Third-Year Medical Students
Welcome to Neurosurgery! Your week with us is an educational opportunity that is provided by only about 10 percent of medical schools in this country. We want you to experience the field of neurosurgery, expand your knowledge about the nervous system, and enjoy yourselves.
Those of you destined to become primary care providers will develop a basic knowledge of how neurosurgeons can help with some of medicine’s most common problems, such as back pain and stroke. Those who will eventually choose a medical or surgical subspecialty will learn how neurosurgeons collaborate with a variety of subspecialists to treat complex neurological disorders that demand intensive, multidisciplinary disease management. Those interested in Neurosurgery as a career will finally get to experience an immersive experience within their desired area of study.
During your Neurosurgery week, you will observe and/or assist in neurosurgical operations, participate in daily preceptor meetings, see outpatients in the Neurosurgery Clinic and/or attending offices, and attend Grand Rounds and other academic conferences. You have the option to take one night of call if you so desire. This is a Pass/Fail one-week rotation.
We sincerely hope that you find your experience on the Neurosurgery Service to be rewarding and informative!
