“…To ensure the safe and effective completion of surgical procedures, a thorough understanding of surgical anatomy is essential. This is particularly crucial when novel surgical methods or tools that test the surgeon's knowledge of relevant anatomical features are developed (7).…”

Background: The trans-obturator tape (TOT) procedure is an efficient treatment option that provides support for the urethra in cases of stress urinary incontinence (SUI). Objectives: This research aimed to ascertain the accuracy of anthropometric parameters of the female pubic arch and the obturator foramen (OF) and their application in clinical anatomy. Methods: In this cross-sectional observational research conducted from October 2021 to September 2022, the morphometric characteristics of the pubic arch and the OF were measured on digital pelvic radiographs of 500 adult women from southwestern Iran. They were grouped into three age categories, namely, 18 - 34, 35 - 50, and more than 50 years old, and compared within and between the groups. Results: Significant differences were observed in computed parameter indices of the OF and pubic arch based on age. Parameters such as inter-obturator foramina distance, pubic symphysis length, pubic ramus width, and length increased significantly with age (P ≤ 0.05). Additionally, as women's ages increased, their subpubic angle decreased significantly (P = 0.001). However, other parameters, such as the OF area and the anterior urogenital triangle area, did not show a significant increase with age (P ≥ 0.05). These findings indicate that anatomical pelvic measurements change significantly with age in women. Conclusions: The present study revealed a wide range of variant bony pelvic anatomy in southwestern Iranian adult women, distinct from norms in other groups. Our findings could be utilized in surgical approaches and the production of trans-obturator kits by companies.

Background Learning and applying anatomy are essential but are studied and done through 2D tools and imaging techniques. This study aims to verify the usefulness of an additional 3D technique and ensure an improvement in the visualization of anatomical structures and pathological findings. Objective The study aims to examine the usefulness of virtual reality (VR) technology as an additional tool in medical diagnostics. Groups of students, residents, and specialists in surgery, radiology, and internal medicine evaluated magnetic resonance imaging (MRI) by answering a multiple-choice questionnaire. Subsequently, a virtual 3D display was used for processing. The questionnaire focused on topographical conditions and the transfer of academic knowledge into clinical application. The main objective was to determine anatomical understanding in a comparison between sectional image (2D) presentation and additional VR (3D) presentation, measured through correctly answered questions and processing time. The system usability scale (SUS) was integrated as another criterion for VR usability. Methods The cross-over study assessed 63 participants regarding their knowledge of liver anatomy and pathologies based on an interindividual comparison. Group formation according to the respective level of medical training was as follows: students (n=35), residents (n=15), and specialists (n=13). Participants answered 25 multiple-choice questions first using sectional imaging (MRI) in a 2D environment (computer screen) and afterward with the respective segmented 3D model visualized in a VR simulation. The main criteria for the analyses were the number of correctly answered questions and processing time. A customized SUS was used to analyze VR usability. Missing data analysis showed that there were no accounted missing data. Results The rate of correct answers improved significantly with the additional use of VR (F1,59=314.376; P<.001). Using MRI, a significant difference was observed between students and residents (P=.04) and between students and specialists (P<.001). In the VR condition, no significant differences between groups were found. In the MRI condition, significant differences in processing time were observed between students and specialists (P=.02) and between residents and specialists (P=.04). No differences existed between students and residents. With VR, processing time decreased significantly in all groups (F1,59=280.700; P<.001). Significant differences between students and specialists (P=.02) and between students and residents (P=.004) remained. No notable differences between residents and specialists (P=.72) were found. The SUS showed a subjectively simplified answerability of the questions with additional use of VR. The usefulness and benefits for an additional use of VR were stated. Conclusions The additional use of VR suggests statistically significant improvements across all groups. VR seems to enable students and residents to participate in diagnostics and create treatment plans at an early stage. Transferred to clinical practice, this may lead to improvement in diagnostics and interventions. The lack of randomization and a potential learning effect are the main limitations to be addressed in future studies.

BACKGROUND Learning and application of anatomy is essential but is studied and used in hospitals mostly through two-dimensional tools and imaging techniques. Therefore, the objective of this study is to verify the usefulness of an additional 3D technique and ensure a significant improvement in the visualization of anatomical structures and pathological findings. OBJECTIVE Examine the usefulness of virtual reality technology (VR) as an additional tool in medical diagnostics. Groups of students, residents and specialist in general and visceral surgery, radiology and internal medicine had to evaluate MRI (Magnetic resonance imaging) images by answering a multiple-choice (MC) based questionnaire. Subsequently, a virtual 3D display was used for processing. The questionnaire focused on the topographical conditions and the transfer of academic knowledge into clinical application. The main objectives were to determine the anatomical understanding in comparison between a 2D presentation and an additional VR (3D) presentation, measured by the error rate and response time based on the MC questions. The system usability scale was integrated as another criterion for usability of VR. METHODS 63 participants (students, residents, specialists) were assessed with regards to their knowledge on patient-specific liver anatomy and pathologies based on an interindividual comparison. Participants answered 25 multiple-choice questions first using 2D imaging (MRI) and afterwards with the respective segmented 3D model of the liver converted from MRI-data and visualized in a VR-simulation. Main criteria were “error rate” and “processing time”. RESULTS The error rate improved significantly by the additional use of VR (p=0.001). Using MRI, a significant difference between students and residents (p=0.042), as well as between students and specialists (p= <0.001) was shown. In the VR condition no significant differences between groups were found. In MRI condition significant differences in processing time between students and specialists (p=0.02) and between residents and specialists (p=0.047) were shown. No differences existed between students and residents. With VR the processing time decreased significantly in all groups (p=0.001). Significant differences between students and specialists (p=0.02) and between students and residents (p=0.004) remained, but there were no notable differences between residents and specialists (p=0.72). CONCLUSIONS The additional use of VR showed in all groups a significant improvement regarding error rate and general processing time. Transferred to clinical practice, this may lead to improvement in diagnostics and interventions. Using VR enables students and residents to participate in diagnostics and to create treatment plans at a very early stage. CLINICALTRIAL Our study, although randomized, could not be officially registered as a clinical trial due to its non-clinical nature. We submitted the study to the medical ethics committee of the Carl von Ossietzky University, which approved the study. Ethics approval statement: The medical ethics committee of Carl von Ossietzky University accepted this study (application number 2021-162). The study was registered with the German Register of Clinical Studies (DRKS). Informed consent statement: All participants gave their written informed consent.
