Epistemological Anatomy: A Conceptual Framework for Understanding Anatomical Knowledge

Anatomy is often regarded as settled knowledge. Yet anatomical propositions differ enormously in their evidentiary foundations, while textbooks and atlases frequently present them with similar certainty. How, then, does an anatomical observation become anatomical knowledge? We in...

Does an alar ligament tubercle exist? Anatomical study with application to imaging interpretation and skull base approaches

Although numerous anatomical and radiological studies describe a "tubercle" of the alar ligaments at the medial OC as the alar ligament insertion, no systematic osteological investigation has evaluated the prevalence, morphology, and variability of this structure. Therefore, this...

Distinct fascicular and epineurial architecture of the obturator nerve: a comparative analysis with clinical and surgical relevance

Peripheral nerves of the lumbar plexus share a common origin but exhibit distinct anatomical and clinical features.Although the gross anatomy of these nerves has been described, differences in cross-sectional structure remain unclear.This study compared the histological architect...

Intermuscular Fusion Between the Psoas Major and Iliacus Muscles: Anatomical and Histological Study

Abstract Introduction The term iliopsoas has recently been questioned because some anatomical studies have revealed that the psoas major and iliacus have separate distal insertions. Additionally, some older references mention a more proximal intermuscular fusion. Therefore, the a...

Vancomycin optimised dosing regimens for critically ill patients receiving renal replacement therapy

Optimal dosing of vancomycin in critically ill patients receiving renal replacement therapy (RRT) is uncertain due to high pharmacokinetic variability. We aimed to develop individualised vancomycin dosing recommendations that optimise efficacy while minimising toxicity. Prospecti...
