Definition of Neurosurgery:

The Board approved the following revised definition on Neurological Surgery, as submitted by the Joint Socio-Economic Committee at its December 1982 meeting:

Neurosurgery is the medical discipline that deals with the diagnosis, evaluation, and treatment of disorders of the central, peripheral, and autonomic nervous system, including their supporting structors, i.e., the spine and vascular supply, i.e., carotid and vertebral arteries; the evaluation and treatment of other pathological processes which modify nervous system function; the modification of the activity of the nervous system including the hypophysis and the management involved in the diagnosis, evaluation, treatment and rehabilitation of a patient utilizing all modalities in medicine.

The primary focus of my practice at this time is emphasis on the aggressive and comprehensive interdisciplinary team management of spine disorders. I emphasize a conservative approach that is a patient-centered partnership.
