Sports medicine requires multidisciplinary input and cooperation from many fields, including orthopaedics, emergency medicine, physiatry, and physical therapy. However, especially today, with the increased role of managed health care, it is the primary care physician, the pediatrician, the family practitioner, and the internists who care for patients who present with injuries caused by participation in sports. Sports Medicine: Principles of Primary Care has been written to provide a comprehensive guide for the primary care physician to the initial diagnosis and management of sports injuries. It provides precise guidelines on when to refer patients to specialists. Sports Medicine: Principles of Primary Care is organized to make all of the necessary information easily accessible through the use of treatment algorithms, boxed lists of differential diagnoses, and over 250 line drawings created specially for this work. It has a wealth of practical information. It covers problems with all of the body's systems, pre-participation evaluation, on-field emergencies, special problems to consider when treating female athletes, substance abuse, and how to care for the athlete who is physically disabled.
