INTRODUCTION: Back pain is associated with increased lumbar paraspinal muscle (LPM) stiffness identified by manual palpation and strain elastography. Recently, magnetic resonance elastography (MRE) has allowed the stiffness of muscle to be characterized noninvasively in vivo, providing quantitative 3D stiffness maps (elastograms). The aim of this study was to characterize the stiffness (shear modulus, SM) of the LPM (multifidus and erector spinae) using MRE. MATERIALS AND METHODS: MRE of the lumbar region was performed on seven adults in supine position...

Although disparaged by philologists, hybrid words enrich technical and scientific vocabularies. They are common, so, like it or not, they are here to stay. On the other hand, where there are pre-existing purebred compound or affixed words, they should generally be given preference over hybrids. Some adjectives (e.g., laryngeus and sphenoideus) are discussed to illustrate these recommendations. This article is protected by copyright. All rights reserved.

INTRODUCTION: Osteoarthritis mainly affects weight-bearing joints such as the hip and knee and is the most common form of arthritis. Greater muscle atrophy with fatty infiltration of gluteal muscles and decreased hip abduction strength has previously been identified with increasing severity of radiological hip OA. However, it is well documented that radiographic findings of OA do not always correlate with clinical severity. The aim of this secondary analysis was to examine whether atrophy and strength of gluteus maximus (GMax), medius (GMed), minimus (GMin), and tensor fascia lata (TFL) is associated with the clinical severity of OA...

INTRODUCTION: The complex arterial system makes pancreatic interventions technically challenging for surgeons, and interventional radiologists. The arterial variants may alter tumor resecability, and cause complications in arterial embolization. International data on pancreatic blood supply are variable; therefore, we aimed to determine the frequency of variants of pancreaticoduodenal arterial arcades. MATERIALS AND METHODS: Arteries of human abdominal organ complexes (50) were injected with resin mixture, and then corroded...

INTRODUCTION: The locations of gyral landmarks vary among individuals. This can be crucial during local landmark-based mapping of the human cortex, so the aim of the present study was to establish criteria for classifying the morphological variability of the human insula. MATERIALS AND METHODS: The study was conducted on 50 isolated, randomly-selected adult cadaveric hemispheres, fixed in 10% formalin and preserved in 70% ethanol (24 right and 26 left hemispheres)...

INTRODUCTION: During dual plane breast augmentation (DPBA), the costal origin of the pectoralis major (the PM) should be cut to ensure appropriate coverage and positioning of an implant. However, surgeons sometimes make inappropriate planar incisions and insufficient muscular incisions because the external abdominal oblique (the EAO) muscle partially overlaps the lateral portion of the PM. The goal of this study was to clarify the positional relationship between the PM and EAO with the aim of improving the accuracy of implant and muscular incisions during DPBA...

INTRODUCTION: A "perineal" branch of the sciatic nerve has been visualized during surgery, but there is currently no description of this nerve branch in the literature. Our study investigates the presence and frequency of occurrence of perineal innervation by the sciatic nerve and characterizes its anatomy in the posterior thigh. MATERIALS AND METHODS: Fifteen cadavers were obtained for dissection. Descriptive results were recorded.Statistical analysis was performed and analyzed statistically...

Shiby Stephens, Bernard John Moxham
The ability of medical students to acquire anatomical and medical terminologies could be influenced by their knowledge of classical Greek and Latin. In a previous study (Stephens and Moxham, 2016), it was reported that, while newly recruited medical students have a very favourable attitude towards the need to understand these classical languages, final year students see no benefit. In this study, we tested the hypothesis that, regardless of attitude, students in the initial stages of their medical education perform better at both summative and formative anatomy examinations if they have prior knowledge of Greek and Latin...

PURPOSE: We aimed to characterize the agreement between distinct structural changes on magnetic resonance (MR) imaging and self-reported injury in the 12 months leading to incident common or accelerated knee osteoarthritis (KOA). MATERIALS AND METHODS: We conducted a descriptive study using data from baseline and the first 4 annual visits of the Osteoarthritis Initiative. Knees had no radiographic KOA at baseline (Kellgren-Lawrence [KL]<2). We classified 2 groups: 1) accelerated KOA: a knee developed advanced-stage KOA (KL=3 or 4) within 48 months and 2) common KOA: a knee increased in radiographic severity (excluding those with accelerated KOA)...

Deivis de Campos
The specialized literature has described how the great anatomist par excellence, Michelangelo Buonarroti (1475-1564), like many other renowned artists of his time, included a self-portrait in many of his works. This article presents novel evidence that Michelangelo inserted his self-portrait into a sketch of his close friend, Vittoria Colonna (1490-1547). This work, made by Michelangelo in 1525, is currently in the collection of the British Museum in London, England. This self-portrait of Michelangelo can serve as a tool for analyzing the artist's probable bodily dimensions and even his state of health during this period of his life...

Christopher R Newman, William L Walter, Simon Talbot
Introduction The sulcus line (SL) is a three-dimensional landmark that corrects for individual variation in the coronal alignment of the trochlear groove in contrast to the traditional Whiteside's line (WL). Femoral rotational asymmetry (FRA) is an anatomical variation in which the posterior condyles and trochlear groove are not perpendicular to each other. This study aims to measure the SL and assess its reliability relative to WL, in addition to measuring and classifying the FRA. Materials and Methods A retrospective analysis of a series of 191 CT scans of non-arthritic knees was performed...

Mohammed K Khalil, Eiman M Abdel Meguid, Ihsan E Elkhider
Blended learning is the integration of different learning approaches, new technologies and activities that combine traditional face-to-face teaching methods with authentic online methodologies. Although advances in educational technology have helped to expand the selection of different pedagogies, the teaching of anatomical sciences has been challenged by implementation difficulties and other limitations. These challenges are reported to include lack of time, costs, and lack of qualified teachers. Easy access to online information and advances in technology make it possible to resolve these limitations by adopting blended learning approaches...

INTRODUCTION: The minor salivary glands in the retromolar trigone have rarely been studied. The aim of this study was to better define the anatomy of the minor salivary glands in the retromolar trigone and establish the relationships between these and adjacent structures. MATERIALS AND METHODS: The gland in the retromolar trigone was exposed and its relationships to surrounding structures were observed on twenty cadaveric sides. RESULTS: The boundaries of the gland included the superior pharyngeal constrictor muscle, the tendon of the buccinator muscle, and loose connective tissue...

Although the embryology of the posterior cranial fossa can have life altering effects on a patient, a comprehensive review on this topic is difficult to find in the peer-reviewed medical literature. Therefore, this review paper, using standard search engines, seemed timely. The embryology of the posterior cranial fossa is complex and relies on a unique timing of various neurovascular and bony elements. Derailment of these developmental processes can lead to a wide range of malformations such as the Chiari malformations...

In 1891 Hans Chiari described a group of congenital hindbrain anomalies, which were eventually named after him. He classified these malformations into three types (Chiari malformations I, II, and III), and four years later added the Chiari IV malformation. However, numerous reports across the literature do not seem to fit Chiari's original descriptions of these malformations, so researchers have been encouraged to propose new classifications to encompass these variants (e.g., Chiari 0, Chiari1.5, and Chiari 3...

INTRODUCTION: Left-hemispheric ischemic strokes are more frequent overall and often have a worse outcome than their right-hemispheric counterparts. We hypothesized that the right-left propensity of CE cerebral infarcts differs between patients with standard and bovine arch variants. METHODS: We retrospectively identified all patients with acute stroke of the anterior circulation admitted to our primary stroke center between January 2011 and June 2017 who had moderate- to high-risk cardio-embolic sources according to the SSS-TOAST classification...
