This book is a comprehensive reference guide for team physicians to manage common or rare clinical issues that may occur on the sidelines and field of play in recreational, professional or elite sports. Musculoskeletal injuries and health-related clinical issues that may occur on the field of play can directly impact the ability of athletes to safely participate in sport. Indeed, the ability to urgently respond to the myriad of health-related issues is critical during both sideline and event coverage. The variety of challenges may be more prevalent according to the type of sport, the athletes' physical condition, the field of play, the level of competition, as well as the environmental conditions. Initial assessment, proper investigation of athletes' clinical complaints and findings, followed by a well-practiced intervention protocol play an essential role in optimizing the outcome of each case. Written by an international team of experts, and published in partnership with ISAKOS, this book is an excellent source of knowledge for sports physicians, orthopedists and physiotherapists alike.
