (3D) and augmented reality (AR) models. This study compared two mobile photogrammetry applications (Qlone and Polycam) that have been used in modern ...

Odontoidectomy through posterior midline approach followed by same sitting occipitocervical fixation: A cadaveric study

open access: yesJournal of Craniovertebral Junction and Spine, 2017
Object: Atlantoaxial instability with irreducible odontoid process is one of the challenges in spine surgery. These lesions are commonly treated through anterior transoral approach which is followed by posterior atlantoaxial fusion.
