Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

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

The 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,

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Rare case of the fracture of the lateral border of the scapula associated with lesion of the brachial plexus: a case report

The Pan African Medical Journal, 2016
Scapular fractures are considered a very unusual injury, among studies in adults they account for 1-3% of all fractures, and 5% of fractures involving the shoulder, because the anatomic location and the soft tissues protect the scapula.

Integrating whole‐bone and regional analyses to understand human scapular growth

The Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

A RARE CASE OF PEDUNCULATED OSTEOCHONDROMA OF THE DORSAL SURFACE OF SCAPULA

National Journal of Medical Research, 2019
Osteochondromas constitute 30-40 % of all benign bone tumours and is commonly seen at growing ends of long bones. However rarely they are seen in flat bones like scapula, pelvis, skull, scapula, small bones, etc.

Bony Union in Maxilla and Mandible Free Flap Reconstruction: A Systematic Review and Meta-Analysis. [PDF]

Head Neck
ABSTRACT Background Bony nonunion is an important complication in head and neck reconstruction, but its definition, incidence, and treatment are not well‐reported. Methods MEDLINE, Embase, CENTRAL, and Web of Science were searched from October 1st, 1990 to January 6th, 2025 for studies reporting bony union for maxilla or mandible reconstruction with ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Chest wall – underappreciated structure in sonography. Part I: Examination methodology and ultrasound anatomy

Journal of Ultrasonography, 2017
Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of ...

Morphometric analysis of the acromion process of the scapula

CHRISMED Journal of Health and Research, 2020
Context: This study was done to analyze the morphometric parameters of the acromion process of human scapulae. The knowledge of morphometry of acromion process is vital for orthopedic surgeons while performing surgeries like acromioplasty for the ...
