Even today, doctors still use the treatments and methods developed by the ancient Greeks over two thousand years ago. The most important treatments used today would be those in the field of traumatology, a branch of surgery that deals with serious injuries caused by accidents or violence. Hippocrates, the founder of this field, began the development of this medical branch when he decided to document his medical methods and discoveries in “about 60 “Hippocratic” treatises” (Pikoulis 426). These treatises, known today as the Hippocratic corpus, are documents containing various detailed information about the human body and various ways developed to treat injuries encountered by classical era physicians. Within the Hippocratic Corpus the most studied was On Head Wounds which was the first document linking "dizziness and loss of consciousness to brain damage...[and] injuries to the left temple region cause spasms on the right side of the body and vice vice versa” (Pikoulis 426). This section has had great importance for moderns, because injuries to the head, and especially to the brain, are almost impossible to detect and most lethal injuries go untreated. Even someone who has received that who thinks it was a light blow to the head, may die hours later from an invisible intracranial attack.
