    Collapse Overview
    Dr. Lee Tan specializes in both minimally invasive and traditional open surgical techniques for the treatment of various spinal disorders. His clinical focus includes spinal deformities (scoliosis, kyphosis, “flat-back” syndrome, “chin-on-chest” deformity), cervical spine pathologies (cervical disc herniation, cervical stenosis, OPLL), and degenerative lumbar spine pathologies (disc herniation, spinal stenosis, spondylolisthesis). He also has expertise in robotic spine surgery, as well as motion-preservation techniques such as cervical artificial disc replacement and cervical laminoplasty, which can lead to superior clinical outcome in well-selected patients. Another unique aspect of Dr. Tan’s training is that he received both neurosurgical and orthopedic spine surgery training, which enables him to assess spinal pathologies from an interdisciplinary perspective to select the most appropriate treatment tailored to each individual patient. Dr. Tan’s research interests include spinal deformity outcome, motion preservation techniques, robotic spine surgery, minimally invasive techniques, and spinal cord injury.
