Background: Skateboarding is an increasingly popular leisure activity for youth, yet injuries due to falls are common. This study aimed to identify the features at skateparks and tricks performed by youth that pose an increased risk of falls in skateboarders., Method: Video recordings were unobtrusively taken at a large skatepark of youth designated as young (11-15 years) or old (16-20 years). Videos were coded to identify the popular skatepark features used and tricks performed, and to assign a fall severity outcome rating for each feature and each type of trick attempted., Results: The results identify features and tricks that pose increased risk of falling for youth at skateparks., Conclusions: Implications for injury prevention are discussed, including a consideration of environmental (skatepark design) and individual (youth behaviour) factors relevant to reducing skateboarding injuries due to falls among youth., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objectives: To describe the frequency, type, and severity of health problems in long-track speed skating to inform injury prevention strategies., Methods: We prospectively collected weekly health and sport exposure data on 84 highly trained Dutch athletes aged 15-21 years during the 2019/2020 season using the Oslo Sports Trauma Research Centre questionnaire on Health Problems and the trainers' documentation. We categorised health problems into acute or repetitive mechanisms of injury or illness and calculated incidences (per 1000 sports exposure hours), weekly prevalence and burden (days of time loss per 1000 sports exposure hours) related to the affected body region., Results: We registered 283 health problems (187 injuries, 96 illnesses), yielding an average weekly prevalence of health problems of 30.5% (95% CI 28.7% to 32.2%). Incidence rates were 2.0/1000 hours for acute mechanism injuries (95% CI 1.5 to 2.5) and 3.2/1000 hours for illnesses (95% CI 2.6 to 3.9). For acute mechanism injuries the head, shoulder and lumbosacral region had the highest injury burden of 5.6 (95% CI 4.8 to 6.5), 2.9 (95% CI 2.3 to 3.5) and 2.2 (95% CI 1.7 to 2.8) days of time loss/1000 hours, respectively. For repetitive mechanism injuries, the knee, thoracic spine, lower leg and lumbosacral region had the highest injury burden, with 11.0 (95% CI 9.8 to 12.2), 6.8 (95% CI 5.9 to 7.7), 3.9 (95% CI 3.2 to 4.6) and 2.5 (95% CI 1.9 to 3.1) days of time loss/1000 hours, respectively., Conclusion: Our study demonstrated a high prevalence of acute and repetitive mechanism injuries in speed skating. These results can guide future research and priorities for injury prevention., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objectives: Determining the rate of injuries related to a certain sport is accepted as the primary step toward designing, implementing and evaluating injury prevention programs. This observational and retrospective study was to examine the injuries sustained by elite young Spanish inline speed skaters during a season., Methods: Athletes participating in the national championship ( n  = 80) were surveyed via an anonymous online questionnaire to screen for injury characteristics: incidence, location, and tissue affected; plus training information and demographics., Results: A total of 52 injuries were recorded across 33,351 hours of exposure, which gives a rate of 1.65/1,000 h. The lower body comprised 79% of the total amount of injuries (1.3/1000 h), and the main areas affected were the thigh and foot, accounting for 25% and 19.2% of the recorded injuries, respectively. Musculotendinous injuries were the most frequent, with an incidence of 0.92/1000 h. No significant gender differences were observed for any of the variables studied., Conclusion: Speed skating can be considered a low injury rate sport based on our findings. The risk of sustaining an injury was independent of gender, age, and BMI.

Skateboarding is an increasingly popular sport among youth, despite the fact that they are a high-risk group for injuries during this activity. The purpose of this study was twofold: to explore youths' perceptions about the influences that peers and parents have on their skateboarding; and to identify factors that affect their decisions about returning to the sport after injury. Virtual semi-structured interviews were conducted with 26 youth, 14-17 years of age, who had experienced a medically-treated injury while skateboarding during the past year. Applying thematic analyses, major findings indicated that sharing the activity with peers fosters psychological well-being, companionship, and a valued sense of community that motivates return to the sport even after serious injury and sometimes before they are fully physically ready to do so safely. Parental concerns about physical injury (vulnerability, severity) were acknowledged but not influential, with youth feeling that parents do not appreciate the valued mental health benefits that they experience from the skateboarding community. Youth reported withholding injury information from parents, hiding injuries and downplaying their severity, and not always disclosing returning to the sport. Youths' decisions to return to the sport after injury was motivated by their feelings that skateboarding enhances their sense of identity, promotes their mental health, and provides respite because it allows them to escape from reality temporarily. Recommendations for reducing risk of injury to youth skateboarders at skateparks are provided., Competing Interests: Declaration of competing interest No authors have any competing interests., (Copyright © 2023 Elsevier Ltd.

Introduction: Figure skating combines esthetic components with high impact, technically demanding elements requiring high volume repetitive training. The evidence base for the sport is limited, particularly regarding stress fracture injuries. This study aims to describe the prevalence and anatomical distribution of stress fracture injuries and assess for risk factors, as well as associations with acute fractures., Methods: An online anonymous retrospective survey of competitive figure skaters was distributed through social media networks and e-mail for completion by skaters from all three disciplines of figure skating., Results: In a sample of 164 skaters from novice to Olympic level, career prevalence of stress fractures was 24.4%, most commonly affecting tibia and ankle. There was statistically significant increased risk of stress fracture in those training ≥12 times/week (33.3% vs. 17.8%; P = 0.028) but no increased risk associated with level or gender of skater. There was a higher prevalence of acute fracture in those with a history of stress fracture (45.0% vs. 21.8%; P = 0.007)., Conclusions: Figure skaters are at a high risk of stress fractures, independent of the level performed at. There is a higher risk in those training more frequently and an association with additional acute fractures. Results advocate education on fracture features and bone health measures to skaters, coaches, and physicians, at all levels of the sport to facilitate early diagnosis and management.

In pair skating and ice dance, performance seems to have increased at international competitions, which is potentially associated with changes in athlete age. We hypothesized increasing age, numbers of total points and more complex jumps of the best elite couples at international championships in recent years. Corresponding data were assessed via the results databases of the European and World Championships, as well as the Winter Olympics since 2005. Linear regression statistics were conducted, and significance was assessed via one-way ANOVAs. There were no significant changes in age. Increases in total points were found in both disciplines (World and European Championships both p < 0.001 for both disciplines, Olympics pair skating p = 0.003, ice dance n/a). Significant increases were found in the number of double and triple twist jumps at the European Championships (Double p = 0.046, triple p = 0.041), but not at the World Championships or the Olympics. At the World Championships, single solo jumps decreased ( p = 0.031) in favor of triple jumps, which increased ( p = 0.020), without a similar effect at the European Championships or Olympics. In conclusion, increases in total points and more complex jumps were observed at international championships without associated changes in age. Attention should be given to possible changes in the incidence of acute and overuse injuries following this development.

Background: Skateboarding is a popular sport and U.S. trauma centers care for a significant number of skateboard-related injuries (SRIs). However, injury prevention strategies are still underdeveloped. This study was designed to compare the epidemiology, type, and location of skateboard injury as well as the use and influence of protective gear over two time periods., Methods: This is a retrospective National Trauma Data Bank study including all patients with SRIs between 2007and 2016. Study groups were divided into two 5-year periods: 2007-2011 and 2012-2016. The incidence and severity of traumatic brain injury (TBI), as well as the compliance and effectiveness of protective gear and skate parks, was assessed in various age groups in the two study periods using univariable and multivariable analyses. Univariable analysis was used to compare the two study periods, logistic regression analysis was performed to identify independent predictors of head injury and severe TBI., Results: 24,903 patients presented with SRIs: 10,594 from 2007 to 2011 and 14,309 from 2012 to 2016. Helmet use was low in both periods (5.7% and 5.4% respectively). The incidence of severe TBI (head AIS≥3) did not change significantly during the two periods (31.6% vs. 30.8%, p = 0.162). In children with severe TBI, there was no significant difference in helmet use across all ages, (10.4% vs. 11.5%, p = 0.467; 6.4% vs. 6.5%, p = 0.753; 4.2% vs. 3.7%, p = 0.201, respectively) with the lowest usage in the older than 16 years age group. On logistic regression, male gender (OR 1.526, 95% CI 1.372-1.698, p<0.001) was associated with increased odds of severe TBI, while helmet use (OR 0.534, 95% CI 0.455-0.627, p<0.001) and injuries at skate parks (OR 0.584, 95% CI 0.541-0.630, p<0.001), near home (OR 0.465, 95% CI 0.418-0.518, p<0.001), and public buildings (OR 0.386, 95% CI 0.440-0.541, p<0.001) were associated with reduced odds of severe TBI., Conclusions: Helmet use in patients with SRIs is low in all pediatric age groups. Helmet use and skate parks are protective against severe TBI. Older age children and male gender are at increased risk of severe TBI after skateboard-related injuries, and more targeted preventive education and legislation are needed., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021.

Objectives: The broad objective of this paper is to inform policy, practice and research regarding the management of head injury risks in competitive skateboarding. The main motivation for the current study was the question of mandating helmet use in competitive skateboarding. The specific aims are to present current knowledge on (A) head injury risks in skateboarding, (B) preliminary biomechanical data on falls and head injury risks in a selection of competitive skateboarding events similar to those planned for the Summer Olympics, (C) standards for skateboard-styled helmets and (D) impact performance of helmets commonly used in skateboarding., Methods: A narrative review of the published literature on head injuries in skateboarding was conducted. Videos of skateboarding competitions from Vans Park Professional League, Street League Skateboarding and Dew Tour were reviewed to describe crashes and falls. Standards databases including the International Organization for Standardization (ISO), British Standards Institution (BSI), Snell, United States Consumer Product Safety Commission (CPSC) and American Society for Testing and Materials (ASTM) were searched for skateboarding-styled helmet standards. A sample of helmets considered suitable for skateboarding was tested in standard impact tests., Results: The majority of previous literature focused on the paediatric population in a recreational setting with little data from competitive skateboarding. Head injuries comprised up to 75% of all injuries and helmet use was less than 35%. Video analysis identified high rates of falls and crashes during competitive skateboarding, but also a capacity for the athletes to control falls and limit head impacts. Less than 5% of competitive skateboarders wore helmets. In addition to dedicated national skateboard helmet standards, there are several national standards for skateboard-styled helmets. All helmets, with the exception of one uncertified helmet, had similar impact attenuation performance; that is, at 0.8 m drop height, 114-148 g; at 1.5 m, 173-220 g; and at 2.0 m, 219-259 g. Impact performance in the second impact was degraded in all helmets tested., Conclusion: Helmets styled for skateboarding are available 'off the shelf' that will offer protection to the head against skull fractures and intracranial injuries in competitive skateboarding. There is an urgent need to commence a programme of research and development to understanding and control head injury risks., Competing Interests: Competing interests: ASM is a member of the Australian Centre for Research into Injury in Sport and its Prevention (ACRISP) at Edith Cowan University.

Objective: To analyze the characteristics of injuries sustained by young figure skaters who were evaluated at regional pediatric sports medicine clinics., Design: Retrospective chart review (2003-2017)., Setting: Sports medicine clinics at a tertiary-level pediatric medical center., Patients: Two hundred ninety-four figure skaters (271 female and 23 male). Age rage: 9 to 19 years. Mean age: 14.2 ± 2.3 years., Interventions: None., Main Outcome Measures: Mechanism of injury (acute vs overuse), injured body areas, diagnoses for most commonly injured body areas, and distribution of bone stress injuries., Results: Eight hundred sixty-four figure skating-related injuries were identified. Approximately 68.9% were overuse and 31.1% were acute. In female figure skaters, the most frequently injured body areas were foot/ankle (29.6%), knee (19.3%), and back (15.8%). In male figure skaters, they were foot/ankle (25.4%), hip (16.4%), and knee (14.9%). Most common diagnoses at these body areas were tendinopathy (foot/ankle), extensor mechanism (knee), and posterior column bone stress injuries (back). All injuries to anterior knee structures, excluding bone contusions, were categorized as extensor mechanism injuries. About 11.8% of all injuries were bone stress reactions/fractures with the majority occurring at the back (42.2%), foot/ankle (32.4%), and lower leg (15.7%)., Conclusion: Most injuries sustained by figure skaters were overuse and occurred most commonly at the foot/ankle (29.6%), knee (19.3%), and back (15.8%). Approximately 1 in 10 injuries were bone stress reactions/fractures, and nearly 1 in every 3 skaters who presented with back pain was diagnosed with a posterior column bone stress injury. Health care providers who take care of young figure skaters need to maintain a high index of suspicion for overuse injuries, especially bone stress reactions/fractures., Competing Interests: The authors report no conflicts of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

A 13-year-old boy presented with gross hematuria following a skateboarding accident and was found to have cross-fused renal ectopia of the left kidney with a grade IV right renal laceration and urinary extravasation. Despite a double-J ureteral stent, urinoma drain, and indwelling bladder catheter, his urinoma drain maintained high output. He underwent a ureteral stent exchange and upsizing. A percutaneous nephrostomy tube was subsequently placed for maximal urinary diversion, which ultimately led to the resolution in his urinary leak. This case highlights our endourologic approach to manage a severe urinary leak despite conservative measures in a pediatric patient with a renal anomaly., (Copyright © 2020 Elsevier Inc.

A 20-year-old male military technician reported to a direct-access physical therapy clinic 1 week after falling off a skateboard. His primary complaint was left lateral ankle pain. Following examination, the physical therapist ordered ankle radiographs, which revealed a minimally displaced oblique trans-syndesmotic fibular fracture.

Context: Pain in sport has been normalized to the point where athletes are expected to ignore pain and remain in the game despite the possible detrimental consequences associated with playing through pain. While rehabilitation specialists may not have an influence on an athlete's competitive nature or the culture of risk they operate in, understanding the consequences of those factors on an athlete's physical well-being is definitely in their area of responsibility., Objective: To explore the factors associated with the experiences of subelite athletes who play through pain in gymnastics, rowing, and speed skating., Design: The authors conducted semistructured interviews with subelite athletes, coaches, and rehabilitation specialists. They recruited coach participants through their provincial sport organization. Athletes of the recruited coaches who were recovering from a musculoskeletal injury and training for a major competition were then recruited. They also recruited rehabilitation specialists who were known to treat subelite athletes independently by e-mail., Setting: An observation session was conducted at the athlete's training facility. Interviews were then conducted either in a room at the university or at a preferred sound-attenuated location suggested by the participant., Participants: The authors studied 5 coaches, 4 subelite athletes, and 3 rehabilitation specialists., Interventions: The authors photographed athletes during a practice shortly before an important competition, and we interviewed all the participants after that competition. Our photographs were used during the interview to stimulate discussion., Results: The participant interviews revealed 3 main themes related to playing through pain. They are: Listening to your body, Decision making, and Who decides., Conclusion: When subelite athletes, striving to be the best in their sport continue to train with the pain of an injury, performance is affected in the short-term and long-term consequences are also possible. Our study provides some insight into the contrasting forces that athletes balance as they decide to continue or to stop.

The sport of figure skating has evolved to include various disciplines and athletes continue to push the limits of the skills they perform, thus increasing the potential for injury in practice, as well as in competition. To provide optimal rink side coverage, health care professionals must be aware of the elements skaters perform and the injuries to be expected. Appropriate planning and coordination of medical services is required to ensure adequate and timely care of injured figure skaters. Protocols developed for local, national, and international events are available to assist in this process.

Since 2000, the number of emergency department visits and hospital admissions for children who have sustained a fall from a skateboard has undergone a noticeable decline. One possible explanation for this decline is that children today lead a more sedentary lifestyle and are not as engaged in outdoor physical activities as were children in previous generations. The profile of patients injured in skateboarding-related accidents has also changed since 2000. The percent minority, percent residents of large metropolitan areas, and percent who incur an injury on a street or highway have all increased during this time period. Data based on observations of riders in skateboard parks indicate that the overwhelming majority do not wear protective gear such as helmets, elbow/knee pads, or wrist guards, and that a sizable segment of riders compound their risk of injury by using headphones or earbuds when performing maneuvers.

Introduction: Hoverboards have become popular since they became available in 2015. We seek to provide an estimate of the number of injuries in the United States for 2015 and 2016, and to evaluate differences between adult and pediatric injury complexes., Methods: We performed a retrospective analysis of the National Electronic Injury Surveillance System (NEISS) from January 1, 2015 to December 31, 2016. Using the weighted design of the NEISS, a nationally representative sample could be determined., Results: During the 2 year period, there were 24,650 hoverboard related injuries (95% confidence interval [Cl], 17,635-31,664) in the US. The average age was 20.9 years old. There were 15,134 pediatric injuries (95%CI 9980-20,287) and 9515 adult injuries (95%CI 7185-11,845). Female patients compromised 51.2% of the sample. The upper extremity was the most common region injured [13,080 (95% CI 8848-17,311)] and fracture was the most common type of injury [10,074 (95% CI 6934-13,213)]. Hoverboard injuries increased from 2416 (95% CL 575-4245) in 2015 to 22,234 (95% CI 16,446-28,020) in 2016. Pediatric patients were more likely to be injured in the upper and lower extremity when compared to their adult cohort (p = 0.0031). Six percent of the cohort [1575 (95% CI 665-2485)] sustained critical injuries with pediatric patients being at 1.46 times higher risk for life threatening injuries., Conclusion: Emergency department (ED) visits for hoverboard related injuries appear to be increasing. Pediatric patients are more at risk for hoverboard related injuries than adults and almost 6% of ED visits involved critical injuries, highlighting that hoverboards may be more dangerous than previously recognized., (Copyright © 2018.

Introduction: Recreation on longboards is gaining in popularity. The purpose of this study is to detail the injury patterns, treatment and management of children with longboarding injuries seen at a level 1 pediatric trauma center., Methods: A retrospective review using our trauma registry from 2006 to 2016 of pediatric patients who sustained injuries while riding a longboard., Results: Of 12,920 injured children, 64 (0.5%) were treated for injuries that occurred while riding a longboard. Median age was 14.5 years (IQR 13.6, 15.4) and 84% were male. Fifty-one (80%) suffered a traumatic brain injury (TBI) including 32 intracranial hemorrhages (ICH), 17 concussions, and 31 skull fractures. Seven (11%) were wearing helmets. Three patients required neurosurgical intervention. Extremity fractures were the most common reason for surgery. Ninety-six percent of patients were admitted to the hospital with a median length of stay of 1 day (IQR 1, 3). All children survived to discharge. Compared with skateboard injuries during the same period, TBI, ICH, concussion, and skull fractures were all greater., Conclusions: TBI ranging from concussion to ICH requiring craniotomy is common in children injured while riding a longboard, and greater than rates after skateboarding injuries. Extremity fracture was the most common reason for operative intervention., Level of Evidence: III., (Copyright © 2018. Published by Elsevier Inc.)

Little is known about roller derby injuries. To describe the types of injuries that female roller derby athletes experience, quantify the incidence of injuries and examine the relationship between selected demographic variables and injuries. Women's roller derby leagues were contacted explaining the study and requesting participation. A second message was sent with the link to the electronic questionnaire to collect data from March to June 2015. Of the 1 395 respondents, 48.7% (679) reported having at least one injury in the previous 12 months. The skaters' average age was 32 and have played roller derby for four years. The most common injuries were to the ankles (22.5%), knees (21%) and head (11%). Of the head injuries, 75% were diagnosed with a concussion. This is the first study of woman's roller derby injuries. Understanding injuries that skaters incur may help leagues as they develop policies and specific injury prevention programmes.

Context:: As the popularity and technical demands of figure skating increase, so will the number of athletes presenting with sport-related problems., Evidence Acquisition:: Searches were performed across PubMed from 1980 to 2017. The keywords searched were skating, skaters, incidence, and injuries. The search was limited to English-language articles and human participants. Relevant articles were cross-referenced., Study Design:: Clinical review., Level of Evidence:: Level 5., Results:: Previous studies suggest an increase in incidence of figure skating injuries from 1982 to 2003. When combining all disciplines of figure skating, there is a similar proportion of acute and overuse injuries. Within disciplines, overuse injuries appear to be more common in singles skating, while acute injuries are more common in pairs skating, ice dancing, and synchronized skating. Lower extremity injuries are more common than upper extremity injuries in all disciplines, and pairs skating accounts for the majority of upper extremity injuries. Ankle sprains are the most common skating injury, and patellar tendinitis is the most common overuse injury across all disciplines. Stress fractures are the most common overuse injury in female singles skaters., Conclusion:: The predominance of overuse injuries in singles disciplines reflects their increasing technical difficulty, with more difficult jumps and longer training hours. Partner disciplines are more likely to involve acute injuries and upper extremity injuries due to high-risk throws and lifts. Emphasis should be placed on properly fitting skating boots, intrinsic foot and ankle strengthening, and lower extremity flexibility, which may prevent many of the common lower extremity and back injuries in figure skating.

Background: Oral lacerations represent a unique challenge for anesthesia in the emergency department. Many options exist for local anesthesia, but these options are often associated with pain from injections or anxiety from anticipated needle injection., Case Series: We introduce a novel and needleless approach to achieving local anesthesia for oral mucosa repair by dripping injectable lidocaine directly onto mucosal wounds prior to repair. This method is well tolerated and achieves appropriate anesthesia without undesirable side effects. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Dripped injectable lidocaine may be an alternative method for mucosal anesthesia in the pediatric population., (Copyright © 2018 Elsevier Inc.

Aim: Injuries involving non-motorised wheeled recreational vehicles (NMWRV) and bicycles are a common cause for hospitalisation in children. Studies show that helmet use whilst bicycle riding can decrease mortality and morbidity due to head injury. However, there remains an important proportion of children who are non-helmet users (NHU). This study aims to investigate helmet use and attitudes and injury patterns in children presenting with trauma after riding bicycles and other NMWRVs., Methods: A prospective cohort study was undertaken over 8 months of children aged 0-16 years, who presented with injury secondary to bicycle or NMWRV to the emergency department of two tertiary paediatric centres. Demographics, incident, injury severity and attitudes towards helmet use were compared between helmet users and NHU., Results: A total of 342 children were included - 41% (n = 139) scooter riders, 39% (n = 133) bicyclists, 18% (n = 61) skateboarders and 2% (n = 9) in-line skaters. Of those interviewed (n = 161), 58% (n = 93) wore a helmet, with children riding bicycles significantly more likely to be helmeted than NMWRV (75 vs. 48%, P = 0.01). NHU were more likely to be admitted to hospital (P = 0.05) and to sustain a major head injury (P = 0.009). The main influence on helmet use was parental rules. The biggest factor influencing non-helmet use was perceived low levels of danger., Conclusions: Despite legislation mandating this, helmet use is not universal in cyclists, particularly younger riders. Even fewer NMWRV riders use them. To promote helmet use, a multifaceted approach aimed at altering community norms and individual behaviours and attitudes is required., (© 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Background: Skateboarding is a popular recreation among children and adolescents. Injuries that result in presentation to emergency departments are varied including head injuries. The study aims to assess the type and severity of neurological damage to the brain and spine in children from injuries incurred while using a skateboard., Methods: After obtaining Ethics approval, a retrospective case review was performed of all admissions to all Brisbane, Australia public hospital neurosurgery departments of children 18 years and less who experienced injuries to the brain and spine for the years 2010-2014., Results: There were 51 skateboard-related admissions over the study period of which 94% were male. The mean age was 14.3 years. The Injury Severity Score (ISS) ranged from 1 to 38 with a mean of 11.4. A total of 70.5% of the ISS scores fell within the minor or moderate categories and 29.5% fell within the serious and severe categories. There were no ISS scores in the critical category. A total of 16 skull vault fractures and 14 skull base fractures were recorded. There were 13 extradural haematomas of which five were evacuated by craniotomy and one of whom experienced hemiplegia. There was a spinal cord injury with paraplegia. A range of other neurological complications occurred. There were no deaths., Conclusion: Uncommon but serious neurological morbidity accompanies skateboard use. Concerns remain about the level of helmet use and choice of unsafe locations for skateboarding., (© 2018 Royal Australasian College of Surgeons.)

Objective: To identify (1) the predominant level of evidence of the clinical studies regarding the hip pathology, risk factors, treatment, and clinical outcomes in artistic athletes (dancers, figure skaters, and gymnasts) (2) the most commonly reported hip pathology, risk factors, treatments, and clinical outcomes in dancers, figure skaters, and gymnasts., Methods: To conduct this systematic review PubMed, EMBASE, and Scopus databases were searched for relevant studies and pertinent data were collected from the eligible articles. Included were studies which reported hip injuries in artistic athletes, the risk factors, treatment, and/or the clinical outcomes. We excluded case reports or irrelevant studies. No meta-analysis was performed because of study heterogeneity. The methodical index for nonrandomized studies (MINORS) criteria were used for quality control., Main Results: Thirty-eight studies were included in the analysis. The mean MINORS score was 13.6 ± 4.6 points indicating fair quality of evidence of the included articles. The predominant level of evidence was level IV. Chondrolabral pathology and muscle injuries were the most commonly reported pathologies. We found only 2 risk factor analysis studies; however, many studies reported risk correlation between artistic sports or imaging findings and hip pathology. Treatment strategies were reported in only 7 studies, clinical outcomes are significantly underreported., Conclusion: Chondrolabral pathology was the most commonly reported hip pathology in artistic athletes, however, prospective cohort studies are necessary to really understand these injuries and their associated risk factors. The lack of clinical outcomes is significant and future data collection is required to assess the effectiveness of the various treatments.

Skateboarding has become an international action sport attractive to young people. For this reason, skateboarding has been promoted by some researchers as important for encouraging young people to become more physically active. However, skateboarding is also considered to be inherently dangerous by the medical and broader community and as a result skateboarding is banned in many places. This paper reviews scientific literature on the features, outcomes and risk factors related to skateboarding injuries. Findings suggest that while skateboarding injuries can be severe, skateboarding is not as dangerous as it might appear if appropriate risk management steps are taken. Skateboarding should be encouraged as a worthy physical activity and local communities should consider providing specialised, supervised spaces for young people to practice this sport.

Hoverboards pose a significant risk of musculoskeletal injury to pediatric riders. A prospectively enrolled cohort yielded 9 pediatric patients injured while riding hoverboards in 2016. Eight of the injuries involved the upper extremity, and one involved the lower extremity. No riders wore any safety equipment and injury patterns modeled those seen in skateboard riders., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Introduction: Since hoverboards became available in 2015, 2.5 million have been sold in the US. An increasing number of injuries related to their use have been reported, with limited data on associated injury patterns. We describe a case series of emergency department (ED) visits for hoverboard-related injuries., Methods: We performed a retrospective chart review on patients presenting to 10 EDs in southeastern Virginia from December 24, 2015, through June 30, 2016. We used a free-text search feature of the electronic medical record to identify patients documented to have the word "hoverboard" in the record. We reported descriptive statistics for patient demographics, types of injuries, body injury location, documented helmet use, injury severity score (ISS), length of stay in the ED, and ED charges., Results: We identified 83 patients in our study. The average age was 26 years old (18 months to 78 years). Of these patients, 53% were adults; the majority were female (61.4%) and African American (56.6%). The primary cause of injury was falls (91%), with an average ISS of 5.4 (0-10). The majority of injuries were contusions (37.3%) and fractures (36.1%). Pediatric patients tended to have more fractures than adults (46.2% vs 27.3%). Though 20% of patients had head injuries, only one patient reported using a helmet. The mean and median ED charges were $2,292.00 (SD $1,363.64) and $1,808.00, respectively. Head injuries resulted in a significantly higher cost when compared to other injuries; median cost was $2,846.00., Conclusion: While the overall ISS was low, more pediatric patients suffered fractures compared to adults. Documented helmet use was low, yet 20% of our population had head injuries. Further investigation into proper protective gear and training is warranted., Competing Interests: Conflicts of Interest: By the WestJEM article submission agreement, all authors are required to disclose all affiliations, funding sources and financial or management relationships that could be perceived as potential sources of bias.

Objective: The aim of this study was to identify the types of pediatric orthopedic extremity fractures that are sustained as a result of hoverboard (self-balancing, self-propelling, 2-wheeled boards) use., Methods: We performed a retrospective review of all orthopedic consultations from the emergency department at our institution from December 1 to 31, 2015. Data was collected on the injury mechanism, fracture location, management, and patient characteristics including sex, age, and hand dominance., Results: A total of 307 patients with acute extremity injuries were evaluated for a 31-day period. Hoverboard use was identified as the mechanism of injury in 36 patients with 36 fractures (11.7%). The mean age of these 36 patients was 11 years (range, 4-17 y), with most being male (69.4%). There were 35 upper extremity fractures and 1 lower extremity fracture. Eight (22.9%) of the 36 hoverboard patients required closed reduction in the emergency department either under conscious sedation or hematoma block performed with local anesthetic. Four patients (11.1%) required operative treatment., Conclusions: The overall incidence of extremity fractures due to hoverboard riding seen in our emergency department during the holiday season was relatively high compared with other common childhood activities. The vast majority of these fractures involved the upper extremities. A moderate percentage of these injuries required closed reduction in the emergency department or surgical treatment. Additional studies examining the use of protective equipment while riding hoverboards, time from initial hoverboard use to injury, supervision, and the cost of treating these injuries should be conducted to further elucidate the nature of these injuries and work toward prevention.

Objective: To determine the prevalence of musculoskeletal injuries and their relation to different presentation variables in inline speed skaters by age categories, between 8 and 23 years of age, from Villavicencio, Colombia., Methods: An observational cross-sectional or prevalence analytical study was developed by applying an information collection instrument that was designed and validated qualitatively and quantitatively. The instrument included variables associated with the presentation of lesions organized in five domains. The information collected was analyzed with descriptive statistics., Results: 66.7 % of the population studied were females, 39 % of skaters had between five and six years of sporting experience, and were in the transition category. Nine out of ten athletes trained more than five days a week, and the same proportion did three to five hours of daily training. The prevalence of musculoskeletal injuries was 53.7 % in the total population studied; 29.6 % had between one and two injuries, and 5.6% of injured skaters had between nine and ten injuries., Conclusions: Most of musculoskeletal injuries were related to the younger age categories, in precompetitive and specific preparation periods. The lower limbs were the most affected, to a greater extent, by bony and muscular lesions.

Background Fractures of the superior articular process are rarely seen in clinical practice. Repetitive spinal movements may lead to fractures of the pars interarticularis, resulting in spondylolysis. Traumatic spinal fractures often involve the vertebral body, transvers and/or the spinous processes. The superior articular processes, however, are seldom involved in both traumatic and stress-induced fractures. Purpose The purpose of this report is to present an unusual case of symptomatic bilateral fracture of the superior articular process of the sacrum in a 21-year-old speed skater. Study design This is a case report. Methods The patient was admitted for close observation after complaining of excruciating lower back pain and bilateral dysesthesia along the L5 nerve root. Post-myelography computed tomography (CT) revealed a bilateral facet joint deformity at L5/S1 and a bilateral fracture of the superior articular process of the sacrum. A facet joint block at the L5/S1 joint alleviated the pain, and a nerve root block at the L5 nerve root improved the dysesthesia. The patient underwent an L5/S1 decompression, whereby the nonunion bone fragments were removed, followed by a posterior lumbar inter-body fusion (PLIF) at L5/S1. Results The patient showed immediate improvement and returned to training six months post-operatively. Conclusion We have presented a case of bilateral fractures of the superior articular process of the sacrum in a speed skater. His presenting symptoms were similar to those found in patients with spondylolysis and the etiology appears to be similar. Surgical treatment was opted given his symptomatic relief from nerve root and facet joint blocks.

Background: In girls who present with vaginal trauma, sexual abuse is often the primary diagnosis. The differential diagnosis must include patterns and the mechanism of injury that differentiate accidental injuries from inflicted trauma., Case: A 7-year-old prepubertal girl presented to the emergency department with genital bleeding after a serious accidental impaling injury from inline skating. After rapid abduction of the legs and a fall onto the blade of an inline skate this child incurred an impaling genital injury consistent with an accidental mechanism. The dramatic genital injuries when repaired healed with almost imperceptible residual evidence of previous trauma., Summary and Conclusion: To our knowledge, this case report represents the first in the medical literature of an impaling vaginal trauma from an inline skate and describes its clinical and surgical management., (Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

Purpose: The purpose of this study is to report our experience of fractures in children riding Hoverboards., Methods: We undertook a prospective review of all children attending our hospital who sustained fractures whilst riding a Hoverboard. Data such as patient demographics, type of fracture sustained, treatment received, complications and outcome were collected., Results: Twelve children, 5 males and 7 females with ages ranging from 5.5 to 15.3 years were included in this study. All patients sustained upper limb fractures and the distal radius was the commonest fracture site (30%). Surgery was required in 6 (50%) out of the 12 patients because the respective fractures were displaced. No patient had any ongoing complaints or disability at the last clinic review.   Conclusion : Children riding Hoverboards are predisposed to upper limb fractures and parents who purchase Hoverboards should be warned about this.

Objective: Kidney is the most commonly injured organ of the genitourinary tract after trauma. Half of blunt renal injuries are caused by traffic accidents, but sport activities are also included as frequent causes. Skatebording is popular among young people but it deserves being considered a potential cause of severe injuries. A number of published medical reports mainly refer to bone, joint and head injuries but no cases have been reported on urologic or kidney trauma., Methods: We present two cases of renal trauma in adolescent males occurred while doing skateboarding., Results: The first patient had a grade 3 renal trauma with urinary extravasation, managed conservatively with ureteral stenting. The second patient had a grade 4 to 5 renal trauma with cardiovascular instability requiring an urgent nephrectomy., Conclusions: We would emphasize these cases as an emergent urological warning. Scientific information and medical education should be addressed from physicians to a targeted population, in order to reduce among teens the incidence of injuries of such at-risk activity.

We analyzed the US incidence of emergency department (ED) visits and hospitalizations for falls from skiing, snowboarding, skateboarding, roller-skating, and nonmotorized scooters in 2011. The outcome was hospital admission from the ED. The primary analysis compared pediatric patients aged 1 to 17 years to adults aged 18 to 44 years. The analysis used ICD-9 E-codes E885.0 to E885.4 using discharge data from the Nationwide Emergency Department Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. Approximately 214 000 ED visits met study criteria. Skiing injuries had the highest percentage of hospitalizations (3.30% in pediatric patients and 6.65% in adults 18-44 years old). Skateboard and snowboard injuries were more likely to require hospitalization than roller skating injuries in pediatric patients (odds ratio = 2.42; 95% CI = 2.14-2.75 and odds ratio = 1.83; 95% CI =1.55-2.15, respectively). In contrast, skateboard and snowboard injuries were less severe than roller-skating injuries in adults., (© The Author(s) 2015.)

This case report describes a 12-year-old boy, who suffered an injury to the right knee in a skateboard accident. Radiographs and surgery confirmed the extremely rare bifocal avulsion fracture including the distal patellar pole and tibial tuberosity. Open reduction and internal fixation was accomplished, and 4-month follow-up demonstrated a good outcome.

Traumatic extensor dysfunction of the knee in children is a rare injury, with the majority resulting from tibial tubercle avulsion fracture or patellar sleeve fracture. We report a rare case of combined patellar avulsion fracture and tibial tubercle fracture. With open anatomic reduction, both injuries were successfully treated. While many variations of tibial tubercle fracture have been reported, the authors believe this to be the first report in the English-language literature of this particular combined injury to the knee extensor mechanism in an adolescent. Advanced imaging with computed tomography provided vital information to aid with operative planning, especially since the majority of the unossified tubercle was not seen on plain radiographs, and all fracture fragments were originally believed to be from the tibial tubercle. Computed tomography distinguished the patellar fracture from the tibial tubercle fragments, verifying preoperatively the complexity of the injury.

Aim: The aim of this study was to describe trauma in children secondary to the use of wheeled recreational devices (WRDs)., Methods: This study retrospectively described trauma secondary to use of WRDs sustained by children 16 years or younger over a period of 12 months at two tertiary paediatric hospitals in Brisbane, Queensland. Data were analysed from the Paediatric Trauma Registry at these two facilities. Data were also retrieved from The Commission for Children and Young People and Child Guardian to provide information regarding deaths in Queensland from the use of WRDs for the period January 2004 to September 2013. Outcome measures included age, gender, types of injuries, Injury Severity Scores, admission to Intensive Care, and length of hospital stay for all hospital admissions greater than 24 h., Results: A total number of 45 children were admitted with trauma relating to WRDs during the 12 months, representing 5.3% of all trauma admissions of greater than 24 h during this time period. Of these, 34 were male with a median age of 11.0 years (IQR = 9-13). Limbs accounted for the majority (54.5%) of injuries, with other common injuries being spine/cranial fractures (14.5%), lacerations (12.7%), internal organ injuries (9.1%), and intracranial bleeds (9.1%). There were six admissions to the Paediatric Intensive Care Unit and one death., Conclusions: WRDs contribute significantly to injuries sustained by children. A large proportion of these injuries may be preventable, suggesting that mandating the use of protective equipment in Queensland may be of great benefit., (© 2015 The Authors.

Relevant Local Injury Epidemiology: In Ottawa, between 2005 and 2009 there was an annual average of 47.2 head injuries due to ice skating in children and youth (1-19 years of age) requiring a visit to the emergency department, with the highest rates among those aged 5-14 years. Between 2002 and 2007, only 6% of children were wearing a helmet during ice skating when the head injury occurred. During indoor public skating sessions, 93% of children (<10 years)-57% aged 10-12 years, 20% aged 13-17 years and 9% adults-wore helmets in the absence of a policy. Support for a helmet policy was high from public health, medical, political and community perspectives., Best Practice: Helmet policies in relation to cycling have demonstrated increases in helmet use and reduction of head injuries without decreasing physical activity. However, no known studies have examined the effect of indoor ice skating helmet policy coupled with education and promotional activities on helmet use, participation and attitudes towards helmet use., Implementation: An ice skating helmet policy for children (<11 years of age) and those with limited skating experience at indoor rinks during public skating sessions was developed, implemented and evaluated. Supportive activities such as discount coupons, promotional materials, a media launch, social marketing and staff training are described., Discussion: The helmet policy was associated with increased helmet use for young children and for older children, youth and adults not included in the policy, without decreasing attendance to public skating sessions., (Published by the BMJ Publishing Group Limited.

Ice skaters sustain a significant number of head injuries each winter. We are the first to implement an all-ages helmet policy at a university-based Canadian arena. We report our experience from a cross-sectional observational study as well as the policy's consequences on helmet use and skating participation. Educational programming was provided prior to policy implementation. Observations of helmet use, falls and skater demographics were conducted prior to education/implementation and after policy implementation. The number of skaters observed was essentially unchanged by the policy; 361 skaters were observed pre-implementation, while 358 were observed post-implementation during the same number of observation-hours. Pre-implementation, helmet use ranged from 97% among children under 12 to 10% among adults; post-implementation use in all skaters was 99%. Falls were observed among all age groups, with preponderance among those aged 4-12. An all-ages helmet policy was successful both in achieving helmet use among all skaters and in maintaining participation rates., (Published by the BMJ Publishing Group Limited.

Background: Recreational use of small-wheeled vehicles (SWVs), which include skateboards, longboards, nonmotorized scooters, ice skates, and roller skates or rollerblades, results in numerous injuries in the United States., Objective: To describe the nature and severity of traumatic brain injuries (TBIs) that result from the use of SWVs in Utah., Methods: Patients who were admitted to any Utah hospital after a SWV-related injury from 2001 through 2010 were identified from the Utah State Trauma Registry. Patients who sustained TBI were identified by International Classification of Diseases, Ninth Revision, codes., Results: Of 907 patients admitted with SWV injury, 392 (43%) had a TBI (85% male). Their mean age was 19.8 ± 0.5 years, including 234 (60%) aged ≤18 and 119 (30%) aged 19 to 29. Most patients sustained TBI while using a skate- or longboard (87%). Mean Glasgow Coma Scale score in the emergency department was 12.8 ± 0.2. Thirty-nine percent were admitted to an intensive care unit, and 6% (23) underwent emergent neurosurgical intervention. Thirty-three (8.4%) patients had a concussion; the rest had nonoperative intracranial hemorrhage. Among patients for whom helmet use data were available, 8 out of 291 (2.7%) patients with TBI were wearing a helmet, whereas 24 out of 190 (12.6%) non-TBI patients were wearing helmets (P < .001). Overall mortality was higher in TBI patients than in non-TBI patients (2.3% vs 0.2%, P = .003)., Conclusion: Young people, especially males, who ride SWVs in Utah are at risk for serious TBI, admission to the intensive care unit, neurosurgical intervention, and death. Helmet use in these patients is likely rare, but may reduce the risk of TBI and death., Abbreviations: ED, emergency departmentSWV, small-wheeled vehicleTBI, traumatic brain injury.

This in-depth literature review shows that skateboarding has experienced intermittent periods of popularity, with an estimated 6-15 million skateboarders in the US currently involved at all levels of recreational play and competition. Head trauma accounts for ∼ 3.5-13.1% of all skateboarding injuries. Injury occurs most often to the upper extremity (55-63%), whereas thoracoabdominal and spine injuries account for 1.5-2.9% of all trauma and lower extremity injuries occur 17-26% of the time. Few fatal injuries (1.1%) have been reported, oftentimes resulting from traumatic head injuries incurred from collisions with motor vehicles. Although skateparks may be perceived as a safer alternative to street skateboarding, injuries still occur when the skateboarder collides with an object or falls from the board. Factors leading to trauma include fatigue and overuse, age and skill level, inadequate medical care, environmental conditions, equipment concerns, lack of fitness and training, and the detrimental behavior of the competitor. Although not all skateboarding injuries are avoidable, numerous opportunities exist to instill safety involving education, instruction, and supervision and the proper use of protective gear to reduce predisposition to trauma. Future research recommendations include a more standardized data collection system, as well as an increased focus on kinetic analysis of the sport. Legislation involving helmet laws and the increased investment in a safer environment for the skateboarder may also assist in reducing injury in this sport.

Several facets of figure skating, such as the forces associated with jumping and landing, have been evaluated, but a comprehensive biomechanical understanding of the cranial forces associated with spinning has yet to be explored. The purpose of this case study was to quantify the cranial rotational acceleration forces generated during spinning elements. This case report was an observational, biomechanical analysis of a healthy, senior-level, female figure skating athlete who is part of an on-going study. A triaxial accelerometer recorded the gravitational forces (G) during seven different spinning elements. Our results found that the layback spin generated significant cranial force and these forces were greater than any of the other spin elements recorded. These forces led to physical findings of ruptured capillaries, dizziness, and headaches in our participant.

Muscle rupture is rarely treated surgically. Few reports of good outcomes after muscular suture have been published. Usually, muscular lesions or partial ruptures heal with few side effects or result in total recovery. We report a case of an athlete who was treated surgically to repair a total muscular rupture in the pectoralis major muscle. After 6 months, the athlete returned to competitive practice. After a 2-year follow-up, the athlete still competes in skateboard championships., (2015 BMJ Publishing Group Ltd.)
