Dr. Baron Lonner is a Professor of Orthopedic Surgery at Mount Sinai Hospital in New York City. Dr. Lonner’s central clinical interest is caring for patients with scoliosis and other spinal deformities using both operative and nonoperative treatments.

With over 120 publications in the orthopedic literature, Dr. Lonner’s research interests include outcomes in spinal deformity surgery and nonoperative care. He and his team have developed two new outcome instruments for adolescent idiopathic scoliosis.

He is a reviewer for four spine journals, and he is an associate editor on the editorial board of the Journal of Spinal Deformity.
