Background

A knowledge gap exists on how to implement three dimensional (3D) printing and extended reality (XR) technologies in anatomy education. Also, it remains unclear how students experience the implementation of these new technologies in anatomy education,. This report describes the result of an elective course on the use of 3D prints and XR at our Faculty of Medical Sciences.

Methods

A 10-week elective course on the use of 3D prints and XR was organized for undergraduate students studying Medicine and Biomedical Sciences. Students were trained on how to construct 3D models and/or XR models from radiological data. Students received further education on the strengths and limitations of each technique and on how to evaluate scientific literature on this topic. Also, students received training on providing anatomy education using 3D models and/or XR models. The course was evaluated using a specifically designed survey containing twelve questions. Questions needed to be answered using a 5-point Likert scale to rate several topics concerning the course itself, educational elements and perceived study load.

Results

An extensive course description is provided to help other anatomy educators to adopt 3D prints and/or XR models in the curriculum at their institution. Student evaluations indicated that learners found the constructed (virtual) models insightful and highly motivating, which helped them to actively engage in (future) anatomy education.

Discussion

Here presented results encourage the further implementation of 3D models and/or XR models based on radiological data in anatomy education. However, future research on educational effectiveness are needed.

Background

Cross-sectional anatomy is a challenging yet a vital foundation to clinical practice. The traditional teachings of gross anatomy cadaveric dissections do not cover adequate training of recognizing anatomical structures on CT, MRI and sonographic cross-sections. New modern technologies are emerging as teaching tools in anatomy aiming to deliver visual interactive experience. The Visible Human Project provides a library of cross-sectional images compiled from cryosectioned body donors that was utilized by modern technologies such as the virtual dissection table (Anatomage) in constructing 3D software applications visualizing the internal composition of the human body virtually. Hereby, this article explores an integrative approach utilizing the Visible Human Project based applications and basic radiological modalities.

Purpose

The purpose of our newly implemented teaching approach was to test and assure technology fitness to the medical curriculum and its potential influence on students’ performance in learning gross as well as cross-sectional anatomy in much depth.

Basic procedures

A three years (2021–2024) observational study was conducted by implanting a practical cross-sectional anatomy optional course by selectively utilizing Anatmage interactively beside CT, MRI and ultrasound practice. The performance of 50 participants was evaluated in the form of a written test comprised of labeling of ten cross-sectional images and drawing of two cross-section schemes. Their optional course test scores were compared to their obligatory anatomy subject test scores; and to a non-participants control group of 50 retrospective obligatory anatomy subject test scores. In addition, the participants’ attitude toward the training lessons was assessed through a survey focused on satisfaction level, competence and ability to recognize structures on radiological images.

Main findings

The participants reported a high level of practical engagement. The test scores in the anatomy obligatory subject were positively influenced by this implemented practical course. Students showed improved test scores in the standardized labeling keyword questions, while the scheme questions showed discrepancy.

Principal conclusions

Integrating Visible Human Project based applications with radiological modalities showed positive efficacy on the students’ engagement and learning performance. Inevitably, cadaveric dissection and prosection remain the cornerstone of gross anatomy education. Integrating both modalities of teaching would excel students’ practical skills in applied clinical anatomy.
背景:横断面解剖是临床实践中一项具有挑战性的重要基础。传统的大体解剖尸体解剖教学并不包括在 CT、MRI 和超声横断面上识别解剖结构的充分培训。新的现代技术正在成为解剖学的教学工具,旨在提供视觉互动体验。可见人体项目提供了一个从冷冻尸体捐献者身上收集的横截面图像库,该图像库被虚拟解剖台(Anatomage)等现代技术所利用,用于构建虚拟可视化人体内部组成的三维软件应用程序。目的:我们新实施的教学方法旨在测试和确保技术与医学课程的匹配性,以及其对学生深入学习大体解剖学和横断面解剖学的潜在影响:我们进行了一项为期三年(2021 年至 2024 年)的观察性研究,在 CT、MRI 和超声波实践的同时,有选择性地使用 Anatmage 进行互动,植入了实用的横断面解剖选修课程。50 名学员的成绩以笔试的形式进行评估,包括标注十张横断面图像和绘制两个横断面方案。他们的选修课程考试成绩与他们的解剖学必修科目考试成绩进行了比较,并与一个由 50 名回顾解剖学必修科目考试成绩的非参与者组成的对照组进行了比较。此外,还通过一项调查评估了学员对培训课程的态度,调查的重点是满意度、能力和识别放射图像上结构的能力:主要研究结果:学员的实际参与度很高。解剖学必修课程的考试成绩受到了这一实践课程的积极影响。学生们在标准化标签关键词问题上的考试成绩有所提高,而在方案问题上则出现了差异:主要结论:将基于可见人类项目的应用与放射学模式相结合,对学生的参与度和学习成绩产生了积极影响。不可避免的是,尸体解剖和解剖仍然是大体解剖学教学的基石。将这两种教学模式结合起来,可提高学生在临床应用解剖学方面的实践技能。

Background

Plastination preserves biological specimens for long-term and geometric morphometry analyzes shape differences with advanced statistical methods. This study primarily aimed to statistically quantify shrinkage in brain sections following plastination. The secondary goal was to present the shrinkage occurring in both tissues and cavities of specific anatomical structures using geometric morphometry.

Methods

Fourteen sections from each of nine male bovine brains underwent silicone plastination using the standard technique, which involves four stages: fixation, dehydration, forced impregnation, and curing. The shrinkage percentage in plastinated sections was measured using ImageJ, while geometric morphometry was used for shape analysis. Correlation analysis was performed to reveal the relationship between ventricle area and shrinkage percentage.

Results

Significant shrinkage was observed in each brain section. A positive correlation was observed between the shrinkage on the sections and ventricular area. However, with the exception of sections number 2, 5, 9, 12 and 13, this correlation was not statistically significant for the remaining sections. Using geometric morphometric, shrinkage, and associated shape variations in specific anatomical regions within the serial brain sections were illustrated with visual graphics. Shape analysis revealed the most pronounced shrinkage in the sulcus coronalis, sulcus suprasylvius rostralis, ventral surface of the thalamus, and the third ventricle. Additionally, the cornu ammonis (hippocampus) exhibited the most significant shrinkage and shape variation. While morphometric analyses did not reveal significant shrinkage in cavity-like structures, geometric morphometric analyses demonstrated significant shrinkage in the third ventricle.

Conclusions

This study is unique in that it is the first to comprehensively demonstrate, using geometric morphometry, the morphological changes that occur in brain tissue during plastination. The findings, when combined with graphical and statistical data analysis, emphasize the effectiveness of geometric morphometry as a powerful tool for elucidating shape changes in plastination research.
背景:塑化可长期保存生物标本,几何形态计量学可通过先进的统计方法分析形状差异。本研究的主要目的是对塑化后大脑切片的收缩情况进行统计量化。次要目标是利用几何形态测量法展示特定解剖结构的组织和腔隙的收缩情况:九个雄性牛脑的十四个切片均采用标准技术进行硅胶塑化,包括四个阶段:固定、脱水、强制浸渍和固化。使用 ImageJ 测量塑化切片的收缩百分比,并使用几何形态测量法进行形状分析。进行相关分析以揭示脑室面积与收缩百分比之间的关系:结果:在每个脑切片中都观察到明显的萎缩。切片收缩率与脑室面积之间呈正相关。然而,除了第 9 个切片外,其余切片的这种相关性在统计学上并不显著。此外,不同切片之间的相关性强度也存在差异。利用几何形态计量学,收缩和序列脑切片中特定解剖区域的相关形状变化以直观图形进行了说明。形状分析显示,冠状沟、喙上沟、丘脑腹面和第三脑室的收缩最为明显。此外,海马角(cornu ammonis)的萎缩和形状变化最为显著。虽然形态计量分析没有发现空腔样结构有明显的萎缩,但几何形态计量分析表明第三脑室有明显的萎缩:这项研究的独特之处在于,它首次利用几何形态计量学全面展示了脑组织在塑化过程中发生的形态变化。研究结果与图形和统计数据分析相结合,强调了几何形态测量法作为阐明塑化研究中形态变化的有力工具的有效性。

This scoping review was conducted based on the Joanna Briggs Institute's theoretical framework and registered with the Open Science Framework (https://osf.io/b27wc). The study analyzed 29 manuscripts published between 2013 and 2023, focusing on imaging exams to synthesize evidence on the anatomy and clinical correlations of the upper urinary tract. The results revealed significant findings, highlighting the intrarenal pelvis as a possible predictive indicator of urinary loss after partial nephrectomy. This emphasizes the importance of anatomical assessment of the renal pelvis. Brödel's avascular plane has been categorized into three types relevant to pre-surgical patient planning. Multiple renal arteries and venous variations have also been reported, including retro-aortic and circum-aortic renal veins. A movable section related to the ureter was described in the perirenal space, delimited by the point of intersection with the gonadal vessels. The ureteropelvic and ureterovesical junctions were found to be anatomical points susceptible to ureteral constriction. On the other hand, the point at which the ureter crosses the iliac vessels is no longer considered a site prone to ureteral obstruction. The authors emphasize the need to adopt a standardized terminology to describe the anatomical variations of the blood vessels related to the kidney. Using diverse and unclear terms can hinder teaching and research in this area and lead to inaccuracies. From the authors' perspective, imaging exams have enhanced anatomical accuracy, benefiting the teaching of human anatomy and significantly contributing to continuous medical breakthroughs.
本范围综述基于乔安娜-布里格斯研究所(Joanna Briggs Institute)的理论框架进行,并在开放科学框架(https://osf.io/b27wc)上进行了注册。研究分析了2013年至2023年间发表的29篇手稿,重点关注成像检查,以综合上尿路解剖和临床相关性方面的证据。结果显示,肾盂内是肾部分切除术后遗尿的可能预测指标。这强调了对肾盂进行解剖评估的重要性。Brödel 的血管平面被分为三种类型,与手术前的患者规划相关。也有报道称存在多种肾动脉和静脉变异,包括主动脉后肾静脉和环主动脉肾静脉。肾周间隙有一个与输尿管有关的可移动部分,以与性腺血管的交汇点为界。发现输尿管骨盆和输尿管静脉交界处是输尿管容易收缩的解剖点。另一方面,输尿管与髂血管的交叉点不再被认为是输尿管阻塞的易发部位。作者强调有必要采用标准化术语来描述与肾脏有关的血管的解剖变化。使用不同且不明确的术语会妨碍该领域的教学和研究,并导致不准确的结果。在作者看来,成像检查提高了解剖学的准确性,有利于人体解剖学的教学,并极大地促进了医学的不断突破。

Background

Inguinal hernia is one of the most common visceral surgical conditions in industrialised countries. The aim of the present observational clinical study was to investigate the dermatome patterns after nerve injury following inguinal hernia surgery and to demonstrate the marked individual anatomical and topographical variability of peripheral nerves in the inguinal region.

Methods

220 patients were followed up for one year after inguinal herniotomy. Surgical treatment was performed either with tension-free mesh techniques or open according (Lichtenstein).

Results

One year after inguinal herniotomy, 25 patients (11.4 %) reported postoperative symptoms. Of these, 15 patients showed evidence of a distinct nerve lesion. The results of the clinical neurological examination sometimes differed considerably from the subjective perceptions of the patients. In addition, a marked individual variability in the dermatomes of surgically lesioned nerves was found, with discrepancies to the classical and conventional dermatome data in textbooks.

Conclusions

This study has shown that it is hardly possible to assign a specific lesional inguinal dermatome to a specific nerve, as nerves show a large individual variability in their anatomical, topographical location and thus in their dermatome boundaries. Therefore, we propose a descriptive approach to the terminology of peripheral inguinal nerve lesions using common regional landmarks. This will avoid a potentially erroneous dermatome assignment to a certain nerve and facilitate the reproducibility of lesion descriptions between different observers, thus facilitating communication in clinical practice.
背景:腹股沟疝是工业化国家最常见的内脏外科疾病之一。本临床观察研究的目的是调查腹股沟疝手术后神经损伤后的皮膜形态,并证明腹股沟区周围神经在解剖学和地形学上存在明显的个体差异。方法:对 220 名腹股沟疝气切除术后一年的患者进行随访,手术治疗采用无张力网技术或开放式(Lichtenstein):结果:腹股沟疝气切除术一年后,25 名患者(11.4%)出现术后症状。其中,15 名患者有明显的神经损伤迹象。临床神经检查的结果有时与患者的主观感觉相差很大。此外,还发现手术病变神经的皮节存在明显的个体差异,与教科书中经典和传统的皮节数据存在差异:本研究表明,很难将特定的腹股沟病变皮节归属于特定的神经,因为神经在解剖学和地形学位置上存在很大的个体差异,因此其皮节边界也存在很大的个体差异。因此,我们建议采用一种描述性的方法,利用常见的区域地标来命名腹股沟周围神经病变。这将避免对某一神经进行可能错误的皮测分配,并提高不同观察者之间病变描述的可重复性,从而促进临床实践中的交流。

Background and objective

There is currently a lack of anatomical research on the C7 pedicle and lateral mass in children aged 0–14 years, and experience with pediatric lower cervical spine surgeries remains limited. This study aims to investigate the anatomical structure of the C7 pedicle and lateral mass in a large pediatric sample to understand their growth patterns, providing imaging and anatomical references for pediatric lower cervical spine surgeries and the design of pediatric C7 screws.

Methods

We measured 12 parameters, including the width, length, height, and angles of the C7 pedicle and lateral mass in children aged 0–14 years. The t-test was used to analyze bilateral and gender differences, and least squares regression was applied for curve fitting analysis.

Results

The size parameters of the C7 pedicle and lateral mass generally increased with age, while angular parameters fluctuated within specific ranges. The average values for each parameter between ages 0–14 were as follows: D1: 2.78–5.28 mm, D2: 18.15–30.54 mm, D3: 2.44–6.01 mm, angle A: 38.05–44.48°; D4: 6.81–10.94 mm, D5: 5.37–11.23 mm, D6: 8.07–13.28 mm, D7: 1.94–4.88 mm, D8: 5.67–9.39 mm, angle C: 18.50–28.80°, angle D: 43.23–52.01°, angle E: 33.74–44.96°. Bilateral analysis showed no significant differences for most parameters across most age groups, with differences mainly observed in angle A, angle C, D6, and D8. Gender differences were primarily noted in length parameters across different age groups, especially in the 3–4, 6–7, 9–11, and 13–14 age groups. Regression analysis indicated that most parameters followed cubic function curves, while a few followed power or quadratic function curves.

Conclusion

This study provides detailed CT imaging anatomy of the C7 pedicle and lateral mass in children aged 0–14 years. Preoperative thin-slice CT scans and careful measurements of key parameters are essential for pediatric lower cervical spine surgeries. The findings offer valuable imaging and anatomical references for pediatric posterior cervical fixation surgery and screw design.
背景和目的:目前缺乏对0至14岁儿童C7椎弓根和侧块解剖结构的研究,小儿下颈椎手术经验仍然有限。本研究旨在调查大量儿科样本中C7椎弓根和侧块的解剖结构,了解其生长模式,为儿科下颈椎手术和儿科C7螺钉的设计提供影像学和解剖学参考:我们测量了0至14岁儿童C7椎弓根和侧块的宽度、长度、高度和角度等12个参数。采用t检验分析双侧和性别差异,并应用最小二乘法回归进行曲线拟合分析:结果:C7椎弓根和侧块的尺寸参数一般随年龄增长而增加,而角度参数则在特定范围内波动。0-14 岁期间各参数的平均值如下:D1:2.78-5.28mm,D2:18.15-30.54mm,D3:2.44-6.01mm,角度 A:38.05-44.48°:38.05-44.48°;D4:6.81-10.94mm,D5:5.37-11.23mm,D6:8.07-13.28mm,D7:1.94-4.88mm,D8:5.67-9.39mm,C 角:18.50-28.80°,D 角:43.23-52.01°,E 角:33.74-44.96°。双侧分析表明,大多数年龄组的大多数参数无明显差异,差异主要体现在 A 角、C 角、D6 和 D8。不同年龄组的性别差异主要体现在长度参数上,尤其是 3-4、6-7、9-11 和 13-14 年龄组。回归分析表明,大多数参数遵循三次函数曲线,少数遵循幂函数或二次函数曲线:本研究提供了0至14岁儿童C7椎弓根和侧肿块的详细CT成像解剖结构。术前薄层 CT 扫描和关键参数的仔细测量对小儿下颈椎手术至关重要。研究结果为小儿颈椎后路固定手术和螺钉设计提供了有价值的成像和解剖学参考。

Background

Evolutionary changes in human rib cage morphology rendered it prone to pathologies like Scheuermann's kyphosis (SK). However, the impact of SK on rib cage morphology is unclear.

Purpose

This study aimed to examine differences in rib cage morphology (e.g., ribs and sternum) between SK patients and a control group.

Methods

Measurements of the vertebral body, transverse process angle, sternum, and rib size were taken from the skeletons of SK patients (76) and a control group (96). Statistical tests were carried out to examine differences between the study and control groups and between the right and left sides. Correlations were obtained to examine the associations between the extent of the kyphosis (kyphosis angle) and rib cage variables.

Results

The SK group yielded significantly longer and flatter ribs than the control group in both sexes. However, males had the largest differences in the 9th rib and females in the upper ribs (5−7). Inconsistency in symmetry results was found between the sexes. In summary, SK patients had a larger anteroposterior diameter in relation to the transverse diameter than the control group.

Discussion and Conclusions

SK affects the morphology of the entire thorax and changes rib proportions similarly in males and females. These changes might have a role in bipedal stability and locomotion efficiency. Moreover, understanding the unique anatomy of SK patients is essential when performing an anterior release and anterior fusion operative approach. Finally, it provides insights into respiratory complications and poor prognosis related to individuals suffering from severe hyperkyphosis.
背景:人类肋骨笼形态的进化变化使其容易发生病变,如舍尔曼氏脊柱侧弯症(SK)。目的:本研究旨在探讨SK患者与对照组之间在肋骨笼形态(如肋骨和胸骨)方面的差异:从 SK 患者(76 例)和对照组(96 例)的骨骼中测量椎体、横突角、胸骨和肋骨的尺寸。对研究组和对照组之间以及左右两侧之间的差异进行了统计检验。对脊柱后凸的程度(后凸角度)和肋骨笼变量之间的相关性进行了检验:结果:SK 组的肋骨明显比对照组的肋骨更长、更平,男女均是如此。然而,男性第 9 肋骨和女性上肋骨的差异最大(5-7)。性别间的对称性结果不一致。总之,与对照组相比,SK 患者的前胸直径相对于横径较大:讨论和结论:SK 会影响整个胸廓的形态,并同样改变男性和女性的肋骨比例。这些变化可能会影响两足的稳定性和运动效率。此外,在采用前路松解和前路融合手术方法时,了解 SK 患者的独特解剖结构至关重要。最后,它还为患有严重脊柱后凸的患者的呼吸系统并发症和不良预后提供了见解。
