Outcome Analysis of Distal Radius Fracture with Orthosis Versus Cast Immobilization after Palmar Plate Osteosynthesis: A Randomized Controlled Study.

Although the benefits of hand orthoses were shown in previous studies, they have not been able to establish themselves in clinical routines. With a focus on patient satisfaction, this study aimed to evaluate the latest generation of hand orthoses after palmar plate osteosynthesis for isolated distal radius fractures in comparison with circular plaster casts. 50 patients (16% dropout rate) were randomly assigned to an orthotic group (immobilization by orthosis, OG) or a control group (immobilization by a plaster cast, CG). Intra-articular fractures were present in 74% of the cases, and unstable AO C3 fractures in 26%. Questionnaires on patient satisfaction, documentation of the time required, clinical scores (DASH, SF-36), range of motion, grip measurements and radiographs were used for evaluation. The OG proved to be equivalent to the plaster treatment in terms of patient satisfaction, and stability of the reduction, as well as clinical scores DASH and SF-36. The OG was even superior in terms of personal hygiene (p = 0.011), handling (p = 0.008) and better adaptability (p = 0.013). Significantly less time was required to apply the orthosis (p < 0.001). In addition to the good results achieved so far, the study showed that the latest generation of orthoses has several advantages over plaster cast therapy, and could therefore become established in everyday clinical practice.

Medical education videos as a tool for rehearsal: efficiency and the cases of background music and difficulty.

This study reports a field experiment investigating how instructional videos with and without background music contribute to the learning of examination techniques within a formal curriculum of medical teaching. Following a classroom teaching unit on the techniques for examining the knee and the shoulder joint, our participants (N = 175) rehearsed the studied techniques for either the knee or the shoulder joint with an instructional video with or without background music. As dependent measures, we collected a general questionnaire, a prediction of test performance, as well as performance on an exam-like knowledge test covering both joints. For both videos, the participants who had watched the particular video during rehearsal were more accurate in answering the corresponding questions than the participants who had seen the other video, signaling that instructional videos provide a useful tool for rehearsal (i.e., both groups reciprocally served as control groups). For the knee video (less difficult), we observed a detrimental effect of the background music, whereas we observed no such effect for the shoulder video (more difficult). Further explorations revealed that background music might be detrimental for learning, as it reduces the perceived demand characteristics. Because the impact of the demand characteristics might be more pronounced in less difficult instructional videos, we discuss video difficulty as a potential moderating factor. Overall, our study provides evidence that instructional videos could be usefully implemented in formal teaching curricula and that such instructional videos probably should be designed without background music.

Evidence-Based Examination Techniques for the Shoulder Joint. / Evidenzbasiertes Lehrvideo für Untersuchungstechniken am Schultergelenk.

OBJECTIVE: Digitalisation now almost covers all areas of medical student teaching. Teaching videos are a good way to help students learn practical skills. The existing evidence is a recognised aid for the classification of the respective technology. METHOD: This video presents the usual examination techniques of the shoulder joint on a patient with an unstable shoulder. The respective techniques, if available, were backed up with appropriate evidence. CONCLUSION: The examination techniques presented allow students to view them in a standardized manner on a patient. The evidence for the examination techniques can help with the classification of the respective technique.

Mentored undergraduate operating room teaching during the orthopedic trauma curriculum-No evidence of gender differences.

BACKGROUND: In many surgical disciplines, the interest among medical students to pursue a surgical career decreases during their medical studies. The same goes for students after graduation. The aim of our cohort study was to evaluate the operating room (OR) experiences of medical students during our curriculum. MATERIALS AND METHODS: Over the course of one year 217 senior year medical students were included in our study. All of them took part in our training program for senior year medical students, which consisted of a 1-week clinical rotation including visits to the OR. We developed a Likert-scaled questionnaire, which was evaluated anonymously; free text answers were also possible. RESULTS: Prior to the analysis of the sex and age differences, we confirmed that the evaluation scale provided a coherent measure of the OR evaluation. As a first proxy, we conducted a series of Spearman correlations which revealed high intercorrelations between all of the six items of the questionnaire, r(154) = 0.53 to r(154) = 0.94, all p < 0.001. These high intercorrelations transferred into a very high consistency of the six questions that evaluate the OR teaching; Cronbach's α = 0.95. There was no main effect of sex, F (1,146) = 2.19, p = 0.141. However, there was a main effect of age, F (2,146) = 3.75, p = 0.026, indicating that older participants evaluated the OR teaching more positively. Finally, there was no correlation between sex and age group, F (2,146) < 1, indicating that the effect of age on the evaluation score was equally pronounced for female and male participants. DISCUSSION: The aim of this study was to answer the question how mentored OR teaching during the orthopedic trauma curriculum is evaluated by medical students, and whether there are gender-specific differences. For this purpose we prospectively evaluated senior year medical students over a period of 12 months during the orthopedic trauma curriculum with questionnaires. The medical students rated the mentored OR visits mainly positive. CONCLUSION: Previously published literature as well as our presented data indicate that the interest of medical students in starting a surgical career can only be increased if negative influencing factors are reduced. This includes especially positive communication with medical students and in daily professional interaction.

Checklist Focused on Patients for Making of Teaching Videos in Orthopedic Surgery. / Patientenorientierte Checkliste für die Erstellung von Lehrvideos für Orthopädie und Unfallchirurgie.

INTRODUCTION: The focus of medical-didactic research is the improvement of clinical-practical training. One way to support practical skills training in a time- and resource-saving way is to provide instructional videos. Often the freely available instructional videos do not meet didactic or content requirements. Creating your own videos can therefore be a useful alternative for teachers. There are a variety of instructions on the Internet for shooting instruction videos. To date, this does not include any concrete instructions/assistance for the production of medical instructional videos. However, the presentation of medical learning content in particular can contain many hurdles. The aim of this work was to design a checklist for the creation of instructional videos, which can be used as a guide. METHODS: As a first step, a systematic literature search was carried out to identify works that deal with the creation and not the use of medical instructional videos. To date, corresponding publications do not exist. In a workshop, the participants, who already gained experience in creating this type of video, exchanged ideas. These were critically discussed and analyzed. As a result, a checklist was created. In a subsequent multi-step review process, the checklist was reviewed with regard to applicability, comprehensibility, completeness and quality of the items. RESULTS: Four phases in the creation of an instructional video could be differentiated: preliminary reflections, preparation, day of filming, post-production. The checklist is structured accordingly and should be actively processed phase by phase. The checklist is created in such a way that it can be used and edited without reading this text. Particular focus is placed on the patient and his needs. CONCLUSION: The checklist created provides useful help in the creation of medical instructional videos and can for the first time serve as a guide especially for orthopedic and accident surgical instructional videos.

Surgeons' participation in the development of collaboration and management competencies in undergraduate medical education.

The teaching of professional roles in medical education is an interdisciplinary concern. However, surgeons require specific standards of professionalism for certain context-based situations. In addition to communication, studies require collaboration, leadership, error-/conflict-management, patient-safety and decision-making as essential competencies for surgeons. Standards for corresponding competencies are defined in special chapters of the German National Competency-based Learning Objectives for Undergraduate Medical Education (NKLM; chapter 8, 10). The current study asks whether these chapters are adequately taught in surgical curricula. Eight German faculties contributed to analysing mapping data considering surgical courses of undergraduate programs. All faculties used the MERlin mapping platform and agreed on procedures for data collection and processing. Sub-competency and objective coverage, as well as the achievement of the competency level were mapped. Overall counts of explicit citations were used for analysis. Collaboration within the medical team is a strongly represented topic. In contrast, interprofessional cooperation, particularly in healthcare sector issues is less represented. Patient safety and dealing with errors and complications is most emphasized for the Manager/Leader, while time management, career planning and leadership are not addressed. Overall, the involvement of surgery in teaching the competencies of the Collaborator and Manager/Leader is currently low. However, there are indications of a curricular development towards explicit teaching of these roles in surgery. Moreover, implicitly taught roles are numerous, which indicates a beginning awareness of professional roles.

[Who benefits from medical technical innovations? : A medical and medical economic analysis using the example of lumbar disc surgery]. / Wer profitiert von medizinisch-technischen Innovationen? : Eine medizinische und medizinökonomische Betrachtung am Beispiel lumbaler Bandscheibenoperationen.

Further developments in disease diagnosis and treatment are of immense relevance for advancements in medical care of the population. A detailed cost-benefit analysis of direct and indirect costs is usually unavailable. In the current article, these aspects are investigated using prospectively collected randomized data over two years. Specifically, the surgical treatment of a herniated lumbar disc is addressed, and whether a newly introduced technique (e.g., annular closure device) can lead to a better quality of care and increased patient satisfaction when performed during the standard operation, while also being economically viable.

[Position Paper of the Surgical Working Group for Teaching of the German Society of Surgery Regarding the "Master Plan 2020"]. / Positionspapier der chirurgischen Arbeitsgemeinschaft Lehre für die Deutsche Gesellschaft für Chirurgie zum "Masterplan Medizinstudium 2020".

The "Masterplan Medizinstudium 2020" from the German Federal Government should not be underestimated as only one among many announcement. Thus, the Surgical Working Group on Medical Education (CAL) of the German Association of Surgeons (DGCH) comments on the intended measures of the "Masterplan Medizinstudium 2020" and discusses the challenges, consequences and duties arising from the "Masterplan Medizinstudium 2020" for the representatives of the surgical societies and those engaged in surgical undergraduate training.

[Mandatory Surgical Subinternship in the Final Year of Medical School - a Stepping Stone to Becoming a Surgeon?] / Chirurgisches Pflichttertial im Praktischen Jahr ­ das Sprungbrett in die chirurgische Weiterbildung?

BACKGROUND: The final year is an important time for a medical student as this is when medical knowledge is transformed into medical responsibilities. The field of surgery is firmly anchored in the educational structure as it is mandatory during the practical year of a medical student. The purpose of this paper is to identify factors that influence medical students to choose surgery after the final year of medical school. MATERIALS AND METHODS: An online survey conducted by the AG DGOU 2012 provided complete data sets from a total of 9079 participants. 184 of these had already completed their PJ compulsory sub-internship (tertiary) surgery. These were divided into four groups for analysis: decision to specialise in surgery prior to the PJ compulsory tertiary ("yes, before", JV), during the PJ compulsory ("yes, during", JW), decision against before the PJ compulsory ("no, before", NV) or during the compulsory ("no, during", NW). The total of 38 survey items were summarised for overall assessment, taking into account the decision on subject specialisation. RESULTS: 57.9% of the respondents were positive regarding the overall impression of the surgical internship during their final year. The respondents of the JW group were especially positive, having made the decision to become a surgeon, based on their internship experience during the final year in comparison to the NW group (decision against surgery). We find significant differences in all analysed items: integration into team JW/NW (p ≤ 0.003), acquisition of expertise (p ≤ 0.014), teachers (p ≤ 0.025), quality and structure of teaching (p ≤ 0.043) and overall satisfaction with the required tertial (p ≤ 0.037). CONCLUSION: In comparison to other specialities, in the field of surgery there is the option of recruiting directly within the framework of the compulsory internship. The results reveal unsatisfactory structures from a student perspective. The lack of medical care/support, the insufficient inclusion in therapeutic considerations, the lack of professional knowledge and lack of contact with the teachers are just a few key points that negatively impact the overall outcome of students' satisfaction with the compulsory tertiary education. The results of the present study should serve as motivation and contribute to the restructuring of the compulsory core of the Practical Year, which the Master Plan 2020 will entail.

[Quality and Satisfaction with the Surgical Medical Clerkship from a Student Perspective]. / Qualität und Zufriedenheit mit der chirurgischen Famulatur aus studentischer Sicht.

PREFACE: The surgical medical clerkship is of special importance, as the student is given the opportunity to get in touch with medical colleagues and patients for the first time, and the interest in a certain field of specialisation can be consolidated. The present study will clarify how students perceived their medical clerkship in the field of surgery. METHODS: A nationwide online survey carried out in 2012 was able to recruit 9079 participants, and contained questions about the completed curricular internships. The present evaluation contains the data of those respondents who had completed at least four weeks of internship in surgery. The following main groups were of particular interest: overall assessment, satisfaction, structure and quality of teaching, of the teachers, and the acquisition of practical skills, which were divided into 35 items. Statistical evaluation was carried out using SPSS 22.0 (IBM Corp., Armonk, USA). In addition to the descriptive statistics, the Chi² test was performed for frequencies, and univariate ANOVAs with the sub-subject factor group (satisfied, neutral, dissatisfied) were performed for the individual items. RESULTS: Overall, the data of 526 participants could be analysed. The female proportion of students was 56.7%; the average age at the time of the survey was 25 years. In all evaluated items, there were significant differences between the groups satisfied and dissatisfied. The participants of the survey who were satisfied with the overall qualification (p = 0.000), reported that they benefited with regard to the technical and didactic quality of teaching (p = 0.000), the acquisition of practical competences (p = 0.000), as well as the didactic and professional quality of teaching (p = 0.000). DISCUSSION: Little is published about the internships for students, including the medical clerkship "Famulatur". However, this information seems to be important, as the students can freely choose the subject in which the Famulatur can be completed. Thus, in this early phase of training, it is possible to recruit young academics for the department by optimising existing structures and improving the range of courses.

[Weighting of Orthopaedics & Trauma Surgery in the Medical State Examination - Comparison of the Written Examination with the National Catalogue of Learning Objectives in Surgery]. / Die Wertigkeit des gemeinsamen Faches Orthopädie-Unfallchirurgie im 2. Staatsexamen ­ Vergleich der schriftlichen 2. Staatsexamina mit dem Nationalen Kompetenzbasierten Lernzielkatalog Chirurgie.

BACKGROUND: The national competence-based catalogue of learning-goals in surgery (NKLC) defines competence levels for each of its 230 goals, including "competence level in 1: factual knowledge" up to "competence level 3: independent action". Aside from the cumulative examinations influencing the learning behaviour of students, those teaching targets do not affect the second state examination. This study analyses the extent to which the questions of the German second medical licensing examination compiled by the IMPP (central German institute for medical and pharmaceutical examinations) are congruent with the trauma-surgical and orthopaedic learning goals in the NKLC, in which this thematic focus is emphasised. MATERIAL AND METHODS: Exam questions from autumn 2009 to autumn 2014 (n = 11) were retrospectively analysed. Orthopaedic and trauma-surgical teaching targets defined in NKLC were identified by five senior orthopaedic physicians and trauma surgery experts. All questions addressing one of these learning goals were identified and analysed (re: the number of learning goals, the number of questions addressing a trauma-surgical, or orthopaedic goal, as well as different competency levels). RESULTS: We found 113 learning goals of NKLC (49.1% of the overall NKLC learning goals) identified as orthopaedic or trauma surgery subjects. During the study period, 543 questions included teaching targets referring to orthopaedic or trauma surgery subjects (15.6% of the total of 3480 questions). Per exam, a mean of 49.36 ± 14.1 questions (minimum 30; maximum 80) was identified that addressed a learning goal referring to these issues. For each exam, 13.45 ± 6.39 (minimum 6; maximum 24) questions referred to learning goals of competence level 3a and b, 21.45 ± 9.94 (minimum 9; maximum 39) questions referred to learning goals of competence level 2, and 14.45 ± 6.36 (minimum 6; maximum 25) questions referred to learning goals of competence level 1. Most questions addressed the topic: "disorders of the rheumatic spectrum" (n = 16 questions in autumn 2009). CONCLUSION: Questions focusing on orthopaedic and trauma surgery appeared sufficiently often during the second state examination. There is a thematic imbalance, and important clinical learning goals tagged with high competence levels were not addressed in a satisfactory manner. This indicates that a clear adjustment between the state examination and NKLC is necessary.

The surgical experience of current non-surgeons gained at medical school: a survey analysis with implications for teaching today's students.

BACKGROUND: It is unknown what aspects of undergraduate surgical curricula are useful for future non-surgeons. We aimed to define relevant, enduring learning achievements for this subgroup to enable student-centered teaching. METHODS: An online questionnaire using open ended questions was distributed to physicians of non-surgical specialties at the University Hospital of Tuebingen, Germany and its associated teaching hospitals. Participants were asked to describe knowledge and skills that endured from their surgical clerkship and which of these are used in daily practice. Textual responses were initially coded using content analysis and the frequency of recurrent categories was calculated. RESULTS: Sixty-seven of 153 questionnaires were returned; participants belonged to six different non-surgical specialties and had received their training at 22 different medical schools. Sustaining learning achievements included basic skills (suturing and working under sterile conditions), learning about professionalism and appreciating working conditions in surgery. Two learning techniques were valued: witnessing of rare cases or complications and working autonomously. CONCLUSION: Integration of our findings in undergraduate surgical teaching may focus teaching on students' interests and improve surgical teaching.
