Trends in neurosurgery. The 1989 AANS presidential address

This overview of neurosurgical practice examines patterns of case management, using several areas such as head injury, brain tumors, and the delivery of health care to illustrate the changes that have taken place over the past 40 years and the changes that might be expected in the next 40 years. The rapid pace of progress has indicated further exciting growth of this specialty into the 21st century; however, what remains constant is the dynamic character of the neurosurgeon. This view of the past and the possibilities for future innovation enables neurosurgeons of all generations to have a sense of pride in the achievements generated by their peers.
