Epidemiology of women's gymnastics injuries.

Injury information from 98 participants in 2 years of interscholastic women's gymnastics competition in four Seattle area high schools was collected by certified athletic trainers. During the 2nd year of data collection, the study was expanded to include an additional 12-team high school league, 2 college teams, and 3 private clubs. A wide variety of injuries was observed, the total time loss injury rate was 39.8 injuries per 100 participant-seasons. Strains and sprains involving the back, particularly the lumbar region, appeared to occur more frequently than in most other interscholastic athletic activities. Ankle sprains were also common, and a relatively high frequency of thigh and leg strains and overuse problems of the leg were seen. This suggests that there may well be room for improvement in conditioning and other preventive programs in women's gymnastics.

Prophylactic knee bracing.

Six studies to determine the effectiveness of prophylactic knee braces in preventing medial collateral ligament (MCL) injury in football are compared. Criteria useful in evaluating studies are discussed, such as the probability of confounding factors, bias in selecting cases and controls, and variations in defining injury and exposure. Cost, as well as some ethical issues associated with mandated use are discussed. While four of these studies found a reduction in MCL injuries associated with using a brace, two of them reported increases. No consensus arises from these studies, conflicting results as well as methodological problems in some make it impossible to state with assurance the role of prophylactic knee bracing in football at this time.

Injuries in the 1987 national amateur volleyball tournament.

In a prospective study of injuries in the 1987 United States Volleyball Association's national tournament, we found 154 injuries in 1520 participants during 7812 hours of play. The injury rate in this study was 1.97/100 hours of play. Before the tournament, the participants' history was taken, and during the week of participation, records were kept of every player who presented with an injury. Players ranged in age from 17 to 60 and competed in five age/gender groups. Females had an injury rate of 2.3 and males had an injury rate of 1.7. The highest injury rate was seen in the men's open division, ages 17 to 35 (2.7), and the lowest rate was seen in the men's Golden Masters, ages 46 and up (1.5). Seventy-nine percent of the injuries occurred during the tournament and 21% were considered to be chronic injuries with an acute exacerbation. The upper extremities accounted for 20% of the injuries. The ankle (17.6%), low back (14.2%), and knee (11%) were the most common injury sites. Strains (36%) and sprains (28%) were the most frequent types of injury. Only eight (5.2%) injuries resulted in more than 5 days of time loss. Two of these injuries involved the knee and two others required surgery. It is likely that in studies relying upon retrospective methods, fewer of the less severe injuries are found, thereby leading to an overestimation of the percentages of knee and ankle injuries and the proportion of severe injuries. The clinician contemplating providing care for a high-level tournament should expect a preponderance of minor injuries occurring in a variety of anatomical locations.(ABSTRACT TRUNCATED AT 250 WORDS)

Injuries to pitchers in women's collegiate fast-pitch softball.

An injury survey of eight college softball teams ranked among the top 15 during the 1989 women's NCAA tournament championship by their athletic trainers found 26 injuries and complaints in 20 of 24 players. There were 15 grade I (nontime-loss) injuries, all musculotendinous except for a leg contusion and an ankle sprain. The 6 grade II injuries (altered play) were also musculotendinous except for 2 sprains to the hand and wrist. The 5 grade III (stopped play) injuries were somewhat more varied in type and resulted in an average of almost 7 weeks of time lost per injured player. Eighty-two percent of the time-loss injuries (grades II and III) involved the upper extremity. This survey suggests that there are likely to be a significant number of injuries involving loss of time from practice or games among elite women's fast-pitch softball pitchers.

Injuries in recreational adult fitness activities.

Volunteers (986) from fitness clubs and studios were recruited and followed for a 3-month period to document the injury consequences of adult recreational fitness participation. Participants were telephoned each week and their activities as well as any injuries that occurred were recorded. Of the 525 injuries and complaints reported during 60,629 hours of activity, 475 occurred as a result of sports participation for an overall rate of 7.83 per 1000 hours of participation. Seventy-six percent of these episodes caused the patient to alter or miss 1 or more activities, while 9.5% involved a physician visit. The rate for time-loss injuries was less than 2 per person per year (1.76 per 298 hours) or 5.92 per 1000 hours. Running had a higher risk of injury compared with most other individual sports. Cardiovascular fitness activities had low to medium rates, as did weight work; competitive sports were higher. For 6 of the most commonly injured areas, the reinjury rate was about twice that reported for those with no history of previous injury. The risks of injury from most recreational fitness activities were relatively modest, particularly if the activities were not competitive. Physicians might help patients reduce their risks of injury by encouraging suitable activities and by reducing the risks of reinjury by implementing appropriate rehabilitation programs.

Ballet injuries. An analysis of epidemiology and financial outcome.

The financial outcome and epidemiology of ballet dancers' injuries were studied by examining workers' compensation insurance records covering 3 seasons (3 years) of activity for a large professional ballet company. One hundred four dancers sustained 309 injuries that resulted in insurance payouts for medical costs of $398,396. The average cost per injury was $1289. Although only 4.2% of the injuries resulted in medical costs exceeding $5000, these represented 60.0% of the total medical costs. Nine injuries resulted in medical costs in excess of $10,000 each. Overall, there were 2.97 injuries per injured dancer. Twenty-four dancers (23.0% of the injured) sustained 5 or more injuries each and thus were responsible for 51.9% (161) of all injuries. The foot (74 injuries, 23.9%), lumbar spine (71, 23.0%), and ankle (41, 13.3%) were the most frequently injured anatomic regions. The experience of this ballet company is similar to that of a college athletic department or a professional sports team. All could employ similar strategies to reduce injuries and associated costs.
