Bobby Tay, MD
Professor
Orthopaedic Surgery
School of Medicine

He has extensive experience in minimally invasive cervical surgery, cervical disc herniation’s, and spinal stenosis, cervical disc replacement, and complex cervical reconstruction for both decompressions of the spinal cord and realignment of the spinal column.

Dr. Tay was the principal investigator of the multicenter clinical trial on the Prodisc-c cervical disc replacement and also has one of the largest clinical experiences with endoscopic cervical decompression, both of which are used to potentially minimize or eliminate the need for spinal fusion. He enjoys both the conservative and operative management of cervical disorders and works with the best physiatrists and physical therapists in the region. In addition to cervical disorders, Dr. Tay also treats both degenerative disorders of the lumbar spine, spinal deformity, and spinal trauma
