Seventy-five retired baseball players participated in a survey (37.8% response rate) in order to establish the long-term consequences of injuries sustained during their playing careers. Respondents had a mean age of 55.8 (+/-11.4) years with a mean age of 41.3 (+/-11.4) years at retirement from play. The mean overall rate of injury suffered per player/playing career was 5.6 (+/-7.1). 54.7% of respondents experienced a major injury (i.e. injury resulting in 5 or more consecutive weeks absence from training and play) with a mean major injury per player/playing career of 1.5 (+/-2.2). The rate for significant injuries (i.e. injury resulting in more than 1 week but less than 5 weeks absence from training and play) was 4.1 (+/-6.5) per player/playing career. Catchers had significantly less injuries than all other positions (p=0.027). 18.7% of all respondents reported suffering from arthritis, 24% from restricted joint mobility and 4% from chronically stiff fingers; all of these conditions were associated with their participation in baseball based on medical examination by their GP or medical specialist. 29.3% of respondents indicated that they had incurred additional medical costs and 12% reported significant loss of income associated with their injuries. Some injuries were severe enough that they resulted in extended stays in hospital producing costs carried by the health care system.

Inline skating belongs like ice hockey, rugby, and boxing to sporting activities with high-risk of suffering tooth accidents. Because of high velocity and loss of balance, especially on uneven ground, the injury potential in inline skating is higher. The objective of this work was to conduct a comparative study between Switzerland and Germany. The questions focussed on the frequency of tooth accidents, their prevention by mouthguard and the level of information about emergency measures after dental trauma and the resulting consequences for athletes. Using a standardized questionnaire totally 612 individuals, 324 men and 288 women, in two countries belonging to three different divisions (fun, fitness and speed) were surveyed. Fifty-six (9.2%) of these 612 interviewees have already experienced a tooth injury while inline skating. More than half of all interviewed players (68.3%) were aware of the possibility of replanting avulsed teeth. Only 32.4% were familiar with the tooth rescue kit. Just 65.4% knew mouthguard and only 1.9% of those athletes (n = 12) wore a mouthguard while inline skating. The results show that the area of inline skating requires more information about preventing dental trauma through sports associations and dentists.

The aim of this study was to investigate insurance records for a one-year period to determine the injury frequencies and costs associated with different age groups in netball. The insurance records for all netball claims made during 1999 in Victoria were obtained from the insurer and entered into a database. The overall injury rate was 9.49 injuries per 1000 players, with 829 claims for injuries filed with the insurance company. Of all injuries claimed for, 85.3% were to the lower limb, 8.7% to the upper limb, 3.1% to the spine/torso and 2.9% to the head and face. Lower limb injuries accounted for 85.4% of costs, upper limb injuries 10.7% and head/neck/torso injuries 3.9% of total injury costs. Knee injuries accounted for 56.9% of total costs, with ankle and calf/Achilles injuries costing 12.7 and 11.8% of total costs, respectively. Injury prevention strategies should therefore be directed to three main injuries taking into account costs and incidence. These injuries were: ankle sprains, knee ligament sprains and Achilles tendon strains. Specifically, the prevention program for Achilles injuries should be directed to the >25 years age groups.

Aims: The aim of this study was to examine the involvement of adventure tourism and adventure sports activity in injury claims made to the Accident Compensation Corporation (ACC)., Methods: Epidemiological analysis of ACC claims for the period, July 2004 to June 2005, where adventure activities were involved in the injury., Results: 18,697 adventure tourism and adventure sports injury claims were identified from the data, representing 28 activity sectors. Injuries were most common during the summer months, and were most frequently located in the major population centres. The majority of injuries were incurred by claimants in the 20-50 years age groups, although claimants over 50 years of age had highest claims costs. Males incurred 60% of all claims. Four activities (horse riding, mountain biking, tramping/hiking, and surfing) were responsible for approximately 60% of all adventure tourism and adventure sports-related injuries. Slips, trips, and falls were the most common injury initiating events, and injuries were most often to the back/spine, shoulder, and knee., Conclusions: These findings suggest the need to investigate whether regulatory intervention in the form of codes of practice for high injury count activities such as horse riding and mountain biking may be necessary. Health promotion messages and education programs should focus on these and other high-injury risk areas. Improved risk management practices are required for commercial adventure tourism and adventure sports operators in New Zealand if safety is to be improved across this sector.

Lateral ankle sprains account for 85% of all ankle sprains. This common injury is most frequently sustained during sporting activity. The ATFL is the weakest of the lateral ankle ligament complex, and is most frequently injured. Ankle sprains are often undertreated, resulting in chronic pain, muscular weakness, and instability. The consequence of this common injury for professional sports clubs is days lost in training and matches missed due to injury as well as the cost of rehabilitation. In the UK, an estimated 302,000 ankle sprains are seen each year in Accident and Emergency Departments.

Preventing sports injury has rarely been cited as an appropriate action to respond to the obesity epidemic, and in fact a recent letter has suggested that those playing sport are as responsible for their predicament as those who are obese. This opinion piece argues that it is time for better prevention and management of sports injury to be seen as part of the complex solution to preventing obesity, rather than being a self-inflicted problem that governments should continue to ignore.

Objectives: (1) To characterize the demographics and external causes of pediatric sports injury-related visits (SIRVs) to emergency departments (EDs). (2) To analyze the effect of race/ethnicity and insurance on SIRVs to EDs., Methods: A stratified random-sample cross-sectional survey of EDs in the National Hospital Ambulatory Medical Care Survey was conducted from 1997-2001; for patients younger than 19 years, we used all visits [n = 33,654; injury-related visits (IRVs) = 13,496, SIRVs = 2990]. We examined both the external cause codes and the actual verbatim text of all IRVs. National estimates of pediatric IRVs were obtained using the assigned patient visit weights in the National Hospital Ambulatory Medical Care Survey databases and SUDAAN 9.1 software (SAS Institute, Inc., Cary, NC)., Results: Sports injuries resulted in 2.5 million visits annually, or 23% of ED IRVs. Male sex, older age (6-18 years), and white race/ethnicity are associated with higher rates of SIRVs. Cycling, basketball, playground injuries, and football resulted in the largest numbers of ED SIRVs. Leading diagnoses for SIRVs included fractures and dislocations, sprains and strains, open wounds, and contusions. Hispanic race/ethnicity was associated with lower rates of SIRVs across all insurance types. After controlling for demographic factors and insurance, Hispanic children were less likely to have an SIRV than white children (odds ratio, 0.7; 95% confidence interval, 0.6-0.9)., Conclusions: Sports and recreation are the leading causes of pediatric ED IRVs. Hispanic children, regardless of insurance status, had lower rates of SIRVs than white children, which helps explain the lower rate of nonfatal IRVs to EDs among Hispanic youth.

Background: There has been a resurgence of skateboarding, rollerblading and BMX riding in recent years and in response dedicated skateparks have opened in many cities across the UK. It is acknowledged that these sports are associated with risk of injury and it is recommended that participants wear protective clothing., Objective: We aimed to determine if the opening of a skatepark near our hospital had any effect on the number of skatepark related injuries attending the emergency department and to describe the types of injuries sustained., Methods: All patients attending the emergency department with sports injuries were identified over 24 consecutive weeks. At the end of the 12th week a skatepark opened nearby. Data recorded prospectively included age and sex of subjects, the delay from injury to presenting to hospital, whether or not protective equipment was worn and if first aid was administered before attending hospital. The investigations performed in the emergency department, the diagnosis, treatment received and disposal from the hospital were also recorded., Results: After the skatepark opened there was a significant increase in the number of skatepark related attendances from 7 to 32. Protective clothing was only worn by 9 out of 39 of those with injuries. The commonest injuries were musculoskeletal and the limbs were injured more frequently than the head and trunk., Conclusion: We demonstrated a significant increase in the number of skatepark related injuries attending the emergency department following the opening of a nearby skatepark.

A comparison is made between abbreviated formal neuropsychologic testing programs and computerized neuropsychologic programs such as ImPACT, Headminders, CogSport, and others. Issues of time, cost, need for supervision, liability, and validation are discussed. Specific time and monetary costs per athlete are calculated for each program. The estimated cost is between $22 and $27 per athlete for abbreviated formal testing and between $669 and $677 per athlete for computerized testing. Because of the significant time and monetary costs of neuro-psychologic testing, its lack of validation in deter-mining recovery, limited validation and utility in diagnosing concussion, and its numerous logistic concerns, its widespread use is probably not justified until appropriate data are published and costs contained. Recommendations for alternative evaluation techniques are suggested.

Objectives: To evaluate the cost effectiveness of a proprioceptive balance board training programme for the prevention of ankle sprains in volleyball., Methods: A total of 116 volleyball teams participated in this study which was carried out during the 2001-2002 volleyball season. Teams were randomly allotted to an intervention group (66 teams, 628 players) or a control group (52 teams, 494 players). Intervention teams followed a prescribed balance board training programme as part of their warm up. Control teams followed their normal training routine. An ankle sprain was recorded if it occurred as a result of volleyball and caused the subject to stop volleyball activity. The injured player completed a cost diary for the duration of the ankle sprain. Analyses were performed according to the intention to treat principle. Mean direct, indirect, and total costs were calculated and were compared between the two groups., Results: The total costs per player (including the intervention material) were significantly higher in the intervention group (36.99 (93.87)) than in the control group (18.94 (147.09)). The cost of preventing one ankle sprain was approximately 444.03. Sensitivity analysis showed that a proprioceptive balance board training programme aimed only at players with previous ankle sprains could be cost effective over a longer period of time., Conclusions: Positive effects of the balance board programme could only be achieved at certain costs. However, if broadly implemented, costs associated with the balance board programme would probably be lower.

Unlabelled: The purpose of this study was first, to identify the health costs of knee surgery related to different sports (football, floor ball, European team handball and ice hockey) among players at competitive level in Stockholm 1997. Information was retrieved from three different databases, one containing information on all players in different sports, another one containing information on all surgery performed at S:t Gorans Hospital, Stockholm, and a third one containing information on all surgery performed in Stockholm. The National Registration Number (NRN) was used to identify the patients. The NRN is a unique personal identifier assigned to all Swedish residents, which allows linkage between different registers and databases. In Stockholm in 1997, 6781 surgical procedures related to the knee were performed at a cost of SEK (Swedish Crowns) 39,026,657. On players in all studied sports, 762 knee surgical procedures were performed on 657 patients in Stockholm at a cost of SEK 4,884,076. At S:t Gorans Hospital, 319 knee surgical procedures were performed on 288 patients, and 293 (92%) of these were directly related to sport participation. It was also found that only 74% of anterior cruciate ligament injuries that resulted in a surgical intervention were reported to the insurance company., Conclusion: The average cost for knee surgery in the studied sports was low. Knee surgery costs for European team handball players were the highest compared with other sports studied.

Injury claims from an insurance company specializing in soccer coverage were reviewed for a 5-year period. A total of 8215 injury claims (3340 females, 4875 males) were divided into three categories: (1) all injury, (2) knee injury, and (3) ACL injury. Knee injuries accounted for 22% of all injuries (30% female, 16% male). ACL injury claims represented 31% of total knee injury claims (37% female, 24% males). The youngest ACL injury was age 5. The ratio of knee injury/all injury increased with age. Compared with males, females demonstrated a higher ratio of knee injury/all injury and a higher ratio of ACL injury/all injury. This study demonstrates that ACL injury occurs in skeletally immature soccer players and that females appear to have an increased risk of ACL injury and knee injury compared with males, even in the skeletally immature. Future research related to ACL injury in females will need to consider skeletally immature patients.

Introduction: Injuries sustained by Australian Defence Force (ADF) personnel during non-combat military training and sports activity are associated with increasing costs due to work days lost, medical treatment, compensation, and early retirement. In 2001, the ADF commissioned a systematic review of the evidence-base for reducing injuries associated with physical activity, while at the same time improving physical activity participation rates to sustain a trained, fit and deployable workforce., Method: Literature from on-line library databases, relevant unclassified military reports, and material from previously published sport-specific injury countermeasure reviews were systematically and critically analysed to address the study aims., Results: Modification of intensity, frequency and duration of basic military training activities and improved equipment is likely to reduce injury occurrence. Sports injury countermeasures used for the civilian population have merit for the ADF physical activity program. Injury countermeasures should be designed to minimise any possible deterrent effect on the motivation to participate in regular physical activity. Increasing the participation of ADF personnel in physical activity in the presence of evidence-based injury prevention strategies has the potential to increase health, fitness and deployability with minimal impact on injury frequency., Conclusion: Recommendations arising from the review include injury intervention trials in basic military training and sports. These and other interventions should be supported by refinement to ADF injury surveillance systems. Research should focus on interventions with the greatest gain for fitness, deployability, and cost effectiveness.

Background: This study aims to estimate the burden and describe the profile of equestrian injuries in Greece, where horses, donkeys, and mules are still used in agriculture and where horse riding is a popular leisure activity., Methods: Prospectively collected information on 140,823 injuries reported in the national Emergency Department Injury Surveillance System was examined and 244 equestrian-related injuries that occurred during farming, equestrian sports, or horse racing were analyzed., Results: The estimated countrywide injury incidence for farming and equestrian sports combined was 21 per 100,000 person-years, but it was 160 times higher for horse-racing personnel. Men had higher rates of racing injuries and women had higher rates of equestrian sport injuries. Fractures accounted for 39.0% of injuries in horse racing and 30.5% in farming; head injuries accounted for approximately 50% of injuries among farmers. Farming injuries were more serious, with 25% requiring hospitalization. Analysis through the Barell matrix pointed to the role of spurs in the causation of ankle fractures and dislocations and the likely contribution of helmets in preventing traumatic brain injuries., Conclusion: Equestrian-related injuries are a serious but underappreciated health problem and merit targeted prevention efforts for each category affected.

Objective: To evaluate the influence of average family income in a geographic area on the effectiveness of helmet legislation on observed helmet use by children (5-14 years)., Methods: The study was conducted in East York, a health district of Metropolitan Toronto, in collaboration with the East York Health Unit. In 1996, the total population was 107 822, 11 340 of which were children 5 to 14 years. Census data were used to group the 21 census tracts in East York into 7 geographically distinct areas. The boundaries of these areas are natural barriers to travel, such as expressways, ravines, railway tracks, and hydroelectric power lines. The areas were also ranked according to average family income (based on Statistics Canada data). For analytical purposes, areas were defined as low-, mid-, and high-income areas. Census data profiles of the areas have been previously described. For each consecutive year from 1990 to 1997 inclusive, direct observations of children riding bicycles in East York during the months of April through October were made. In 1995, observations were completed before the introduction of the law on October 1, 1995. Only children who were between 5 and 14 years of age and riding a 2-wheeled bicycle were included in the study. In total, 111 sites across all 7 areas were selected for observation. Observational sites included school yards of all elementary and middle schools (kindergarten to grade 8) and all parks in East York. In addition, 5 major intersections and 5 residential streets from each area were randomly selected. Observers were trained and used a standardized data collection form. A pilot study showed that the data collected by observers were reliable and valid. Observers remained at each site for 1 hour and collected data on helmet use and sex. Ethical approval for the study was obtained from the Hospital for Sick Children Research Ethics Board, the East York Board of Education, and the Metropolitan Separate School Board. The proportion of children who were wearing a bicycle helmet was estimated by year (1990-1997, inclusive), sex (male, female), location (school, park, major intersection, residential street), and income area (low, mid, high). For estimating the effect of legislation on helmet use, data from the year immediately after legislation (1996) were compared with data from the year preceding legislation (1995). The relative risk (RR) of helmet use (after vs before legislation) was calculated along with a 95% confidence interval (CI). Logistic regression analysis was used to adjust for potential confounding variables (sex and location)., Results: During the 8-year study period, 9768 observations were made (range: 914-1879 observations per year). The proportion of child cyclists who wore a bicycle helmet increased steadily during the first 4 years of the study period, from 4% in 1990 (34 of 914), to 16% in 1991 (303 of 1879), to 25% in 1992 (383 of 1563), and to 45% in 1993 (438 of 984). During 1994 (460 of 1083) and 1995 (568 of 1227), helmet use remained relatively stable at approximately 44%. Helmet use rose markedly in 1996 (the first year after helmet legislation was introduced) to 68% (818 of 1202) and remained stable at 66% (609 of 916) in 1997. Throughout the study period, girls were consistently more likely to wear helmets than were boys. In total, 47% (1420 of 3047) of girls wore helmets, compared with 33% (2193 of 6721) of boys (RR: 1.43; 95% CI: 1.36-1.50). In addition, children who were riding to school were more likely to use helmets, compared with children who were riding on residential streets, major intersections, and parks. Overall, 48% (1497 of 3129) of children who were riding to school wore bicycle helmets, compared with 32% (2116 of 6639) of children who were riding at other locations (RR: 1.50; 95% CI: 1.43-1.58). Children in the high-income areas were consistently more likely to wear helmets, compared with children in the mid- and low-income areas. Helmet legislation was associated with a significant increase in helmet use by children in East York. In 1995, 46% (ast York. In 1995, 46% (568 of 1227) of children wore bicycle helmets, compared with 68% (818 of 1202) of children in 1996 (RR: 1.47; 95% CI: 1.37-1.58). The effect of legislation, however, varied by income area. In low-income areas, helmet use increased by 28% after legislation, from 33% (213 of 646) in 1995 to 61% (442 of 721) in 1996 (RR: 1.86; 95% CI: 1.64-2.11). In mid-income areas, helmet use increased by 29% after legislation, from 50% (150 of 300) in 1995 to 79% (185 of 234) in 1996 (RR: 1.58; 95% CI: 1.39-1.80). In high-income areas, helmet use increased by only 4%, from 73% (205 of 281) in 1995 to 77% (191 of 247) in 1996 (RR: 1.06; 95% CI: 0.96-1.17). This finding of a significant increase in helmet use after legislation in low- and mid-income areas but not in high-income areas remained even after logistic regression analysis adjusted for sex and location., Conclusions: This study showed that bicycle helmet use by children increased significantly after helmet legislation. In this urban area with socioeconomic diversity and in the context of prelegislation promotion and educational activities, the legislative effect was most powerful among children who resided in low-income areas.

Hurling is a contact sport, associated with significant morbidity. We have identified specific hand injuries sustained by participants and quantified the functional and financial implications of these injuries. Over a 3-month period, all hand injuries seen in the fracture clinic of our regional trauma unit were studied prospectively. Of the 123 consecutive injuries, 41 (33%) were sustained during hurling matches. Metacarpal (47%) and proximal phalangeal (37%) fractures were the most frequent. Eight hurlers (20%) required surgical intervention. Only four (10%) of the injured players were wearing hand protection. The mean cost of injury to the player was pound 615. We suggest the introduction of the mandatory use of hand protection for hurling.

In this article, we review the available data on sporting injuries to the head and neck and discuss sport-specific injury risk and prevention strategies, as well as the costs of head and neck injuries.

Forty million individuals participate in organized softball leagues each year in the United States. Eighteen million additional student athletes and young adults also participate in organized baseball league play. In addition to being two of the most popular team sports in the United States, they also are responsible for a significant percentage of sports-related injuries that are sustained in the United States. Fortunately, numerous interventions independently have been shown to be effective at reducing the injury scenario, which has grown to be of epidemic proportion. Interventions such as break-away bases, batting helmets, face shields on helmets, lighter mass baseballs, and teaching and reiteration of the fundamentals of softball and baseball all have been effective in preventing millions of injuries and billions of dollars in healthcare costs each year in the United States.

This paper seeks to determine the cost to the NHS associated with treating parachute-related injuries. More specifically, it compares the training received by civilians to that received by military personnel together with the types of parachutes used or the type of jump. It also reviews the information given to civilian jumpers prior to their first jump. Fifty-three jumpers suffered injuries in the period under review. Of these, 32 cases with 41 injuries were transferred to Accident and Emergency Department for treatment. Injuries involved most of the musculoskeletal system. Twenty-six (n=32) patients were admitted for treatment, with an average length of hospital stay of 6.8 days. Post-discharge, the length of time lost from work was 42.8 days. The cost to the NHS was calculated at pound 4026.50 per patient treated. This did not include time lost from work, subsequent follow up or any other secondary procedures. Civilian parachute jumpers were trained for 6.5h compared to 31.5h for military personnel. Twenty-seven patients used rectangular rather than circular parachutes. Thirty of the 41 injuries occurred during static line jumps, with 7 occurring during tandem jumps and only 5 during free-fall jumps. Twenty-three of the 32 jumpers sustained the injury during their first jump. First-time civilian jumpers were given a minimum of information regarding risks and injuries prior to their jump and were inadequately insured against potential injuries. The cost of caring for these patients is substantial when compared to the money that is raised for charity during some of the jumps. Private insurance, with the NHS legally able to claim expenses would help to offset these medical costs. It is also possible that by increasing civilian training, there may be a reduction in the number of injuries sustained by first-time civilian jumpers from 1.1 to 1.2% (11% in charity jumps) to the military figures of 0.22-0.89%.

Background: Orthopaedic practice expenses are the costs associated with providing treatment that are incurred by a physician's practice. Certain payer types are thought to increase orthopaedic practice expenses by increasing paperwork and other administrative activities. Our study investigated the hypothesis that orthopaedic practice expenses would vary significantly by payer type., Methods: With use of the method of activity-based costing, data on the orthopaedic practice expenses for 518 consecutive patients (286 men and 232 women) who had a sports-related knee condition were collected. For each patient enrolled in the study, all employees recorded the actual amount of time that they spent on each of seventeen specific activities previously shown to be associated with orthopaedic practice. The seventeen activities were categorized as either a value-added activity, which adds value to the services provided to the patient, or a nonvalue-added activity, which does not add value. The total orthopaedic practice expense was the sum of the value-added and nonvalue-added activity expenses. To capture all practice expenses associated with a particular episode of care, data collection continued until the patient was discharged and the financial account had been settled. We evaluated the differences in orthopaedic practice expenses among six payer types: self-pay, indemnity plan, Medicare, health maintenance organization/point-of-service plan (HMO/POS), preferred provider organization (PPO), and Workers' Compensation., Results: The differences among payer types with respect to orthopaedic practice expenses were significant (p = 0.0000000004). The total orthopaedic practice expense per episode of care was $123 for self-pay, $195 for an indemnity plan, $148 for Medicare, $178 for PPO, $208 for HMO/POS, and $299 for Workers' Compensation. These differences among payer types persisted even after accounting for patient age, gender, treatment type (nonoperative versus operative), and number of office visits. Nonvalue-added activity expenses differed to a greater degree among the payer types than did value-added activity expenses., Conclusions: The payer type was found to be an important factor affecting orthopaedic practice expenses, particularly with respect to nonvalue-added activity expenses.

Sports injuries result in substantial costs to the Australian community and also act as a barrier to increased participation in physical activity. However, the Australian healthcare system has no coordinated approach for monitoring or preventing sports injuries. This is in contrast to New Zealand, which has a specific body responsible for managing sports injuries, in a similar way to work injuries and traffic accidents.

Acute injuries in the Swedish Police Force from on-duty fitness training were selected retrospectively from the Information System of Occupational Injuries (ISA) at the National Board of Occupational Safety and Health and, if having caused a sick-leave exceeding 2 weeks, to the Labour Market Insurance (AMF Insurance). The latter included injuries from 1995 only. During the seven-year period 1992 to 1998, 920 injuries (80 % in males) from fitness training involving police officers were reported to the ISA-register. The total incidence was 1.6 for policemen per 10 000 hours of exposure and 2.2 for policewomen, which is 1.4 times higher than in men. Around 50 % of the injuries occurred in team and contact sports, with a slightly higher percentage for males, 54 % versus 49 % in females. The percentage of injuries from self-defense training was twice as high as in women than in men, 29 % versus 15 %. In 1995, 42 of the 72 injuries in males and 6 of the 21 injuries in females caused more than 14 days of sick-leave and were announced to the Occupational No Fault Liability Insurance. The major part, 32 of 48 injuries, came from team or contact sports (mainly floorball and soccer). Six policemen incurred injuries that were classified with a degree of disability ranging from 2 to 5 %. The total cost for medical treatment and production loss for the 48 injuries was Euro 248 448 and 99 336, respectively. Team and contact sports accounted for 89 % of the costs and 77 % of the production loss through sick-leave.

More than 40 million individuals participate in organized baseball and softball leagues in the United States every year. Unfortunately, it has also been estimated by the Consumer Product Safety Commission that softball and baseball are the two main sports leading to emergency-room visits in the United States. A previous field study has determined that the utilization of breakaway bases has the potential of preventing 96% of sliding injuries, thereby preventing 1.7 million injuries a year in the United States with a savings of $2 billion a year in health care costs. It is the purpose of this study to analyze and compare the potential attenuating capabilities of various types of bases. We found the force at the ankle upon impact when compared to the standard base revealed all breakaway bases reduced the force of impact to a statistically significant level. The force at the foot upon impact when compared to the standard base revealed all breakaway bases reduced the force at variable levels, with the Rogers bases having the only statistically significant reduction. However, the force delivered to the tibia/fibula was increased with the Stay Down and Mag-Net large bases as compared to the standard stationary base. The moments of inversion/eversion and dorsiflexion/plantar flexion upon impact, when compared to the standard base, revealed all safety bases were reduced to a statistically significant level. We conclude breakaway bases reduce the force of impact and moments to a statistically significant level and confirm previous field studies. Though there is a difference among the breakaway bases themselves, they should be used on all fields.

Two hundred and ninety-five licensed floorball players from Finnish premier to fifth division were observed prospectively for one season to study the incidence, nature, causes and severity of floorball injuries. During the study period, 100 out of the 295 (34 %) players sustained 120 injuries. Thirty-seven percent (73/199) of the male players and 28 % (27/96) of the females suffered from an injury. The injury rate was 1.0 per 1000 practice hours for both sexes. The injury rates per 1000 game hours were 23.7 for men and 15.9 for women. One hundred injuries (83 %) were acute and the remaining 20 (17 %) were overuse injuries. Sprain was the most common type of injury in men while overuse injuries were the most frequent injury type in women. The lower extremity was involved in 62 %, spine or trunk in 19 % and upper extremity in 10 % of the injuries. The most commonly injured sites were the knee and ankle (22 % and 20 % of all injuries), followed by head and neck (8 %). In both sexes the majority of injuries were minor, level II, injuries. Ten of the knee injuries (38 %) were serious, level IV injuries, of which seven were ACL ruptures. In conclusion, the individual risk of injury in floorball is relatively low in game practice while rather high during the game itself. Before initiation of clinical trials on prevention of floorball injuries, an exact knowledge of the risk factors and mechanisms of floorball injuries are needed.

The aim of this study was to determine the severity and cost of injuries in amateur rugby league. Seventy-two amateur rugby league players aged 28 +/- 6 years (mean +/- s) were surveyed at the end of a competitive season. An injury was defined as any pain, disability or injury that occurred as a result of a competition game which caused the player to miss subsequent games. Injuries were classified as minor (one game missed), moderate (two to four games missed) and major (five or more games missed). Of the 72 questionnaires distributed, 34 (47.2%) were returned. Twenty respondents (58.8%) sustained an injury that resulted in one or more missed games. Eight injured players (40.0%) missed five or more training sessions, six of whom (30%) missed five or more games as a result of the injury. The median time lost from employment or study for all injured players was 2 days per playing injury. The respective median direct (e.g. medical expenses) and indirect (e.g. wages lost) costs associated with the injury were 28.29 pounds and 77.04 pound per playing injury. A considerable proportion of injuries sustained in the present sample of amateur rugby league players were major, resulting in a loss of training, playing and employment or study time, and these injuries were associated with significant direct and indirect economic costs. Further studies, using a larger sample, would complement the present findings in establishing the severity and cost of amateur rugby league injuries. These results suggest that prevention strategies are required to reduce the severity and cost of amateur rugby league injuries.

Defining high-quality care and cost-effectiveness is not an easy task. In this article, the authors describe several strategies that have practical applicability for the clinician treating patients with sports-related injuries. Integration of some of these strategies may allow the more quality-based, cost-efficient use of available resources in sports rehabilitation.

Knee injuries are common and account in various sports for 15-50% of all sports injuries. The cost of knee injuries is therefore a large part of the cost for medical care of sports injuries. Furthermore, the risk of acquiring a knee injury during sports is considered higher for females than for males. The nationwide organization "Youth and Sports" represents the major source of organized sports and recreation for Swiss youth and engages annually around 370000 participants in the age group of 14 to 20 years. The purpose of this study was to combine data on knee injuries from two sources, the first being data on the exposure to risk found in the activity registration in "Youth and Sports" and the second injuries with their associated costs resulting from the activities and filed at the Swiss Military Insurance. This allowed calculation of knee injury incidences, to compare risks between males and females and to estimate the costs of medical treatment. The study comprises 3864 knee injuries from 12 sports during 7 years. Females were significantly more at risk in six sports: alpinism, downhill skiing, gymnastics, volleyball, basketball and team handball. The incidences of knee injuries and of cruciate ligament injuries in particular, together with the costs per hour of participation, all displayed the same sports as the top five for both females and males: ice hockey, team handball, soccer, downhill skiing and basketball. Female alpinism and gymnastics had also high rankings. Knee injuries comprised 10% of all injuries in males and 13% in females, but their proportional contribution to the costs per hour of participation was 27% and 33%, respectively. From this study it can be concluded that females were significantly more at risk for knee injuries than males in six sports and that knee injuries accounted for a high proportion of the costs of medical treatment.

Mild head injury is a frequent occurrence in a multitude of athletic endeavors across all levels of play. Clinicians should carefully consider all interventions at their disposal to reduce the prevalence and severity of injury to protect those involved. The exploration and evaluation of using properly fitted mouthguards to provide effective, albeit limited, defense against brain injury merits attention. The minimal costs of such an intervention when properly applied would no doubt reap numerous benefits in terms of reducing the medical, financial, cognitive, psychological, and social consequences of mild head injury. The cosmetic salvation would be no small side effect to efficacious, properly fitted mouthguard use.

Background and Aims: The incidence of achilles tendon (AT) ruptures is increasing. The aim of the present study was to evaluate annual incidence, aetiology, operative complications and direct hospital costs of AT ruptures., Material and Methods: A retrospective study of 93 consecutive patients operated on for AT rupture from January 1986 to December 1996 at Kuusankoski District Hospital (area with 92,500 inhabitants) was performed. During the observation period no patient with an AT rupture was treated conservatively., Results: 95 AT ruptures were treated including one rerupture (1%) and one patient with two ruptures. There were 7 (7%) patients with an open AT rupture. The total annual incidence in the hospital area was 8.6 (+/- 4.3) and for closed AT ruptures 8.0 (+/- 3.8). The total incidence was 9.3 (+/- 4.6)/10(5) and for closed AT ruptures 8.6 (+/- 4.1)/10(5) inhabitants per year. Most of the injuries were sport related, the most frequent sport being volleyball. Patients operated for closed AT rupture had major surgical complications in 4.5% of the cases and the total complication rate was 11%. The average direct hospital costs per patient was USD 1375., Conclusions: The incidence of AT ruptures is increasing in South-East Finland. The rate of major surgical complication was low (4.5%) and comparable with earlier studies.

The popularity of personal watercraft is steadily increasing, as are injuries related to their use. Many of these injuries are not reported to law enforcement agencies, and available personal watercraft injury statistics are suspected to be inaccurate. All personal watercraft-related injuries treated within a four-hospital system (including the regional Level I trauma center) between January 1993 and December 1997 were retrospectively identified. Patient demographics, accident mechanism, injuries sustained, tourist status, outcome, and economic data were collected and compared with available government statistics for the same time period. Sixty-eight consecutive patients injured during personal watercraft use were identified. Of these, 78 per cent were treated and released, whereas 22 per cent required inpatient management. Fractures and soft tissue injuries were the most common injuries sustained. Ninety-seven per cent of patients were discharged home. There was one fatality. Comparison with state and federal statistics identified that personal watercraft injuries are significantly underreported and have an estimated yearly economic impact of more than $235 million. Personal watercraft injuries represent an increasing source of watersport-related trauma. Government statistics on personal watercraft injuries do not accurately reflect the true incidence and economic impact of such trauma. Mandatory educational programs and increased legislation to improve personal watercraft safety should be promoted.

Objectives: To determine whether integrating primary care sports medicine into academic emergency medicine (EM) can enhance both revenue and the academic program., Methods: A retrospective descriptive review of all patients seen in a primary care sports medicine practice at a university hospital sports medicine clinic was done over a 24-month period. All patients seen initially in the ED for a sports injury either by the author or by another EM faculty member with follow-up by the author in the sports medicine clinic were included in the study group. The study group was analyzed for diagnoses, payor mix, and revenue generated by the ED follow-up sports medicine clinic visits., Results: There were 199 patients who met the inclusion criteria. This resulted in 483 ED follow-up sports medicine clinic visits. The author practiced 13 hours/week in the ED and 16 hours/week in the primary care sports medicine practice, which resulted in 1,536 sports medicine clinic hours. The study group accounted for 20% of the total patient volume in the author's primary care sports medicine practice. There were 111 lower-extremity injuries (knee 52%, foot/ankle 40%, hip/pelvis 8%), 81 upper-extremity injuries (hand/wrist 48%, shoulder 43%, elbow 9%), and seven spine injuries. Payor mix was 47% traditional indemnity, 45% HMO, 4% self-pay, and 4% Medicare/Medicaid. Total charges for the ED follow-up sports medicine clinic visits were $44,767 ($92.68/visit) and net receipts were $30,276 ($62.68/visit). This represented 20% of the total charges and 16% of the net receipts in the author's sports medicine practice during this period. Revenue generated by the ED follow-up sports medicine clinic visits could have supported 12% of the equivalent cost of the base pay for a full-time EM faculty position., Conclusion: The integration of primary care sports medicine into an academic EM faculty practice can enhance revenue through the establishment of an ED follow-up sports medicine clinic while also providing an opportunity to expand resident learning experiences.

Background: Recent reports note a dramatic increase in the number of pediatric trampoline injuries (PTI) during the past several years. In 1996, the US Consumer Product Safety Commission estimates that 83 000 patients received treatment for trampoline injuries in US hospital emergency departments (EDs), and that approximately 75% of these patients were <15 years of age. We sought to review our experience with PTI since our previous report (Pediatrics 1992;89:849), and to determine if the American Academy of Pediatrics' current (Pediatrics 1981;67:438) safety recommendations are adequate., Methods: Retrospective medical record review of all PTI patients presenting to the pediatric ED from November 1990 through November 1997., Results: A total of 727 PTI patients were included; medical records were unavailable for 3 patients. The annual number of PTI nearly tripled during the study period, from 51 in 1991 to a peak of 148 in 1996. PTI patients were 53% female, with a median age of 7 years; 37% were <6 years of age. Privately owned trampolines accounted for 99% of PTI. Most injuries (66%) occurred on the trampoline, 28% resulted from falls off, and 4% from imaginative mechanisms. One hundred eleven patients (15%) suffered severe injury (1990 Abbreviated Injury Scale value >/=3), usually of an extremity (89 out of 111). Fractures occurred in 324 patients (45%). Spinal injuries were common (12%), including 7 patients with cervical or thoracic fractures, and 1 with C7 paraplegia. Fractures were more frequently associated with falls off the trampoline, whereas spinal injuries more frequently occurred on the trampoline. Eighty patients (11%) required prehospital medical transport to our ED, 584 (80%) had ED radiographs, and 382 (53%) required pediatric surgical subspecialty involvement. Seventeen percent of PTI patients (125 out of 727) were admitted to the hospital, including 9 to the pediatric intensive care unit; 99 (14%) required one or more operations. Mean hospital stay was 2 days (range, 1-63 days); 24 stays (19%) were for >/=3 days. We estimate that the hospital charges for the acute medical care of PTI study patients at our institution totaled approximately $700 000., Conclusions: PTI are dramatically increasing in number, and result in considerable childhood morbidity. Most PTI occur on privately owned trampolines. Few, if any, safety recommendations for the trampoline are followed. We support recommendations for a ban on the recreational, school, and competitive pediatric use of trampolines.

Competitive swimming is commonly thought to be an injury-free sport. Traumatic and overuse injuries do occur, especially if one includes accidents occurring to both athletes and spectators, and accidents resulting from some of the newer diving and starting techniques. United States Swimming, Incorporated, the national governing body for competitive swimming, and provider of insurance coverage for most of the swimming clubs in the United States, keeps track of reported injuries to club members, and requires specific safety accreditation for member coaches. These data provide an informative view on injuries to competitive swimmers.

Over a period of one year, all accidents associated with in-line skating (ILS) were surveyed. Sport-specific data was recorded with a standardized questionnaire. The study comprised 66 patients with 75 injuries (48 upper limb, 16 skull, eight lower limb, three trunk). We were looking after 42 male and 24 female patients with an average age of 20 years (5-53 years). Twenty-seven patients (40%) had to be treated as inpatients. Overall, the most frequent injury (one third of all injuries) was forearm fracture close to the wrist (21 radius fractures, four radioulnar fractures). It had to be reset in 20 cases. Additional internal fixation was required in 10 cases (Kirschner wire osteosynthesis, intramedullary nailing or plate osteosynthesis). Only five patients could be treated with plaster cast fixation alone. Most patients with injuries in the vicinity of the wrist were not wearing a wrist protector at the time of the accident. The most frequent reasons given for not wearing protectors was forgetfulness or the high price of protectors. However, there were also two distal radius fractures and a disc injury in the wrist in patients who had been wearing wrist protectors. In most cases, ILS accidents lead to appreciable damage requiring a healing period of several weeks to months (average period of loss of work 41 days). The bfu (advisory center for accident prevention) reckons with 60,000 ILS cases annually in Switzerland. These injuries are thus of great socioeconomic importance. In the future, better risk behavior must be achieved by informing the population (wearing protectors, especially for the wrist and head, attendance of training courses).

A 3-year chart survey and questionnaire was conducted of equestrian-injured patients at a regional trauma center to determine patterns and consequences of injury and rate of recidivism. Ninety-two patients (95 encounters) were treated; most were young (mean age, 27 +/- 11 years) women (84%) riders sustaining falls (80%). Most injuries were orthopedic (47%); 19 per cent of patients required hospital admission. There was one death. Helmet use was documented in only 34 per cent. Eighty-one per cent of patients responded to a follow-up telephone survey; 36 per cent recounted additional accidents (mean, 1.4 +/- 0.5). Mean time lost from work was 3 weeks, with 19 per cent reporting chronic disability. Mean annual hospital charges for the cohort were $88,925.00. Recidivism is common in equestrian trauma. Hospital charges are significant. Lost time from work is considerable, with one in five patients reporting long-term disability. Given the cost and disability incurred with equestrian trauma, efforts at injury prevention appear warranted.

A cross-sectional multicenter study was conducted to estimate the direct costs for each cause of spinal cord injury in the United States. Random samples of 227 new injuries and 508 persons 2-16 years postinjury were selected. Prospective data were collected during one year on all charges for emergency medical services, hospitalizations, attendant care, equipment, supplies, medications, environmental modifications, physician and outpatient services, nursing homes, household assistance, vocational rehabilitation, and miscellaneous items. In 1995 dollars, first year charges averaged $233,947 for vehicle crashes, $217,868 for violence, $295,643 for sports, $185,019 for falls and $208,762 for other causes. Recurring annual charges for each cause averaged $33,439, $17,275, $27,488, $26,238 and $23,510, respectively. Using average age at time of injury for each cause, a 2% real discount rate, and the most recent survival data from the National Spinal Cord Injury Statistical Center, average lifetime charges for each cause were $969,659, $613,345, $950,973, $630,453 and $673,749, respectively. Given an estimated 10,000 new cases of spinal cord injury occurring each year of which 35.9% are caused by vehicle crashes, 29.5% are caused by violence, 20.3% are caused by falls, 7.3% are caused by sports, and 7% result from other causes, annual aggregate direct costs of traumatic spinal cord injury in the United States are $3.48 billion for vehicle crashes, $1.81 billion for violence, $1.28 billion for falls, $694 million for sports and $472 million for other causes. Total direct costs for all causes of SCI in the United States are $7.736 billion.
