RESUMEN
The Society of Neurological Surgeons (SNS), founded in 1920, is one of the oldest neurosurgical society in the world. The founding members were prominent surgeons that met with the idea of furthering the field of neurosurgery. Initial meetings were forums to observe and discuss new surgeries. During the first 6 meetings of the SNS, surgical cases from the areas of cranial trauma, epilepsy, spinal cord tumors, brain tumors, pituitary tumor, trigeminal neuralgia, and cerebellar tumors were discussed. Publications from the members during that time included articles on the use of intracranial hypertonic saline, trigeminal neuralgia, brachial plexus injuries, management of head injury, spinal cord tumors, cervical spine trauma, and intracranial hemorrhage in the newborn. The members also invited lecturers from other specialties, such as neurology, ophthalmology, radiology, and pathology, typifying the interdisciplinary nature of neurosurgical practice. The meetings served as a forum to build consensus on neurosurgical treatment methods. Cases that ultimately changed the practice of neurosurgery at that time will be profiled. The SNS began as a traveling club of neurosurgical leaders who learned from each other's clinical experience to mold this burgeoning new field. However, the members made an impact on how neurosurgery was practiced nationally.
