Students following The Ohio State University’s College of Medicine rotations curriculum attend one month of rotations in Neurosurgery Service at University Hospital, Nationwide Children’s Hospital and Riverside Methodist Hospital.

You will round with the residents in the morning and take in-hospital calls every fourth night with the resident. If you have enough experience, during the fourth year you may act as a sub-intern. Neurosurgery residents teach you neurological examination, diagnosis and management of neurosurgical emergencies and the principles of head and spine injury management.

Along with faculty and residents, you are expected to attend weekly clinics and all conferences. Students are encouraged to attend surgery on the cases they work up, and once your faculty and resident decide you have enough experience, you will attend patients independently and present the patient to faculty. At the beginning of the rotation, you will be assigned a topic and must give a 15-minute presentation to the faculty and residents during the last week of the rotation.
