Adding Injury to Insult: A National Analysis of Combat Sport-Related Facial Injury

Seeing through the strikes: a comprehensive study of ocular injuries in martial arts from 2012 to 2021

PURPOSE

Over 6 million people in the United States participate in martial arts, and the focus on striking the face poses a significant risk of injury to the eye. The objective of this study is to characterize the nature and incidence of martial arts-related eye injuries in the United States.

METHODS

A retrospective analysis of the National Electronic Injury Surveillance System (NEISS) database served as the basis of the study. The NEISS database was queried for eye injuries related to martial arts from 2012 to 2021. The entries that resulted were coded for demographic information, mechanism of injury, martial arts discipline, and diagnosis. Data were analyzed using SPSS version 28 through descriptive and χ2 analyses.

RESULTS

There were 162 reported cases of martial arts-related eye injuries in 4- to 62-years-old patients with most injuries occurring in males (84%). The most represented martial arts discipline was boxing (30.5%), and the most frequently reported mechanism of injury was punching (30.2%). The most frequently reported diagnosis resulting from eye injury was corneal abrasion (40.5%), while sight-threatening diagnoses were reported, including retinal detachment (n = 4), vitreous hemorrhage (n = 2), and open globe (n = 2).

CONCLUSIONS

Despite the significant risk of ocular injury from martial arts, corneal abrasion was the most commonly diagnosed with excellent prognosis. Sight-threatening diagnoses were also reported, indicating that martial arts athletes should be educated about the risks of eye injury and the importance of regular eye examination when practicing combat sports.

Headguard use in combat sports: position statement of the Association of Ringside Physicians

Headguard use is appropriate during some combat sports activities where the risks of injury to the face and ears are elevated. Headguards are highly effective in reducing the incidence of facial lacerations in studies of amateur boxers and are just as effective in other striking sports. They should be used in scenarios - especially sparring prior to competitions - where avoidance of laceration and subsequent exposure to potential blood-borne pathogens is important. Headguards are appropriate where avoidance of auricular injury is deemed important; limited data show a marked reduction in incidence of auricular injury in wrestlers wearing headguards.Headguards should not be relied upon to reduce the risk of concussion or other traumatic brain injury. They have not been shown to prevent these types of injuries in combat sports or other sports, and human studies on the effect of headguards on concussive injury are lacking. While biomechanical studies suggest they reduce linear and rotational acceleration of the cranium, changes in athlete behavior to more risk-taking when wearing headguards may offset any risk reduction. In the absence of high-quality studies on headguard use, the Association of Ringside Physicians recommends that further research be conducted to clarify the role of headguards in all combat sports, at all ages of participation. Furthermore, in the absence of data on gender differences, policies should be standardized for men and women.

Trends in mandibular fractures in the USA: A 20-year retrospective analysis

BACKGROUND/AIM

The mandible is one of the most fractured bones in the maxillofacial region. This study analyzes trends in mandibular fracture patterns, demographics, and mechanisms since the early 2000s.

MATERIAL AND METHODS

Mandibular fractures were reviewed from the 2007, 2011, and 2017 National Trauma Data Bank including 13,142, 17,057, and 20,391 patients by year, respectively. This database contains hundreds of thousands of patients annually and represents the largest trauma registry in the United States. Variables included number of fractures, sex, age, injury mechanism, and fracture location. Mechanism of injury included assault, motor vehicle crash, fall, motorcycle, bicycle, pedestrian, and firearm. Anatomic locations based on ICD-9/10 codes included symphysis, ramus, condyle, condylar process, body, angle, and coronoid process. Frequencies were compared using Chi-square tests of homogeneity with effect sizes estimated using Cramer's V.

RESULTS

Mandibular fractures represent 2%-2.5% of all traumas reported in the database from 2001 to 2017. The proportion of patients sustaining a single reported mandibular fracture decreased from 82% in 2007 to 63% in 2017. Males consistently experienced 78%-80% of fractures. Eighteen to 54-year-olds experienced the largest percentages of fractures throughout the 21st century, while median age of fracture shifted from 28 to 32 between 2007 and 2017. The most common fracture mechanisms were assault (42% [2001-2005]-37% [2017]), motor vehicle crash (31%-22%) followed by falls (15%-20%). From 2001-2005 to 2017, a decrease was observed in assaults (-5%) and motor vehicle crash (-9%) and an increase in falls (+5%), particularly among elderly females. The mandibular body, condyle, angle, and symphysis represent approximately two-thirds of all fractures without a consistent temporal trend among them.

CONCLUSIONS

The temporal trends observed can be linked to shifting age demographics nationally that may aid clinicians in diagnosis and inform public safety policies aimed at reducing these injuries, particularly among the growing elderly population.

Incidence Rates and Pathology Types of Boxing-Specific Injuries: A Systematic Review and Meta-analysis of Epidemiology Studies in the 21st Century

Background

To the best of our knowledge, an evidence-based investigation into 21st-century boxing-specific injury rates and types has yet to be performed.

Purpose

To provide an overview and quantitative synthesis of the incidence rates (IRs) and pathological categorizations of boxing-specific injuries in the 21st century.

Study Design

Systematic review; Level of evidence, 3.

Methods

Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched literature published from January 2000 to November 2021 in PubMed and the Cochrane Library systematically for qualifying epidemiology studies of organized boxing activities across the world. Two independent reviewers completed the literature review, data extraction, and quality assessment. The IRs of injuries per 1000 boxers (IR_N), per 1000 competition exposures (IR_E), and per 1000 minutes of competition (IR_C) or training (IR_T) were subsequently calculated. Single-arm meta-analyses were performed for the subgroups of different types of boxing. Sample size weighted means were calculated using a random-effects model in all studies with 95% CIs.

Results

Out of an initial 9584 articles, 14 studies were included, with most (11/14) having a moderate level of quality. The pooled IR_N in overall injuries was 223.9 (95% CI, 157.5-290.4), the IR_E was 233.3 (95% CI, 161.3-305.2), and the IR_C was 13.0 (95% CI, 8.9-17.1). In professional boxing, the IR_N (399.8), IR_E (379.8), and IR_C (23.9) were all significantly higher than in the amateur and female groups. The IR_E (76.6 vs 250.6; P < .000) and IR_C (9.2 vs 15.4; P < .000) in amateur boxing were significantly lower in studies between 2010 and 2019 than in earlier studies. For pathology categorization, the pooled frequencies were 12.3% (95% CI, 8.7%-15.9%) for concussion, 21.4% (95% CI, 14.1%-28.6%) for skin laceration, 30.2% (95% CI, 22.1%-38.2%) for soft tissue contusion, 15.3% (95% CI, 7.7%-22.9%) for sprain and muscle/ligament injury, and 11.4% (95% CI, 2.7%-20.1%) for fracture.

Conclusion

IRs of injury remain high in professional boxing, although they have decreased in the past 10 years in amateur boxing. Soft tissue contusion was the most common injury type. Better exposure measurements and epidemiologic indicators should be applied in future studies.

Characterization of the Epidemiology and Risk Factors for Hand Fractures in Patients Aged 1 to 19 Presenting to United States Emergency Departments: A Retrospective Study of 21,031 Cases

BACKGROUND

Hand fractures are among the most common injuries presenting in pediatric emergency departments (EDs) with incidence reported as high as 624 hand fractures per 100,000 person-years. If gone untreated, these injuries can lead to pain, loss of function, and psychological trauma. The purpose of this study was to identify risk factors and characterize pediatric hand fractures over a 5-year period.

METHODS

The National Electronic Injury Surveillance System (NEISS) was queried for all hand fractures in patients aged 1 to 19 years presenting to US EDs between 2016 and 2020. Incidence was calculated using US census data. Cases were retrospectively analyzed using age, location of the injury, sex, coronavirus disease-2019 (COVID-19) era, and etiology of injury. Bivariate logistic regression was used where appropriate.

RESULTS

A total of 21,031 pediatric hand fractures were identified, representing an estimated 565,833 pediatric hand fractures presenting to EDs between 2016 and 2020. The mean incidence of pediatric hand fractures was 138.3 fractures for 100,000 person-years [95% confidence interval (CI): 136.2-140.4], with a 39.2% decrease in incidence occurring between 2019 and 2020. It was found that 42.2% of the fractures were in patients aged 10 to 14. The incidence of hand fractures for males and females was 97.9 (95% CI: 96.2-99.7) and 40.4 (95% CI: 39.2-41.5), respectively, with the male rate peaking at age 14 and the female rate peaking at age 12. Age, sex, location of the injury, and injury during the COVID-19 pandemic were demonstrated to influence the frequency and etiology of the fracture.

CONCLUSION

This study determined the incidence of pediatric hand fractures presenting to EDs across the United States. In addition, it identified risk factors for common hand fracture etiologies (sports-related, falling, crush, punching) and demonstrated the change in rates of different etiologies of pediatric hand fractures that presented to US EDs during the COVID-19 pandemic.

LEVEL OF EVIDENCE

Level III-retrospective comparative study.

Characterization of Musculoskeletal Injuries in Gymnastics Participants From 2013 to 2020

BACKGROUND

Many studies have analyzed gymnastics-related injuries in collegiate and elite athletes, but there is minimal literature analyzing the epidemiological characteristics of injuries in the greater gymnastics community.

HYPOTHESIS

A higher incidence of injuries in younger gymnasts between the ages of 6 and 15 years compared with those 16 years and older and a difference in the distribution of injuries between male and female gymnasts.

STUDY DESIGN

Retrospective cross-sectional study.

LEVEL OF EVIDENCE

Level 3.

METHODS

The National Electronic Injury Surveillance System (NEISS) was queried for all gymnastics-related musculoskeletal injuries presenting to the emergency department (ED) between 2013 and 2020. Incidence was calculated as per 100,000 person-years using the weighted estimates provided by NEISS and national participation data. Chi-square and column proportion z-testing was used to analyze where appropriate.

RESULTS

The incidence of gymnastics-related musculoskeletal injuries was 480.7 per 100,000 person-years. Most ED visits were children between the ages of 6 and 15 years (84.0%). Younger gymnasts (ages 6 to 10) were most likely to experience a lower arm fracture, while those over the age of 10 years were most likely to experience an ankle sprain (P < 0.01). Men and boys presented with a much greater proportion of shoulder injuries (8.0% vs 3.9%), while women and girls presented with a greater proportion of elbow injuries (9.9 % vs 5.9%) and wrist (10.5% vs 8.3%) injuries (P < 0.01).

CONCLUSION

As hypothesized, most gymnastics-related injuries between 2013 and 2020 were athletes between 6 and 15 years old. Many of these athletes are attempting new, more difficult, skills and are at increased risk of more acute injury when attempting skills they may be unfamiliar with.

CLINICAL RELEVANCE

With increased pressure to specialize at an early age to maintain competitiveness and learn new, higher-level skills compared with their peers, younger athletes are most susceptible to acute injury. New injury prevention strategies could be implemented to help this high-risk population compete and train safely.

Children in Boxing and Martial Arts Should Be Better Guarded From Facial Injuries

STUDY DESIGN

Cross-sectional study.

OBJECTIVE

Childhood participation in boxing and martial arts has increased over the past decade, and these activities are well-known causes of traumatic injury. We hypothesized that the face is frequently injured in the setting of pediatric boxing and martial arts trauma in the United States and that there are identifiable injury patterns.

METHODS

We performed a cross-sectional study of consecutive pediatric patients in the National Electronic Injury Surveillance System (NEISS) from January 1, 2010 to December 31, 2019. Patients were included in our study if they were younger than 18 years of age and evaluated in the emergency department (ED) after boxing or martial arts trauma. Primary outcome was facial injury. Other variables of interest include age, sex, ED disposition, type and location of injury. Descriptive and univariate statistics of the primary outcome were computed with these variables.

RESULTS

There were 4,978 total pediatric patients injured due to boxing and martial arts trauma reported by NEISS-participating EDs during the study period, and 264 patients experienced injury to the face (264/4978; 5.3%). Over 20% (n = 60) of reported facial injuries were fractures; the most fractured structure was the nose (42/60; 70), orbit (11/60; 18.3%), and mandible (6/60; 10%). Almost 20% (11/60%) of pediatric facial fractures due to boxing and martial arts trauma involved fighting a family member or friend, and a punch was the most common mode of fracture (42/58; 72.4%).

CONCLUSIONS

Facial injuries comprise about 5% of injuries after boxing and martial arts trauma and 22% of these facial injuries are fractures. If children choose to participate, parents, coaches, trainers, officials, and community leaders should make the greatest effort possible to minimize risk, including the mandatory use of head and face protective gear and elimination of training fighting, or "sparring."

Trends in Lower Extremity Injuries Presenting to Emergency Departments During the COVID-19 Pandemic

Background

During the emergence of the SARS-CoV-2 (COVID-19) pandemic, there were substantial changes in U.S. emergency department (ED) volumes and acuity of patient presentation compared with more recent years. Objectives: The purpose of this study was to characterize the incidence of specific lower extremity (LE) injuries presenting to U.S. EDs during the COVID-19 pandemic and to analyze trends across age groups and rates of hospital admission compared with previous years.

Methods

The National Electronic Injury Surveillance System database was queried to identify patients who presented to U.S. EDs for a LE orthopedic injury between 2016 and 2020.

Results

These queries returned 252,656 cases, representing a total estimate of 9,740,514 injuries presenting to EDs across the United States. The mean incidence of LE orthopedic injuries was 596.8 injuries per 100,000 person-years (95% confidence interval [CI] 594.9–598.7), with the greatest annual decrease in incidence occurring between 2019 and 2020 (24.96%). The largest number of estimated hospital admissions occurred in 2020, with a total 181,671 admissions (95% CI 178,032–185,311), a 25.74% increase from the average number of admissions between 2016 and 2019.

Conclusion

The COVID-19 pandemic has placed immense stress on both emergency medical services and hospital systems around the United States. While there were decreased rates of ED utilization for LE orthopedic complaints during the first year of the pandemic, there was a concomitant increase in both the number and proportion of these injuries admitted to the hospital from the ED. This places an additional burden on already stressed emergency medicine services and overall hospital systems that could slow down the management of medical emergencies.

A Nationwide Epidemiological Analysis of Finger Infections Presenting to Emergency Departments in the United States From 2012 to 2016

Background: There is a paucity of literature exploring the epidemiology of finger infections presenting to emergency departments (EDs) on a national scale. The purpose of this study was to determine the national incidence of and risk factors for finger infections. Methods: Finger infections presenting to EDs between 2012 and 2016 were identified in the National Electronic Injury Surveillance System database. Finger infections were characterized by mechanism and type, with subanalyses for sex, race, and age. Results: Over this 5-year period, finger infections accounted for 80 519 visits to EDs in the United States. The annual incidence increased significantly from 4.4 per 100 000 person-years in 2012 to 6.2 in 2016. The 3 most common causes of finger infections were nail manicuring tools, knives, and doors. The most common diagnosis was finger cellulitis (46.3%). Significantly more men developed finger infections than women (relative risk of 1.4). The highest overall incidence was observed in 40- to 59-year-old men (7.8 per 100 000 person-years). Tenosynovitis resulted in the largest proportion of admissions (25%). Conclusions: We have demonstrated a rising incidence of finger infections presenting to EDs, with 40- to 59-year-old patients most at risk. The most common mechanism was the use of nail manicuring tools, such as nail clippers. Patient education may decrease finger infection incidence from these activities, and early detection of finger infections may be crucial to minimizing hospital admissions and invasive treatments.

Craniomaxillofacial injuries from the sport of wrestling: a query of the National Electronic Injury Surveillance System (NEISS)

PURPOSE

The purpose of this study was to provide a novel report on the head and neck injuries from the sport of wrestling and their characteristics in the USA.

MATERIALS AND METHODS

This is a 20-year retrospective cross-sectional study conducted using the National Electronic Injury Surveillance System (NEISS). Reports were included in the analysis if the injury stemmed from combat with another person. The predictor variables were obtained from both patient and injury characteristics. The principal outcome variable was admission rate, which was used to proxy the severity of the injury at hand. Bivariate analysis (i.e., chi-square and independent sample tests) was used to determine if an association existed between two variables of interest.

RESULTS

The final sample in our study consisted of 4485 cases of craniomaxillofacial injuries secondary to wrestling. The increase in injuries from the year 2000 to 2019 was significant (P < 0.05). The average age of patients was 15.73 (range: 3 to 59 years old). Virtually all of the injuries occurred in males (95.6%). The majority of patients was under the age of 18 (82.3%). With regard to race, white wrestlers (57.1%) comprised the majority of patients. Insight into race was not available for 1245 patients (27.8%). Most wrestling-related injuries took place during the winter season (60.6%). Concussion was the most common primary diagnosis (29.0%). The head (57.1%) was the most commonly injured craniomaxillofacial region. The most common setting in which the injury took place was a place of recreation/sports (49.9%). Among the mechanisms of injuries, the take-down (26.5%) was the most common. Patients who were thrown/taken down (5.04%) were significantly more likely to get admitted (P < 0.01) relative to patients who were injured otherwise (2.6%). Similarly, patients who fell/tripped (6.6%) were significantly more likely to get admitted (P < 0.05) relative to patients who were injured otherwise (3.1%). While cases of concussion (6.0%) were significantly more likely to get admitted (P < 0.01) relative to other cases, cases of contusions/abrasions (0.6%) were significantly less likely to get admitted (P < 0.01) relative to other cases. Similar to contusions/abrasions (0.2%), lacerations were significantly less likely to get admitted (P < 0.01) relative to other cases. Patients aged 12-18 (P < 0.01) were most likely to suffer concussions, whereas patients aged 19-34 (P < 0.01) were least likely to suffer concussions. In contrast to concussions, patients aged 12-18 (P < 0.01) were least likely to suffer lacerations, whereas patients aged 19-34 (P < 0.01) were most likely to suffer lacerations. Patients aged 6-11 (P < 0.01) were most likely to be thrown/taken-down whereas patients aged 19-34 (P < 0.01) were least likely to be thrown. Patients aged 19-34 (P < 0.01) were most likely to be collided against intentionally, while patients aged 6-11 (P < 0.01) were least likely to be collided against intentionally. Patients aged 34 years or older were most likely to fall/trip, while patients aged 12-18 (P < 0.01) were least likely to fall/trip.

CONCLUSIONS

Certain types of injuries that occur during wrestling are more or less common depending on the age groups involved in the sport. Concussions were the most common injury incurred overall, and the head is the most commonly affected craniomaxillofacial area. Take-downs were the most likely mechanism of injury to lead to hospital admissions. The average number of wrestling injuries increased over 20 years being analyzed in this study. Future studies should investigate methods to lessen concussions in wrestling, decrease the number of illegal moves performed, and look into ways to mitigate harm from take-downs, given the increasing number of injuries acquired from this sport.

Prevalence, Patterns, and Characteristics of Eye Injuries in Professional Mixed Martial Arts

Purpose

To describe the frequency and type of eye injuries in fighters in mixed martial arts (MMA) competition.

Methods

Fight result data were collected from the Nevada Athletic Commission database from 2001 to 2020. Any fighters in a professional mixed martial arts (MMA) contest with an eye injury were included. Main outcome measures included frequency and rate of eye injuries per fight and the types of eye injuries. Secondary outcome measures were gender, laterality, decision type, and length of no-contact recommended.

Results

Of the 256 MMA events in the database, 187 events (73.3%) had at least one eye injury. Of a total 2208 fights at these events, there were 363 fighters who sustained 369 eye injuries, with the yearly rate of eye injuries per 100 fighters ranging from 2.56 to 12.22. The most common injuries were eyebrow and eyelid lacerations (n=160, 43%), lacerations around the eye (n=98, 27%), and orbital fractures (n=62, 17%). Most eye injuries were right sided (n=197, 53.3%) and the majority of fighters with eye injuries lost their match (n=228, 62.8%). Fifty-seven fighters were recommended for further ophthalmology clearance after the match. The most common reasons for recommended ophthalmology follow-up was orbital fracture (n=25, 44%) and retinal injury (n=7, 12%). Forty-three fighters received no-contact requirements relating to their injury for an average of 8.9 weeks (range 1–24 weeks).

Conclusion

Ophthalmic injuries in professional MMA were prevalent, were most often lacerations surrounding the eye, and often accompanied the fighter losing their match.

Adult Maxillofacial Trauma Patterns in American Football

INTRODUCTION

The authors aimed to identify and categorize adult maxillofacial trauma patterns in the setting of American football.

METHODS

The National Electronic Injury Surveillance System was accessed to identify adult patients presenting with football-related head and facial injuries from 2009 to 2018. Data surrounding each event were collected including age, injury type, injury location, and disposition of the patient. Chi-squared testing was performed to compare categorical variables, with a Bonferroni correction applied.

RESULTS

During the study period, 1784 total patients (national estimate = 65,052) were identified. The average age for this cohort was 27.26 (SD ± 8.49), with young adults (86.1%) and males (87.9%) sustaining the majority of injuries. Lacerations were the most common injury type (43.1%). Maxillofacial fractures comprised 15.8% of the sample, with nasal bone (52.8%) being the most common subtype. Female patients were significantly more likely to present with head injuries than men (46.8% versus 29.0%, P < 0.001). Young and middle-aged adults combined were more likely to be discharged from the emergency department, whereas the elderly were significantly less likely (P = 0.002). Patients with fractures were significantly more likely to be admitted to the hospital compared to all other types of injuries (P < 0.001).

CONCLUSIONS

An understanding of maxillofacial injuries while participating in American football is important in developing safety initiatives. To address these, it is crucial that providers understand the patterns of craniofacial injuries as they relate to American football trauma.

Rolling With the Punches: A National Electronic Injury Surveillance System Database Study of Craniofacial Injuries in Boxing

INTRODUCTION

Boxing is a popular combat sport in which competitors may sustain high impact blows to the face. For this reason, they are at high risk for craniofacial injuries; however, data on facial injuries specific to boxing remains sparse. Studies on safety measures, such as headgear, to prevent such injuries in boxing have been inconclusive. Boxing is popular with a wide audience. However, there is no consensus on safety measures across different populations involved in boxing due to lack of data. The objective of this study is to characterize the demography and incidence of injury types of patients presenting to emergency departments with boxing-related craniofacial injuries on a national scale in order to facilitate the establishment of evidence-based safety guidelines for prevention of boxing-related injuries.

METHODS

The National Electronic Injury Surveillance System database was searched for boxing-related craniofacial injuries from the last 10 years (2010-2019). Injuries involving boxing were isolated and organized into 5-year age groups. Information on demographics and injury type was extracted from the National Electronic Injury Surveillance System database. Statistical analysis was performed between different age and gender groups.

RESULTS

A total of 749 boxing-related craniofacial injuries treated in US emergency departments between 2010 and 2019 were recorded. The 19 to 34-year-old age group had the highest number of cases (54%), followed by the 12 to 18-year-old age group (31%). The most common injury types within both of these age groups were concussions and lacerations. This difference was found to be significant when compared to other craniofacial injury types (P < 0.05). The majority of athletes in these age groups were male (93% and 91%, respectively). Analysis of sex differences demonstrated concussions were more common in females compared to other injury types, whereas lacerations in males were more common compared to other injury types; these differences were found to be significant (P < 0.05).

CONCLUSIONS

The high incidence of boxing-related craniofacial injuries such as concussions and lacerations incurred in young adults (19-34 years) and adolescents (12-18 years) indicate that protective measures such as community-based safety interventions and revised guidelines for protective equipment may be indicated in these groups to protect against craniofacial injuries such as lacerations and concussions. Further studies are required to develop algorithms for management of boxing-related craniofacial injuries and to evaluate the safety and efficacy of protective equipment such as boxing headgear on concussions.

Rugby-related adult maxillofacial trauma injuries: a NEISS database study

PURPOSE

The primary objective of this study is to delineate the data on maxillofacial trauma in rugby utilizing the National Electronic Injury Surveillance System (NEISS) database. Specifically, we want to establish the prevalence of facial rugby injuries in terms of age, mechanism of injury, and degree of injury in order to develop ways to limit facial trauma in the future.

METHODS

The NEISS database was accessed in February 2020 in order to identify adult patients (> 19 years of age) presenting to the emergence department (ED) for rugby-related head and facial injuries from the previous 10 years (2009-2018). Descriptive statistics were organized and presented. Chi-squared testing (χ²) was performed to compare categorical variables, and ANOVA was performed to compare continuous variables.

RESULTS

A total of 507 patients (national estimate = 18,952) from 2009 to 2018 were identified as appropriate for study inclusion. The most common injuries were those to the facial region including the eyelid, eye area, and nose (59.4%). The most frequently encountered facial fracture while playing rugby was the nasal bone (58.6%). Overall, 98.4% of patients who presented to the ED with rugby injuries were treated and released, 1.2% were admitted or observed, and 0.4% left against medical advice.

CONCLUSIONS

When evaluating a patient with a rugby-related injury, one should expect injuries to the eyelid, eye area, or nose. The most common fracture pattern will most likely be nasal bone. Despite these injuries, the vast majority of patients will be treated and released.

ASSOCIATION BETWEEN LEVELS OF SPORTS PARTICIPATION AND ORAL INJURIES AMONG COMBAT ATHLETES

ABSTRACT Introduction Oral injuries are common traumas in combat sports due to the aggressive nature of both offense and defense. Sports mouth guards are made to reduce the risk of traumatic face and jaw injuries and concussions during sports activities. Objective The objective of this study was to determine the prevalence of oral injuries in combat sports and to examine the association between participation levels and percentage of injury occurrence. Methods One hundred and eight participants (mean age: 22.42 ± 2.162 years) who were involved in sparring events were recruited. Data were collected using a questionnaire consisting of 22 questions about the demographic profile of the athletes, their injury experience and type of injuries sustained, awareness and use of mouth guards in sports activities. Descriptive analysis, Chi-square test, and one-way analysis of variance (ANOVA) were applied for data analysis. Results Almost 77% of participants had experienced oral injuries during sports activities and nearly 90% were aware that oral injuries can be reduced by using mouth guards. In addition, 52.7% of participants complained that the mouth guard is not comfortable to use during sports activities. Findings revealed a significant moderate association between levels of participation and number of oral injuries ( p = 0.013). One-way ANOVA showed a significant mean difference in the rate of oral injury for the four levels of participation groups F (3, 104) = 6.21, p = 0.011. Post-hoc comparisons using the Bonferroni test indicated a significant mean difference between university-state levels ( p = 0.033) and university-national levels ( p = 0.028). Conclusion This study revealed that higher levels of participation in sports have a higher risk of injury. It was also found that the discomfort of using a mouth guard can be reduced if the coaches make the athletes wear proper mouth guards that follow the recommended specifications. Level of evidence IIIb; Case control study.

Incidence of Combat Sport-Related Mild Traumatic Brain Injuries Presenting to the Emergency Department From 2012 to 2016

OBJECTIVES

We sought to investigate the incidence and characteristics of traumatic brain injuries [mild traumatic brain injury (MTBI)] presenting to the emergency department as a result of boxing, wrestling, and martial arts (MA).

DESIGN

Retrospective cross-sectional study of MTBI in combat sport athletes who were evaluated in emergency departments in the United States.

SETTING

Patient data were taken from the National Electronic Injury Surveillance System.

PARTICIPANTS

All patients with MTBI from 2012 to 2016, which occurred during participation in boxing, MA, or wrestling.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The incidence of combat sport-related MTBI presenting to emergency departments in the United States.

RESULTS

The mean annual incidence of MTBI due to wrestling was significantly larger (269.3 per 100 000 person-years) than boxing (85.6 per 100 000 person-years) and MA (61.0 per 100 000 person-years) (P < 0.01). The average age at injury was significantly lower for wrestling compared with boxing and MA (15.0 years [SD ± 3.9] vs 21.7 years [SD ± 8.2] vs 19.9 years [SD ± 10.5]; P < 0.01). A significantly larger proportion of MTBIs (95.3%; P < 0.01) in patients younger than 20 years were related to wrestling, compared with boxing (55.8%) and MA (54.1%). Most patients with combat sport-related MTBIs were treated and discharged (96.3%), with only 1.7% of patients being admitted and 0.6% of patients being held for observation.

CONCLUSION

Combat sports athletes are at high risk of sustaining an MTBI. Such athletes presenting to the emergency department for combat sport-related MTBI were more likely to be male and younger than 20 years. Of these athletes, wrestlers experience the highest incidence of MTBI-related emergency department visits.

Head and Neck Injuries from Rock Climbing: A Query of the National Electronic Injury Surveillance System

Objective:

We describe the incidence and characteristics of patients with head and neck injuries from rock climbing who present to United States emergency departments and evaluate predictors of hospitalization.

Methods:

The National Electronic Injury Surveillance System (NEISS) database was queried for rock climbing injuries to the head, face, mouth, neck, and ear under product code “mountain climbing” from the years 2009 to 2018. Demographics, injury characteristics, and disposition data were reviewed. Data were evaluated using chi-square analysis with Cochran-Mantel-Haenszal odds ratios (ORs).

Results:

An estimated 5067 patients (from 129 raw NEISS case numbers) suffered head and neck injuries from rock climbing nationally from 2009 to 2018. Concussion/closed head injury was the most common injury (44%), followed by laceration (23%), soft tissue injury (15%), neck strain/sprain (6%), skull fracture (3%), facial fracture (3%), intracranial hemorrhage (3%), cervical spine fracture (2%), unspecified facial trauma (1%), and dental trauma (0.3%). Males more frequently suffered lacerations (OR 1.6), soft tissue injuries (OR 23.3), cervical spine fractures (OR 336.7), intracranial hemorrhage (OR 582.0), and skull fractures (OR 6.2) than females. Compared to shorter falls, falls over 20 ft were more commonly associated with laceration (OR 2.0), soft tissue injury (OR 3.5), facial fracture (OR 7.5), dental trauma (OR 6.6), intracranial hemorrhage (OR 951.8), skull fracture (OR 81.2), and hospitalization (OR 3.8). Injuries associated with hospitalization included facial fracture (OR 23.7), cervical spine fracture (OR 24.6), intracranial hemorrhage (OR 2210.2), and skull fracture (OR 9.8).

Conclusions:

Concussions and facial lacerations are the most common head and neck injuries from rock climbing. Males more commonly suffer severe injuries. Falls over 20 ft are associated with more severe injuries and an increased likelihood of hospitalization.

Impact Protection Potential of Mammalian Hair: Testing the Pugilism Hypothesis for the Evolution of Human Facial Hair

Because facial hair is one of the most sexually dimorphic features of humans (Homo sapiens) and is often perceived as an indicator of masculinity and social dominance, human facial hair has been suggested to play a role in male contest competition. Some authors have proposed that the beard may function similar to the long hair of a lion’s mane, serving to protect vital areas like the throat and jaw from lethal attacks. This is consistent with the observation that the mandible, which is superficially covered by the beard, is one of the most commonly fractured facial bones in interpersonal violence. We hypothesized that beards protect the skin and bones of the face when human males fight by absorbing and dispersing the energy of a blunt impact. We tested this hypothesis by measuring impact force and energy absorbed by a fiber epoxy composite, which served as a bone analog, when it was covered with skin that had thick hair (referred to here as “furred”) versus skin with no hair (referred to here as “sheared” and “plucked”). We covered the epoxy composite with segments of skin dissected from domestic sheep (Ovis aries), and used a drop weight impact tester affixed with a load cell to collect force versus time data. Tissue samples were prepared in three conditions: furred (n = 20), plucked (n = 20), and sheared (n = 20). We found that fully furred samples were capable of absorbing more energy than plucked and sheared samples. For example, peak force was 16% greater and total energy absorbed was 37% greater in the furred compared to the plucked samples. These differences were due in part to a longer time frame of force delivery in the furred samples. These data support the hypothesis that human beards protect vulnerable regions of the facial skeleton from damaging strikes.

Evaluation and Management of Sports-Related Lacerations of the Head and Neck

Soft tissue injuries to the head and neck are a common occurrence in sports. These anatomical regions are somewhat predisposed because of the "athletic stance" that is utilized in many close-contact sports. Although appropriate use of protective equipment, including mouth guards, helmets, and face shields, has reduced the incidence and severity of these injuries, they still occur regularly. To provide appropriate medical care, one must possess adequate knowledge of the superficial and deep anatomical structures, fundamental knowledge and skill in regard to wound care, and awareness of potential poor outcomes related to lacerations of unique structures, such as the mouth, eye, or ear.

Brazilian Jiu Jitsu, Judo, and Mixed Martial Arts Injuries Presenting to United States Emergency Departments, 2008-2015

Limited research has systematically examined injuries resulting from Brazilian Jiu Jitsu (BJJ), Judo, and mixed martial arts (MMA), especially when compared to more well-known or -established martial arts. These three combative sports differ substantially regarding their rules and techniques. BJJ emphasizes ground positioning and submission, Judo rewards throwing an opponent on their back with submission ending the match, and MMA emphasizes knocking out or forcing the submission of one's opponent. We examined injuries, among people of any age, experienced from participation in BJJ, Judo, and MMA. We analyzed data from the United States (U.S.) Consumer Product Safety Commission National Electronic Injury Surveillance System to create estimates of injuries presenting to U.S. emergency departments (EDs). We compared injury profiles between sports, including estimated numbers of injuries, their site, type, and mechanism. Participation in BJJ, Judo, and MMA resulted in an estimated 39,181 injuries presenting to U.S. EDs from 2008 through 2015. Strains and sprains were the most common diagnoses for BJJ and Judo participants, whereas abrasions/contusions were the most commonly diagnosed MMA injury. Being struck resulted in the majority of injuries for all three sports. The head was the most injured body region for BJJ and MMA, whereas the leg was the most injured body region for Judo. Finally, the majority of BJJ and Judo injuries occurred during noncompetitive grappling, whereas most MMA injuries occurred during competition. Our study adds to the limited literature examining injuries from BJJ, Judo, and MMA using data from a probability sample and is an initial step towards understanding the national burden of injury from participation in these sports. Given the quantity and severity of injuries sustained by participants, additional research is needed to assess the riskiness of participation and the effectiveness of interventions, such as improved personal protective gear and mats, as a means to prevent commonly occurring injuries.

Contact sport related head and neck injuries in pediatric athletes

OBJECTIVES

To describe the type and frequency of sports related pediatric head and neck trauma.

METHODS

The National Electronic Injury Surveillance System (NEISS) was searched for football, basketball, soccer, lacrosse and ice hockey related facial injuries. Cross-sectional analysis of incidence, age, and sex and specific injury diagnoses, mechanisms, and facial locations were performed. We focused on craniofacial and soft tissue injuries and excluded patients with concussion or other neurological injuries.

RESULTS

A total of 24,905 cases were identified in the NEISS database, corresponding to an estimated, 764,293 emergency department visits. The most hazardous sports were basketball, accounting for 356,188 visits (46.6%), football with 249,633 visits (32.6%), and soccer with 128,113 (14.7%) visits. Lacrosse and ice hockey accounted for 16,869 (1.9%) and 13,490 (1.5%) visits, respectively. There has been a decrease in injuries over the past 10 years, particularly for football (53%), ice hockey (46%), and lacrosse (41%). Soccer (13%) and basketball (9%) noticed the smallest decreases.

CONCLUSION

Children who play basketball, football and soccer are especially prone to emergency department visits related to the head and neck. Overall, there has been an improvement in number of injuries across the five sports investigated. Sports amenable to head and neck protective equipment saw the largest improvement (football, ice hockey, lacrosse), whereas only small decreases were noted in basketball and soccer. Changes in regulations for sports not amenable to more protective equipment may help decrease adverse events.

Positive and Negative Themes Depicted in Combat-Related Sports Films

Participation in boxing, mixed martial arts, and wrestling is extremely popular among children and adolescents. The objective of this study was to determine themes depicted in a select number of combat-related films. Twenty films were independently viewed and analyzed by 4 reviewers. The average number of positive and negative themes was 34.4 and 18.1 mean events/hour for all included films, respectively. The most common positive themes were "positive interactions with family/friends/fans," "importance of mentorship," and "positive interactions with a coach/trainer" (4.23, 3.63, and 3.06 mean events/hour, respectively). The most common negative themes were "choosing to do the wrong thing," "negative interactions with family/friends/fans," and "poor sportsmanship" (2.70, 2.00, and 1.58 mean events/hour, respectively). In conclusion, the co-viewing of combat-related films among pediatric athletes and their coaches/trainers and/or parents in order to focus on "teachable moments" may encourage the acquisition and development of positive themes and the avoidance and de-emphasis of negative themes.

Epidemiology of Achilles Tendon Ruptures in the United States: Athletic and Nonathletic Injuries From 2012 to 2016

Background

Achilles tendon (AT) ruptures are one of the most common tendon ruptures, but there have been no studies investigating these injuries in the United States (US) using data representative of the entire US population.

Purpose/Hypothesis

The purpose of this study was to determine the incidence and risk factors for AT ruptures in the US. We hypothesized that male sex, older age, and sport participation would increase the risk for AT ruptures.

Study Design

Descriptive epidemiology study.

Methods

All patients presenting to an emergency department with ruptured AT in the US from 2012 through 2016 were selected from the National Electronic Injury Surveillance System (NEISS) database. Incidence was calculated for sex, race, and age. AT ruptures were characterized based on the mechanism of injury, with subanalyses performed on sport-related AT ruptures to examine sex-, race-, and age-related differences.

Results

From 2012 to 2016, a significant increase in the incidence of AT ruptures was observed, from 1.8 per 100,000 person-years in 2012 to 2.5 per 100,000 person-years in 2016 (P < .01), for an overall incidence of 2.1 per 100,000 person-years. The majority of AT ruptures occurred in male compared with female patients, with an incidence rate ratio of 3.5 (P < .01). The largest overall incidence of AT ruptures occurred in those aged 20-39 years for male patients (5.6/100,000 person-years) and in those aged 40-59 years for female patients (1.2/100,000 person-years). The largest rise in the incidence of AT ruptures during the study period was observed in patients aged 40-59 years (78% increase). The most common injury mechanism was participation in a sport or recreational activity (81.9% of all injuries), with basketball being the most common overall cause of AT ruptures.

Conclusion

While AT ruptures in the US most commonly occur in young male patients (20-39 years old), the largest rise in the incidence was observed in middle-aged patients (40-59 years old), with participation in recreational sports being the most likely mechanism. Recognizing high-risk patients can help physicians counsel them and recommend strategies for injury prevention.

Epidemiology of boxing-related upper extremity injuries in the United States

OBJECTIVE

The incidence of boxing-related upper-extremity (UE) injuries in the United States has not been well characterized. Recent rule changes have been made to make participation safer for athletes, although the consequences of such rule changes on injury rates is unclear. Therefore, we sought to determine the incidence, characteristics, and trends of boxing-related UE injuries.

METHODS

The National Electronic Injury Surveillance System (NEISS) was queried for the years 2012-2016. All UE injuries related to boxing from 2012 to 2016 that occurred during organized boxing participation were selected. Examined variables included injured body party, injury diagnosis, patient age, and sex. Annual injury incidence rates by body part and diagnosis were calculated.

RESULTS

The mean incidence of boxing-related UE injuries from 2012 to 2016 was 673 injuries (95% CI 537-809) per 100,000 person-years, with hand fractures being the most common injury (132 (95% CI 130-135) per 100,000 person-years). The incidence of UE injury significantly declined from 865 (95% CI 846-884) per 100,000 person-years in 2012 to 656 (95% CI 642-671) per 100,000 person-years in 2016 (p < 0.01). Injuries to the hand exhibited the largest decrease, declining by 33%. The majority of boxers sustaining UE injuries were male (84.4%) and between the ages of 20-39 (59.9%).

CONCLUSIONS

Injuries to the UE due to participation in boxing accounted for thousands of emergency department visits in the United States annually, with males younger than 20 years of age, most susceptible to injury. Injuries to the hand, wrist and shoulder occurred at the highest rate. Finally, following rule changes made by sanctioning organizations in 2013, a significant decline in boxing-related UE injuries were observed.

Traumatic Facial Injuries Among Elderly Nursing Home Residents: Never Event or Frequent Occurrence?

Importance

As the nursing home population continues to increase, an understanding of preventable injuries becomes exceedingly important. Although other fall-related injuries have been characterized, little attention has been dedicated to facial trauma.

Objectives

To estimate the incidence of facial trauma among nursing home residents and detail mechanisms of injury, injury characteristics, and patient demographic data.

Design, Setting, and Participants

The National Electronic Injury Surveillance System was used to calculate a weighted national incidence of facial trauma among individuals older than 60 years from a nationally representative collection of emergency departments from January 1, 2011, through December 31, 2015. Entries were screened for nursing home residents, and diagnosis, anatomical site, demographic data, and mechanism of injury were analyzed.

Results

There were 109 795 nursing home residents (median age, 84.1 years; interquartile range, 79-89 years; 71 466 women [65.1%]) who required emergency department care for facial trauma. Women sustained a greater proportion of injuries with increasing age. The most common injuries were lacerations (48 679 [44.3%]), other soft-tissue injuries (45 911 [41.8%]; avulsions, contusions, and hematomas), and fractures (13 814 [12.6%]). Nasal (9331 [67.5%]) and orbital (1144 [8.3%]) fractures were the most common sites. The most common injury causes were direct contact with structural housing elements or fixed items (62 604 [57.0%]) and transfer to and from bed (24 870 [22.6%]).

Conclusions and Relevance

Despite falls being considered a Centers for Medicare & Medicaid Services preventable never event in hospitals, our analysis in the nursing home setting found more than 100 000 facial injuries during 5 years, suggesting these underappreciated injuries contribute substantially to health care expenditures. Although structural elements facilitated the greatest number of falls, transfer to and from bed remains a significant mechanism, suggesting an area for intervention.

Big data in facial plastic and reconstructive surgery: from large databases to registries

PURPOSE OF REVIEW

There are many limitations to performing clinical research with high levels of evidence in facial plastic and reconstructive surgery (FPRS), such as randomization into surgical groups and sample size recruitment. Therefore, additional avenues for exploring research should be explored using big data, from databases to registries. Other organizations have developed these tools in the evolving landscape of outcomes measurement and value in healthcare, which may serve as models for our specialty.

RECENT FINDINGS

Over the last 5 years, FPRS literature of large-scale outcomes research, utilizing several administrative databases, has steadily grown. Our objectives are to describe key administrative databases, strengths and weaknesses of each, and identify recent FPRS publications utilizing big data. A registry with FPRS defined outcomes has the most potential.

SUMMARY

Although FPRS research has trended to a more evidence-based approach in the modern healthcare era, gaps persist. Several large administrative databases or registries can address voids in outcomes research within FPRS.

Pediatric rhinoplasty: A discussion of perioperative considerations and systematic review

OBJECTIVES

Pediatric rhinoplasty has traditionally raised numerous concerns, including its impact on growth as well as the psychological sequelae of undergoing a potentially appearance-altering procedure. Our objective was to critically evaluate available individual patient data relevant to pediatric rhinoplasty, and further discuss perioperative considerations.

METHODS

A systematic review was conducted using PubMed/MEDLINE databases. Data extracted and analyzed from included studies included patient demographics, surgical indications, operative approaches, outcomes, complications, revision rates, and other clinical considerations.

RESULTS

Seven studies encompassing 253 patients were included, with age ranging from 7 months to 19 years. Two-thirds of patients were male. 41.7% reported antecedent trauma, and common overall surgical indications included "functional aesthetic" (24.5%) followed by cleft lip nasal deformity (15.8%). The majority (79.1%) underwent open approaches, and 71.1% of patients underwent concomitant septal intervention. The most frequently used grafting materials were septal cartilage (52.8%) and conchal cartilage (16.5%). Surgical outcomes were heterogeneous among these studies. Complication rates were only specified in 5 of the 7 studies and totaled 57 patients (39.6%). Aesthetic dissatisfaction (11.8%) and postoperative nasal obstruction (5.6%) were the most commonly reported complications. Revisions were performed in 13.5%.

CONCLUSION

Rhinoplasty is safe in the pediatric population, although revisions rates appear greater than those reported in adults. This study of 253 represents the largest pooled sample size to date; nonetheless, non-standardized outcome measures, minimal long-term followup data, and lack of discussion regarding psychological sequelae all contribute to the need for further high-quality studies evaluating this topic.
