Between 1980 and 1983, 21 young, high-performance gymnasts with stress changes related to the distal radial epiphysis, were treated and followed for a mean of 24 months (range, 6 to 42 months). Eleven of the gymnasts presented with roentgenographic changes of the distal radial epiphysis, and in these recovery took at least 3 months. This group was compared to a group of ten gymnasts who had similar symptoms but no roentgenographic changes, and who recovered within an average of 4 weeks. The roentgenographic changes, which are described in detail, are considered to represent stress changes, possibly stress fractures, of the distal radial epiphysis. No residual growth-related problems have been observed. Possible etiologic factors are discussed, and the literature as it pertains to stress-related adaptation and injury in the growing athlete is reviewed.

An epidemiologic investigation of injuries affecting young competitive female gymnasts.

A prospective study of injuries affecting 50 highly competitive young female gymnasts was conducted over a period of 1 year. Many of the findings of this investigation were consistent with previous studies and suggest particular injury trends in women's gymnastics. These results included injury location, injury severity, nature of onset, event, and activity at the time of injury. Some of the descriptive results, however, provided information that was heretofore unreported or inconsistent with previous investigations. These findings involved injury rate, reinjury rate, time loss, injury type, hours of practice, and incidence of physician-seen injuries. Some of these findings were disturbing and echo concerns registered in the professional literature. In particular, the reinjury rate is alarming and points to the need for complete rehabilitation before return to full participation. The results of the analytic component of the study alluded to the potential role of competitive level and maturation rate in the profile of the injury-prone gymnast. Specifically, rapid periods of growth and advanced levels of training and competition appeared to be related to injury proneness. Pursuant to the descriptive and analytic results of the investigation, recommendations for injury prevention and continued research are made.

Stress changes of the distal radial growth plate. A radiographic survey and review of the literature.

We conducted a radiographic survey to determine skeletal age and the nature and prevalence of stress-related changes affecting the distal radial growth plate in 60 young competitive gymnasts (39 females, 21 males). Comparison of results for chronological and skeletal age revealed a significant delay in maturation for girls (P less than 0.001). Radiographic evaluation revealed 5 gymnasts (4 girls and 1 boy) with stress-related changes of the left wrist, and four of these were considered to be minimal. These results, in conjunction with our previous findings and the review of related literature, reveal three important observations. First, the widening and irregularities of the distal radial physis that we described previously appear to be the first in a spectrum of abnormal changes secondary to overuse and probably represent a stress fracture of the distal radial growth plate. The radiographic changes associated with this injury are not the normal adaptive changes seen in young, competitive gymnasts. Secondly, more serious long-term abnormality may result even though the injury may initially resemble a Salter-Harris type I or II stress fracture. Long-term complications may include symmetrical or asymmetrical retardation or halted growth at the affected site, positive ulnar variance, and associated pathoanatomic sequelae. Thirdly, the incidence of distal radial growth plate stress injury remains unclear; we recommend a further, large-scale prospective epidemiologic study involving both male and female gymnasts. We urge that physicians and other health professionals associated with gymnastics clubs educate coaches about the possibility of significant injury to the distal radial physis, risk factors, and suggested preventive measures.
