Philip R. Weinstein MD


Professor of Neurological Surgery

Dr. Weinstein specializes in the treatment of adult disc disease, adult spinal deformities and spondylolisthesis, spinal stenosis, complex spinal instrumentation, degenerative neurospinal disorders, spinal axis tumors, spinal cord vascular malformations, and spinal trauma or instability. 

Dr. Weinstein's research has chiefly concerned repair and regeneration after spinal cord injury, the cerebrovascular, cardiovascular, and metabolic aspects of cerebral ischemia, and mechanisms of brain protection during temporary focal ischemia and reperfusion. He has used advanced magnetic resonance imaging techniques in the study of diffusion and perfusion and spectroscopic imaging to detect thresholds of viability. More recently, he has become involved in molecular biologic approaches to mechanisms of ischemic neuronal injury in the brain and spinal cord and the study of impairment of blood flow regulation.
