Global experience of orthopaedic trauma surgeons facing COVID-19: a survey highlighting the global orthopaedic response.

BACKGROUND: The COVID-19 (SARS-CoV-2) pandemic has significantly affected all aspects of healthcare, including orthopaedics. Due to the unique challenges presented by COVID-19 as well as the distinct timeframes that it will surge in different geographies, much can be learned from the experiences of orthopaedic professionals in many global settings. The goal of this project is to characterize the preparations, strategies, lessons, and personal experiences of orthopaedic trauma surgeons and departments across the world in combating COVID-19. In doing so, we will shed light on current practices and challenges, which may help us manage the current pandemic in addition to preparing for future global pandemics that may arise. METHODS: A 20-item questionnaire was sent out to 150 orthopaedic trauma surgeons representing 42 countries who were identified based on professional relationships and/or prior involvement in international meetings either led or participated by the senior author. RESULTS: The questionnaire was completed by 63 orthopaedic trauma surgeons representing 28 countries and 14 US states. The results of this study show that orthopaedic trauma departments across the world have been greatly impacted by COVID-19 with 91% of participating hospitals currently having a reduced case load compared with pre-COVID-19 and only 17% of respondents currently performing elective orthopaedic surgery. Furthermore, 30% of orthopaedic departments have deployed orthopaedic personnel to non-orthopaedic floors in order to help mitigate the increased patient load and 86% of respondents noted at least some shortage of PPE. Lastly 73% of participating orthopedic departments including those in LMICs, have incorporated telemedicine into their practice with a majority stating that it would most likely become a permanent change to their practice post-COVID-19. CONCLUSION: To our knowledge, this is the largest data set characterizing global COVID-19 situations and responses of orthopaedic trauma practices around the world. There is much to be learned from each of the participants' responses in order to persevere during the current pandemic, as well as to prepare for future pandemics as it relates specifically to orthopaedic trauma practices.

Mobility concepts and access to health care in a rural district in Germany: a mixed methods approach.

BACKGROUND: Western countries are facing the challenges of an imminent shortage of physicians, especially general practitioners. As a consequence longer travel times to doctors' practices may arise. This study aimed to investigate the mobility behavior of a rural population in terms of medical consultations. METHODS: An exploratory mixed-methods design was conducted in the Waldshut district of the federal state Baden-Württemberg in Germany. Focus groups and a single telephone-interview with representatives, occupationally affiliated with mobility in the district (e.g. representatives of public transport, nursing-services or the District Office Waldshut), were performed in 2016 and analyzed using Mayring's structuring content analysis. A questionnaire based on the collected qualitative data was subsequently distributed to a random sample of 1000 adult inhabitants living in the Waldshut district. Quantitative data were analyzed employing descriptive statistics. RESULTS: Qualitatively, four focus groups and one single telephone-interview with a total of 20 participants were performed. Therein the necessity of reaching a nearby general practitioner and the importance of individual motor traffic was emphasized. Novel mobility modes of ride sharing and telemedicine were controversially discussed as future transport and consultation options, respectively. Quantitatively, 277 questionnaires (27.7%) were valid and included in our analysis. Mean age was 51 years (SD = 18.5) and 58% (n = 160) were female. Irrespective of the mode of transport 60% (n = 166) expected to reach their general practitioner within 15 min. Using the possibility of multiple answers 47% (n = 192) stated to use a car in order to reach their general practitioner, public transport was used by 5% (n = 19). Nearly 80% (n = 220) could imagine sharing a car with well-known persons for consultations. Turning to a general practitioner via telemedicine was imaginable for 32% (n = 91). CONCLUSIONS: Individual motor car traffic seems to be an important factor in providing accessibility to rural medical care. As a supplementation, web based ride sharing has economic and structural potential for reaching a doctor's practice. However, familiarity and trustworthiness need to be guaranteed within this flexible transport mode. Furthermore, telemedicine may be a future approach in order to reduce travel time to a doctor's practice.

Novel strategies for the synthesis of unsymmetrical glycosyl disulfides.

Novel strategies for the efficient synthesis of unsymmetrical glycosyl disulfides are reported. Glycosyl disulfides are increasingly important as glycomimetics and molecular probes in glycobiology. Sialosyl disulfides are synthesised directly from the chlorosialoside Neu5Ac2Cl, proceeding via a thiol-disulfide exchange reaction between the sialosyl thiolate and symmetrical disulfides. This methodology was adapted and found to be successfully applicable to the synthesis of unsymmetrical glucosyl disulfides under mild conditions.

["Tit for Tat?" The development of prosocial behavior and its relationship to externalizing and internalizing problems]. / Wie du mir, so ich dir? Die Entwicklung von prosozialem Verhalten und der Zusammenhang mit externalisierenden und internalisierenden Auffälligkeiten

Supporting other human beings is a fundamental aspect of human societies. Such so-called prosocial behavior is expressed in helping others, cooperating and sharing with them. This article gives an overview both of the development of prosocial behavior across childhood and of the relationship between prosociality and externalizing and internalizing problems. Especially externalizing problems are negatively associated with prosocial behavior, whereas the relationships with prosocial behavior are more heterogeneous for internalizing problems. Studies investigating developmental trajectories demonstrate that prosocial behavior and externalizing problems are not opposite ends of a continuum. Rather, they are two independent dimensions that may also co-occur in development. The same applies to internalizing problems, which can co-occur with pronounced prosociality as well as with low prosociality.

Telling a "baby story": mothers narrating their pre-schoolers' past across two cultural contexts.

Mothers from two middle-class contexts from Berlin, Germany (n = 35), and Delhi, India (n = 28) told a baby story to their 3-year olds about an event that had happened during the children's first year of life. The contexts represented two cultural models: the model of psychological autonomy (Berlin) and the model of autonomy-relatedness (Delhi). We investigated the culture-specific functions of this reminiscing task as reflected in the structure, content and specificity of the stories. The stories in both contexts were minimally interactive and the children contributed few elaborations themselves. Stories told by the Berlin mothers were longer, and more specific. Mothers in both contexts were similarly elaborative relative to being repetitive. The stories were highly child-centred in both contexts but even more child-centred for Delhi. Importantly, maternal narrations from the Berlin context were embedded in a frame story that characterised the child's individual past; stories thus constructed "exclusive baby stories". Most stories told by the Delhi mothers had no frame story but instead were about what the child used to do as a baby in general; they thus constructed "routine baby stories". Results are interpreted in the view of the underlying self, social and directive functions of this reminiscing task.

Evaluating the interactions between vibrational modes and electronic transitions using frontier orbital energy derivatives.

Vibrations affect molecular optoelectronic properties, even at zero kelvin. Accounting for these effects using computational modelling is costly, as it requires many calculations at geometries distorted from equilibrium. Here, we propose a low-cost method for identifying vibrations most strongly coupled to the electronic structure, based on using orbital energy derivatives as a diagnostic.

Three-Dimensional Mapping of Scapular Body, Neck, and Glenoid Fractures.

OBJECTIVES: The purpose of this study was to report patterns of scapular fractures and define them with a contemporary methodology. METHODS: . DESIGN: Retrospective study, 2015-2021. SETTING: Single, academic, Level 1 trauma center. PATIENT SELECTION CRITERIA: Consecutive patients ≥18 years, presenting with unilateral scapula fracture, with thin-slice (≤0.5-mm) bilateral computed tomography (CT) scans of the entirety of both the injured and uninjured scapulae. OUTCOME MEASURES AND COMPARISONS: Thin-slice (0.5-mm) CT scans of injured and normal scapulae were obtained to create three-dimensional (3D) virtual models. 3D modeling software (Stryker Orthopedics Modeling and Analytics, Stryker Trauma GmbH, Kiel, Germany aka SOMA) was used to create a 3D map of fracture location and frequency. Fracture zones were delineated using anatomic landmarks to characterize fracture patterns. RESULTS: Eighty-seven patients were identified with 75 (86%) extra-articular and 12 (14%) intra-articular fractures. The dominant fracture pattern emanated from the superior lateral border (zone E) to an area inferior to the spinomedial angle (zone B) and was present in 80% of extra-articular fractures. A second-most common fracture line propagated from the primary (most-common) line toward the inferior medial scapular border with a frequency of 36%. Bare zones (with 1 or no fractures present) were identified in 4 unique areas. Furthermore, intra-articular fractures were found to be heterogenous. CONCLUSIONS: The 3D fracture map created in this study confirmed that extra-articular scapular fractures occur in certain patterns with a relatively high frequency. Results provide greater insight into scapular fracture locations and may help to study prognosis of injury and improve treatment strategy including operative approaches and surgical tactics.

Making sense of the pandemic: Parent-child conversations in two cultural contexts.

The present study focused on parent-child conversations about COVID-19 related changes in children's lives in Estonia and Germany with an aim to understand how children's conceptual understanding of the disease and their emotional security is created and reflected in these interactions. Twenty-nine parent-child dyads from both cultural contexts provided self-recorded conversations. The conversations were analyzed for the type of explanations, emotional content, and valence. Estonian conversations were longer than those of German dyads. Explanatory talk appeared in both contexts but was general in nature. Conversations in both cultural contexts also included very few emotional references and tended to focus on both positive and negative aspects of the situation. The conversations show that parents tend to support children's coping with stressful situations by helping them conceptually understand COVID-19 and paying little attention to children's comprehension of feelings about the situation.

Rib Fracture Map in High-Energy Injuries.

OBJECTIVES: To use a novel rib unfurling technology to investigate the locations of multiple rib fractures occurring from high-energy trauma to discern if there are reproducible rib fracture patterns. METHODS: Patients between the ages of 18 and 48 years presenting to a Level 1 academic trauma center with ≥2 rib fractures after a high-energy mechanism of injury between 2017 and 2019 were identified. Curved planar reformatting of CT scans was used to create two-dimensional unfurled rib images by flattening out the view of the ribs from a CT scan. Rib fractures were placed on a template map using a standardized measurement method, and subsequent frequency and heat maps were created. RESULTS: Among 100 consecutive patients, 534 fractures on 454 ribs were identified. The most common high-energy mechanism of injury was motor vehicle accidents (41%). Flail chest occurred in 8% of patients. The mean number of ribs fractured per patient was 4.54 ± 3.14 and included a mean of 5.34 ± 4.38 total fractures. Among all fractures, 50.9% were located on ribs 4 through 7. The most common fracture location was located in the lateral or anterolateral zone of the rib cage. CONCLUSIONS: Patients with multiple rib fractures from high-energy trauma have rib fractures with locations of common occurrence. An understanding of location and frequency of rib fractures can help inform surgical approaches, prognosis, indications, classifications, and implant design in the management of a complex population of patients with chest wall injury after trauma.

Effectiveness of an Orthopaedic Trauma Research Fellowship to Produce Successfully Matching Residents.

OBJECTIVE: Orthopaedics is becoming increasingly competitive. Approximately 25% of applicants to orthopaedic surgery go unmatched each year. The mean US Medical Licensing Examination step scores and average publication numbers have increased markedly in recent years. Reapplicants have a match rate of <60%. This study describes the results of an orthopaedic trauma research fellowship and its effectiveness in obtaining a successful orthopaedic match. METHODS: A 1 to 2-year research fellowship was established at a level 1 academic trauma center. Prefellowship and fellowship metrics of 11 fellows were recorded, including undergraduate and medical schools; step-1 + step-2 scores; Alpha Omega Alpha appointment; and publication, podium, poster, and chapter accomplishments. RESULTS: The average step-1 score of the fellows was 218 (range, 192 to 252) and 232 (range, 212 to 254) for step-2. Seven of 11 fellows were reapplicants. Prefellowship, the average number of journal publications was 1, one podium, two posters, and zero textbook chapters. During fellowship, the average publications was 5, five podiums, six posters, and 1.5 textbook chapters. Ten of 11 fellows successfully matched into an orthopaedic residency, with six of seven being reapplicants. CONCLUSIONS: Six of 7 reapplying fellows (86%) successfully matched highlighting the effectiveness of this fellowship. Research fellowships should be considered as an excellent choice for applicants who may be less than ideal candidates or reapplicants.

Exposing the Care Conundrum of Low-Energy Pelvic Ring Fractures in Older Adults: A Review of 322 Patients.

Introduction: A care conundrum for low-energy pelvic ring fracture patients in which they face financial burden after not qualifying for an inpatient stay of 3 days or more has been noted in the literature. The purpose of this study was to identify factors that lead to inpatient length of stay (IP LOS) ≥3 days in older adults with nonoperative pelvic ring fragility fractures and to highlight the challenging financial decision-making of those with IP LOS <3 days in the context of the Medicare 3-day rule. Methods: This was a retrospective review of 322 patients aged ≥65 presenting from March 2016 and February 2019 to either of 2 emergency departments (EDs) after a ground-level fall resulting in a pelvic ring fracture. Patient demographic, IP LOS, and mortality data were extracted. Case management notes were analyzed to summarize financial decision-making for patients with IP LOS <3 days. Multivariate logistic regression analysis was conducted to identify factors that predicted IP LOS ≥3 days and mortality. Results: IP LOS ≥3 days was associated with presentation to level I hospital (OR .30 [.19, 0.50]) and being single (OR 2.50 [1.10, 5.68]). 70.3% required a post-acute skilled nursing facility (SNF) stay. Of patients with LOS <3 days, 25.0% were financially responsible for their SNF stay, while 7.9% elected home care due to financial reasons. Overall 30-day, 90-day, and 1-year mortality were 2.5%, 8.1%, and 20.8%, respectively. For patients with LOS <3 days, returning to assisted living compared to discharging to a SNF increased 90-day mortality risk (HR 8.529, P = .0451). Having Medicare trended towards increased 90-day mortality risk compared to commercial insurance (HR 4.556, P = .0544). Conclusion: The current system is failing older adult patients who sustain nonoperative low-energy pelvic ring fractures in terms of financial coverage of necessary post-acute treatment. This care conundrum has yet to be solved.

Content of maternal open-ended questions and statements in reminiscing with their 4-year-olds: links with independence and interdependence orientation in European contexts.

Mother's open-ended questions and elaborative statements during reminiscing were analysed for their content (child agency, co-agency, non-social, and social context) in three cultural contexts. Participants were 115 mothers and their 4-year-old children: 35 dyads from Berlin, Germany, 42 from Stockholm, Sweden, and 38 from Tallinn, Estonia. Across samples the most prominent content was talk about non-social context followed by co-agency and child agency. Tallinn mothers asked the children to talk about themselves, and Berlin mothers asked the children to talk about themselves together with other people, more frequently than they talked about these contents themselves. The content was related to the cultural orientations of mothers assessed through questionnaires: the Berlin mothers whose independence/ interdependence ratio was higher talked less about other people and asked the children fewer questions about other people; the Stockholm mothers with a higher independence/interdependence ratio talked more about child agency. In Tallinn both correlations existed on a trend level. The results are discussed in the light of common conversational practices and mothers' orientation to independence and interdependence in these cultural contexts.

Management of scapular fractures.

With the exception of displaced articular glenoid fractures, management of scapular fractures has largely consisted of benign neglect, with an emphasis on motion as allowed by the patient's pain. Better understanding of this injury has resulted in greater acceptance of surgical management of highly displaced variants. However, little agreement exists on indications for surgery, and there is no clear comparative evidence on outcomes for surgically versus nonsurgically managed fractures. Scapular fractures are the result of high-energy mechanisms of injury, and they often occur in conjunction with other traumatic injuries. In addition to performing meticulous physical and neurologic examination, the surgeon should obtain plain radiographs, including AP shoulder, axillary, and scapular Y views. Three-dimensional CT is used to determine accurate measurements in surgical candidates. Surgical approach, technique, and timing are individualized based on fracture type and other patient-related factors.

An overview of 3D printing and the orthopaedic application of patient-specific models in malunion surgery.

As the emerging technology of three-dimensional (3D) printing impacts several facets of medicine, innovative techniques and applications are increasingly being incorporated into clinical workflows. Specifically, 3D printing technology has allowed for the individualization of patient care through the creation of printed surgical guides, patient-specific anatomical models, and simulation practice models. In this paper, we review the broad applications of 3D printing in orthopaedic surgery. The purpose of this paper is to help orthopaedic trauma surgeons understand 3D printing's emerging influence on the delivery of care as well as how to directly apply this technology to their practice. We aim to illustrate these principles through a specific example of a patient who presented for malunion surgery. A 3D printed model of a very complex traumatic scapula malunion was used to not only pre-surgically plan the reconstruction, but to also facilitate provider and patient education. This paper highlights the benefits of 3D printing and how trauma surgeons are uniquely positioned to apply this technology to improve patient care.

Outcomes After Operative Reconstruction of Symptomatic Rib Nonunions.

OBJECTIVE: To assess the outcomes of patients after rib nonunion reconstruction. DESIGN: Retrospective case series. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Between January 2007 and August 2019, 25 consecutive patients with 51 nonunions with disabling pain or chronic instability were treated for nonunited rib fractures. INTERVENTION: Rib nonunion reconstructions performed using plate and screw fixation, recannalizing the medullary canal and augmented with autogenous iliac crest bone graft. MAIN OUTCOME MEASUREMENTS: Patient demographics, mechanism of injury, number of rib nonunions, and postoperative radiographs were assessed. Satisfaction, patient-reported complications, return to occupation and activity, and general health measures were captured using patient questionnaires. RESULTS: In 25 patients, 51 painful rib nonunions were surgically treated. The average length from injury to surgical rib reconstruction was 25.1 months (range = 3-118 months; median = 12 months). Follow-up was obtained in 18 of 25 patients (72%) with a mean of 46.1 months (range = 13-139 months). All ribs achieved radiographic union at an average of 12.3 weeks (range = 8-24 weeks) after surgery. Sixteen of 18 patients (89%) reported satisfaction with surgery and 15 patients (83%) reported mild to no pain at final follow-up. Five patients had complications that all resolved after subsequent treatment. CONCLUSIONS: Successful treatment of symptomatic rib nonunion is possible using rib plates in conjunction with bone grafting and has high union rates, satisfactory results, and limited complications. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Hip fracture care during the COVID-19 pandemic: retrospective cohort and literature review.

OBJECTIVES: The goal of this study was to investigate whether the COVID-19 pandemic has affected hip fracture care at a Level I Trauma hospital. The secondary goal was to summarize the published hip fracture reports during the pandemic. DESIGN: A retrospective cohort study. SETTING: Level I Trauma Center. PATIENTS/PARTICIPANTS: Eighty-six operatively treated hip fracture patients age ≥65 years, occurring from January 17 to July 2, 2020. INTERVENTION IF ANY: N/A. MAIN OUTCOME MEASUREMENTS: We defined 3 phases of healthcare system response: pre-COVID-19 (period A), acute phase (period B), and subacute phase (period C). The primary outcome was 30-day mortality. Clinical outcomes including time to surgery (TTS) and length of stay (LOS) were extracted from the electronic medical record. RESULTS: Twenty-seven patients from Period A, 27 patients from Period B, and 32 patients from Period C were included. The 30-day mortality was not statistically different. The mean TTS was 20.0 +/- 14.3 hours and was the longest in Period C (22.1 +/- 9.8 hours), but the difference was not statistically significant. The mean LOS was 113.0 +/- 66.2 hours and was longest in Period B (120.9 +/- 100.6 hours). However, the difference was not statistically significant. CONCLUSIONS: The 30-day mortality, TTS, and LOS were not statistically different across multiple phases of pandemic at a level 1 trauma center. Our results suggest that we successfully adapted new protocol changes and continued to provide evidence-based care for hip fracture patients. Our results were comparable with that of other authors around the world.

Creative bracing: A descriptive overview of an alternative technique for non-operative fracture management of frail older adults.

As the world population ages, a higher proportion of older and frailer patients will sustain fragility fractures. Considering their depleted physiologic reserve and potentially different goals of care at their stage in life, these patients; especially those enrolled in hospice care, with profound dementia, or at end-of-life care; may not benefit from traditional surgical methods of fracture care. Non-operative treatment using standard immobilization or casting techniques in older and frailer patients can still render them susceptible to complications and adverse events. Here we describe our alternative non-operative treatment method of creative bracing to address the needs of this specific population. Creative bracing can be done with simple supplies available in almost all healthcare settings. Through patient-specific pre-treatment assessment, a creative brace tailored to the patient's risk factors and goals of care can be designed to provide sufficient fracture immobilization and comfort. Creative bracing is a low-cost, low-technical demand modality for non-operative treatment of some fragility fractures. Its benefit can be appreciated to greatest effect in the frailest patients for whom standard, surgical treatment does not represent best care.

Hip Fracture Care in Parkinson Disease: A Retrospective Analysis of 1,239 Patients.

Introduction: Compared to other patients, Parkinson disease (PD) patients may experience suboptimal outcomes after hip fracture. The purpose of this study was to describe and compare characteristics and outcomes of hip fracture patients with PD to those without PD. Methods: This retrospective cohort study included all patients admitted for hip fracture within a large healthcare system between July 1, 2017 and June 30, 2019. Demographics, injury characteristics, Charlson Comorbidity Index (CCI), treatment characteristics, and outcomes including complications, readmissions, and mortality were extracted. Patients with PD were compared to those without PD. Chi-square tests, two-sample t-tests, and Fisher exact tests were conducted to identify group differences. Results: A total of 1239 patients were included (4.0% PD and 96.0% non-PD). PD patients were mostly male (59.2%) compared to mostly female non-PD patients 69.4%, P < .001). PD patients on average had a higher CCI (2.3 vs 1.7, P = .040) and more frequently had dementia (42.9% vs 26.7%, P = .013). No PD patients were discharged home without additional assistance compared to 8.1% of patients without PD. More PD patients were discharged to a skilled nursing facility (SNF) than non-PD patients (65.3% vs 48.2%, P = .021). Only 22.4% of PD patients were previously prescribed osteoporosis medication, and only 16.3% were referred for osteoporosis follow-up after fracture. In-house complications, readmissions, and mortality up to 1 year were comparable between groups (P>.191). Conclusions: Outcomes between PD patients and non-PD patients were mostly equivalent, but more PD patients required discharge to a higher-level care environment compared to non-PD patients. Although PD seems to be a risk factor for hip fracture regardless of age and sex, most patients had not undergone proper screening or preventative treatment for osteoporosis. These results emphasize the need for early bone health evaluation, multidisciplinary collaboration, and care coordination in preventing and treating hip fractures in PD.

Capturing patient-reported outcomes: paper versus electronic survey administration.

Objective: To compare the capture rates and costs of paper patient-reported outcomes (pPRO) administered in-clinic and electronic PROs (ePRO) collected through emails and texts. Design: Retrospective review. Setting: Level 1 trauma center. Patients/Participants: The pPRO program enrolled 2164 patients for postsurgical follow-up in 4 fracture types: ankle, distal radius, proximal humerus, and implant removal from 2012 to 2017. The ePRO program enrolled 3096 patients in 13 fracture types from 2018 to 2020. Among the patients enrolled in the ePRO program, 1296 patients were matched to the 4 original fracture types and time points. Main Outcome Measures: PRO capture rates in 4 fracture types by matched time point and estimated cost of each program per enrolled patient. Results: At first follow-up, pPRO provided a higher capture rate than ePRO for 3 of 4 fracture types except for implant removal (P < 0.05). However, at 6-month and 1-year follow-ups, ePRO demonstrated statistically significant higher capture rates when compared with pPRO for all applicable modules (P < 0.05). The average cost for the pPRO program was $171 per patient versus $56 per patient in the ePRO program. Patients were 1.19 times more likely to complete ePRO compared with pPRO (P = 0.007) after controlling for age, sex, fracture type, and time point. Conclusion: The electronic PRO service has improved long-term capture rates compared with paper PROs, while minimizing cost. A combined program that includes both in-clinic and out of clinic effort may be the ideal model for collection of PROs. Level of Evidence: Level 3.

In Situ Reconstruction of a Painful Sternal Z-Deformity Nonunion in a Severely Osteoporotic and Kyphotic Patient: A Case Report.

CASE: An osteoporotic and kyphotic 72-year-old woman presented with sternal pain, severe chest instability, and shortness of breath secondary to a traumatic sternal nonunion resulting from an unhealed sternal fracture sustained in a motor vehicle accident several months earlier. One-year functional and radiographic outcomes are presented with complete resolution of symptoms. CONCLUSION: Consideration for treatment with multiplanar, contourable, locked plating, augmented by autogenous graft, is warranted in the setting of sternal deformity and nonunion, particularly in the setting of osteoporosis and other sagittal plane deformity.
