RESUMO
BACKGROUND: Due to the global digitalization, implementation of digital elements into daily work can support physiotherapists' work but may also pose some challenges. Only little is known about physiotherapists' attitude towards digitalization. This study primarily aimed to analyze physiotherapists' attitude towards digitalization and to what extend digital tools have been implemented into their daily work. In second analysis, participants' characteristics such as age, working place, gender and mode of survey participation were assessed. METHODS: A 12-main-item survey amongst voluntary course participants of one physiotherapeutic training center was conducted via paper-based as well as online questionnaires between July 2018 and June 2019 including questions on participants' general as well as particular attitude towards digitalization, the use of (mobile) applications and possible advantages and disadvantages of the ongoing digital transformation. Sub-analysis was performed for age (≤40 years versus > 40 years), gender, mode of participation (paper vs. online) and working place (practice vs. hospital). RESULTS: Overall, 488 physiotherapists participated in the survey. In comparison of the age groups, younger participants had more concerns about data security (p = 0.042) and insufficient financial remuneration (p < 0.001). Younger participants stated higher satisfaction with data literacy than their counterparts (p = 0.0001). Physiotherapists working in the outpatient sector, rather than in hospitals, expected digitalization to increase more in relevance (p < 0.001). The online respondents (OG) indicated that they had more knowledge about key aspects of the current legal situation regarding digitalization than participants completing the paper-based survey (p = 0.002). 50.4% of the considered digitalization as useful for their job. CONCLUSIONS: The majority of participants saw high potential for digitalization in the physiotherapy sector. Younger physiotherapists seem to be more concerned about data security and insufficient financial remuneration. Physiotherapists in the outpatient sector seem to see more potential in digital transformations. General concerns like missing reimbursement, lack of data security or knowledge on legal frameworks should be addressed in the future. Further studies should focus on identifying specific digital tools which can support physiotherapists.

INTRODUCTION: In addition to the advantages for patients and physicians, the progression of digitalization will also have economic implications for healthcare systems in toto worldwide. The integration of digital innovations enables healthcare institutions to transform their current activities and processes and to create a new form of patient care. IMPORTANT ECONOMIC TOPICS OF DIGITALIZATION: Using digital applications process optimization can be achieved by increased efficiency and therefore a reduction in costs in the healthcare system. Improved processes can in turn achieve an increase in quality in the treatment of patients. Simultaneously, a duplication of investigations can be avoided through digital interfaces and the communication among the healthcare professions involved can be improved, which would result in a conservation of resources. Finally, these influences can lead to more precision in medicine, acceleration of healing processes and represent an advantage for all parties involved. PERSPECTIVES: Economic redistribution due to digitalization of medicine will become increasingly apparent in the future. Ethical considerations as well as data protection will be important topics. At the same time investments and digital innovations must be sponsored by the government and industry. Scientific studies are necessary to secure the evidence of new methods for practice in orthopedics and trauma surgery.

BACKGROUND: In the management of trauma patients in the resuscitation room many time-pressured and critical decisions must continuously be made in complex situations. Even experienced teams frequently make errors in this context. Computer-assisted decision-making systems can predict critical situations based on patient data continuously acquired online. Based on the calculated predictions these systems can suggest the next steps in managing the patient. This review summarizes the current literature on computer-assisted decision-making in the management of trauma patients. OBJECTIVE: A literature review summarizing existing concepts and applications of computer-assisted decision-making support for the management of trauma patients. METHODS: Narrative review article based on an analysis of literature in the German and English languages from the last 10 years. RESULTS: There exist numerous computer-assisted decision-making systems in the field of trauma care. Several studies could show that computer-assisted decision-making can improve the outcome in the preclinical setting, the resuscitation room and in the intensive care unit. For further validation and implementation of these systems, information technological barriers have to be overcome, existing systems need to be adapted to current data protection regulations and large multicenter studies are necessary. CONCLUSION: Computer-assisted decision-making can help to improve the management of trauma patients; however, before a ubiquitous implementation a number of technological and legislative barriers have to be overcome.

INTRODUCTION: In its digital agenda the German Federal Government pursues the ambitious objective to facilitate digital competence and perform research into digital learning and teaching processes. Considerable investments are to be concentrated into the future viability of education, academic research and digitalization. As far as academic teaching and further education are concerned, not only in the field of orthopedics and trauma surgery, three aspects can be identified: digital organization, digital competence and digital tools. DIGITAL APPLICATIONS: New formats, such as the elective subject digital health of the Charité in Berlin, enable digital competences to be mediated in a multimodal and interdisciplinary way. With the help of a newly developed app the University of Essen provides teachers and students with mobile and flexible access to information on lectures in terms of content and organization. Especially because of transparency, high legal compliance and predictability, the digital logbook for the resident training program promises a real innovation for trainees in the further training reformation. Augmented and virtual reality play a crucial role in the imparting of practical skills and interconnect high-tech with classical craftsmanship. Digital training course formats have significantly gained in importance and are meanwhile well-established tools for efficient advanced medical training. OUTLOOK: If orthopedic and trauma surgeons take an active role in the process of digitalization of teaching, they can take part in decisions, adequately prepare the colleagues of tomorrow, optimize patient care, encourage innovations and altogether improve the discipline even more.

INTRODUCTION: Military surgeons must be prepared to care for severe and complex life-threatening injuries rarely seen in the civilian setting. Typical civilian training and practice do not provide adequate exposure to the broad set of surgical skills required. The German Bundeswehr Medical Service has developed and refined the War Surgery Course (WSC) to meet this training gap. This article describes the recent experience with this readiness curriculum. METHODS: Run annually since 1998, WSC consists nowadays of 5â days with 20 theoretical modules. Four sessions with standardised practical skills training use a live tissue porcine model, and the recently added cadaver-based Advanced Surgical Skills for Exposure in Trauma course. Sixteen military surgeons who participated in the WSC in January 2016 completed a survey of their self-rated readiness for 114 predefined emergency skills before and after completion, and provided an overall evaluation of the course. RESULTS: Self-assessed readiness improved significantly over baseline for all areas covered in both the practical skills and theoretical knowledge portions of the WSC curriculum. Additionally, all participants rated the course as important and universally recommended it to other military surgeons preparing for missions. CONCLUSIONS: The WSC course format was well received and perceived by learners as a valuable readiness platform. Ongoing evaluation of this course will enable data-driven evolution to ensure a maximum learning benefit for participants. With the increasing multinational nature of modern military missions, surgeons' training should follow international standards. Continuing evolution of military surgical training courses should further encourage the sharing and adoption of best educational practices.

BACKGROUND: While e-learning is enjoying increasing popularity as adjunct in modern teaching, studies on this topic should shift from mere evaluation of students' satisfaction towards assessing its benefits on enhancement of knowledge and skills. This pilot study aimed to detect the teaching effects of a blended learning program on students of orthopedics and traumatology in the context of a problem-based learning environment. METHODS: The project NESTOR (network for students in traumatology and orthopedics) was offered to students in a problem-based learning course. Participants completed written tests before and directly after the course, followed by a final written test and an objective structured clinical examination (OSCE) as well as an evaluation questionnaire at the end of the semester. Results were compared within the group of NESTOR users and non-users and between these two groups. RESULTS: Participants (n = 53) rated their experiences very positively. An enhancement in knowledge was found directly after the course and at the final written test for both groups (p < 0.001). NESTOR users scored higher than non-users in the post-tests, while the OSCE revealed no differences between the groups. CONCLUSIONS: This pilot study showed a positive effect of the blended learning approach on knowledge enhancement and satisfaction of participating students. However, it will be an aim for the future to further explore the chances of this approach and internet-based technologies for possibilities to improve also practical examination skills.

Infections of contaminated or colonised acute or chronic wounds remain a grave risk for patients even today. Despite modern surgical debridement concepts and antibiotics, a great need exists for new therapies in wound management. Since the late 1990s, advantageous effects of negative pressure wound therapy (NPWT) have been combined with local antiseptic wound cleansing in the development of NPWT with instillation (NPWTi). This article summarises the current scientific knowledge on this topic. MEDLINE literature searches were performed on the subject of negative pressure wound and instillation therapy covering publications from the years 1990 to 2013 (36 peer-reviewed citations) and regarding randomised controlled trials (RCTs) covering wound care with bone involvement (27 publications) or soft-tissue wounds without bone participation (11 publications) from 2005 to 2012. The use of NPWTi in the therapy of infected wounds appears to be not yet widespread, and literature is poor and inhomogeneous. However, some reports indicate an outstanding benefit of NPWTi for patients, using antiseptics such as polyhexanide (concentration 0·005-0·04%) and acetic acid (concentration 0·25-1%) in acute and chronic infected wounds and povidone-iodine (10% solution) as prophylaxis in contaminated wounds with potential viral infection. Soaking times are recommended to be 20 minutes each, using cycle frequencies of four to eight cycles per day. Additionally, the prophylactic use of NPWTi with these substances can be recommended in contaminated wounds that cannot be closed primarily with surgical means. Although first recommendations may be given currently, there is a great need for RCTs and multicentre studies to define evidence-based guidelines for an easier approach to reach the decision on how to use NPWTi.

Advances in technology and digital tools like the Internet of Things (IoT), artificial intelligence (AI), and sensors are shaping the field of orthopaedic surgery on all levels, from patient care to research and facilitation of logistic processes. Especially the COVID-19 pandemic, with the associated contact restrictions was an accelerator for the development and introduction of telemedical applications and digital alternatives to classical in-person patient care. Digital applications already used in orthopaedic surgery include telemedical support, online video consultations, monitoring of patients using wearables, smart devices, surgical navigation, robotic-assisted surgery, and applications of artificial intelligence in forms of medical image processing, three-dimensional (3D)-modelling, and simulations. In addition to that immersive technologies like virtual, augmented, and mixed reality are increasingly used in training but also rehabilitative and surgical settings. Digital advances can therefore increase the accessibility, efficiency and capabilities of orthopaedic services and facilitate more data-driven, personalized patient care, strengthening the self-responsibility of patients and supporting interdisciplinary healthcare providers to offer for the optimal care for their patients.
RESUMO
Background: During the coronavirus disease 2019 (COVID-19) crisis, many things changed in universities around the world. In-person learning was not possible. Instead, courses were offered in digital form. The sudden change posed enormous challenges to universities, students, and teachers. The aim of this study was to investigate the disadvantages as well as the advantages and opportunities of digital learning. Objective: This study investigated the evaluation of an elective module by medical students and teachers in the traditional in-person and virtual teaching forms during the COVID-19 pandemic. Methods: Using the elective module "Sports Medicine," which includes both lectures and practical units, the opinions of the medical students about conventional teaching compared to digital instruction were evaluated. In the winter semester of 2019/2020, all classes were taught face-to-face but had to be switched to virtual teaching in the summer semester of 2020 on an ad hoc basis due to the pandemic. The students were asked to answer questions on general conditions, participant behavior, instructor evaluation, skill acquisition, topic selection, and overall evaluation after both forms of teaching. Likewise, the lecturers of both courses were queried in semiqualitative interviews about the same topics. Descriptive data analysis was performed to process the data. Results: The students perceived digital teaching to be superior in most subareas compared to in-person teaching in terms of framework, instructor evaluation, skill acquisition, topic selection, and overall rating. Medical students seemed to feel better with digital teaching in most areas of evaluation. The lecturers found the new form of teaching rather unsettling and criticized the lack of verbal and especially nonverbal communication as well as the short preparation time for the new challenge. The instructors were uncomfortable with some aspects of the virtual teaching format. Conclusion: In the wake of the COVID-19 pandemic, medical schools should rapidly digitize their teaching offerings and support faculty members in their computer-based competence with continuing education opportunities and time resources.
RESUMO
BACKGROUND: Contact teaching was prohibited by nationwide lockdowns during the COVID-19 pandemic. The scientific literature contains no concrete figures concerning elearning via webinars in the subject of orthopedics and trauma surgery in the context of the COVID-19 pandemic. OBJECTIVE: This research study was established to collect facts and figures about webinars as a representative part of elearning in the subject of orthopedics and trauma surgery in the context of the COVID-19 pandemic. MATERIAL AND METHODS: German-speaking non-commercial and edited webinars, produced by suppliers from Germany were identified using common search engines. Structured interviews with questionnaires about provider, format, and number of participants in the webinars over time, were offered to the operating companies. RESULTS: The study included four suppliers of webinars (AO Online Campus, BVOU Study Club, OU TO GO and WebDGU). There was approval of all operating companies to participate in the interviews and to disclose facts and figures about their webinars. All suppliers showed an increased supply and demand for webinars during the COVID-19 pandemic. DISCUSSION: OU TO GO and BVOU Study Club already offered webinars prior to the COVID-19 pandemic. AO online Campus was designed in addition to the existing portfolio. The supply of WebDGU was newly established. Limitations of this study are the exclusion of commercial suppliers, non-German operating companies and all other types of elearning except webinars. The increased supply and demand for webinars during the COVID-19 pandemic gives hope for further improvement of elearning in the subject of orthopedics and trauma surgery.

BACKGROUND: Simvastatin increases the expression of bone morphogenetic protein 2 (BMP-2) in osteoblasts, therefore it is important to investigate the influence of statins on bone formation, fracture healing and implant integration. The aim of the present study was to investigate the effect of simvastatin, locally applied from intramedullary coated and bioactive implants, on bone integration using biomechanical and histomorphometrical analyses. METHODS: Eighty rats received retrograde nailing of the femur with titanium implants: uncoated vs. polymer-only (poly(D,L-lactide)) vs. polymer plus drug coated (either simvastatin low- or high dosed; "SIM low/ high"). Femurs were harvested after 56 days for radiographic and histomorphometric or biomechanical analysis (push-out). RESULTS: Radiographic analysis revealed no pathological findings for animals of the control and SIM low dose group. However, n=2/10 animals of the SIM high group showed osteolysis next to the implant without evidence of bacterial infection determined by microbiological analysis. Biomechanical results showed a significant decrease in fixation strength for SIM high coated implants vs. the control groups (uncoated and PDLLA). Histomorphometry revealed a significantly reduced total as well as direct bone/implant contact for SIM high- implants vs. controls (uncoated and PDLLA-groups). Total contact was reduced for SIM low vs. uncoated controls. Significantly reduced new bone formation was measured around SIM high coated implants vs. both control groups. CONCLUSIONS: This animal study suggests impaired implant integration with local application of simvastatin from intramedullary titanium implants after 8 weeks when compared to uncoated or carrier-only coated controls.

BACKGROUND: An implant coating with poly(D, L-lactide) (PDLLA) releasing incorporated zoledronic acid (ZOL) has already proven to positively effect osteoblasts, to inhibit osteoclasts and to accelerate fracture healing. Aim of this study was to investigate the release kinetics of the chosen coating and the effect of different concentrations of ZOL locally released from this coating on the osseointegration of implants. METHODS: For release kinetics the release of C14-labled ZOL out of the coating was monitored over a period of six weeks in vitro. For testing the osseointegration, titanium Kirschner wires were implanted into the medullary canal of right femurs of 100 Sprague Dawley rats. The animals were divided into five groups receiving implants either uncoated or coated with PDLLA, PDLLA/ZOL low (1.2% w/w) or PDLLA/ZOL high (2% w/w). Additionally, a group with uncoated implants received ZOL intravenously (i.v.). After 56 days animals were sacrificed, femurs dissected and either strength of fixation or histological bone/implant contacts and newly formed bone around the implants were determined. RESULTS: Release kinetics revealed an initial peak in the release of C14-ZOL with a slight further progression over the following weeks. There was no significant enhancement of osseointegration for both groups who received ZOL-coated implants or ZOL i.v. compared to the controls in biomechanical or histological analyses, except for a significant raise in strength of fixation of ZOL i.v. versus PDLLA. CONCLUSIONS: Even though the investigated local ZOL application did not enhance the osseointegration of the implant, the findings might support its application in fracture treatment, since fracture stabilization devices are often explanted after consolidation.

BACKGROUND: Health-related mobile applications (apps) are rapidly increasing in number. There is an urgent need for assessment tools and algorithms that allow the usability and content criteria of these applications to be objectively assessed. The aim of this work was to establish and validate a concept for orthopedic societies to rate health apps to set a quality standard for their safe use. METHODS: An objective rating concept was created, consisting of nine quality criteria. A self-declaration sheet for app manufacturers was designed. Manufacturers completed the self-declaration, and the app was examined by independent internal reviewers. The pilot validation and analysis were performed on two independent health applications. An algorithm for orthopedic societies was created based on the experiences in this study flow. RESULTS: "Sprunggelenks-App" was approved by the reviewers with 45 (98%) fulfilled criteria and one (2%) unfulfilled criterion. "Therapie-App" was approved, with 28 (61%) met criteria, 6 (13%) unfulfilled criteria and 12 (26%) criteria that could not be assessed. The self-declaration completed by the app manufacturer is recommended, followed by a legal and technical rating performed by an external institution. When rated positive, the societies' internal review using independent raters can be performed. In case of a positive rating, a visual certification can be granted to the manufacturer for a certain time frame. CONCLUSION: An objective rating algorithm is proposed for the assessment of digital health applications. This can help societies to improve the quality assessment, quality assurance and patient safety of those apps. The proposed concept must be further validated for inter-rater consistency and reliability.

INTRODUCTION: Due to the Covid-19 pandemic, making more use of remote medical solutions has been advertised. The purpose of this study was to assess the willingness of orthopedic trauma patients to conduct an online video consultation (OVC) during the coronavirus pandemic compared to before. METHODS: A survey amongst orthopedic and trauma outpatients from three European trauma centers was conducted via paper-based questionnaires, composed of participants' demographics and five open and closed questions between June and November 2019 and between April and July 2020 during Covid-19. The main outcome was the difference between the cohorts regarding the willingness to use an OVC, reasons for and against usage as well as advantages and disadvantages. Sub-analysis was performed for gender, participants' occupation and three age groups (≤ 30 years; 31-55 years; > 55 years). RESULTS: 1400 participants (780 preCovid-19 and 620 Covid-19) were included. There was no difference in willingness to conduct an OVC between the cohorts (57.6% versus 63.9%; p = 0.053). The highest disposition towards an OVC in both cohorts was seen in patients below 30 years of age, followed by 31-55 years and over 55 years. Women were significantly more likely in the Covid-19-group than in the preCovid-19-group to conduct an OVC (p = 0.032). Use of the OVC for "personal questions to the physician" was more often stated in the Covid-19-cohort (p = 0.007). "No danger of an infection" (p = 0.001) and "availability from anywhere" (p = 0.032) as advantages of an OVC were more often stated in the Covid-19-cohort. "No direct contact with the doctor" (p = 0.001) and "relationship to the doctor could change" (p = 0.024) as disadvantages of the OVC were less often stated in the Covid-19-cohort. CONCLUSION: The majority of the assessed outpatients would use an OVC. Fear of infections have increased, and direct physical contact is less important since the Covid-19 pandemic, but have not increased the disposition for an OVC significantly.

Objectives: Floods, earthquakes and terror attacks in recent years emphasize the importance of disaster preparedness for the medical community. To best prepare doctors for providing optimal care in disaster situations, specific education and training should start at the medical school level. This study containes an online survey among German medical schools to evaluate the status quo of teaching disaster medicine and to reveal potential obstacles. Methods: The dean's offices of 36 German medical schools were contacted from April 2016 to May 2017. Via an e-mail link, recipients could anonymously and voluntarily access an online questionnaire (74 items, 42 with a four-point "Likert-like" scale, 12 yes/no questions and 20 with listed items to choose from). The answers were analyzed by descriptive statistics. Results: A total of 25 medical schools participated in the survey. Twenty respondents were in favor of expanding disaster medicine teaching at their institutions. Incorporating single topics ranging from triage (n=21) to accidents involving radioactive materials (n=4) into the curriculum varied widely. Only two schools had established a teaching coordinator for disaster medicine and only one e-learning course had been established. Twenty-one respondents regarded funding issues and 18 regarded organizational matters to be major hurdles in the future. Conclusion: Though most faculty representatives indicated that they favor expanding and implementing disaster medicine education, German medical schools still have a lot of room for enhancement in this field. The incorporation of e-learning tools could facilitate the expansion of disaster medicine teaching while simultaneously addressing the expressed concerns of the survey's participants and guarantee nationwide standardization.

BACKGROUND: Artificial intelligence (AI) is one of the most promising areas in medicine with many possibilities for improving health and wellness. Already today, diagnostic decision support systems may help patients to estimate the severity of their complaints. This fictional case study aimed to test the diagnostic potential of an AI algorithm for common sports injuries and pathologies. METHODS: Based on a literature review and clinical expert experience, five fictional "common" cases of acute, and subacute injuries or chronic sport-related pathologies were created: Concussion, ankle sprain, muscle pain, chronic knee instability (after ACL rupture) and tennis elbow. The symptoms of these cases were entered into a freely available chatbot-guided AI app and its diagnoses were compared to the pre-defined injuries and pathologies. RESULTS: A mean of 25-36 questions were asked by the app per patient, with optional explanations of certain questions or illustrative photos on demand. It was stressed, that the symptom analysis would not replace a doctor's consultation. A 23-yr-old male patient case with a mild concussion was correctly diagnosed. An ankle sprain of a 27-yr-old female without ligament or bony lesions was also detected and an ER visit was suggested. Muscle pain in the thigh of a 19-yr-old male was correctly diagnosed. In the case of a 26-yr-old male with chronic ACL instability, the algorithm did not sufficiently cover the chronic aspect of the pathology, but the given recommendation of seeing a doctor would have helped the patient. Finally, the condition of the chronic epicondylitis in a 41-yr-old male was correctly detected. CONCLUSIONS: All chosen injuries and pathologies were either correctly diagnosed or at least tagged with the right advice of when it is urgent for seeking a medical specialist. However, the quality of AI-based results could presumably depend on the data-driven experience of these programs as well as on the understanding of their users. Further studies should compare existing AI programs and their diagnostic accuracy for medical injuries and pathologies.
RESUMO
INTRODUCTION: The purpose of the present study was to assess orthopedic and orthopedic trauma patients' willingness to perform hypothetical remote video consultations, possible advantages as well as concerns. METHODS: Between June 2019 and November 2019, a survey amongst consecutive regular orthopedic and orthopedic trauma patients at the outpatient clinics from three European level I trauma centers was conducted via paper-based questionnaires, composed of participants` demographics as well as five open and closed questions. Participation was voluntary and anonymity was granted. RESULTS: In total, 780 participants (female 302, 38.7%, male 478, 61.3%) with a mean age of 43.8 years (SD 17.1, range from 14 years to 94 years) were included. The majority of the participants (57,6%) were eager to use a remote consultation. Participants with an age of more than 55 years were significantly less likely to use a remote consultation than their younger counterparts (OR= 0.18, p=0.003. r2=0.141). Among the whole study population, 86.2% stated, that they had a device compatible with an online video consultation. The highest willingness to conduct a video consultation in respect of the participants` occupation was observed in "part-time"-jobs (70.6%), whereas the lowest disposition was seen in retired patients (37.1%) (p= 0.0001). The most stated reason why to conduct a video consultation was "communication of medical findings" (67.8%). The most stated advantage was the "reduction of physical consultations" (66.4%). "No physical examination" was the most frequently stated disadvantage (75.9%). CONCLUSION: The majority of orthopedic and orthopedic trauma outpatients would use a video consultation, especially because of commuting and time issues and ideally to communicate medical findings, such as x-ray reports or lab values. Elderly patients appear to be less eager in regard to video consultations. These results may change for even better acceptance in view of a current pandemic situation, as experienced since early 2020. We feel that this assumption may warrant further investigation.

INTRODUCTION: Despite a high complication rate, subjective and objective results of reversed shoulder arthroplasty for severe rotator cuff lesions associated with osteoarthritis, fracture sequelae, or revision of hemiarthroplasty are favorable. However, whether the changes in biomechanics of the joint may lead to structural changes in the remaining rotator cuff and the deltoid muscle, and may thereby alter the clinical result, has rarely been described. This study investigates the context between postoperative fatty infiltration of the remaining rotator cuff and the deltoid muscle, and the clinical outcome after reversed shoulder arthroplasty. METHODS: Twenty-three patients with an average age of 73.1 +/- 5.6 years were evaluated at an average of 26 +/- 16.8 months. Evaluation included assessment of Constant Score, disabilities of the arm, shoulder and hand score, radiographic evaluation with measurement of the humeral lengthening and medialization of the center of rotation, and magnetic resonance imaging or computed tomography to classify changes in the rotator cuff and the deltoid muscle. Results There was a significant correlation between fatty infiltration of the deltoid muscle and the clinical score results. Patients with a longer follow-up showed a higher amount of degenerative changes of the deltoid than patients with a shorter follow-up. Degenerative changes of the rotator cuff showed no significant correlation to clinical results. The amount of arm lengthening, medialization of the center of rotation, and scapula notching showed no correlation to clinical results or degenerative changes of the deltoid and the rotator cuff. CONCLUSIONS: These data show that degeneration of the deltoid muscle is of impact for clinical outcome. Although other factors like disuse or pain as a reason for muscular changes cannot be fully excluded, this degeneration might occur after time due to biomechanical changes after reversed arthroplasty. However, prospective studies with longer follow-up periods and repetitive assessment of muscle quality are necessary to further support these results.

Artificial intelligence (AI) is a very relevant topic for the medicine of the future. This article focuses on the field of AI in the context of orthopedics and trauma surgery. The main focus is on the potentials of AI in the analysis of symptoms, radiological images, clinical data sets, use in hospitals and operating theaters as well as for training and education. For the orthopedics and trauma surgery of the future AI is much more than pure fiction; however, there is still a long way to go before the potential of an optimized and individualized patient care can be utilized. Interdisciplinary and international approaches, including personnel, economic, legal and ethical aspects will play a decisive role in this respect.
