Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Fascicle measurement methods do result in lengths that are significantly different

open access: yesThe Anatomical Record, EarlyView.
A recent comparison of the most prevalent methods for measuring fascicles, in situ measurement versus chemical digestion, concluded that the measurements are indistinguishable based on data from different conspecific individuals. However, our study of contralateral muscles of the same individuals shows that the methods clearly result in statistically ...

Descriptive, stratigraphic, and morpho‐functional study of the myocardium and myocardial bridges in domestic pig hearts

open access: yesThe Anatomical Record, EarlyView.
Abstract The heart is the central organ of the cardiovascular system. The myocardium is composed of a three‐dimensional network of fibers arranged in clockwise and counterclockwise helices, which are essential for proper cardiac contraction. This study aimed to describe the stratigraphic and morpho‐functional pattern of the porcine myocardium to ...

Comparative analysis of cytoarchitectonic and neurochemical aspects of the globus pallidus in the rock cavy (Kerodon rupestris) and the common marmoset (Callithrix jacchus)

open access: yesThe Anatomical Record, EarlyView.
Abstract The globus pallidus (GP), a subcortical structure within the basal ganglia, plays a crucial role in modulating cortico‐subcortical circuits related to motor control and associative/limbic functions. However, the cytoarchitectonic and neurochemical organization of this structure remains poorly characterized in naturally existing wild‐type ...

Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

open access: yesThe Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Female Patients Exhibit a Narrower Glenoid Rim and Lower Bone Density in the Anteroinferior Quadrant Compared With Male Patients

open access: yesArthroscopy, EarlyView.
Purpose The purpose of this study was to evaluate sex‐based differences in glenoid rim morphology and bone density relevant to arthroscopic Bankart repair. Methods This retrospective study assessed differences in glenoid rim morphology between sexes in patients with shoulder instability and uninjured control subjects who underwent a magnetic resonance ...

Computed Tomography‐Based Morphometric Analysis Reveals Intercondylar Notch Stenosis and Osteophytes Are Associated With Anterior Cruciate Ligament Injury

open access: yesArthroscopy, EarlyView.
Purpose To quantitatively assess intercondylar notch morphometrics using 3‐dimensional computed tomography reconstruction, evaluate their association with anterior cruciate ligament (ACL) injury in Asian populations, and investigate the prevalence of osteophytes in patients with ACL injury.

Editorial Commentary: The Femoral Impingement Index: Can Composite Morphology Better Capture Femoroacetabular Impingement Syndrome?

open access: yesArthroscopy, EarlyView.
Abstract Hip arthroscopy has undergone remarkable evolution over the past 2 decades. Improvements in patient selection, advanced imaging, labral preservation, capsular management, and osseous correction of femoroacetabular impingement syndrome have translated into consistently favorable outcomes for appropriately selected patients.

Arthroscopic Bankart Repair With a 6 o’Clock Anchor Reduces Recurrence and Improves Clinical Outcomes in Recurrent Anterior Instability

open access: yesArthroscopy, EarlyView.
Purpose To evaluate the clinical effectiveness of placing the most inferior suture anchor at the 6 o'clock position during arthroscopic Bankart repair compared with non‐6 o'clock anchor repair for recurrent anterior shoulder instability. Methods From January 2012 to December 2022, this retrospective study included patients with recurrent anterior ...
