Spine Surgery Program

The University of Michigan Spine Surgery Program provides state-of-the-art, comprehensive, patient-centered services to individuals affected by spinal disorders that may require surgical intervention. Patients referred to the spine surgery program may suffer from significant pain, weakness, numbness, and tingling due to degenerative disc disease, disc herniation, stenosis, spondylolisthesis, scoliosis, spinal tumor, or traumatic injury.

We offer a broad spectrum of advanced therapeutic options performed by experienced, fellowship trained experts in the field of spinal surgery. Surgeons in the Department of Neurosurgery also work closely with colleagues in the Department of Physical Medicine and Rehabilitation, Department of Anesthesiology Pain and the Department of Orthopaedic Surgery to ensure that each patient receives optimal surgical or medical therapy for their spine problem.

Surgical treatment options may range from outpatient minimally invasive procedures such as discectomy, laminotomy, kyphoplasty/vertebroplasty to minimally invasive fusion and artificial spinal disk surgery in addition to more complex surgeries including multi-level instrumentation and fusion for traumatic fracture stabilization, spinal deformity correction, and resection of tumors. Each therapy is custom-tailored to suit the individual patient’s specific condition. With such a broad array of treatment options, the program takes pride in its ability to provide comprehensive care in a compassionate and informed manner.

Jacob Joseph, M.D.

Clinical Assistant Professor, Neurological Surgery
Clinical Assistant Professor, Emergency Medicine
Adjunct Research Assistant Professor, Kinesiology

Dr. Joseph’s clinical interests are in the prevention, diagnosis, and treatment of traumatic brain injury (TBI), concussion, and spinal cord injury. He is also dedicated to the treatment of patients with spinal disorders requiring complex spinal reconstructive surgery or minimally invasive spinal surgery. His research focuses on understanding the biomechanics of traumatic brain injury in sports, diagnosing concussion using novel biomarkers and imaging techniques, and developing new therapeutics for victims of TBI and spinal cord injury. Dr. Joseph serves as an Unaffiliated Neurotrauma Consultant for the National Football League and is committed to the prevention of brain and spine injuries in athletes.

Nicholas Szerlip, M.D.

Director, Spine Oncology
Clinical Associate Professor, Neurological Surgery

Dr. Nick Szerlip is originally from New York, just north of Manhattan, but lived many places around the country while growing up.  He obtained a bachelor’s degree in Psychology from Columbia University and then attended Tulane University School of Medicine in New Orleans, where he obtained his medical degree. Dr. Szerlip completed his residency training in at the University of Maryland in Baltimore. He completed additional fellowship training at the National Institutes of Health (NIH), where he examined the origins of cancer cells and effective drug delivery to treat cancer, followed by a fellowship in neurosurgical oncology at Memorial Sloan Kettering Cancer Center in New York.

Clinically, Dr. Szerlip specializes in surgical and radiation treatment of spine tumors. His goal at the University of Michigan is to continue to build a clinical and translational spine oncology program that will enable the clinic and the laboratory to work together as partners to rapidly advance care for spine cancer.  This model will foster synergy among physicians and researchers, affording patients access to the latest clinical trials and outstanding, compassionate care; it will also accelerate new therapies for future patients.
