Registration of cruciate ligament injuries in Norwegian top level team handball. A prospective study covering two seasons

All cruciate ligament injuries in the three upper divisions for men and women (3392 players) in Norwegian team handball in the 1989-90 and 1990–91 seasons were registered. A questionnaire was mailed to all injured players. Ninety-three cruciate ligament injuries were registered; 87 in the anterior cruciate ligament (ACL), and six in the posterior cruciate ligament (PCL). Among women, 1.8% were injured compared with 1.0% of the men. In the first division, the risk of being injured was considerably higher: 4.5% of the players had a cruciate ligament injury. There were 0.97 cruciate ligament injuries per 1000 playing hours in the three divisions taken together. Seventy-five per cent of the injuries occurred during games. Ninety-five per cent involved no contact between players. Activities in which the friction between shoe and floor was significant caused 55% of the injuries. Injuries caused by running into another player contributed to only 5% of the injuries. No significant differences were observed in injury incidence during matches between different types of floors (parquet, Pulastic and other synthetic sufaces).     

Soccer injuries among youth

This study reports the quantitative and qualitative aspects of sports injuries in a 5-day youth soccer tournament with 12,907 players. A total of 132 injuries that resulted in at least one days' absence from soccer playing were of special interest. The overall injury rate was 3.6 for boys and 4.4 injuries per 1000 hours of play for girls. Statistically significantly higher injury rates between players in puberty and differences in type and location of injuries between boys and girls were found. In 77% of the cases, the injury happened while the injured player was in physical contact with another player, 59% had ball contact and 7% had no contact with any person or ball at all. Five months later a questionnaire was send out to the serious injured players. Of 85 injured players, 10 were absent from school or work on average 11.5 days. Five had surgery. Injury prophylaxis in soccer tournaments is proposed.     

Epidemiology of badminton injuries

In the badminton season 1983/1984, a prospective injury registration was done in 375 randomly chosen elite and recreational badminton players, of whom 81% could be followed. We found 257 injuries: an incidence of 2.9 injuries/player/1000 badminton hours. Men were more frequently injured than women. The prevalence was 0.3 injury per player. It was highest in men, and there was no difference between elite and recreational badminton players; 92% of the injured were playing with their injury. The pathophysiology was overuse in 74% (169/229), strains in 12% (28/229), sprains in 11% (26/229), and fractures in 1.5% (3/229). Possibilities for reducing the number of injuries and their severity are increased injury information to players and trainers and the introduction of stretching all involved muscle groups.     

An epidemiologic and traumatologic study of injuries in handball

To identify the risk factors of injuries in handball, 221 players were followed during one indoor season. The injury incidence was 4.6/1000 playing hours and 11.4/1000 game hours. The upper extremity was involved in 41% of the injuries including 21% finger sprains. Ankle sprains were the most common injury (33%), and overuse injuries accounted for 18%. The risk of reinjury was 32%. Contact with opponent players during running or shooting caused 31% of the injuries. Errors during grasping the ball were the reason for most of the finger injuries. Forty percent of the injuries was treated by the players themselves. After the injury 73% were absent from handball for more than 1 week. Forty-one percent of the injured players had complaints 6 months after the end of the season. The study shows that injuries in handball are serious and cause extensive consequences for the players. In most of the injuries both intrinsic and extrinsic factors were involved, and prophylactic intervention in these cases demands changes in more fields.     

Beach handball is safer than indoor team handball: injury rates during the 2017 European Beach Handball Championships

Purpose

Beach handball is a relatively new type of sports, which was derived from team handball. Medical issues such as frequency and severity of injury are yet unknown. The purpose of this study was to investigate the injury pattern and injury rates of this new type of sports.

Methods

This study investigated the injury incidence of 30 national teams (10 senior and 20 u-17 teams, 16 men’s and 14 women’s teams) participating in the 2017 European Beach Handball Championships. Reports on injuries sustained during the senior and u-17 youth tournaments were provided by the medical staff of each team. Injury incidence was differentiated between age and sex, and between the five field positions (goalkeeper, wing, central defender, pivot, and specialist).

Results

During the tournaments, 87 injuries were recorded yielding an overall injury incidence of 286.1 per 1000 match hours. Time-loss due to injury was 49.3 per 1000 match hours. Senior players had a higher overall injury incidence with 395.3 injuries than u-17 players with 205.7 injuries per 1000 h match hours (p?<?0.01). Comparison of the injury incidence between the two sexes showed 330.23 injuries per 1000 h handball exposure for male players and 234.9 injuries for female players (n.s.). The most frequent injury type was sprains (21 injuries, 24.1%) followed by contusions (19 injuries, 21.8%) and skin abrasions with (15 injuries, 17.2%). Central defenders and specialists had the highest injury incidence. Thighs, ankles, as well as foot and toes (altogether 12 injuries, all 13.8%) were the three most frequently injured anatomic sites.

Conclusions

Beach handball seems to have a lower incidence of time-loss injuries than that reported for indoor team handball. This study is an important basis for developing injury prevention strategies in this sports that should focus on thighs, ankles, feet and toes. Further research into this new type of sports is essential to identify risk factors and to develop adequate injury prevention measures.

Injuries in young female players in European team handball

The purpose of this study was to examine the nature, extent and severity of sports injuries in young female players in European team handball and to identify the etiological factors involved in the injuries. Twenty-two teams with 217 players, aged 16–18 years, participated in the study. A very high injury incidence during games was observed, with 40.7 injuries/1000 hours of game. Backplayers had the highest incidence (54.8/1000 hours), which is five times higher than any previously recorded injury incidence in players in European team handball. We found that 92.9% of injuries were traumatic and 7.1% were from overuse. One-hundred and twenty-four of the 211 injuries were traumatic injuries of the lower extremities. Of these 63 (51%) were without contact with an opponent. The study confirmed that European tesm handball is a sport that has a very high injury rate, especially regarding young female players. Field position and earlier injuries are major risk factors, with an earlier injury being the single highest risk factor and with backplayers having a significantly higher number of injuries than players in other field positions.     

Community level australian football: a profile of injuries

Identification of injuries and their risk factors is required in order to develop risk controls within the context of sports injury prevention. The Australian Football Injury Prevention Project (AFIPP) was a randomised controlled trial (RCT) examining the effects of protective equipment on injury rates in Australian Rules Football. The aim of this paper is to describe the general injury profile of community level Australian Football players over one season, as recorded during this RCT. Players were recruited from the largest community football league in Victoria, Australia, during the 2001 playing season. A total of 301 players participated (64% response rate) and all injuries occurring during training and games were recorded. The overall injury incidence rate was 12.1/1000 player hours. Bruises/soft tissue injuries made up more than a quarter of all injuries (28%) and the leg (lower leg, ankle, thigh/hamstring and knee) was the most commonly injured body region. Most injuries occurred at the beginning of the season (April-May, 53% of injuries), during competition (77%) and through body contact (49.9%). Midfielders (OR = 3.39, 95% CI: 1.13, 10.14) and players aged at least 25 years (OR = 2.15, 95% CI: 1.06, 4.34) were significantly more likely to experience an injury than other playing positions and younger players. Although the injury rate in this study was lower than that in previous studies, the results are consistent with the finding that injuries tend to occur earlier in the season and more commonly during competition. Injury prevention efforts should be particularly targeted at midfielders and older players.     

Sports injuries in adolescents' ball games: soccer, handball and basketball.

In a prospective study of 302 adolescent players in three ball games (soccer, handball and basketball), 119 incurred injuries. The injury incidence (number of injuries per 1000 playing hours) was 5.6 in soccer, 4.1 in handball and 3.0 in basketball. Ankle sprains accounted for 25 per cent of the injuries, finger sprains 32 per cent, strains in the thigh and leg 10 per cent, and tendinitis/apophysitis 12 per cent. The most serious injuries were four fractures, one anterior cruciate ligament rupture, and two meniscus lesions. The most serious injuries, with the longest rehabilitation period, occurred in soccer. In soccer, many injuries occurred during tackling and contact with an opposing player, while the injuries in handball and basketball were often caused by ball contact and running.     

Prevalence and variance of shoulder injuries in elite collegiate football players

BACKGROUND: Shoulder injuries are the fourth most common musculoskeletal injury encountered in American football players. There is little information in the literature on the role of playing position in the type of shoulder injuries seen. HYPOTHESIS: There is a high prevalence of shoulder injuries in elite collegiate American football players, with type of injury varying by playing position. STUDY DESIGN: Cohort study (prevalence); Level of evidence, 3. METHODS: A total of 336 elite collegiate American football players were invited to the National Football League Combine for physical testing and medical evaluation. Current and historical data were evaluated for the purpose of this study, and all players underwent radiographic examinations, including plain radiographs and/or magnetic resonance imaging when necessary. All shoulder pathological conditions and shoulder surgical procedures were recorded. Players were categorized by position for the analysis of position-specific trends. RESULTS: Of the players, 50% had a history of shoulder injuries, with a total of 226 shoulder injuries (1.3 injuries per player injured); 56 players (34%) had a total of 73 surgeries. The most common injuries were acromioclavicular separation (41%), anterior instability (20%), rotator cuff injury (12%), clavicle fracture (4%), and posterior instability (4%). The most common surgeries performed were anterior instability reconstruction (48%), Mumford/Weaver-Dunn surgery (15%), posterior instability surgery (10%), and rotator cuff surgery (10%). Shoulder injuries were more common in quarterbacks and defensive backs. Surgery was more common in linebackers or linemen. A history of anterior instability was more common in defensive players, with surgery required 76% of the time. Linemen had more rotator cuff injuries and posterior instability than players in other positions. CONCLUSION: Shoulder injuries are common injuries in elite collegiate football players, with one-third undergoing surgical procedures. There are definitive trends in the types of injuries per player position.     

Handball injuries during major international tournaments

BACKGROUND: Several authors have analyzed the incidence of handball injuries in amateur players but information of handball injury in top-level players is very limited. The aim of the study was to analyze the incidence, circumstances and characteristics of handball injuries during major international tournaments. METHODS: Injuries during six international handball tournaments were analyzed, using an established injury report system. The physicians of all participating teams were asked to report all injuries after each match on a standardized injury report form. The response rate was on average 87%. RESULTS: The incidence of injury was on average 108 injuries/1000 player hours (95% confidence interval (CI): 98-117) or 1.5 injuries/match (95% CI: 1.4-1.6). The injuries affected most frequently the lower extremity (42%), followed by injuries of the head (23%), upper extremity (18%) and trunk (14%). The most frequent diagnosis was contusion of head (14%) or ankle sprain (8%). The majority of injuries were caused by contact with another player. The incidence of time loss injuries was on average 27/1000 player hours (95% CI: 22-32), and significantly higher in men than in women. CONCLUSION: Preventive program proven effective should be implemented. Fair Play is an essential aspect of injury prevention. Therefore, close cooperation with the referees is also necessary to make handball a safer sport.     

A pooled data analysis of injury incidence in rugby league football

OBJECTIVE: The aim of this study was to summarise the injury rates in professional rugby league football. METHODS: Previously published studies were identified from database searches of the literature from Medline, Sports Discus and Web of Science. A total of 18 articles, which reported the prospective injury data collection for at least one playing season in professional rugby league worldwide, were included. The definition of injury adopted required an injured player to miss the subsequent game through injury. Ten studies satisfied the injury definition criteria for inclusion. A review of articles and extraction of relevant data were carried out independently by two authors. RESULTS: A total of 517 injuries were reported during 12819 hours of exposure (753 games), which resulted in an overall injury rate of 40.3 injuries per 1000 hours [95% confidence interval (CI) 36.9 to 43.8]. Most injuries were to the lower half of the body (20.7 per 1000 hours, 95% CI 17.7 to 24), with the trunk receiving the least (6.7 per 1000 hours, 95% CI 5 to 8.6). CONCLUSIONS: Injury rates in professional rugby league are higher than in some other contact sports, probably because of the large number of physical collisions that take place. This pooled data analysis provides more accurate estimates of injury incidence in the game of professional rugby league football.     

Incidence of injuries in the New Zealand national rugby league sevens tournament

This study investigated the incidence, site, nature and causes of injuries sustained in the New Zealand national rugby league sevens tournament. A total of 218 players competing in 47 matches were studied. All injuries sustained within the tournament were prospectively recorded. Injuries were categorised according to the severity assessment at the time of the injury. Information obtained included the time, site, nature and cause of the injury. The incidence of injury was 497.6 per 1000 playing hours. More than 40% (216.1 per 1000) of injuries sustained occurred within the lower limbs. The shoulder was the single most commonly injured site (78.6 per 1000). Sprains were the most common injury type (189.9 per 1000). The ball-carrier sustained significantly more (p<0.05) injuries than the tackling player (216.1 per 1000 [43.4%] versus 117.8 per 1000 [23.7%]). There were significantly more injuries on the first day of competition than on the second day of competition (600.4 per 1000 [76.3%] versus 320.9 per 1000 [23.7%]). The findings of higher injury rates on the first day of competition and during the second period of matches suggest that playing intensity and player fatigue may contribute to injuries in rugby league sevens.     

The incidence of head/neck/orofacial injuries in non-elite Australian Football

Injuries to the head/neck/orofacial region are common in contact and collision sports such as Australian Football. A total of 294 players who did not wear headgear from 23 teams from a large metropolitan community football league in Victoria, Australia, were monitored for head/neck/orofacial injuries over one playing season. This short report describes the incidence of head/neck/orofacial injuries in this cohort. Overall, there were 37 head/neck/orofacial injuries reported at a rate of 2.6 injuries/1000 participation hours. Over 70% of these were the result of being struck by another player through inadvertent contact during competitive play. Facial lacerations were most common (0.97/1000 player hours), followed by concussion (0.49/1000 player hours). Nine of the cases were referred to hospital for further treatment.     

Pattern of injury in handball and comparison of injured versus noninjured handball players

A questionnaire was sent to 300 members (at random) of the Dutch Handball Association (response: 76%) (1) to study the injuries involved in handball and the resulting medical attention and (2) to compare injured versus non-injured players with respect to sex, age, somatotype, and sports participation. Group A was defined as players taking part in handball only (62%); 38% also regularly took part in other sports (group B). The male/female ratio in group B was approximately 4 times larger than in group A. The results showed that 51% of all players sustained at least one injury during handball in 1 year. The ratio of injuries/all players in our study did not differ much from the level in a comparable Danish study, 0.82 and 0.71, respectively. Nearly 60% of all handball injuries were localized in the lower compared with only 30% in the upper extremities. A general practitioner was consulted in nearly 40% of the injuries. Within group A, relatively more males were injured and also more frequently compared with females. Injuries in females did not differ from all injuries with respect to localization and medical attention. After comparison of injured versus noninjured players, we conclude that the role of somatotype is not elucidated and that sex and the number of sports might play an important role in the etiology of handball injuries, whereas age is only of minor importance.     

Epidemiology and traumatology of injuries in elite soccer: a prospective study in Finland

A prospective study of male soccer injuries among 12 teams playing at the highest competition level was carried out in Finland in 1993. Overall, two out of three players were injured during the whole season. The injury incidence per 1000 playing hours among injured players and all players during games was higher than during practice, 14.2 vs. 11.3 and 2.3 vs. 1.8, respectively. The lower extremity was involved in 76% of the injuries. Thigh injuries were most frequent (22%), whereas overuse injuries were scarce (6%). Eighteen per cent of the injured players needed surgery and in most cases (58%) the reason for surgery was a knee injury. Sixteen per cent of all injured players were absent from soccer for more than 1 month after the injury. The mean absence time was 17 days for all and 84 days for operatively treated players.     

Incidence of injury in amateur rugby league sevens

OBJECTIVES: To investigate the incidence, site, and nature of injuries sustained in amateur rugby league sevens tournaments. METHODS: A total of 168 players competing in three amateur rugby league sevens tournaments were studied. All injuries sustained during matches were recorded. Information recorded included the name of the injured player and the time, cause, anatomical site, and nature of the injury. RESULTS: The incidence of injury was 283.5 per 1000 playing hours. Some 40% (113.4 per 1000 playing hours) of all injuries sustained were to the lower limb (chi(2) = 5.3, df = 1, p<0.05). Contusions were the most common type of injury (113.4 per 1000 hours, 40%, chi(2) = 9.5, df = 4, p<0.05), with most (198.4 per 1000 hours, 70%, chi(2) = 31.5, df =4, p<0.001) occurring in physical collisions and tackles. An increasing injury incidence was observed over the first (99.2 per 1000 hours), second (198.4 per 1000 hours), third (347.2 per 1000 hours), and fourth (694.4 per 1000 hours) matches played during the tournaments (chi(2) = 9.2, df = 3, p<0.05). CONCLUSIONS: The results of this study suggest that amateur rugby league sevens tournaments, which require players to compete repeatedly on the same day, may hasten the onset of fatigue and predispose to injury.     

Injuries among male and female elite football players

All 12 female football clubs (228 players) and 11 of 14 male clubs (239 players) in the Swedish premier league were followed prospectively during the 2005 season. Individual exposure (playing time), injuries (time loss), and injury severity (days lost due to injury) were recorded by the team medical staffs. Injury incidence was higher for male players during both training (4.7 vs 3.8 injuries/1000 h, P=0.018) and match play (28.1 vs 16.1, P<0.001). However, no difference was found in the incidence of severe injury (absence >4 weeks) (0.7/1000 h in both groups). The thigh, especially the hamstrings, was the overall most commonly injured region in both sexes, while the hip/groin was more commonly injured in male players and the knee in female players. Knee ligament injuries accounted for 31% and 37% of the total time lost from football for male and female players, respectively. In conclusion, male elite players had a higher injury incidence than their female counterparts although no difference was observed in the incidence of moderate to severe injury. We recommend that preventive measures should be focused on hamstring and knee ligament injury in order to reduce the overall injury burden.     

Prevention of injuries in young female players in European team handball. A prospective intervention study

Young female players in European handball have a very high injury incidence, up to 50 injuries per 1000 hours of game. More than half of these injuries happen without any external cause. The aim of the study was to investigate the effect of an intervention programme designed to reduce the number of injuries in young female players in European handball, with special emphasis on injuries in the lower extremities. The programme was created using elite athlete training programmes and those designed for rehabilitation of injured athletes with functional instability of their ankles and rupture of the anterior cruciate ligament. It included the use of an ankle disk for 10–15 min at all practice sessions, for one 10-month season (August 1995-May 1996). Twenty-two teams participated in the study, and were randomly assigned to the intervention or control group. Eleven teams with 111 players were randomised to the intervention group and 11 teams with 126 players to the control group. Data were analysed using a t -test for continuous variables, chi²-analysis and Fisher's exact test for dichotomous variables and multivariate methods to determine odds-ratios. The results indicated that using the intervention programme decreased the numbers of both traumatic and overuse injuries significantly. The differences in injuries between the groups were 80% during games and 71% during practice. In addition, the players in the control group had a 5.9 times higher risk of acquiring an injury than the players in the intervention group.     

Epidemiology of injuries in Australian junior rugby league players

ObjectivesConduct a large-scale epidemiological study of injury characteristics (location, type, mechanism, severity, burden) and incidence in community junior rugby league.DesignProspective cohort epidemiology study.MethodsInjury surveillance was conducted in three district leagues (Penrith, Canberra, Melbourne) in under 6 (U6) to under 18 years (U18) age groups across the 2016 season. Club sports trainers recorded all match/training medical-attention injuries using a commercial electronic application which recorded injury circumstances and characteristics.ResultsA total of 13,169 players from 897 teams participated and 408 (89% male) players sustained 485 injuries, 94% of which were match related. The overall injury incidence was 5.9 injuries/1000 player hours and highest in U13–U18 female players (22.2 injuries/1000 player hours). The mean injury severity of 16 ± 31 days missed training/match-play caused an overall injury burden of 94.2 days missed/1000 player hours). Tackles accounted for 84% of injuries. Joint and contusion injuries were the most prevalent injury type and the head (35% total injuries, primarily bruising and bleeding) was the most injured body site.ConclusionsThis is the first study to report injuries across a large cohort of all-age Australian community junior rugby league players over one season. Injury prevalence was lower than previously reported in junior rugby league suggesting the sport has not become more dangerous for junior players. These findings provide an evidence-base to inform or revise policy, training and injury prevention programs and athlete development pathways in relation to game-wide safety and develop best-practice protocols in injury management for rugby league athlete support personnel.
