Safety

Girls who play sports more than 8 hours per week are twice as likely as their less active peers to suffer a stress fracture, a new study finds. Most at risk were those engaged in three activities (running, basketball and cheerleading/gymnastics) which involve repeated jumping and landing which place particuarly high stress on bone, with the risk of injury increasing about 8 percent for each extra hour of activity over four per week.

Early recognition and treatment of common overuse injuries to growth plates is key to the safe return to play of young athletes says a new study.

Youth gymnasts are developing a wide variety of unusual arm, wrist and hand injuries from overuse, according to a study presented at the 2008 annual meeting of the Radiological Society of North America (RSNA).

Overuse injuries have become commonplace among young athletes in the last decade (although "Little League elbow" has been a problem for decades). They are not the kind suffered by children and adolescents engaging in free play or "pick up" games, but are clearly a product of the organized youth sports boom. The damage to hard and soft tissues resulting from undetected, unreported and often untreated overuse injuries can be permanent and lead to problems later in life, such as arthritis.
