Hippocrates: a pioneer in the treatment of head injuries.

Hippocrates' treatise On Wounds in the Head represents an excellent source of information regarding the extent of experience with head injuries in classical antiquity. On the basis of clinical observation, the great physician gives an accurate description of the external appearance and consistency of the cranium. Fractures of the cranium are divided into six main categories, each of which is discussed separately, regarding its mechanism, clinical assessment, and treatment.
