Sports Medicine involves not only traditional treatment; it is also a guide and reflection on the state of play according to sporting rules and breaches of them. Injuries that results from athletics predominantly involve the muscular and skeletal system. Sprains, strains, contusion of joints and muscle, and fractures and dislocations of bones and joints make up the bulk of these injuries. Head, face, neck injuries and internal injuries of thorax and abdomen statistically play a minor role, but they can be quite serious and even fatal. Abrasions and lacerations of the skin and bruises of the subcutaneous tissue are so common place that they represent red and then black and blue status badges of body contact. These injuries present no great difficulty in treatment unless they become infected.
