BACKGROUND: Although previous literature has described the relevant anatomy for an open anterior Bankart approach of the shoulder, there is little known regarding the anatomic relationship changes in the neurovascular structures after an open Latarjet procedure. PURPOSE: To define the neurovascular anatomy of the native shoulder in relation to the coracoid and to define the anatomy after the Latarjet procedure in relation to the glenoid to determine distances to these neurovascular structures with and without neurolysis of the musculocutaneous nerve (MCN) from the conjoint tendon...

The field of three-dimensional printing applied to patient-specific simulation is evolving as a tool to enhance intervention results. We report the first case of a fully simulated percutaneous coronary intervention in a three-dimensional patient-specific model to guide treatment. An 85-year-old female presented with symptomatic in-stent restenosis in the ostial circumflex and was scheduled for percutaneous coronary intervention. Considering the complexity of the anatomy, patient setting and intervention technique, we elected to replicate the coronary anatomy using a three-dimensional model...

AIM: to compare two methods for quantitative assessment of the proliferative activity index (PAI): a visual estimation method by several investigators and digital image analysis (DIA). The use of the Ki-67 index in the daily clinical practice of a Morbid Anatomy Department is associated with the problem of reproducibility of quantitative assessment of the Ki-67 PAI. Due to the development of digital imaging techniques in morphology, new methods for PAI evaluation using the DIA are proposed...

OBJECTIVE: Muscle variants are common findings in dissection laboratories. These anomalous structures can be relevant in the diagnosis and management of certain conditions and therefore could be incorporated into anatomy curricula at chiropractic colleges. We aimed to create an online resource of muscle variants to facilitate student self-directed learning within this area of study. METHODS: At the time of their discovery during routine educational dissection, muscle variants included in the catalog were documented and subsequent case reports written...

PURPOSE: Critically evaluate the published literature related to quadriceps tendon (QT) medial patellofemoral ligament (MPFL) reconstruction. RECENT FINDINGS: Hamstring tendon (HT) MPFL reconstruction techniques have been shown to successfully restore patella stability, but complications including patella fracture are reported. Quadriceps tendon (QT) reconstruction techniques with an intact graft pedicle on the patella side have the advantage that patella bone tunnel drilling and fixation are no longer needed, reducing risk of patella fracture...

In the mammalian lower urinary tract, there is a reciprocal relationship between the contractile state of the bladder and urethra. As the bladder fills with urine, it remains relaxed to accommodate increases in volume, while the urethra remains contracted to prevent leakage of urine from the bladder to the exterior. Disruptions to the normal contractile state of the bladder and urethra can lead to abnormal micturition patterns and urinary incontinence. While both the bladder and urethra are smooth-muscle organs, they are differentially contracted by input from cholinergic and sympathetic nerves, respectively...

Studies have shown that practicing temporally spaced retrieval of previously learned information via formal assessments increases student retention of the information. Our objective was to determine the impact of online homework administered as a first retrieval practice 1 or 5 days after introduction of physiology topics on long-term information retention. Students in two undergraduate courses, Anatomy and Physiology (ASCI 240) and Animal Physiological Systems (ASCI 340), were presented with information on a specific physiological system during each weekly laboratory and then completed an online homework assignment either 1 or 5 days later...

Surgical resection of an oral tumour (and the associated free flap reconstruction) can significantly alter the oral anatomy. The lack of sulcus depth, alveolar ridge, presence of a mobile flap and limited tongue movement can make it impossible for patients to control a removable prosthesis. To help this cohort of patients, dental implants can be invaluable. The Oral Rehabilitation Team at Central Manchester University Dental Hospital have used dental implants to rehabilitate oral cancer patients for over thirty years...

INTRODUCTION: modern, three-dimensional (3D) anatomy software is a promising teaching method, though few studies examine its effectiveness on upper limb and musculoskeletal anatomy learning. The purpose of this study is to investigate which method is associated with a better outcome, as assessed by students' performance on examinations, when comparing learning with prosections to the use of 3D software. MATERIALS AND METHODS: two groups of undergraduate, first-year medical students without previous knowledge of anatomy were compared...

Background: Workers in pathology and anatomy laboratories may be exposed to formaldehyde. An evaluation of the early effects of this substance is, therefore, paramount. This preliminary study was conducted to evaluate if nasal cytology could be used as a tool to detect changes in nasal mucosa in workers exposed to formaldehyde. Aims: To assess whether nasal cytology was able to reveal any alteration of nasal mucosa in workers exposed to formaldehyde compared to unexposed subjects, and to ascertain whether a specific pattern of alterations correlated with years of exposure in order to evaluate long-term occupational exposure effects...

Bodysnatching was an illegal way to procure cadavers for anatomical dissection before the existence of effective anatomy legislation. As knowledge of anatomy was fundamental to medical practice, many famous 19th century physicians turned a blind eye to this activity or even participated. Sir William Osler, perhaps the most revered physician of all time, received his medical degree from McGill University in 1872 and then served as pathologist at Montreal General Hospital from 1874 to 1884, where he began a career which culminated in him becoming both the first Professor of Medicine at Johns Hopkins and then Regius Professor at Oxford...

While prior meta-analyses in anatomy education have explored the effects of laboratory pedagogies and histology media on learner performance, the effects of student-centered learning (SCL) and computer-aided instruction (CAI) have not been broadly evaluated. This research sought to answer the question, "How effective are student-centered pedagogies and CAI at increasing student knowledge gains in anatomy compared to traditional didactic approaches?" Relevant studies published within the past 51 years were searched using five databases...

This article shows that the academic and research careers of Henry Herbert Donaldson (1857-1938) were directed to provide basic information about the growth of the vertebrate nervous system and to provide standards and the means to make such research efficient. He earned the reputation of making the albino rat a standard laboratory animal. His academic career began when he was an undergraduate at Yale University in 1875 and concluded with his death as Professor and Head of the Department of Neurology at the Wistar Institute of Anatomy and Biology of the University of Pennsylvania in 1938...

In the following editorial commentary, the lateral soft tissues responsible for resisting the pivot shift phenomenon with the anterior cruciate ligament (ACL) are considered. The recent history of the anterolateral ligament (ALL) has led to rapid adoption of surgical techniques that have often not been investigated with scientific due process. A step-by-step approach starts with biomechanical testing to establish the anatomy and biomechanical characteristics of soft tissue structures and questions the importance of the ALL and proposes a more important role for the iliotibial band (ITB) passing between attachments to the distal lateral femur and tibia...

BACKGROUND: Comparative studies of neuroanatomy and neurodevelopment provide valuable information for phylogenetic inference. Beyond that, they reveal transformations of neuroanatomical structures during animal evolution and modifications in the developmental processes that have shaped these structures. In the extremely diverse Arthropoda, such comparative studies contribute with ever-increasing structural resolution and taxon coverage to our understanding of nervous system evolution...
