PURPOSE: To analyze the morphometric parameters of the dorsal sacral lamina and pedicles to determine if there is adequate bony architecture to support plate osteosynthesis. METHODS: Two reviewers performed measurements on 98 randomly selected high-resolution CT scans of the pelvis to quantify the bony anatomy of the sacral lamina. Measurements included the depths of the lamina at each sacral level, the trajectory and depth of the sacral pedicles from the sacral lamina, and the width of the sacral canal...

Rarely, the anterior cerebral artery (ACA) arises from the ophthalmic segment of the internal carotid artery, a condition described as carotid-ACA anastomosis or infraoptic course of the ACA that generally demonstrates right-sided predominance. We diagnosed a case of bilateral anastomoses of the carotid and ACA vessels in which bilateral ophthalmic arteries arose from the origins of the anastomotic vessels using magnetic resonance (MR) angiography. Identification of rare arterial variations on MR angiography requires careful scrutiny of source images, and creation of partial volume-rendering images can aid visualization of detailed anatomic structures...

AIM: The rectosigmoid junction is the limit separating the sigmoid colon and rectum. This transition zone has different definitions. We want to highlight different landmarks of the rectosigmoid junction (RSJ), to help the clinicians to adopt a consensual definition. METHOD: We reviewed anatomical, endoscopic, physiological and surgical points of view concerning the rectosigmoid junction (RSJ). RESULTS: The rectosigmoid junction has a different definition depending on who is studying it...

REVIEW
Kaissar Yammine, Mirela Erić
INTRODUCTION: Linburg-Comstock variation often connecting the flexor pollicis longus and flexor digitorum profundus of the index finger at a different level with significant discrepancy between clinical and cadaveric frequencies reported in the literature. Although this variation is quite prevalent, it is yet frequently unrecognized. The aim of this meta-analysis is to generate more accurate weighted frequency values of the Linburg-Comstock variation and to look for possible association with ethnicity, laterality, gender and side...

PURPOSE: The gastro-omental artery (GOA) with the greater omentum (GO) is known for its high quality as a vascular graft, its resistance to infections as an omental flap and for its multiple applications in surgery. A better knowledge of anatomical variations of GO and its vascularization can improve the application in surgery and decrease complications. The purpose of this study was to measure diameters and lengths of the right GOA (RGOA) and study the interindividual variability of these anatomical structures...

A Peyrottes, D Mariage, P Baqué, D Massalou
Median arcuate ligament (MAL) syndrome is a rare and poorly known cause of abdominal pain. MAL narrows the celiac artery (CA), resulting in true distal aneurysms, including pancreaticoduodenal artery (PDA) aneurysms. These aneurysms often have an aggressive course, as rupture can result in hemorrhagic shock. CT scan appears to be the most effective investigation for the diagnosis of PDA aneurysms and may reveal possible celiac artery compression. In this series, we describe four cases of PDA aneurysm: two ruptured aneurysms treated by an endovascular procedure and two non-ruptured aneurysms treated by surgery...

PURPOSE: The greater and lesser palatine nerves and vessels supply the hard and soft palates, and the roots of these vessels and nerves run through a bony structure. However, the arrangement of blood vessels in the maxilla requires attention during clinical treatments, but detailed morphological information about changes in the greater and lesser palatine arteries and nerves during aging is unavailable. We therefore need detailed investigations of the morphology of the donor cadaver palatine using cone-beam computed tomography (CBCT) and macroscopic observations...

BACKGROUND: The 3D architecture of the ventricular mass is poorly known, although in vivo imaging techniques show the physiological inhomogeneity of ventricular walls mechanics. Polarized light imaging makes it possible to quantitatively analyse the myosin filament orientation. AIMS: In this paper, we focus on the study the 3D architecture and regional isotropy of myocardial cells. METHODS: Twenty normal human hearts, 10 from the perinatal period and 10 from the post-neonatal period were studied by polarized light microscopy...

Lionel Benamran, Alain Charles Masquelet
PURPOSE: There is no typical approach for decompression of forearm compartment syndrome, due to contradictory considerations regarding the characteristics of forearm anterior compartment deep fascia. The main purpose of this study was to determine how many fasciae should be opened to fully decompress the forearm anterior compartment. Further, the compliance of the deep anterior compartment was also investigated, to strengthen our results. METHODS: An experimental study of a laboratory model of acute forearm compartment syndrome was performed...

The tibial nerve is the larger terminal branch of the sciatic nerve and it terminates in the tarsal tunnel by giving lateral and medial plantar nerves. We present a rare case of trifurcation of the tibial nerve within the tarsal tunnel. The variant nerve curves laterally after branching from the tibial nerve and courses deep to quadratus plantae muscle. Interestingly, posterior tibial artery was also terminating by giving three branches. These branches were accompanying the terminal branches of the tibial nerve...

INTRODUCTION: According to the anatomical literature, the extensor pollicis brevis (EPB) tendon passes through the first compartment and enters the base of the proximal phalanx of the thumb. There have been a few reports on the different types of supernumerary EPB tendons; however, an unusual course of the EPB tendon is extremely rare. MATERIALS AND METHODS: During routine cadaveric dissection in the Department of Gross Anatomy, we detected an variant EPB muscle in a 96-year-old fresh female cadaver...

Lidija Kocbek, Mateja Rakuša
PURPOSE: The right bronchial artery usually arises from the descending thoracic aorta as a common trunk with the right intercostal artery and forms the right intercostobronchial trunk. Both, the third right posterior intercostal artery and the right intercostobronchial trunk, are described as the most constant vessels. The focus of the study was to determine the characteristics of the right intercostobronchial trunk regarding the origins of the posterior intercostal arteries from the thoracic aorta...

Georg Singer, Robert Marterer, Holger Till, Barbara Schmidt
BACKGROUND: The superficial palmar branch of the radial artery (SPBRA) normally pierces through the thenar muscles and unites with the ulnar artery to form the superficial palmar arch. Rarely, a subcutaneous course of the SPBRA is described in which the artery lies superficial to the thenar muscles. CASE REPORT: We report about a 17-year-old female patient with pain at the thenar eminence due to a unique course of the SPBRA. Duplex sonography and magnetic resonance angiography revealed a subcutaneous course of the artery over the thenar muscles...

PURPOSE: In women, the uterine artery is the main branch of the internal iliac artery, vascularizing most of the uterus. Knowledge of its origin and variations is essential during extensive gynaecological surgery and interventional radiological procedures. We aimed to investigate its origin and explore its anatomical variations by three-dimensional (3D) reconstructed computed tomography (CT) angiography. METHODS: This was a retrospective, monocentric observational study involving CT scans of the abdomen and lower limbs of women < 50 years old with 3D reconstructed CT images of the internal and external iliac arterial axes...

BACKGROUND: Anterior mandibular (interforaminal) region is important in implant applications as it serves a basis for neurovascular bedding and holds the prosthesis for patients. Treatment planning for dental implant patients is often complicated by the unknown extent of the anterior loop of the neurovascular bundle. Anatomical structures including mandibular incisive canal (MIC) and lingual foramen (LF) should also be examined as part of the detailed analysis for their neurovascular structures...
