Eye injury in sport

Eye injury sustained during sport is increasing in incidence worldwide, reflecting the rise in popularity of sport as recreation. It can account for up to 25% of severe eye injuries. This paper considers the historical context and demography of sports injuries, and the physical mechanisms and results of various types of ocular trauma in relation to sport. It reviews the specific problems associated with the sports considered to be most important in the epidemiology of eye injuries today. Certain sports, such as boxing, have an intrinsic risk of injury so high that some consider the sport should be banned. The risk of injury in many sports can be mitigated by changes in rules, such as the prevention of high sticking in ice hockey. Other sports with high risk of trauma could be made far safer with the widespread introduction of eye protection, and this applies especially to squash and badminton. The various types of eye protection are discussed. There is an urgent need to increase awareness of the risk of eye injury, to teach safe techniques, and to encourage the use of appropriate ocular protective wear in those at high risk of injury, especially the one-eyed.     

Injuries in badminton

Though badminton is one of the most widely played sports in the world, it has received little sports medical interest. Based on the few existing studies on injuries in badminton, compared to other sports it is of relatively low risk and dominated by overuse injuries. The injury duration is relatively long, but only a few working days are lost. Anatomically, most injuries are localised to the foot and ankle. The single most frequent injuries are Achilles tendinitis and tennis elbow. Rupture of the Achilles tendon is a rare injury, which is typically seen in older recreational players. When the time of exposure is taken into account men are found to have a higher injury risk than women, and recreational players a higher injury risk than elite players. In contrast to most other sports the relative injury risk is higher during training than in competition. Based on suggested causes of injury and injury mechanisms, together with the known injury pattern in badminton the following preventive matters are suggested: (a) changes in the badminton shoe, towards a higher heel, with shock absorption and a stiffer anatomically fitting heel counter; (b) adjustment of the friction between the individual shoe-soles and playing surfaces; and (c) specific badminton training including stretching and strengthening of the triceps surae and the muscles involved in the internal and external rotation of the shoulder and elbow during the badminton strokes.     

A comparison of heart rate responses in racquet games.

The present study investigated the heart rate response to playing tennis with special reference to the skill levels and ages of the participants. Data obtained in a similar manner during earlier studies of badminton and squash players were compared with that obtained during tennis. The number of rallies, mean rally time and actual playing time in 30 minutes of play was also compared for the different skill levels and sports. Results showed that playing tennis raised the players' heart rates to 68-70% of their predicted maximum heart rate (PMHR). Playing squash and badminton could raise heart rates to 80-85% of the players' PMHR which was significantly higher than the values obtained for tennis. The actual skill level of the participants within their chosen sport did not have a significant effect in predicting the physical demands of squash or tennis but was important in predicting the heart rate response of badminton players. The more skillful the badminton player the greater the cardiac response as a result of game play. Analysis of time spent in actual play revealed that tennis players were involved in play for only five of the thirty minutes of game play, compared to 15 and 10 min respectively for squash and badminton. Skill level within each sport was only a significant factor in predicting length of play for squash players in which the medium and highly skilled groups played significantly longer than those of a lower level of skill.     

Type of sport is related to injury profile: A study on cross country skiers,swimmers, long‐distance runners and soccer players. A retrospective 12‐month study

This 12‐month retrospective questionnaire compared the occurrence of sports injuries in 149 cross country skiers, 154 swimmers, 143 long‐distance runners and 128 soccer players aged 15–35 years. Soccer had significantly more injuries (5.1 injuries/1000 exposure hour) than other sports (2.1–2.8, P<0.001). More runners than soccer players reported overuse injuries (59% vs 42%, P=0.005), locating typically in the foot in runners, soccer players and skiers. Swimmers reported overuse injuries in the shoulder more commonly than skiers (40% vs 1%, P<0.001), who also intensively load shoulders. Acute injuries in skiers (80%) and in swimmers (58%), and overuse injuries in skiers (61%), occurred during exercise other than own event. In soccer and running the absence time from sport because of injuries was significantly longer than in skiing and swimming. No severe permanent disabilities occurred due to injury but seven women quit sports because of injury. In conclusion, type of loading is strictly associated with the anatomical location of an overuse injury as shown by the difference in shoulder injury incidence between swimmers and cross country skiers. In some sports, a significant proportion of acute injuries occur in other than the main event.     

A 1‐year prospective analysis of injuries in amateur and elite fistball

The purpose of this study was to examine the incidence and mechanisms of acute injuries in the sport of fistball. No scientific studies on injury characteristics have yet been conducted in this traditional sport game. The study was conducted prospectively over the course of 12 months. During a total of 40.308 h of sport‐specific exposure, 240 players reported 492 injuries, representing an overall injury rate of 12.2 injuries/1000 h of exposure. Most injuries were classified as bagatelle injuries (67.8%). The majority of the injuries were located in the knee (23.5%) followed by the elbow (11.9%) and the hip (11.5%). Ankle injuries resulted in the longest impairment from sports participation. The most common types of injury were abrasions (38.2%), contusions (21.1%), distortions (7.5%) and muscle strains (6.9%). Wrong or insufficient equipment (15.0%) was the most commonly mentioned causes of injury. The data indicate that the injury risk in fistball is rather high; however, the sport should not be considered a high‐risk sport because most of the injuries are slight and do not prevent the players from training or competition. Injury prevention strategies should include the development of fistball‐specific protective equipment with focus on the knee and elbow joint.     

Foot morphology and foot/ankle injury in indoor football

While the pronated foot is implicated as a risk factor for sports injury in some studies, others suggest that a supinated foot posture increases the risk of overuse lower limb injuries. Athletes in a given sports discipline may tend to have a similar foot morphology, which varies from that observed elsewhere. Further, the foot morphology that is beneficial for performance in a sport may be detrimental with regard to injury. Intra- and inter-rater reliability of the Foot Posture Index (FPI-6) as a measure of foot morphology was determined (ICC (2,1) 0.88 and 0.69 respectively). Thereafter, in a prospective cohort study using the FPI-6, 76 adolescent male indoor football (Futsal) players were measured and followed monthly over one competition season. Coach-rated ability and reports of any overuse injuries at the ankle and/or foot over this period were obtained. A significant negative linear relationship was found between the mean FPI-6 scores and coach-rated ability (p=0.008), with supinated and under-pronated postures related to higher ability level. Overall, 33% of injuries at the ankle and/or foot were classified as overuse. Foot Posture Index scores of less than 2, indicating the supinated and under-pronated feet, were found to be associated with a significant increase in the risk of overuse injury (p=0.008). The greater rigidity of these foot types may assist adolescent, male, indoor football players to perform at a higher level in their sport. Unfortunately, these players are also more likely to sustain ankle and/or foot overuse injuries.

Protective eyewear promotion: applying principles of behaviour change in the design of a squash injury prevention programme

Eye injuries in squash have the potential to be severe. Although these injuries can be prevented through the use of protective eyewear, few players wear such eyewear. The aim of this paper is to outline the behavioural principles guiding the design of a squash eyewear promotion initiative, the Protective Eyewear Promotion (PEP). Ecological principles of behaviour change were used to provide a comprehensive perspective on intrapersonal factors, policies and physical environmental influences of protective eyewear use. Results of baseline player surveys and venue manager interviews were used to provide relevant and specific intervention content. At baseline, protective eyewear was not found to be readily available, and players' behaviours, knowledge and attitudes did not favour its use. The main components of PEP involved informing and educating both players and squash venue operators of the risk of eye injury and of appropriate protective eyewear, as well as assisting with the availability of the eyewear and offering incentives for players to use it. A structural strength of PEP was the strong collaborative links with the researchers of different disciplines, the squash governing body, eyewear manufacturers, squash venue personnel, as well as players. Attempts were made within the project structure to make provision for the future dissemination and sustainability of more widespread eye injury prevention measures in the sport of squash.     

Injuries in team sport tournaments during the 2004 Olympic Games

BACKGROUND: Several authors have analyzed the incidence of injuries in a given sport, but only a few have examined the exposure-related incidence of injuries in different types of sports using the same methodology. PURPOSE: Analysis of the incidence, circumstances, and characteristics of injuries in different team sports during the 2004 Olympic Games. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: During the 2004 Olympic Games, injuries in 14 team sport tournaments (men's and women's soccer, men's and women's handball, men's and women's basketball, men's and women's field hockey, baseball, softball, men's and women's water polo, and men's and women's volleyball) were analyzed. After each match, the physician of the participating teams or the official medical representative of the sport completed a standardized injury report form. The mean response rate was 93%. RESULTS: A total of 377 injuries were reported from 456 matches, an incidence of 0.8 injuries per match (95% confidence interval, 0.75-0.91) or 54 injuries per 1000 player matches (95% confidence interval, 49-60). Half of all injuries affected the lower extremity; 24% involved the head or neck. The most prevalent diagnoses were head contusion and ankle sprain. On average, 78% of injuries were caused by contact with another player. However, a significantly higher percentage of noncontact (57%) versus contact injuries (37%) was expected to prevent the player from participating in his or her sport. Significantly more injuries in male players (46%) versus female players (35%) were expected to result in absence from match or training. The incidence, diagnosis, and causes of injuries differed substantially between the team sports. CONCLUSION: The risk of injury in different team sports can be compared using standardized methodology. Even if the incidence and characteristics of injuries are not identical in all sports, prevention of injury and promotion of fair play are relevant topics for almost all team sports.     

Injuries in Eleven Selected Sports

All the clubs for 10 sports in the four northern counties were surveyed for injuries for a whole playing season and a 50% sample of the badminton clubs were surveyed in the same way. After the two types of football, hockey comes third in the injury league with women getting injured mostly in the legs, but men in the upper part of the body. Protective padding for hockey players' legs is suggested. Finger injuries and occasional concussion are characteristics of cricket and sprains and strains of badminton. The severity rate in fencing was low with an occasional superficial cut. Cycling was safe, but when an accident did happen it usually produced multiple abrasions as can be readily understood by anyone who has fallen off a bicycle. Boxing and judo did not produce many injuries, but when they did, they were severe, and needed a relatively long time (on average 3 weeks) off sport. But, paradoxically the medical attention which they attracted was better than that attracted by the minor injuries of the other sports. Rowing and swimming were both very safe sports, notwithstanding the potentially hazardous nature of water. The injuries in sub-aquatic activities seemed to depend upon the club rather than upon the sport itself, which suggests that rather more careful supervision may sometimes be necessary.

The range of injury produced by sport is so wide—from a bruise to a brain injury—that it is difficult to avoid the conclusion that the hospital accident room is the right place to receive the injured player in the first instance. From here he can, if necessary, be routed to another department for more specialized treatment.

Introducing more first aid training into sport, at, perhaps, the level of club officials, players themselves, and in addition, regular supporters will be the most useful steps which can be taken in the management of sports injuries.

     

Hand injury patterns in softball players using a 16 inch ball

Softball is a popular recreational and competitive sport among both men and women. The injury rate in softball players is as high as that in baseball and basketball players. We conducted a retrospective analysis of 119 hand injuries in 108 patients treated at the University of Chicago hand clinic. All of the injuries were caused by the impact of a 16 inch circumference softball. Of the 119 injuries, 87 (73%) had bone involvement. Operative treatment was required in 26 (22%) injuries, 23 involving fractures and 3 involving soft tissue only. There was one (3.8%) operative complication. Of all injuries, 101 (86%) involved the finger joints, including 46 (39%) injuries to the distal interphalangeal (DIP) joint, 48 (40%) to the proximal interphalangeal (PIP) joint, and 7 (6%) to the metacarpophalangeal (MCP) joint. The most common DIP joint injury was a mallet injury. This fracture, the most common single type of injury in our series, accounted for 27% of all injuries. Of all mallet injuries, 86% were fractures. The most common PIP joint injury was a volar plate fracture, the second most common injury in our series. Variables such as the patient's sex, dominance or nondominance of hands, and early or late season play were not associated with a higher risk of injury. Certain parts of the hand, such as the more ulnar digits and the DIP and PIP joints, were at particularly high risk of injury.     

Epidemiology of musculoskeletal injury in the tennis player

Tennis is a popular sport with tens of millions of players participating worldwide. This popularity was one factor leading to the reappearance of tennis as a medal sport at the 1988 Summer Olympics in Seoul, South Korea. The volume of play, combined with the physical demands of the sports, can lead to injuries of the musculoskeletal system. Overall, injury incidence and prevalence in tennis has been reported in a number of investigations. The sport creates specific demands on the musculoskeletal system, with acute injuries, such as ankle sprains, being more frequent in the lower extremity while chronic overuse injuries, such as lateral epicondylitis, are more common in the upper extremity in the recreational player and shoulder pain more common in the high-level player. This review discusses the epidemiology of injuries frequently experienced in tennis players and examines some of these injuries' correlation with the development of osteoarthritis. In addition, player-specific factors, such as age, sex, volume of play, skill level, racquet properties and grip positions as well as the effect of playing surface on the incidence and prevalence of injury is reported. Finally, recommendations on standardisation of future epidemiological studies on tennis injuries are made in order to be able to more easily compare results of future investigations.     

Sex-related injury patterns among selected high school sports

This cohort observational study was undertaken to test the hypothesis that the incidence of injuries for girls participating in high school sports is greater than that for boys. From 1995 through 1997, players were included in our study if they were listed on the school's varsity team roster for boys' or girls' basketball, boys' or girls' soccer, boys' baseball, or girls' softball. Injuries and opportunities for injury were recorded daily. Certified athletic trainers reported injury and exposure data. Based on 39,032 player-seasons and 8988 reported injuries, the injury rates per 100 players for softball (16.7) and for girls' soccer (26.7) were higher than for baseball (13.2) and boys' soccer (23.4). The knee injury rates per 100 players for girls' basketball (4.5) and girls' soccer (5.2) were higher than for their male counterparts. Major injuries occurred more often in girls' basketball (12.4%) and soccer (12.1%) than in boys' basketball (9.9%) and soccer (10.4%). Baseball players (12.5%) had more major injuries than softball players (7.8%). There was a higher number of surgeries, particularly knee and anterior cruciate ligament surgeries, for female basketball and soccer players than for boys or girls in other sports.     

Personal risk factors associated with injury among female recreational ice hockey players.

INTRODUCTION: Women's ice hockey is a rapidly growing sport, however little is known about the injuries sustained by this group of athletes. PURPOSE: The objective of this research was to identify risk factors associated with injury among female recreational ice hockey players. METHODS: This prospective study followed players from two women's ice hockey leagues in Edmonton, Canada during the 1997-98 hockey season. The occurrence of injuries was monitored during the season through standardized telephone follow-up. Risk factors were determined using multiple logistic regression. RESULTS: The initial study sample consisted of 314 players, however as the season progressed 19 (6%) were lost to follow-up. The results of the study are based on 295 (94%) participants. A total of 125 injuries were reported; the injury rate was 7.5 injuries/1,000 player-exposures. Risk factors found to be significantly related to the occurrence of injury were: injury in the past year (OR= 1.57), more than 5 years of hockey experience (OR=1.49), and high exposure level (OR=1.41). CONCLUSION: This research is the first to quantify personal risk factors associated with injury among female recreational ice hockey players. A sports injury in the previous 12 months appears to be highly associated with injury and further research is required to more fully understand this relationship. The importance of controlling for level of exposure when investigating risk factors for sports injury was demonstrated.     

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.     

Coach and player attitudes to injury in youth sport

ObjectivesTo investigate coach and player attitudes to injury in New Zealand (NZ) secondary school sport.DesignCross-sectional surveySettingSecondary school sport.ParticipantsSecondary school coaches and players.Main outcome measuresResponses to a survey of injury attitudes. The survey was distributed in electronic and paper-based form to secondary school coaches and players across three sporting organisations. Coaches’ uptake of injury prevention training and whether they had first aid qualifications was also elicited.Results117 coaches and 226 players from netball, football and basketball participated. The majority of coaches surveyed (n = 82, 70%) reported having a coaching qualification and 72 (62%) had completed a sport related first aid/injury prevention programme. Overall, 196 players (87%) reported hiding an injury to continue playing, and 102 coaches (87%) and 205 players (91%) had witnessed injured players play on. Approximately 50% of players and coaches had seen players put under pressure to play when injured. A lack of knowledge, the desire to win, and not letting the team down were key reasons given for the behaviour reported.ConclusionsThe observed prevalence of players playing on when injured and associated attitudes to secondary school sport injuries demands further investigation.     

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.     

Impact of school sports injury

BACKGROUND: Most injuries in school occur during sport. OBJECTIVES: To explore the impact of sports injury in supervised school sport. METHOD: A prospective study of sports injury in children of secondary school age presenting to the accident and emergency department. Each patient was identified on registration, matched with medical records after discharge, and contacted later by telephone to complete a structured interview. Patients were only included if their injury was sustained during supervised school sport. RESULTS: During the study period, 194 patients aged 11-18 attended the accident and emergency department with an injury, 51% of which occurred during school sport. Injuries occurred most commonly in rugby (43%), followed by physical education and games together (17.5%). Most injuries were x rayed (72%). Just over 12% of pupils lost no time from sport, most (71%) were back to sport within three weeks, and 2.7% were injured for more than eight weeks. Almost a third of parents needed to take time off from work to deal with the injured child. CONCLUSION: School sports injuries are important. They account for just over half of all injuries in secondary school children. They cause significant disruption to school and sport and have important implications for the wider family.
