The National Institute of Arthritis and Musculoskeletal and Skin Diseases has a very helpful website on the topic of sports injuries. Every day, Florida children are injured as a result of sports related injuries. Some are just unfortunate occurrences. Many injuries, however, result from the failure to supervise children at practice or during free play. As parents, it is important to understand the nature and anatomy of the injury. The National Institute of Arthritis and Musculoskeletal and Skin Diseases Web Site is helpful in that it summarizes various injuries including injuries to the common areas such as the knee, ankle and shoulder.
