The gender issue: epidemiology of ankle injuries in athletes who participate in basketball.

The increased participation of women in organized athletics has resulted in an interest in gender-related injury patterns. Previous reports have indicated an increased incidence in anterior cruciate knee injuries among female intercollegiate basketball players compared with their male counterparts. The current epidemiologic study prospectively evaluated the relative risk of ankle injuries in scholastic and collegiate basketball players during a 2-year period. Eleven thousand seven hundred eighty athletes participated in this study, 4940 females and 6840 males. There were 1052 ankle injuries. Overall, females had a 25% greater risk of sustaining a Grade I ankle sprain compared with their male counterparts. This increased risk was present in the interscholastic and intercollegiate players. There was no significant difference in the risk for Grades II and III ankle sprains, ankle fractures, or syndesmotic sprains. Male and female athletes doubled their risk for sustaining an ankle injury at the intercollegiate level compared with the interscholastic level.

Back pain in golf.

Although golfing is generally considered a begin activity, lower back pain is endemic among golfers. The golf swing subjects the lumbar spine to rapid, intense loads, more frequently in amateurs than in professionals. These loads predispose the golfing population to muscle strains, lumbar disc disease, spondylolysis, and facet joint arthropathy. It is imperative for all golfers to warm up properly, develop good swing mechanics, and participate in a lower back conditioning program off the golf course.

Rowing and sculling and the older athlete.

Rowing is a strenuous sport that has a significant injury rate among competitive participants. Consequently, older individuals who are anticipating beginning recreational rowing should start with a thorough physical examination by their physician. Because the back and knees are the most frequently injured areas, an orthopedic assessment of these regions is indicated in those individuals who have had previous patellofemoral or low back pain. All prospective rowers should begin with a general conditioning program that addresses lower extremity and abdominal strengthening, flexibility, and aerobic conditioning. A thorough understanding of the proper mechanics of rowing is essential to avoid potential injury. Rowing is a satisfying sport that offers excellent physical exercise and cardiovascular benefits. Older individuals should be encouraged to row, but also should be aware of the variety of injuries this sport may produce.

Myoelectric analysis of the paraspinal musculature in relation to automobile driving.

In this study, the myoelectric activity of 12 paraspinal muscles of ten men aged 18-24 was recorded to examine the effects of backrest inclination and lumbar support in relation to driving. In total, 24 test conditions were evaluated over a 3.5-hour period in a single day. These tests were then repeated, changing the sequence over the next 4 days. The results indicate a complex interaction between the thoracic and lumbar regions of the back with the lowest myoelectric activity position of 120 degrees backrest inclination, 5 cm of lumbar support, and 13.5-18.5 degrees of seat inclination. Electromyogramatic (EMG) evidence of fatigue was not identified over a 3.5-hour period. The generally low levels of EMG activity and, presumably, disc pressure present in any seating position suggest that the paraspinal muscle activity may not play the predominant role in disc herniation as it relates to automobile driving.

Impact loading of the lumbar spine during football blocking.

The purpose of our study was to determine the impact force to the lumbar spine when football players hit a blocking sled. We quantified the loads at the L4-5 motion segment throughout the blocking sequence. Five Division I-A college football linemen were subjects for our study. Kinematic data were obtained while the subjects hit a blocking sled instrumented with a force plate. Three plane forces were then calculated from these data. The average impact force measured at the blocking sled was 3013 +/- 598 N. The average peak compression force at the L4-5 motion segment was 8679 +/- 1965 N. The average peak anteroposterior shear force was 3304 +/- 1116 N, and the average peak lateral shear force was 1709 +/- 411 N. The magnitude of the loads on the L4-5 motion segment during football blocking exceed those determined during fatigue studies to cause pathologic changes in both the lumbar disk and the pars interarticularis. These data suggest that the mechanics of repetitive blocking may be responsible for the increased incidence of lumbar spine injury incurred by football linemen.
