Dr. Perri's clinical specialty and interests is reconstructive surgery for spinal tumors and deformities, as well as micro/minimal invasive surgery and motion preservation surgery for degenerative spinal diseases.
Dr. Perri's areas of research interest have involved traumatic brain and spinal cord injury and subsequent neuroprotective and recovery therapies. He has presented his findings at numerous national and international conferences, including the AANS/CNS Joint Section on Disorder of the Spine and Peripheral Nerves, International Meeting for Traumatic Brain Injury and the Richard Lende Winter Neurosurgery Conference, as well as meetings of the Cervical Spine Research Society, North American Spine Society and Traumatic Brain Injury Society. Dr. Perri has also presented his recent research on the artificial disc replacement and potential postoperative complications, and his work on developing a classification system for cervical kyphotic deformities with strategies and techniques for surgical reconstruction.
Khawar Siddique, MD is a neurosurgeon who specializes in spinal disorders. He treats many conditions in the cervical, thoracic, and lumbar spine. Special interests include spinal tumors, advanced minimally invasive approaches (such as percutaneous decompressions and fusions), cervical spine deformity, Chiari decompressions, novel cervical fusion techniques, and lumbar deformity. He has experience in many new spinal procedures, including motion preservation technology (artificial disk replacements and “soft” stabilization procedures), minimally invasive decompressions and fusions, and image-guided spine surgery.
His research interests include spinal cord injury, models of spinal metastatic tumors and traumatic brain injuries. He is currently Principal Investigator at Cedars-Sinai Medical Center for the Duragen IDE trial on reduction of post-operative scarring after lumbar diskectomy.
Board eligible for the American Board of Neurological Surgery, Dr. Siddique is a member of the American Association of Neurological Surgeons, American Association for Cancer Research and Congress of Neurological Surgeons. He has written many articles and book chapters for peer-reviewed publications, including Journal of Neurosurgery, Neurosurgical Focus, Oncogene, and International Journal of Oncology.
