The socioeconomic consequences of sports injuries in Randers, Denmark

Prospective epidemiologic data on all sports injuries were collected in a casualty ward for 1 year in a well defined geographical area with 124,321 inhabitants. A total of 1839 sports injuries were registered; 1535 (83%) of those injured completed questionnaires covering the sports, economic and social consequences of the sports injury. The incidence of sports injury was 61 per 1000 active sports players per year and 15 per 1000 inhabitants in the catchment population per year. The injuries resulted in an average sick leave from work of 3 d and 4 weeks out of competition and training; 16% had chronic health problems 2 years after injury and, unexpectedly, as many as 7% stopped participating in sports. The total net loss of income was DKK 147,900 (USD 23,000), an average of DKK 1781 (USD 270) for each person who had a financial loss. Abbreviated Injury Scale scores, hospitalization rates and inpatient time were correlated.     

Medical treatment and costs of sports-related injuries in a total population

A prospective study of acute injuries from sports and physical exercise was carried out during 1 year in a total population of a municipality with 31,620 inhabitants. The medical treatment and the services required for the injuries have been calculated and related to the total consumption of medical care in the municipality. A total of 571 injuries (17% of all injuries) occurred in 28 different sports: 65% of the injured were males. Sports injuries accounted for 3% of all acute visits and there were altogether 1,083 outpatient visits, which yields a mean of 1.9 visits per injury. Related to the total consumption of outpatient visits to the five clinics in the municipality sports injuries also accounted for 3%. Forty-four patients were hospitalized; the proportion of inpatient care due to sports injuries was 0.7% and the mean length of stay in hospital 3.9 days. The total amount of sick leave compensated for sports injuries (3,477 days) was 1.2% of all days compensated in 1984. The overall mean cost per injury was US$ 335. Individual sports (motorcycling, downhill skiing and equine sport) were by far the most costly in the Falk?ping survey, the dearest of the team sports ranking only fifth (handball followed by soccer).     

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.     

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.     

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.     

Injury pattern in youth team handball: a comparison of two prospective registration methods

The purpose of this study was to examine the injury incidence and pattern of injuries in youth female and male team handball players using two different prospective registration methods; match reports (90 teams, 1080 players) and coach reports (34 teams, 428 players). A total of 118 injuries were recorded by the coach report, of which 93 (79%) were acute injuries (incidence training: 0.9+/-0.16 injuries/1000 player hours; matches: 9.9+/-1.26; rate ratio vs training: 10.8 [95% confidence interval (CI) 7.0-16.6]; P<0.0001) and 25 (21%) were overuse injuries. Knee (26%) and ankle (24%) injuries accounted for half of the acute injuries (training: 0.5+/-0.12 injuries/1000/h; matches: 4.4+/-0.84; rate ratio vs training: 8.0 (95% CI 4.5-14.5); P<0.0001). No gender difference was found in the injury rate (rate ratio female vs male: 1.3 (95% CI 0.8-2.1); P=0.40). Most of the injuries occurred in the attacking phase by back or wing players doing a plant-and-cut, landing or turning movement, and more than half in contact situations with the opponent. Similar results were observed for acute match injuries in the match report. These results indicate that the rate of injuries in youth team handball is as high as at the senior level, and prevention should focus on knee and ankle injuries. The coach report seems to be the best method to register injuries in youth team handball to provide a full spectrum of injuries according to their type, incidence and severity.     

Does a major knee injury definitely sideline an elite soccer player?

Injuries occurring in three Swedish elite soccer teams were analyzed during 1 year. A total of 49 of 64 players (75%) sustained 85 injuries. The incidence of injury during games was 13 injuries per 1000 hours, while the incidence during training was 3 injuries per 1000 hours. Twenty percent of the injuries required hospital facilities. The majority of the traumatic injuries (93%) were to the lower extremities, with one third of the total injuries occurring in the knee. Overuse injuries accounted for 35% of all injuries and occurred mainly during preseason training and at the end of each season. Conversely, the majority of traumatic injuries occurred during games, equally distributed between the first and second halves with a predominance toward the end of each half. The position of the player within the team did not influence injury rate. The referee considered 28% of the traumatic injuries to be caused by violation of existing rules. Thirty-four percent of the injuries were major, causing more than 1 month of absence from training and/or games. Eleven knee injuries required surgical intervention revealing seven ruptured ACLs, of which three were chronic. At followup, 9 to 18.5 months after injury, 4 of 12 players with major knee injuries had returned to play at the elite level. The others had either been transferred to lower divisions or were still in rehabilitation.     

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.     

Injuries among young soccer players

We registered all new injuries among 496 male youth soccer players, aged 12 to 18 years, during the course of one year. The incidence of injury was 3.7 injuries per 1000 hours of soccer per player. The incidence increased with age, and at the higher ages within the youth players, approached the incidence rate of senior players (age greater than or equal to 18 years). Seventy percent of the injuries were located in the lower extremities, particularly the knee (26%) and ankle (23%). Back pain occurred in 14% of players. Fractures, which accounted for 4% of injuries, were most often in the upper extremities. We conclude that youth soccer is a relatively low-risk sport with an injury pattern that differs slightly from that of senior players.     

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).     

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.     

Epidemiology of injuries in typical Scandinavian team sports

An investigation by questionnaire was undertaken in a group of 480 football players and 288 handball players (768 players). Of these 803 were injured, giving a player incidence of 4.1 injury/1000 football hours and 8.3 injury/1000 handball hours. The lower extremities were involved in 82% of the football injuries, whereas handball injuries were evenly distributed on both upper and lower extremities. The football injury prevalence was 0.36 per player, the handball injury prevalence 0.71 per player. Medical attention was given to 62% of the injured footballers and 47% of the injured handballers. Based on the injury pattern, some modifications to the rules and equipment in the two sports is suggested: The "boot-type" footwear should be tried out, and the soles in both games should correspond to the different playing surfaces that may be encountered. Stricter enforcement of the rules, and the use of a maximum size playing ground in both sports. Last, but not least a modification of the football rules concerning substitution is a must.     

Neuromuscular exercises prevent severe knee injury in adolescent team handball players

Purpose

Team handball is associated with a high risk of severe knee injury that needs to be reduced, particularly at the youth level. The purpose of this study was to show how an injury-prevention programme effectively reduces severe knee injury in adolescent team handball players.

Methods

Of 23 adolescent handball teams of both sexes, 13 were randomly allocated into the intervention group (168 players) and 10 into the control group (111 players). Players of the intervention group regularly participated in an injury-prevention programme for one season. Handball exposure and sustained injuries were documented for both groups on a monthly basis. The primary outcome parameter of the injury-prevention programme was the incidence of severe knee injury.

Results

Of the 279 included players, 68 (24%) sustained 82 injuries yielding an overall incidence of 1.85 injuries per 1000 h handball exposure (intervention group: 50 injuries/incidence: 1.90/1000 h; control group: 32 injuries/incidence: 1.78/1000 h). Knee injury was the second most frequent injury in adolescent team handball. The primary outcome parameter, severe knee injury occurred significantly more often in the control group [mean age (SD) 15.1 (1.0), injury incidence 0.33/1000 h] than in the intervention group [mean age (SD) 14.9 (0.9), injury incidence 0.04/1000 h]. The odds ratio was 0.11 (95% CI 0.01–0.90), p?=?0.019. Other injuries to the lower extremities showed no significant difference between the two groups.

Conclusions

Frequent neuromuscular exercises prevent severe knee injury in adolescent team handball players and should thus be included in the practical routine as well as in the education of team coaches.

     

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.     

Volleyball injuries presenting in casualty: a prospective study.

During 1986, all sports injuries (n = 5222) were prospectively recorded at the two casualty departments in Arhus, Denmark. Volleyball injuries (n = 278) accounted for 5.3% of all sports injuries. An evaluation of the rehabilitation period and the consequences of the injuries was undertaken by questionnaire three years after the injury. The injury incidence was 1.9 injuries/1000 inhabitants/year. Hand, finger, and ankle sprains were the most frequent injuries. Female players had significantly more hand/finger injuries than male players, who incurred more ankle/foot injuries. Knee (6%) and ankle injuries (31%) were responsible for the longest duration of absence from sports participation. There were relatively few chronic injuries. The study suggests the need to enhance prophylactic measures with regard to blocking and overhand pass techniques, in order to reduce the number and extent of ankle and hand/finger injuries.     

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.

Incidence rate of injuries during sport activity and physical exercise in a rural Swedish municipality: incidence rates in 17 sports

A prospective study of acute injuries from sports and physical exercise was carried out during 1 year in a total population of a municipality with 31,620 inhabitants. Data on exposure were collected: the number of participants in each sport, the hours of participation, and number of weeks in the season per year. The number of injuries was used as numerator and the exposure data as denominator in a formula modified from Chambers for the calculation of population at risk in sports. A total of 571 injuries occurred in 28 different sports: 65% of the injured were males. The majority of the injuries were from soccer: 50% of the males and 27% of the females. Incidence rates in 17 sports are presented. The ranking order differs, when calculating not only the number, but also the exposure. Ice hockey and handball were then found to have the highest risk followed by soccer. Team and contact sports on the whole had the highest rates in both genders. As a group, intercompany players had the highest rate, especially in soccer. The lowest rates were found in individual sports such as downhill skiing, horseback riding, racket sports, and running. Gymnastics, except in school physical education, had no injuries at all. Sprains and strains were diagnosed in nearly half of the cases and the foot and ankle were the most frequent sites. Preventive measures are proposed.     

The epidemiology of knee injuries in Iranian male professional soccer players

Detailed injury epidemiology is an invaluable tool for minimising risk associated with sporting injuries. The aim of this study was to investigate epidemiology of knee injuries in Iranian male professional soccer players. In total, 390 soccer players of 16 clubs were studied during one season. A total of 43 injured soccer players were interviewed and 16 team physicians were consulted. All information was collected through standard questionnaires. Furthermore, medical personal prospectively reported time-loss injuries sustained by players over one season and the knee injuries were evaluated. The results showed that in total, from 390 players, 43 of them suffered knee injuries (14.9 per 100 players). The anterior cruciate ligament was the most commonly injured ligament of the knee, in which 12.5% were accompanied by injuries to the medial meniscus and medial collateral ligament. There was a significant difference in incidence of injury between the preferred (62.9%) and non-preferred leg (37.1%). Most injuries were characteristically severe (82.3%). Most injuries occurred in away games (52.94%), mostly in the second half and most commonly in the final 15 min (35.3%). The incidence of non-contact injuries (66.12%) was significantly higher than contact injuries (33.87%). It can be concluded that the incidence of knee injury was high (0.12 injuries per team per match). Injury tends to be more common in match play and mostly at the end of season. Midfielders suffered more knee injuries. Most injuries occurred in the losing teams.     

Injuries in Norwegian female elite soccer: a prospective one-season cohort study

Female soccer has become increasingly popular during the last two decades. According to the International Football Association (FIFA) there are approximately 40 million registered female soccer players in the world. Three studies in elite soccer have shown an injury incidence during games ranging from 12.6 to 23.3 injuries per 1,000 h. A very high incidence of ACL-injuries ranging from 0.31 to 2.2 per 1,000 game hours has also been shown. We followed the Norwegian female elite series during the 2001 season to estimate the incidence and characteristics of injuries. A total of 181 female soccer players on ten teams were followed during the 2001 elite season in Norway. We recorded baseline data, match and training exposure and injury data as type of injury, location and severity of injury. The mean age of the players was 23 years (range 17–34). A total of 189 injuries were recorded and 19 (10%) of these were overuse injuries; 89 (47%) occurred during games and 100 (53%) during training sessions. The incidence of acute injuries was 23.6 per 1,000 game hours and 3.1 per 1,000 training hours. The majority of the injuries occurred in the lower extremities (81%), but there were also a significant number of head injuries (6.3%). The most common injury type was ankle sprain (17.2%). Half of the injuries were minor, with training or game absence of less than 7 days. Midfielders sustained the most injuries (32.6%) with an incidence of 42.4 per 1,000 game hours. We recorded two ACL-injuries and two PCL-injuries during the season. They all occurred during games, and the incidence was therefore calculated to 0.6 per 1,000 game hours for both injury types. The incidences of injuries reported for female soccer varies considerably, with the highest numbers reported from Germany and the present study. These studies have also the highest incidence of minor injuries registered. The location of the injuries is quite similar compared to other reports, but the number of ankle sprains seems to be higher in our study, whereas the number of knee and thigh injuries is lower. There has been much attention to ACL injuries in team handball and hamstring injuries in soccer in Norway, and this could have influenced the team’s pre-season training, resulting in a reduction in the incidence of these injury types. The high number of ankle injuries has to be addressed to see whether this is a result of inadequate rehabilitation routines leading to re-injuries, or other factors. The high number of ACL-injuries in these reports is alarming and needs special attention in the future.     

Air medical evacuations of soldiers due to oral-facial disease and injuries, Operations Enduring Freedom/Iraqi Freedom

This retrospective study was conducted to assess the nature and causes of serious oral-facial illnesses and injuries among U.S. Army personnel deployed to Iraq and Afghanistan in 2003 and 2004. Information for this study came from the U.S. Air Force Transportation Regulating and Command & Control Evacuation System database for medical evacuations (MEDEVACS) for 2003 to 2004. The study found 327 oral-facial MEDEVACS out of Iraq (cumulative incidence: 11/10,000 soldiers per year) and 47 out of Afghanistan (cumulative incidence: 21/10,000 soldiers per year), for a total of 374 MEDEVACS. Forty-two percent (n = 158) of all oral-facial MEDEVACS were due to diseases of the oral cavity, salivary glands, and jaw. Another 36% (n = 136) of oral-facial MEDEVACS were for battle injuries, primarily fractures of the mandible, caused by acts of war. Twenty-one percent (n = 80) of oral-facial MEDEVACS were due to nonbattle injuries, primarily fractures of the mandible, mainly caused by motor vehicle accidents and fighting.
