Scoping an interdisciplinary model of student dental therapists in maxillofacial trauma.

Introduction This paper outlines a short pilot programme to assess the feasibility of an interdisciplinary model of involving student dental therapists in the management of maxillofacial trauma patients. It involved dental therapy students attending an oral and maxillofacial surgery trauma review clinic at a major trauma hospital in London, UK.Approach The small cohort of 15 second-year dental hygiene and therapy (BSc in Oral Health) students attended the trauma clinic once a week in pairs, over a period of six weeks, after which they completed a survey questionnaire.Findings No students had previous experience of dealing with trauma patients. The majority (81.8%) had learnt something by attending the clinic. Almost all (91.7%) had not thought previously about the importance of oral hygiene in maxillofacial trauma patients. By the end of the pilot programme, ten students (83.3%) felt that they had a role to play in the care of these trauma patients and they felt valued as members of the wider team.Conclusion These initial findings suggest that the scheme has potential for incorporation of maxillofacial trauma experience within the formal dental therapy curriculum. This would prepare them for future involvement in the management of maxillofacial trauma patients to promote oral health benefits and more widely, to work as a team member in interprofessional health care.

Features and networks of the mandible on computed tomography.

The mandible or lower jaw is the largest and hardest bone in the human facial skeleton. Fractures of the mandible are reported to be a common facial trauma in emergency medicine and gaining insights into mandibular morphology in different facial types can be helpful for trauma treatment. Furthermore, features of the mandible play an important role in forensics and anthropology for identifying gender and individuals. Thus, discovering hidden information of the mandible can benefit interdisciplinary research. Here, for the first time, a method of artificial intelligence-based nonlinear dynamics and network analysis are used for discovering dissimilar and similar radiographic features of mandibles between male and female subjects. Using a public dataset of 10 computed tomography scans of mandibles, the results suggest a difference in the distribution of spatial autocorrelation between genders, uniqueness in network topologies among individuals and shared values in recurrence quantification.

Diagnosis of pathological speech with streamlined features for long short-term memory learning.

BACKGROUND: Pathological speech diagnosis is crucial for identifying and treating various speech disorders. Accurate diagnosis aids in developing targeted intervention strategies, improving patients' communication abilities, and enhancing their overall quality of life. With the rising incidence of speech-related conditions globally, including oral health, the need for efficient and reliable diagnostic tools has become paramount, emphasizing the significance of advanced research in this field. METHODS: This paper introduces novel features for deep learning in the analysis of short voice signals. It proposes the incorporation of time-space and time-frequency features to accurately discern between two distinct groups: Individuals exhibiting normal vocal patterns and those manifesting pathological voice conditions. These advancements aim to enhance the precision and reliability of diagnostic procedures, paving the way for more targeted treatment approaches. RESULTS: Utilizing a publicly available voice database, this study carried out training and validation using long short-term memory (LSTM) networks learning on the combined features, along with a data balancing strategy. The proposed approach yielded promising performance metrics: 90% accuracy, 93% sensitivity, 87% specificity, 88% precision, an F1 score of 0.90, and an area under the receiver operating characteristic curve of 0.96. The results surpassed those obtained by the networks trained using wavelet-time scattering coefficients, as well as several algorithms trained with alternative feature types. CONCLUSIONS: The incorporation of time-frequency and time-space features extracted from short segments of voice signals for LSTM learning demonstrates significant promise as an AI tool for the diagnosis of speech pathology. The proposed approach has the potential to enhance the accuracy and allow for real-time pathological speech assessment, thereby facilitating more targeted and effective therapeutic interventions.

How good is good enough? Lessons learned from review of outcomes of 50 patients following extraoral open reduction and internal fixation of condylar neck and base fractures at a regional major trauma centre.

The management of mandibular fractures is routine owing to their frequency, particularly those of the mandibular condyle, which are invariably common. Notwithstanding disparities in the literature, the international consensus towards which fractures of the mandibular condyle benefit from open surgical intervention is almost universally accepted. Closed reduction or non-operative management may be utilised in certain circumstances. Whilst outcome research has addressed complications with respect to operative side effects, outcomes related to the quality of bone repair and the setting in which this is delivered have not been universally addressed. The aim of this study was to determine the predictability of translating an indicated operative treatment plan into an acceptable functional result. We evaluated the outcomes of 59 extracapsular condylar fractures in 50 patients who were treated by extraoral open reduction and internal fixation (ORIF) between March 2021 and August 2022. We reviewed demographic data, surgical approach, and plating strategy, and critically evaluated the clinical and radiological outcomes. Whilst we found that the quality of reduction was not universally perfect, the majority were within tolerance, which we set according to the Strasbourg Osteosynthesis Research Group (SORG) definition for minimal displacement (<2 mm overlap and 10° angulation). The cohort had good functional occlusion and minimal long-term postoperative complications. Two patients required re-operation for non-union, and we discuss causality in these cases. In conclusion, we found that ORIF of condylar neck and base fractures is predictable in real-time surgical practice with respect to functional outcome. However, if imperfectly reduced, there is a small risk of non-union.

Synthesis of Novel Antimicrobial CHX-CaCl2 Coatings on Maxillofacial Fixatures for Infection Prevention.

Maxillofacial surgery placement of fixatures (Leonard Buttons, LB) at close proximity to surgical incisions provides a potential reservoir as a secondary local factor to advanced periodontal disease, with bacterial formation around failed fixatures implicating plaque. To address infection rates, we aimed to surface coat LB and Titanium (Ti) discs using a novel form of chlorhexidine (CHX), CHX-CaCl2 and 0.2% CHX digluconate mouthwash as a comparison. CHX-CaCl2 coated, double-coated and mouthwash coated LB and Ti discs were transferred to 1 mL artificial saliva (AS) at specified time points, and UV-Visible spectroscopy (254 nm) was used to measure CHX release. The zone of inhibition (ZOI) was measured using collected aliquots against bacterial strains. Specimens were characterized using Energy Dispersive X-ray Spectroscopy (EDS), X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). SEM displayed copious dendritic crystals on LB/ Ti disc surfaces. Drug release from double-coated CHX-CaCl2 was 14 days (Ti discs) and 6 days (LB) above MIC, compared to the comparison group (20 min). The ZOI for the CHX-CaCl2 coated groups was significantly different within groups (p < 0.05). CHX-CaCl2 surface crystallization is a new drug technology for controlled and sustained CHX release; its antibacterial effectiveness makes this drug an ideal adjunct following clinical and surgical procedures to maintain oral hygiene and prevent surgical site infections.

Quantitative analysis of diplopia following orbital fracture repair.

Orbital fractures can result in devastating functional complications to sight and well-being, yet our understanding of functional sequelae post reconstruction is not well understood in the literature. This research retrospectively analysed the activity of a specialist orbital surgeon over five years to evaluate the incidence of, and risk factors for, debilitating complications such as diplopia and restriction of extraocular movement. Orbital fracture cases repaired between 1 January 2015 and 31 December 2019 were retrospectively analysed. Demographics, orthoptic assessment, injury classification, timing, operative details, outcomes, and complications were recorded. Preoperative and postoperative binocular single vision scores (BSV) were recorded to calculate the effect of orbital repair on residual diplopia. Of 582 patients undergoing orbital access, 472 cases of orbital wall reconstruction satisfied the inclusion criteria, of which 162 (34%) were Jaquiéry 4 or 5. Overall, 10.6% had complications, 4.9% had diplopia, and 5.7% were returned to theatre. All those with residual diplopia had had it preoperatively, and had evidence of an improvement in BSV score. Time to surgery, material, and pure orbital fractures had a significant impact on the incidence of diplopia. Defect size did not. Whilst complication rates were low we conclude that strict adherence to a defined surgical protocol, postoperative imaging, and objective assessment of postoperative function are central to maintaining these standards. Objective orthoptic analysis of patients before and after orbital repair is critical to our understanding of this pathology. Whilst preoperative prediction of the persistence of long-term diplopia currently eludes us, further research should target it.

A review on artificial intelligence for the diagnosis of fractures in facial trauma imaging.

Patients with facial trauma may suffer from injuries such as broken bones, bleeding, swelling, bruising, lacerations, burns, and deformity in the face. Common causes of facial-bone fractures are the results of road accidents, violence, and sports injuries. Surgery is needed if the trauma patient would be deprived of normal functioning or subject to facial deformity based on findings from radiology. Although the image reading by radiologists is useful for evaluating suspected facial fractures, there are certain challenges in human-based diagnostics. Artificial intelligence (AI) is making a quantum leap in radiology, producing significant improvements of reports and workflows. Here, an updated literature review is presented on the impact of AI in facial trauma with a special reference to fracture detection in radiology. The purpose is to gain insights into the current development and demand for future research in facial trauma. This review also discusses limitations to be overcome and current important issues for investigation in order to make AI applications to the trauma more effective and realistic in practical settings. The publications selected for review were based on their clinical significance, journal metrics, and journal indexing.

Can an App-Based Maxillofacial Trauma Score Predict the Operative Time, ICU Need and Length of Stay?

Study Design: Retrospective chart review. Objective: Injury and trauma scores are the mainstay of predicting outcomes of trauma patients. ZS (Zeeshan and Simon) maxillofacial trauma score is based on 4 previous facial trauma scores and is user friendly, app-based visually coded facial trauma scoring system. Our study was designed to seek the application of an app-based ZS maxillofacial trauma score to predict the operative time, intensive care unit (ICU) need and length of stay. Methods: We performed a retrospective chart review of patients who presented to a university medical college teaching hospital with maxillofacial fractures from October 2018 until October 2019. ZS maxillofacial trauma scoring app was used to calculate the ZS maxillofacial trauma severity score, which was our primary predictor variable. Our primary outcome of interest was operative time. Our secondary outcome of interest was ICU need and length of stay. Correlation analysis, linear regression and logistic regression were performed for statistical analysis. A statistical P-value of .05 was considered significant at a 95% confidence interval. Results: There were 95 male and 5 female patients included in the study. The age ranged from 3 to 84 years with a mean of 30.76 (SD = 14.04). A statistically significant correlation between the ZS score and operative time (r = 0.67, P < .001) was observed. ZS score predicted operative time (b 1 = 7.67, P < .001) in our study sample. Increasing ZS trauma score was also significantly associated with ICU requirement (X 2 (3) = 13.682, P = .003), but the length of stay could not be predicted based on ZS score.Conclusions: ZS maxillofacial trauma score can predict the operative time, and an association was seen with the need for ICU with increasing ZS score, but could not predict the length of stay or the ICU need. It has potential for future integration with electronic health record systems.

Mathematical analysis of fracture configuration in predicting outcome in complex anterior skull base trauma.

Craniofacial trauma involving the anterior skull base produces a heterogenous injury with variance in fracture pattern, complexity and outcome. Variance is influenced by the biomechanical properties of the craniofacial construct and by the magnitude and vector of the impacting energy. Fractal dimension and other metrics applied to individual fracture patterns allows quantification of fracture complexity and severity, which can be used to correlate with neurological outcome. Frontobasal fractures from 81 patients admitted to two UK major trauma centres were analysed. Patients were divided into two groups: those with anteriorly-based vectors of impact and those with laterally-based vectors. Osseous disruption was quantified by: fractal dimension, fracture length, number of termini, and number of nodes, and then compared with neurological outcome using first recorded Glasgow Coma Score (GCS), and requirement for intubation. As fracture length increased, fractures from anterior impacts became more complex and reticulated compared with lateral impacts; fractal dimension also increased more rapidly for anterior impacts. Longer fracture length in both groups was associated with a significantly lower GCS, and increased requirement for intubation (p < 0.001 and p < 0.001 respectively). Fracture propagation and severity of head injury was different in anterior-directed trauma compared to lateral-directed trauma. Consequently, we suggest that the central region of the anterior skull base acts to primarily absorb impact force thereby behaving as a protective ' crumple zone ' . In severe mechanisms the protective mechanism is exceeded and the fracture length tended to that of the lateral group worsening prognosis.

Orbital Bone Fractures in a Central London Trauma Center: A Retrospective Study of 582 Patients.

ABSTRACT: The aim of the present study was to evaluate the injury patterns and etiology of orbital bone fractures treated at a busy level one trauma center.Between 2015 and 2019, patients with orbital bone fractures from the Department of Oral and Maxillofacial Surgery at the Royal London Hospital, were evaluated in a retrospective analysis. A pro-forma was used to collect data from electronic patient records. Parameters included age, gender, maxillofacial fracture, mechanism of injury, and length of hospital admission.Of 582 patients, 82% (n = 476) were male and 18% (n = 106) were female, with those in the age group 20 to 29 years most affected (36%; n = 212). The most common etiology was interpersonal violence (55%; n = 320), followed by falls (20%; n = 118) and road traffic accidents (12%, n = 68). The most common isolated orbital bone fracture site was the orbital floor (40%; n = 234). Of the impure orbital fractures, the zygoma was the most commonly involved structure adjacent to the orbit (19%, n = 110).In our department, the authors see high numbers of complex orbital bone requiring surgical treatment. Interpersonal violence is a significant cause of orbital bone fractures with young males most affected. This study provides an insight into the current trends in etiology, demographics, and clinical findings of orbital fractures that will help guide prevention and treatment strategies.

Acquired Brown Syndrome in Head Trauma: Does Fixation of Associated Nasal and Frontal Bone Fractures Provide a Cure?

A 43-year-old gentleman presented with vertical double vision following nasal and frontal bone fractures resulting from blunt trauma to the glabella. Orthoptic assessment revealed a diagnosis of traumatic Brown syndrome affecting the right eye. The fractures were fixed with open reduction internal fixation via a coronal flap nine days after the injury was sustained. Evidence of resolution of the syndrome became apparent clinically within 15 days following surgery, which was confirmed with a later orthoptic evaluation. This case demonstrates that prompt surgical intervention of fractures associated with traumatic Brown syndrome may lead to resolution without the need to resort to extraocular muscle surgery.

Elite and Professional sports facial injuries management - a consensus report.

Whilst there have been great improvements in the management of elite and professional athletes with the formalisation of the clinical specialty of Sports and Exercise medicine, the management of facial injuries has perhaps lagged in this group. Professional athletic careers can be put in jeopardy due to unnecessarily long absences from training and competition after facial injuries. Professional and elite sports athletes can benefit from different approaches to the management of their facial injuries to reduce time away from competing but maximise their safety. On 6th December 2018, a consensus meeting of interested clinicians involved in the management of facial injuries of elite and professional athletes was held at the Royal Society of Medicine, London, UK to provide a contemporary review of the approaches to conservative, operative and recovery management of facial injuries. National experts with specialist experience of facial injuries presentation and athlete needs from a range of elite and professional sports led the day's programme and the discussions so that guidelines could be formulated. These are presented in this review paper.

Toward a consensus view in the management of acute facial injuries during the Covid-19 pandemic.

In these unprecedented times, OMFS surgeons are faced with dilemmas over the priority of treatment, safety of staff, safety of patients and the most appropriate use of available resources. Efforts should be made to provide the best evidence-based care, which will mean revisiting old techniques, and risk stratifying patients on a case by case basis. Recent experience from colleagues internationally has shown that even the wealthiest health care infrastructure is at best fragile. We hope this paper will add to the debate and hopefully provide a framework for decision making in OMFS trauma care during this difficult time.

Motor vehicle accidents-related maxillofacial injuries: a multicentre and prospective study.

OBJECTIVES: The purpose of this European multicenter prospective study was to obtain more precise information about the demographic characteristics and etiologic/epidemiologic patterns of motor vehicle accidents (MVA)-related maxillofacial fractures. STUDY DESIGN: Of the 3260 patients with maxillofacial fractures admitted within the study period, 326 traumas were caused by MVAs with a male/female ratio of 2.2:1. RESULTS: The maximum incidence was found in Zagreb (Croatia) (18%) and the minimum in Bergen (Norway) (0%). The most frequent mechanisms were car accidents, with 177 cases, followed by motorcycle accidents. The most frequently observed fracture involved the mandible, with 199 fractures, followed by maxillo-zygomatic-orbital (MZO) fractures. CONCLUSIONS: In all the 3 groups (car, motorcycle, and pedestrian), mandibular and MZO fractures were the 2 most frequently observed fractures, with some variations. The importance of analyzing MVA-related facial injuries and their features and characteristics should be stressed.

The "European zygomatic fracture" research project: The epidemiological results from a multicenter European collaboration.

PURPOSE: Fractures of the zygomaticomaxillary complex (ZMC) are common injuries that may lead to loss of an aesthetically pleasing appearance and functional impairment. The aim of this study was to analyze the demographics, causes, characteristics, and outcomes of zygomatic fractures managed at several European departments of oral and maxillofacial surgery. MATERIALS AND METHODS: This study is based on a multicenter systematic database that allowed the recording of all patients with ZMC fractures between 1 January 2013 and 31 December 2017. The following data were recorded: gender, age, personal medical history, etiology, side of zygomatic fracture, classification of ZMC fracture, associated maxillofacial fractures, symptoms at diagnosis, type of performed treatment, and sequelae/complications. RESULTS: A total of 1406 patients (1172 males, 234 females) were included in the study. Statistically significant correlations were found between assault-related ZMC fractures and the A3 class (p < .0000005) and between Infraorbital Nerve (ION) anesthesia and B class (p < .00000005). CONCLUSION: The most frequent cause of ZMC fractures was assault, followed by falls. The most frequently involved decade of age was between 20 and 29 years. The decision and type of surgical treatment of ZMC fractures depends on several issues that need to be considered on a case by case basis.

Prevalence and predictive factors of psychological morbidity following facial injury: a prospective study of patients attending a maxillofacial outpatient clinic within a major UK city.

Adults presenting to maxillofacial surgery services are at high risk of psychological morbidity. This study examined the prevalence of depression, post-traumatic stress disorder (PTSD), anxiety, drug and alcohol use, and appearance-related distress among maxillofacial trauma outpatients over medium-term follow-up. It also explored socio-demographic and injury-related variables associated with psychological distress to inform targeted psychological screening protocols for maxillofacial trauma services. Significant associations were found between level of distress at time of injury and number of traumatic life events with levels of depression at 3 months. No significant associations were found between predictor variables and PTSD at 3 months, or with any psychiatric diagnosis at 6 months. The lack of evidence for an identifiable subgroup of patients who were at higher risk of psychological distress indicated that routine screening of all maxillofacial trauma outpatients should be offered in order to best respond to their mental health needs. The feasibility of the medical team facilitating this is challenging and should ideally be undertaken by psychologists integrated within the MDT. This study led to the funding of a clinical psychologist to provide collaborative care with the maxillofacial surgeons, resulting in brief assessment and treatment to over 600 patients in the first year of the service.

Los adultos que consultan en los servicios de cirugía máxilo-facial tienen un alto riesgo de presentar morbilidad psicológica. Este estudio examinó la prevalencia de depresión, trastorno por estrés postraumático (TEPT), ansiedad, uso de alcohol y drogas, y distrés relacionado con la apariencia entre los pacientes con trauma máxilofacial en un seguimiento ambulatorio de mediano plazo. También se exploraron variables socio-demográficas y otras relacionadas con las lesiones que se asocian con distrés psicológico para contar con protocolos de evaluación psicológica orientados a los servicios de trauma máxilo-facial. Se encontraron asociaciones significativas entre el nivel de distrés al momento de la lesión y el número de acontecimientos traumáticos con los niveles de depresión a los tres meses. En cambio, no hubo asociaciones significativas entre las variables predictoras y el TEPT a los tres meses, o con algún diagnóstico psiquiátrico a los seis meses. La falta de evidencia de un subgrupo identificable de pacientes que estuvieron en alto riesgo de distrés psicológico indicaron que se debe ofrecer la evaluación de rutina a todos los pacientes ambulatorios con trauma máxilo-facial para responder mejor a sus necesidades de salud mental. Constituye un desafío configurar un equipo médico que permita esto y lo ideal es que se forme un equipo multidisciplinario en que estén integrados psicólogos. Este estudio permitió el financiamiento de un psicólogo clínico, quien aportó atención en colaboración con los cirujanos máxilo-faciales, lo que se tradujo en una evaluación breve y el tratamiento de más de 600 pacientes durante el primer año de funcionamiento del servicio.

Les adultes hospitalisés des services de chirurgie maxillo-faciale sont à risque élevé de morbidité psychologique. Cette étude analyse la prévalence de la dépression, du syndrome de stress post-traumatique (SSPT), de l'anxiété, de la consommation de drogues et d'alcool ainsi que de la détresse liée à l'apparence chez des patients ayant subi un traumatisme maxillo-facial, avec un suivi à moyen terme en ambulatoire. Les variables socio-démographiques et liées à la lésion ainsi que la détresse psychologique sont également examinées afin de renseigner des protocoles ciblés de dépistage psychologique pour les services de chirurgie maxillo-faciale. Le niveau de détresse au moment de la lésion et le nombre d'événements traumatiques de la vie sont significativement associés aux niveaux de dépression à 3 mois. Aucune association significative n'a été trouvée entre les variables prédictives et le SSPT à 3 mois ou un diagnostic psychiatrique quel qu'il soit à 6 mois. L'identification d'un sous-groupe de patients à risque élevé de détresse psychologique est difficile : le dépistage de routine de tous les patients suivis en ambulatoire après chirurgie maxillo-faciale devrait donc être proposé afin de mieux répondre à leurs besoins en santé mentale. Créer l'équipe médicale qui le permettrait est compliqué ; idéalement, cette tâche devrait être confiée à des psychologues au sein d'une équipe pluridisciplinaire. Grâce à l'étude, le poste d'un psychologue clinicien a été financé, qui travaille en collaboration avec les chirurgiens maxillo-faciaux. C'est ainsi que plus de 600 patients ont été évalués et traités au cours de la première année.

The 100 Most Cited Articles in Facial Trauma: A Bibliometric Analysis.

PURPOSE: The number of citations an article receives has been used as a marker of its influence within a surgical specialty. Currently, there is limited citation analysis in oral and maxillofacial trauma surgery. The purpose of this study was to determine the 100 most cited articles in facial trauma surgery and their characteristics. MATERIALS AND METHODS: Articles were identified from the Science Citation Index of the Institute for Scientific Information using the Thomson Reuters Web of Science search engine. All articles until 2015 were included. Then, the 100 most cited articles were assessed for title, author, journal, country of origin, and number of citations. A citation index (number of citations received per year) also was calculated. RESULTS: The 100 most cited articles in facial trauma received 9,933 citations (range, 66 to 297). They were published from 1942 through 2008, with 1990 through 1999 being the commonest decade. Articles were cited on average 4.6 times per year. Articles were published in 28 different journals, with impact factors ranging from 0.94 to 35.3. Most articles were observational research studies. CONCLUSION: These findings reflect the attention that articles have received during the past half century in oral and maxillofacial trauma research, shedding light on often-read articles in this field. In addition to current bibliometric indices, it could provide a useful evidence base for facial surgeons, represent key educational material for aspiring trainees, and be used to help guide future research efforts.

Good people who try their best can have problems: recognition of human factors and how to minimise error.

Human error is as old as humanity itself and is an appreciable cause of mistakes by both organisations and people. Much of the work related to human factors in causing error has originated from aviation where mistakes can be catastrophic not only for those who contribute to the error, but for passengers as well. The role of human error in medical and surgical incidents, which are often multifactorial, is becoming better understood, and includes both organisational issues (by the employer) and potential human factors (at a personal level). Mistakes as a result of individual human factors and surgical teams should be better recognised and emphasised. Attitudes and acceptance of preoperative briefing has improved since the introduction of the World Health Organization (WHO) surgical checklist. However, this does not address limitations or other safety concerns that are related to performance, such as stress and fatigue, emotional state, hunger, awareness of what is going on situational awareness, and other factors that could potentially lead to error. Here we attempt to raise awareness of these human factors, and highlight how they can lead to error, and how they can be minimised in our day-to-day practice. Can hospitals move from being "high risk industries" to "high reliability organisations"?

Assault-related maxillofacial injuries: the results from the European Maxillofacial Trauma (EURMAT) multicenter and prospective collaboration.

OBJECTIVE: The aim of this study is to present and discuss the demographic characteristics and patterns of assault-related maxillofacial fractures as reported by a European multicenter prospective study. STUDY DESIGN: Demographic and injury data were recorded for each patient who was a victim of an assault. RESULTS: Assaults represented the most frequent etiology of maxillofacial trauma with an overall rate of 39% and the values ranging between 60.8% (Kiev, Ukraine) and 15.4% (Bergen, Norway). The most frequent mechanisms of assault-related maxillofacial fractures were fists in 730 cases, followed by kicks and fists. The most frequently observed fracture involved the mandible (814 fractures), followed by orbito-zygomatic-maxillary complex fractures and orbital fractures. CONCLUSIONS: Our data confirmed the strong possibility that patients with maxillofacial fractures may be victims of physical aggression. The crucial role of alcohol in assault-related fractures was also confirmed by our study.
