Article
The morphology of the vascular supply of peripheral branches of cardiac nerves has not been systematically described until now. The aim of this study was to describe the architectonics of the vasa nervorum of epicardial nerves in porcine hearts by using two injection techniques. Twenty‐three hearts from young healthy pigs were used. In ten hearts I...

Introduction: The goal of this study was to investigate prevalence and morphometric parameters of pubic ligaments and the interpubic disk and its cavity using imaging methods for use in clinical medicine. Methods: Pubic symphysis morphology was investigated in 652 patients (348 women and 304 men), from which 449 CT scans and 203 MR scans were av...

Restoring shoulder abduction is one of the main priorities in the surgical treatment of brachial plexus injuries. Double nerve transfer to the axillary nerve and suprascapular nerve is widely used and considered the best option. The most common donor nerve for the suprascapular nerve is the spinal accessory nerve. However, donor nerves for axillary...
Article
The anatomy of the biceps brachii muscle has been a subject of interest to many researchers. In particular, the presence of one or more accessory heads has been reported to be the most common variation of the biceps brachii muscle. In fact, contemporary knowledge is quite inconsistent and lacks a definitive summary. Taking this into account, the pr...

Background /Objectives: The dorsal pancreatic artery is the main artery of the body and tail of the pancreas. Its origin and branching is highly variable. The aim of this study was to perform a meta-analysis to generate pooled prevalence data on the presence and origin of the dorsal pancreatic artery. Clinically important aspects of the dorsal panc...
Article
Every surgeon starts the training with suturing, which can be very confusing as most of the senior surgeons have their own style, approach, tricks and different rules to follow. It is hard for residents and medical students to know what is an evidence-based rule that should be followed and what is a personal trick of their teacher that can be modif...

Johannes Jessenius or Ján Jesenský (1566–1621) can be considered as a contradictory and inconsistent personality of the early modern history. Being not only a physician, but also scientist, teacher, philosopher and even historian and politician, he definitively ranks among the outstanding polymaths of his time in the region of Central Europe. His s...
Article
BACKGROUND This report depicts a rare case of acutely developed urinary retention as well as sensory and motor disturbances caused by formation of a large hematoma within the piriformis muscle, which caused compression of nerves within the suprapiriform and infrapiriform foramina, thus imitating cauda equina syndrome. Although cases of acute lumbos...

Introduction: Thrombolysis has been suggested as a feasible method to treat arterial renal transplant thrombosis under conditions of short duration of ischemia. Data on maximal duration of ischemia that are still feasible to treat are scarce. Methods: We retrospectively analysed our experience involving three attempts to utilize thrombolysis to tr...

Ameloblastoma is a benign odontogenic tumor characterized by slow growth causing painless facial swelling. The tumor can behave locally aggressively, and may have direct destructive effects on the surrounding soft and hard tissues. This paper reports the unique case of a female patient with giant ameloblastoma of the mandible. Computed tomography (...

Background and Objectives: Angular projection measurements have long been an established approach in anatomical morphometry. However, many described projection angles are in reference to inherently curved structures, often oversimplifying their topologies. Measuring the curvature of a structure allows for a more accurate description of the structur...

Purpose The structure of the proximal margin of the superficial layer of the supinator muscle is of high interest to many researches. Its tendinous appearance, called the arcade of Frohse, may be clinically important because of its close relationship to the deep branch of the radial nerve passing beneath it and is considered to be the cause of seve...

PurposeVariations of the peripheral nervous system in the upper limb, especially of the musculocutaneous and median nerves, are common, but closer attention to the knowledge of the variant anatomy should be paid to avoid iatrogenic injury or to understand the unusual clinical signs.Methods During a routine dissection course, bilateral variations we...
Article
Introduction: Great variability in shape and size of the bony pelvis can be observed in the current population, but there is not enough data on how long the historical period must elapse to gain changes in pelvic shape and size. The aim of the study was to identify morphological changes in bony pelvis in males and females after a developmentally s...
Article
Introduction: The brachial plexus is a complex anatomical structure that gives rise to all the nerves of the upper limb. Its variability is frequently observed and represents a challenge for interventions in the lower neck and axilla. The aim of this study was to present a comprehensive and evidence-based review with meta-analytic techniques on th...

This article is the fourth and last part of a series aimed at extending and correcting the anatomical nomenclature. Because of the rapid development of internet and the use of electronic formats in communication in anatomy, embryology, histology, medical education and clinical medicine, an appropriate, precise and concise anatomical nomenclature is...
Article
We read the case report by Hegazy AA, Hegazy MA (2020), “Unusual case of absence of suprascapular notch and foramen” Eur J Anat, 24 (4): 269-272, addressing an unusual case of absence of suprascapular notch and foramen, with interest. However, we would like to point out that this case is rather a discrete type of suprascapular notch (SSN), and it i...

Introduction The inferior phrenic artery is a paired artery that supplies the diaphragm from its inferior aspect. It may arise as a common trunk, the common inferior phrenic artery (CIPA), or as two individual arteries, the right and left inferior phrenic arteries (RIPA and LIPA, respectively). The aim of this study was to perform a systematic revi...

Variant anatomy, which is an integral part of anatomical science, is related to abnormalities in the human body structure. Our understanding of variant anatomy is based on thousand years of anatomical experience. These abnormalities generally do not interfere with the function of the human body and do not typically manifest as pathological nosologi...

Accessory bones in the region of the elbow are rare variants with high clinical significance as they may be confused with avulsion fractures. We investigated their prevalence and performed a statistical analysis to support their congenital origin. Their localization was mapped to show their exact site of occurrence. We evaluated anteroposterior and...

PurposeThe variability of the recurrent branch (RB) of the median nerve lends itself to an increased risk of injury when performing the minimally invasive approach for carpal tunnel release without its direct visualization. This risk is less so when it is released via the more invasive open approach as the RB can be easily identified, but the drawb...

With the exception of the olfactory and optic nerves, all cranial nerves enter or leave the brain stem. Three of the cranial nerves are purely sensory (I, II and VIII), five are motor (III, IV, VI, XI and XII) and the remaining nerves (V, VII, IX and X) are mixed. The olfactory nerve will be discussed in ► Chap. 14, the optic nerve in ► Chap. 8 and...

We read Grigoriă et al.’s case report “Unusual anatomical variation: tetrafurcation of the celiac trunk”. They report a coeliac trunk giving rise to a common inferior phrenic artery and an accessory left gastric artery before bifurcating into a common hepatic artery and a splenogastric trunk. The terminology they use causes confusion, as they do no...

Introduction: Many widely used international histological textbooks claim that the epithelium of the human uterine tube consists of two, three, and, eventually, four types of cells. Most discrepancies among these textbooks relate to debates regarding the presence or absence of basal cells, whether the peg/intercalary cells and secretory cells are...
