Does delayed weight bearing in the surgical management of fractures of the upper end of the femur in the elderly lead to more complications? A prospective study

INTRODUCTION

Fractures of the upper end of the femur (FUEF) lead to increased mortality and dependence in the elderly. However, mechanical complications after surgery persist in up to 20% of cases, which may justify a delayed resumption of full weight bearing to protect the osteosynthesis during consolidation.

HYPOTHESIS

Our hypothesis was that the late resumption of weight bearing in an elderly population after a FUEF would be limited by a higher frequency of medical complications.

METHODS

This was a prospective monocentric study including patients aged 80 or over with an isolated FUEF requiring osteosynthesis. The operator decided on the discharge. The primary endpoint was to show a difference in a medical complication score created for this study (APRETAR), between a group with, and a group without, weight bearing delayed by 45 days.

RESULTS

Between 2016 and 2019, 254 patients (88±5.6 years, 77.6% women) were included, and of these, 70 (27.6%) had delayed weight bearing. The mean APRETAR at 45 days was greater in the delayed weight bearing group (5.9±8.6 vs. 5.7±11.0; p<0.001). One-year mortality was 12.6% (32 patients), with no difference between the two groups (p=0.51). The level of dependence was significant (IADL at 2.2±1.7), with some comorbidities (Charlson at 2.9±2.2 and CIRS-G at 6.5±4.3) and all comparable across the two groups but with low cognitive levels, especially in the group with delayed weight bearing (MMSE 15.9±10.7 vs. 21±6.9; p<0.001).

CONCLUSION

This prospective study shows that delaying weight bearing in the elderly population, even for mechanical problems with FUEF, statistically increases medical complications but in a clinically acceptable manner.

Accuracy of virtual planning and intraoperative navigation in zygomaticomaxillary complex fractures: A systematic review

OBJECTIVE

This systematic review aims to investigate the effect of virtual planning on the treatment of zygomaticomaxillary complex (ZMC) traumatology followed by intraoperative navigation. Furthermore, clinical outcomes following intraoperative navigation surgery or conventional surgery will be compared.

MATERIALS AND METHODS

A systematic literature search was conducted in PubMed, Embase, Web-of-Science, and Cochrane on January 1st, 2022. Inclusion criteria were articles using preoperative three-dimensional (3D) virtual planning combined with intraoperative navigation or comparing these 3D methods with conventional methods. Furthermore, at least one of the following outcomes needed to be included in the article: technical accuracy of the procedure, preoperative planning time, operative time, number of fixation points, patient satisfaction, complications, or total costs of the intervention.

RESULTS

Following the screening of 4478 articles, 17 were included. Five articles appeared to indicate a significantly better technical linear accuracy, one article reported better accuracy for rotation and two articles showed better accuracy in restoring orbital volume when using navigation. Nine articles investigated operative time with varying results. Seven articles calculated the additional costs, of which three concluded no extra cost while the others indicated high additional costs or questionable cost-effectiveness.

CONCLUSION

Virtual planning and intraoperative navigation technologies have the potential to assist maxillofacial trauma surgeons in reducing ZMC fractures significantly more accurately and restoring the facial contour in a less invasive manner at an acceptable cost.

REGISTRATION

The protocol for this systematic review (CRD42020216717) was registered in the International Prospective Register of Systematic Reviews (PROSPERO).

Quantitative ultrasonographic diagnostics for midface and mandible fractures

The aim of this study was to examine whether ultrasonography and three-dimensional radiological procedures produce significantly different measurement results with respect to fracture dislocation. This was a retrospective study of patients who were admitted to the department for oral and maxillofacial surgery of the Medical Highschool Hannover with facial skull fracture and underwent high-resolution computed tomography and ultrasonography imaging during a period from 1 January 2019 to 31 August 2019. A 10 mHz transducer was used for fracture imaging, and the largest dislocation of each fracture was measured. A paired t-test for dependent samples was used for statistical evaluation of the measured differences, and the p-value was set at 0.05. A total of 16 patients with 29 fractures were included. The fractures were characterized as follows: zygomatic arch (n = 7), lateroorbital region (n = 4), maxilla/zygomatic bone (n = 15), mandible (n = 2), and frontal sinus (n = 1). Regardless of the fracture location, we found no statistical difference in fracture measurements between the ultrasonography and the computed tomography (p = 0.17 (fractures of the zygomatic arch) to p = 0.85 (all fractures)). The study findings suggest that ultrasonography not only allows basic detection but also a quantification of the dislocation in facial skull fractures. The ultrasonography results are not significantly different from those of the computed tomography. In everyday clinical practice, ultrasonography of facial fractures can be considered an adequate imaging procedure. If used correctly, additional radiation exposure to the patient can be avoided, thus representing a diagnostic alternative to computed tomography.

Trampoline injuries in children: A prospective study

BACKGROUND

Trampolining is popular and widely practiced among children. A literature review has shown a rise in the incidence of trampoline injuries with a concomitant increase in paediatric emergency department visits. The primary objective of this study was to describe the severity of trampoline injuries in children. The secondary objectives were to assess the epidemiology of the study population and injuries and to describe the treatments.

HYPOTHESIS

We hypothesized that over 10% of trampoline injuries were severe.

MATERIAL AND METHODS

We prospectively evaluated consecutive patients seen for surgical conditions at our paediatric emergency department over a 10-month period. Among them, 103 (1.2% of visits) aged 4 months to 16 years (mean, 8 years) had trampoline injuries. We classified trampoline injuries as severe if they required general anaesthesia.

RESULTS

Severe injuries accounted for 16.5% of all trampoline injuries. The upper limb was predominantly affected (70.6% of cases). Overall, 66.7% of fractures were at the upper limb and 76% of contusions at the lower limb. The predominant fracture sites were the supra-condylar humerus (15.3%) and distal radius (15.3%). Among patients with non-severe injuries, four-fifths left the emergency department with a temporary immobilisation system.

DISCUSSION

The proportion of severe injuries was slightly higher in our study than in earlier reports. Trampoline injuries remain uncommon but can be severe. Thus, in our study over one-sixth of patients required surgery under general anaesthesia.

Risk modeling of femoral neck fracture based on geometric parameters of the proximal epiphysis

BACKGROUND

Fractures of the proximal femur epiphysis are problematic for state health care because they are associated with severe medical and social problems and high morbidity and mortality rates.

AIM

To model the potential risk of hip fracture via femur geometric parameters.

METHODS

Seventy educational cadaveric femurs from people aged 14 to 80 years, 10 X-ray images from the records of the Human Anatomy Department and 10 X-ray images from the Department of Traumatology, Orthopedics and Disaster Surgery of Sechenov University, were evaluated. The parameters of the fractured bone were measured using images captured with a Canon d60 camera. The projection values of the proximal epiphysis of the cadaveric femurs and geometric parameters of the bones shown in the X-ray images were measured with Autodesk software (AutoCAD 2018). Analysis of the video frames showing bone rotation reveal that the greater trochanter can be inscribed in a parallelepiped, where one of the faces is parallel to the plane of view in the frontal standard projection and is rectangular. The angle of bone rotation obtained by turning the cube corresponded to the angle measured with the second technique. This reliable method of calculating the rotation of the bone relative to the anterior projection was employed in subsequent calculations. The geometric parameters of the femur were measured using X-ray images according to the proposed method.

RESULTS

The geometric parameters of 70 femurs were analyzed, and correlation coefficients were calculated. Our measurement results were compared with those reported by other authors. The potential influence of femur geometry on force distribution in the proximal epiphysis of the femur was described, and a 2-dimensional model of the femur epiphysis associated with minimal neck fracture risk was provided. The assessment of the geometric parameters of the femoral epiphysis indicated the greatest risk of a varus fracture of the neck if the angle of the minimal resistance zone (AMRZ) index > 24° and the neck-shaft angle (NSA) < 127.5°. In contrast, the minimum risk was observed at AMRZ < 14° and NSA > 128.87°.

CONCLUSION

The proposed method provides the potential femur neck fracture risk based on geometric parameters.

Equitable access to quality trauma systems in low-income and middle-income countries: assessing gaps and developing priorities in Ghana, Rwanda and South Africa

Injuries in low-income and middle-income countries are prevalent and their number is expected to increase. Death and disability after injury can be reduced if people reach healthcare facilities in a timely manner. Knowledge of barriers to access to quality injury care is necessary to intervene to improve outcomes. We combined a four-delay framework with WHO Building Blocks and Institution of Medicine Quality Outcomes Frameworks to describe barriers to trauma care in three countries in sub-Saharan Africa: Ghana, South Africa and Rwanda. We used a parallel convergent mixed-methods research design, integrating the results to enable a holistic analysis of the barriers to access to quality injury care. Data were collected using surveys of patient experiences of injury care, interviews and focus group discussions with patients and community leaders, and a survey of policy-makers and healthcare leaders on the governance context for injury care. We identified 121 barriers across all three countries. Of these, 31 (25.6%) were shared across countries. More than half (18/31, 58%) were predominantly related to delay 3 (‘Delays to receiving quality care’). The majority of the barriers were captured using just one of the multiple methods, emphasising the need to use multiple methods to identify all barriers. Given there are many barriers to access to quality care for people who have been injured in Rwanda, Ghana and South Africa, but few of these are shared across countries, solutions to overcome these barriers may also be contextually dependent. This suggests the need for rigorous assessments of contexts using multiple data collection methods before developing interventions to improve access to quality care.

Visualization of complicated fractures by 3D-printed models for teaching and surgery: hands-on transitional fractures of the ankle

Aims

Understanding the orientation of fracture lines and mechanisms is the essential key to sufficient surgical therapy, but there is still a lack of visualization and teaching methods in traumatology and fracture theory. 3D-printed models offer easy approach to those fractures. This paper explains the use of the teaching possibility with 3-dimensional models of transitional fractures of the ankle.

Methods and results

For generating 3D printable models, already obtained CT data were used and segmented into its different tissues, especially parts concerning the fracture. After the segmentation process, the models were produced with FFF (fused filament fabrication) printing technology. The fracture models then were used for hands-on teaching courses in AO course (Arbeitsgemeinschaft für Osteosynthesefragen) of pediatric traumatology in 2020 in Frankfurt. In the course fracture anatomy with typical fracture lines, approaches, and screw placement could be shown, discussed and practiced.

Conclusion

The study shows the use of 3D-printed teaching models and helps to understand complicated fractures, in this case, transitional fractures of the ankle. The teaching method can be adapted to numerous other use cases.

Point-of-Care Ultrasound for the Trauma Anesthesiologist

Purpose of Review

With advances in technology and availability of handheld ultrasound probes, studies are focusing on the perioperative care of patients, but a limited number specifically on trauma patients. This review highlights recent findings from studies using point of care ultrasound (POCUS) to improve the care of trauma patients.

Recent Findings

Major findings include the use of POCUS to assess volume status of trauma patients upon arrival to measure the major vasculature. Additionally, several studies have advanced the use of POCUS to identify pneumothorax in trauma patients. Finally, the ASA POCUS certification and ASRA expert guidelines are examples of international organizations establishing guidelines for utilization and training of anesthesiologists in the field of POCUS, which will be discussed.

Summary

Despite the COVID-19 pandemic, and considerable resources being diverted to fight this global healthcare crisis, advances are being made in utilization of POCUS to aid the care of trauma patients.

Individual Pharmacotherapy Management (IPM) - I: a group-matched retrospective controlled clinical study on prevention of complicating delirium in the elderly trauma patients and identification of associated factors

Background

Delirium is one of the most frequent complications in hospitalized elderly patients with additional costs such as prolongation of hospital stays and institutionalization, with risk of reduced functional recovery, long-term cognitive impairment, and increased morbidity and mortality. We analyzed the effect of individual pharmacotherapy management (IPM) in the University Hospital Halle in geriatric trauma patients on complicating delirium and aimed to identify associated factors.

Methods

In a retrospective controlled clinical study of 404 hospitalized trauma patients ≥70 years we compared the IPM intervention group (IG) with a control group (CG) before IPM implementation. Delirium was recorded from the hospital discharge letter. The medication review and data records included baseline data, all medications, diagnoses, electrocardiogram (ECG), laboratory and vital parameters during hospitalization. The IPM internist and the senior trauma physician guaranteed personnel and structural continuity in the implementation of the interdisciplinary patient rounds.

Results

There was a highly matched congruence between CG and IG in terms of age, gender, residency, BMI, most diagnoses, and injury patterns to compare the two groups. The total number of medications per patient was 11.1 ± 4.9 (CG) versus 10.4 ± 3.6 (IG). Our targeted IPM focus on 6 frontline aspects with reduction of antipsychotics, anticholinergic burden, benzodiazepines, serotonergic opioids, elimination of pharmacokinetic and pharmacodynamic drug interactions and overdosage reduced complicating delirium from 5% to almost zero at 0.5%. The association of IPM with a significant 10-fold reduction, OR = 0.09 [95% CI 0.01–0.7], in univariable regression, maintained of clinical relevance in multivariable regression OR = 0.1 [95% CI 0.01–1.1]. Factors most strongly associated with complicating delirium in univariable regression were cognitive dysfunction, nursing home residency, muscle relaxants, antiparkinsonian agents, xanthines, transient disorientation documented in the fall risk scale, antibiotic-requiring infections, antifungals, antipsychotics, and intensive care stay, the two latter maintaining significance in multivariable regression.

Conclusions

IPM is associated with a highly effective prevention of complicating delirium in the elderly trauma patients. For patient safety it should be integrated as an essential preventative contribution. The associated factors help identify patients at risk.

Surgical treatment of post-traumatic luxation of rib heads with spinal cord compression in a cat

BACKGROUND

Luxation of the rib head with intrusion into the intervertebral foramen seems to be rare in cats. Only one report has been published describing a cat with non-ambulatory paraparesis, which was managed conservatively. Here we report a case of rib head luxation that was managed surgically.

CASE PRESENTATION

A 4-year-old, female domestic shorthair cat with a two-week history of non-ambulatory paraparesis was presented at our clinic. Based on history and neurological examination, a diagnosis of thoracolumbar spinal cord lesion of traumatic origin was made. Computed tomography scanning revealed mild scoliosis, a luxation of the 3rd and 4th right rib heads and penetration into the spinal canal through intervertbral foramina. Surgical management using right dorsal approach to the spine was performed. The spinal cord was decompressed by cutting and removing of proximal ribs' fragments by rotation and pulling out from the intervertebral foramina. The cat was ambulatory and paraparetic four weeks after surgery. Two years after surgery the cat regained functional gait, but ataxia remained.

CONCLUSIONS

We report the first case of a surgical treatment of rib head luxation and intrusion into the spinal canal in a cat. The applied procedure resulted in an improvement of neurological signs.

Predicting mortality in trauma patients - A retrospective comparison of the performance of six scoring systems applied to polytrauma patients from the emergency centre of a South African central hospital

Introduction

Over 90% of trauma-related deaths worldwide, ensue in low- and middle-income countries. Multiple useful trauma scoring systems have been devised. Although validated in high-income countries, they cannot always be replicated in resource-limited countries. This study compares six trauma scores to identify the best-suited system to use for polytrauma patients in a hospital in Pretoria, South Africa.

Methods

This is an observational retrospective analysis of polytrauma admissions from 1 July 2016 to 31 December 2016. Data collected from patients' records from the EC of Steve Biko Academic Hospital, was analysed using Stata Release 14. Outcomes were recorded as 30-day survival, ICU– and overall hospital LOS. Scores pertaining to patient mortality, were compared in terms of sensitivity, specificity, and cut-off points based on ROC curve. Finally, for LOS Pearson correlation analysis was used.

Results

At the best calculated mortality prediction cut-points for the scores, the sensitivities and specificities were respectively 87% and 68% for TRISS, 81% and 61% for ISS, RTS yielded 81% and 60%, while for REMS it was 61% and 69%. The SI and RSI (cut-points used in agreement with the literature) produced sensitivities 58% and only 48%, and specificities of 73% and 83%, respectively.

45(41,7%) patients required ICU admission. Though the ICU LOS best correlated with ISS(r = 0.2710), the ICU LOS correlation coefficient was weak for all trauma scores. None of the scores had a significant p value for hospital LOS.

Discussion

Among the scores compared, TRISS had the highest sensitivity and NPV for mortality prediction in this South African polytrauma population. ISS correlated best with ICU LOS. However, compared to developed countries, ROC analyses & predictability of these scores fare relatively worse, and no correlation was found with hospital LOS. Therefore, we conclude that further studies are needed to ascertain a more suitable system for resource-limited settings.

[Quantitative and qualitative analysis of the influence of confinement by COVID-19 in fracture patients entered in a traumatology service at a third level hospital]

Introducción

La pandemia por COVID-19 ha supuesto el confinamiento de aproximadamente un tercio de la población mundial, provocando un cambio drástico en las actividades de la vida diaria con enorme impacto sanitario, económico y social.

Objetivos

El objetivo de este trabajo es presentar las variaciones epidemiológicas en la producción de fracturas en el período de confinamiento obligatorio en nuestra población de referencia.

Material y métodos

Estudio analítico retrospectivo comparativo de dos grupos de pacientes: Grupo A: personas ingresadas antes del estado de alarma que obligó al confinamiento en el período del 13 enero al 13 de marzo vs. Grupo B: individuos atendidos durante los dos meses de confinamiento, hasta que comenzó la desescalada, período del 13 marzo al 13 mayo. Se registraron variables epidemiológicas, incluyendo edad, antecedentes personales, tipo de fractura, mecanismo de lesión, porcentaje de ambulatorización y estancia hospitalaria.

Resultados

Se incluyeron un total de 190 pacientes. En el período de pre-confinamiento 112 y en el confinamiento 78 (disminución del 30%). La edad media (p = 0,007) y las caídas en domicilio (p<0,001) fueron mayores en este último grupo. La estancia hospitalaria postoperatoria (p = 0,006) y global (p < 0,001) resultaron significativamente menores en el mismo grupo. No se encontraron diferencias en la localización anatómica de la lesión, el sexo, las comorbilidades, el mecanismo de lesión, la tasa de ambulatorización ni el éxitus.

Conclusiones

Con base en los resultados de nuestro estudio, el período de confinamiento forzoso por la pandemia de COVID-19 ha producido una drástica disminución del número total de fracturas ingresadas en el servicio de traumatología de un hospital de tercer nivel. Por otro lado, las fracturas osteoporóticas de cadera que requirieron tratamiento quirúrgico no variaron en número y se ha constatado un decremento de la estancia media postoperatoria y global.

Accuracy of free-hand positioned patient specific implants (PSI) in primary reconstruction after inferior and/or medial orbital wall fractures

BACKGROUND

To assess the accuracy with which CAD/CAM-fabricated patient-specific titanium implants (PSI) are positioned for inferior and/or medial orbital wall reconstruction without the use of intraoperative navigation.

METHODS

Patients who underwent a primary reconstruction of the orbital walls with PSI due to fractures were enrolled in this retrospective cohort analysis. The primary outcome variables were the mean surface distances (MSD) between virtually planned and postoperative PSI position and single linear deviations in the x-, y- and z-axis at corresponding reference points. Secondary outcome variables included demographic data, classification of orbital wall defects and clinical outcomes.

RESULTS

A total of 33 PSI (orbital floor n = 22; medial wall, n = 11) were examined in 27 patients. MSD was on a comparable level for the orbital floor and medial wall (median 0.39 mm, range 0.22-1.53 mm vs. median 0.42 mm, range 0.21-0.98 mm; p = 0.56). Single linear deviations were lower for reconstructions of the orbital floor compared to the medial wall (median 0.45 vs. 0.79 mm; p < 0.05). There was no association between the occurrence of diplopia and the accuracy level (p = 0.418).

CONCLUSIONS

Free-hand positioning of PSI reaches a clinically appropriate level of accuracy, limiting the necessity of navigational systems to selected cases.

Ankle CT scan allows better management of posterior malleolus fractures than X-rays

PURPOSE

Undiagnosed and undertreated posterior malleolus fractures lead to early ankle instability and arthritis. A preoperative CT scan could improve the management of those fractures. This study assessed the benefits of a systematic ankle CT scanner to diagnose and manage posterior malleolus fracture.

METHODS

A monocentric retrospective cohort study was conducted. Sixty consecutive patients with bimalleolar fractures were operated and underwent a preoperative CT scan. The mean age was 50.0 years old (18.6 years old) with a mean body mass index of 20.3 (kg/m²) (11.4 kg/m²) and 71.7% (43/60) of women. The primary outcome was the rate of posterior malleolus fragment diagnosed on X-rays and on CT scan. Secondly, interobserver and interobserver's agreement were compared between conventional X-rays and CT scan.

RESULTS

Thirty-five (58.3%) posterior fragment fractures were observed on X-rays and 53 (88.3%) on the preoperative CT scan (p < 0.01). The intraobserver reproducibility for X-rays was low (0.02 [- 0.23; 0.27]) and moderate for CT scan (0.45 [0.0; 0.84]). The interobserver reproducibility for X-rays was moderate (0.39 [0.15; 0.60]) and excellent for CT scan (0.78 [0.0; 1.0]).

CONCLUSION

A wide proportion of bimalleolar fractures are associated with posterior malleolus fractures and undiagnosed with standard X-rays. We advocate a systematic preoperative CT scan in the management of bimalleolar fractures.

Has 2020 been a lost year in orthopedic surgery and trauma training? Residents' perceptions

OBJECTIVE

The COVID-19 pandemic has affected specialized healthcare training at all levels. Surgical learning has been severely affected, and the impact on orthopedic surgery residency training has so far not been assessed.

MATERIAL AND METHODS

An online survey of 17 questions was sent via web link to orthopedic surgery residents throughout Spain between February 10, 2021 and February 28, 2021. The effects of the COVID-19 pandemic on the care and training activities of residents were analyzed.

RESULTS

A total of 307 orthopedic surgery residents from all over Spain responded to the online survey. A total of 77.2% of the respondents had to suspend their rotations. Of these, 67.5% would like to resume the rotations they missed during the pandemic. A total of 69.7% of scheduled surgeries were suspended. Surgical activity was completely stopped for an average of 8 weeks. 66.8% of the residents consider that their surgical training has been affected and this will have repercussions on their future work. 49.5% considered the online training offered to be insufficient. Of the total number of respondents, 52.1% considered that the impact of the pandemic situation on their training situation was bad or very bad.

CONCLUSIONS

The data collection shows a negative impact on both theoretical and clinical training. This study highlights the need to continue offering quality training by maximizing learning opportunities.

Temporomandibular joint trauma and disability assessment - A longitudinal exploratory study

BACKGROUND

Orofacial trauma can encompass, isolated or not, several anatomical regions, namely facial, dental and temporomandibular joint (TMJ), one of the most complex joints in the human body. Evidence-based knowledge in the field of TMJ trauma and in temporomandibular joint disorders (TMD) diagnosis and treatment, provides the necessary data for medico-legal assessment.

OBJECTIVE

The aim of this study is to bring up epidemiological data referring to TMJ injuries and sequelae, in order to present a medico-legal approach of TMJ disability.

METHODS

An observational longitudinal exploratory study was performed in the database of the National Institute of Legal Medicine and Forensic Sciences, Portugal, between 2000 and 2017, regarding inclusion and exclusion criteria.Statistical significance was set as P‹0.05, Fisher's exact test, Binomial test and Goodman and Kruskal's test were used.

RESULTS

Post-traumatic orofacial reports (n = 2622) included 234 TMJ-injury and 149 TMJ-sequelae.Epidemiological data was presented regarding age,gender, professional status and etiology. There was a statistically significant association between TMJ injury and TMJ sequela, despite a weak relation (ƛ = 0.170). No statistically significant association was identified between TMJ-injury/TMJ-sequelae and the professional status, etiology.

CONCLUSION

The TMJ sequela group is smaller than the TMJ-injury, reflecting that 2/3 of the injuries have been cured without a monetary compensation value and without Health costs. The association between TMJ injury and TMJ sequelae reinforces the necessity of preventive measures in TMJ trauma, namely in physical violence context and in medico-legal impairment.

The future of basic science in orthopaedics and traumatology: Cassandra or Prometheus?

Orthopaedic and trauma research is a gateway to better health and mobility, reflecting the ever-increasing and complex burden of musculoskeletal diseases and injuries in Germany, Europe and worldwide. Basic science in orthopaedics and traumatology addresses the complete organism down to the molecule among an entire life of musculoskeletal mobility. Reflecting the complex and intertwined underlying mechanisms, cooperative research in this field has discovered important mechanisms on the molecular, cellular and organ levels, which subsequently led to innovative diagnostic and therapeutic strategies that reduced individual suffering as well as the burden on the society. However, research efforts are considerably threatened by economical pressures on clinicians and scientists, growing obstacles for urgently needed translational animal research, and insufficient funding. Although sophisticated science is feasible and realized in ever more individual research groups, a main goal of the multidisciplinary members of the Basic Science Section of the German Society for Orthopaedics and Trauma Surgery is to generate overarching structures and networks to answer to the growing clinical needs. The future of basic science in orthopaedics and traumatology can only be managed by an even more intensified exchange between basic scientists and clinicians while fuelling enthusiasm of talented junior scientists and clinicians. Prioritized future projects will master a broad range of opportunities from artificial intelligence, gene- and nano-technologies to large-scale, multi-centre clinical studies. Like Prometheus in the ancient Greek myth, transferring the elucidating knowledge from basic science to the real (clinical) world will reduce the individual suffering from orthopaedic diseases and trauma as well as their socio-economic impact.

Sexual Function Outcomes After Surgical Treatment of Penile Fracture

Introduction

Penile fracture is a urologic emergency and is defined as the rupture of the tunica albuginea of the cavernous body in erection.

Aim

Our study aims to evaluate patients with penile fracture and to identify the factors that may influence the sexual function after surgical repair.

Methods

A total of 138 patients who were diagnosed with penile fracture between January, 1999 and December, 2018 were reviewed. Clinical features, perioperative assessment, time from injury to surgery, tunica defect properties, and presence of urethral injury were assessed.

Main Outcome Measures

Sexual function was evaluated by three parameters six months after surgical repair: International Index of Erectile Function-5 (IIEF-5) questionnaire, penile curvature and the presence of a painful intercourse. All factors that could potentially influence these parameters were analyzed.

Results

The mean age was 31.2 years (19-55). Presentation delay ranged from 1 to 5 days (mean = 16.8 hours) while surgery delay was 14.3 hours ().The most common cause of penile fracture in our patients was forcefully bending of the erect penis to achieve detumescence in 62 cases (44.9%). On multivariate analysis, we found that the presentation delay and the fracture site located in the proximal shaft of the penis showed significant difference in the occurrence of postoperative ED (P = 0.03 and P = 0.015 respectively). Presentation delay, elective incision and tuncial leak located in the proximal shaft (P = 0.045; P = 0.018 and P = 0.022 respectively) were associated with higher penis curvature.

Conclusion

Immediate surgical repair and circumferential degloving incision for tunical leaks located in the proximal shaft of the penis are recommended in order to decrease the incidence of ED after surgical repair of penile fractures.

Quantitative and qualitative analysis of the influence of confinement by COVID-19 in fracture patients entered in a traumatology service at a third level hospital

Introduction

The COVID-19 pandemic has led to the confinement of approximately one third of the world population, causing a drastic change in the activities of daily life with many repercussions at the health, economic and social levels.

Objectives

The objective of the present work is to present the epidemiological variations in the production of fractures in the period of mandatory confinement in our reference population.

Methods

Analytical retrospective comparative study of two groups of patients: Group A: patients admitted before the state of alarm that forced confinement in the period from January 13 to March 13 compared to Group B: patients admitted in the two months of confinement, until the de-escalation period began, March 13-May 13. Epidemiological variables including age, personal history, type of fracture, mechanism of injury, outpatient rate, and hospital stay were recorded.

Results

A total of 190 patients were included. 112 in the pre-confinement period and 78 in the confinement (30% decrease). The mean age (p = 0.007) and falls at home (p < 0.001) were higher in the confinement group. The postoperative (p = 0.006) and overall (p < 0.001) hospital stay were significantly less in the confinement group. No differences were found in the anatomical location of the lesion, sex, comorbidities, mechanism of injury, outpatient rate, or death.

Conclusions

Based on the results of our study, the period of forced confinement due to the COVID-19 pandemic has produced a drastic decrease in the total number of fractures admitted to the traumatology service of a third level hospital. On the other hand, osteoporotic hip fractures have not varied in their incidence and a decrease in the average postoperative and overall stay has been observed.

[Urological emergency management : Detection and treatment]

As a result of the restructuring of emergency care provided by statutory health insurance companies and demographic change, the number of people presenting to emergency departments in hospitals is continuously increasing. A significant proportion of these emergencies concern the specialist discipline of urology. The clinical manifestations in emergency medical care range from trauma-related injuries to the urogenital tract and urinary transport disorders to hematuria and life-threatening infections. Due to the high incidence of urological tumors and the urogenital tract's affection in other malignant diseases, oncological patients are also frequently affected by urological emergencies. Fast and efficient diagnostic and therapeutic action is crucial in these situations to achieve an optimal treatment result.

Impact of lockdown during the COVID-19 pandemic on number of patients and patterns of injuries at a level I trauma center

OBJECTIVE

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) and its associated illness, coronavirus disease 2019 (COVID-19), has led to a global health crisis burdening frontline emergency departments, including orthopedic and trauma units. The aim of this study was to provide an overview of the impact of the lockdown secondary to the pandemic on patient numbers and pattern of injuries at the department of traumatology of the Medical University of Vienna.

METHODS

This retrospective, descriptive study identified all patients admitted and enrolled onto the trauma registry at a level I trauma center, between 15 March 2020 and 30 April 2020 (lockdown) and compared them to those between 15 March 2019 and 30 April 2019 (baseline). Variables collected included patient age, sex, reason for hospital admission, place of injury, death, injury severity score (ISS), as well as American Society of Anaesthesiologists (ASA) score.

RESULTS

A total of 10,938 patient visits to the trauma emergency department were analyzed, 8353 presentations during the baseline period and 2585 during lockdown. Only 1869 acutely injured and 716 follow-up patients presented during lockdown, compared to 6178 and 2175, respectively, during baseline. Throughout the COVID-19 lockdown there were significant reductions in both workplace and traffic accidents, sports injuries, number of hospitalized patients, and overall visits to the trauma emergency department; however, the number of major traumas and hip fractures remained similar. Furthermore, there was a significant increase in the frequency of injuries at home as well as hospital admissions due to attempted suicide.

CONCLUSION

Despite the reduction in total number of patients, trauma departments should continue to provide adequate service during lockdown considering that severe injuries showed no change. Conditions such as breakdown of social networks and limited access to mental health care and support might account for the significant rise in hospital admissions due to suicides. We recommend that more attention and effort should be made to prevent this excess of suicide deaths.
