Background: Despite major achievements, such as the development of hip prostheses, scientific productivity in orthopaedics and trauma surgery has hardly been investigated. Our study's aim therefore was to analyse the correlation between the leading physicians' h-index and their academic rang, in order to determine whether this objective measure of scientific accomplishments correlates with clinical position.

Methods: All physicians in leading positions at university hospitals' orthopaedics or trauma surgery departments in Germany, Austria, and Switzerland were included. Year of habilitation, number of publications and citations as well as h-index were collected from September to November 2020.

Results: A total of 844 leading physicians at 46 university hospitals were included. Professors had the highest number of total publications (117.4 ± 124.8, p < 0.001) and highest h-index (20.1 ± 10.1, p < 0.001). We found significant differences in the total number of publications (p = 0.001), publications in the last three years (p < 0.001), and h-index (p < 0.001) between the three investigated nations, with all parameters being highest in Switzerland.

Conclusion: Our study shows that increasing scientific productivity is correlated with academic success. The country-specific differences indicate significant differences in the value of scientific activity in daily clinical routine.

Introduction: In the treatment of upper cervical spine injuries, the semiconservative procedure of the halofixator is now of only secondary importance. Older studies from the 2000 s showed unsatisfactory rates of consolidation as well as high rates of complications. However, due to current data on therapy effectiveness, the literature is inconsistent. The aim of this work is to compare our own experiences and results of treatment with the current literature and to help to clarify the role of the halofixator.

Material and methods: In a monocentric retrospective cohort study, patients with unstable injuries of the axial cervical spine who were to be treated in the halofixator were investigated. Individual variables (sex, age, concomitant diseases, Charlson Comorbidity Index) and treatment characteristics (duration of treatment, consolidation status, complications) were recorded using the electronic medical record. Injuries were classified based on CT data at the time of the accident and at the end of treatment, using common classification systems, and assessed with respect to the rate of consolidation. Possible factors influencing bony consolidation as well as complications were statistically analysed.

Results: A total of 54 patients met the inclusion criteria. The median duration of treatment was 83 days. The most common injuries were isolated atlas fracture type III (7; 13%) and isolated dens fracture type III (24; 44%). Bony consolidation was demonstrated in 34 cases (63%) and tight pseudarthrosis in 13 cases (24%). Secondary surgical stabilisation was performed in 6 cases (11%). Isolated type III atlas fractures and type III dens fractures had very high consolidation rates of 86% and 92%, respectively. In the subgroups of patients older than 65 years or with a CCI ≥ 4, unstable pseudarthroses were found more frequently. Complications included pin infection (6%), pin dislocation (9%), and pressure ulceration from the halo vest (6%). Cardiopulmonary complications did not occur. No patient died.

Discussion: Good rates of bony consolidation were seen for atlas fractures type III as well as dens fractures type III, which correlate with data in the literature. Dens fractures type II (isolated and combined) and atlas fractures type III in combination with dens fractures showed a worse radiological outcome, which is also unsatisfactory compared to the literature. The rates for procedure-specific complications were relatively low. In particular, work from recent years has demonstrated very good rates for bony consolidation and low complication rates for the treatment of atlas and/or dens fractures with the halofixator, which are confirmed by our results. In contrast, however, a significantly higher cardiac/respiratory complication rate has been reported than occurred in our own patient population.

There has been a growing shortage of physicians in Germany in recent years. In this study, we analyse the situation facing orthopaedic hospitals and trauma centres.Between 22 November and 5 December 2022, a web-based questionnaire was sent out by the Academy of the German Trauma Society (AUC) and by the Society of Leading Orthopaedic and Trauma Surgeons (VLOU).The questionnaire was answered by 185 heads of department. Of the responses, 20% came from university hospitals or major trauma centres, and a third from regional or local clinics. More than half of the hospital departments (55%) had a median of 2.7 vacant doctor positions. Among those hospitals, 47% had a vacant position for a consultant, 33% for a board-certified specialist, and 89% for a junior doctor. Within the university hospitals, only one third had vacant doctor positions. The responding heads of department gave negative feedback regarding the number of applications, the qualifications of young doctors, and their motivation for scientific work (in university hospitals).More than half of the responding hospitals had vacant doctor positions. If we are to counteract the growing shortage of doctors in orthopaedics and trauma surgery, the number of clinical doctors in general and the working conditions in hospitals have to be improved. Teaching hospitals should try to improve the training of medical students with a view to inspiring greater motivation to work in orthopaedics and trauma surgery.

Case: Two months after anterior shoulder dislocation and spontaneous reduction, a 41-year-old man presented movement-related shoulder pain and a functional deficit. An initially missed osteochondral shearing injury of the humeral head with a Bankart lesion was diagnosed. Due to an extensive posteroinferior defect, an open reduction and internal fixation (ORIF) using bioabsorbable chondral darts was performed. At the 1-year follow-up, magnetic resonance images showed a completely healed osteochondral fragment and the patient presented an unrestricted shoulder function.

Conclusion: Even in missed osteochondral shear injuries, ORIF with bioabsorbable implants can be associated with an excellent functional outcome and sufficient integrity of the fragment. The absorbable implants are biocompatible, therefore the risk of revision surgery due to implant irritations is minimized.

Introduction: In 2020, the SARS-CoV-2 pandemic necessitated an adjustment to the care structure in all medical facilities in Germany. In this study we analysed the effects of the SARS-CoV-2 pandemic using the data from the annual balance sheet of a university department and maximum care provider for orthopaedics and trauma surgery.

Methods: Data analysis was performed on the clinic's performance parameters from 2019 and 2020. The analysis included 52943 outpatient and 7980 inpatient cases, together with the Case Mix Index (CMI), and the costs and revenues.

Results: As a result of the reduction in scheduled surgeries, the mean number of inpatients in March and April 2020 decreased by 10.4% (p = 0.004). Due to the focus on complex cases, the CMI increased by 29.5% (p = 0.007). The number of outpatient surgical procedures increased by 16.9% (n = 84). Rising costs of consumables due to the purchase of protective equipment were offset by a reduced need for orthopaedic implants.

Conclusion: By reducing the number of elective inpatient surgical treatments, the focus was shifted to treating complex cases; this is reflected in the increased CMI. Due to internal compensation mechanisms, the clinic was able to conserve intensive care capacities while still achieving an increase in revenue.

Background: The subjective evaluation of the patient's state of health with the help of Patient-reported Outcome Measurements (PROMs) provides valuable information for assessing the treatment outcome and for treatment planning. However, the use of PROMs in the field of arthroplasty is not mandatory, so that there is a lack of standardised recording and interpretation. The present study aims to identify patients, who have not achieved the intended treatment goals with regard to pain, function and quality of life after total knee arthroplasty, more easily in the future on the basis of postoperative PROMs.

Material and methods: Data collection (for 3-month postoperative follow-up) included a standardised clinical follow-up (NU) and a questionnaire of different PROMs (Oxford Knee Score [OKS], OKS Pain Score [OKSS] and EndoCert Risk Score [ERS]). During the specialist follow-up examination, it was decided whether further medical therapy had to be initiated. Accordingly, patients were grouped into four post-treatment categories (NU not required/further diagnostics/new prescription/revision required).

Results: For individual scores and questions, there were significant differences between the respective groups of consequences resulting from the follow-up examination. The OKS, OKS Pain Score and the ERS are suitable for detecting thresholds to determine the need for a follow-up examination. The postoperative thresholds of the scores are 24 for the OKS total score, 52 for the OKS pain score and 4 for the ERS pain intensity score.

Conclusion: In the initial three months after knee arthroplasty, certain PROMs are suitable for identifying patients for whom further diagnostics and therapy are indicated. In particular, the OKS and the pain intensity score of the ERS are suitable for detecting a potentially unfavourable development in rehabilitation after total knee arthroplasty.

Primary arthroplasty for fractures of the femoral neck is a very common procedure and even the gold standard for the geriatric patient. In contrast, primary arthroplasty for perigenicular fractures is a rare event. On the other hand, it can be a therapeutic option, especially for geriatric patients with prior osteoarthritis or complex fractures and severe osteoporosis.The operative procedure can be complex and requires experience in primary and revision arthroplasty as well as suitable implants and good preoperative planning.There are case series reporting primary arthroplasty in a total of approximately 200 cases of both distal femoral and proximal tibial fractures. Complication rates are between 0 and 90% and mostly concern wound healing problems and infections. From a functional point of view, predominantly good results and a range of motion of 100° can be achieved.Primary arthroplasty can be a therapeutic option for selected cases of perigenicular fractures and gives good functional results. The most frequent complications are wound healing problems and infections.

We report a case of a patient who was treated in 1999 at the age of 19 years with a proximal femur replacement due to Ewing sarcoma. After several infection-associated exchange procedures, the patient presented with a fistula and chronic infection of a total femur prosthesis in August 2019 at the age of 40 years. Interdisciplinary treatment with a 3-stage exchange procedure and implantation of a silver-coated total femur prosthesis was successfully performed and hip disarticulation could be avoided. After a follow-up of 2 years, the patient showed uneventful wound healing and full weight bearing without crutches.
