Dr. Dean G. Lorich is the Associate Director of the Orthopaedic Trauma Service at Hospital for Special Surgery and the Chief of the Orthopaedic Trauma Service at NewYork-Presbyterian Hospital. In addition, he is an Associate Professor of Orthopaedic Surgery at Weill Cornell Medical College and a member of the teaching faculty of the AO/ASIF. He has specialized in orthopaedic trauma for the past 18 years, and his areas of expertise are complex intra-articular fractures of the tibial plateau, proximal humerus, elbow and ankle.

He obtained both his undergraduate and medical degrees at the University of Pennsylvania. After completing his residency at the Hospital of the University of Pennsylvania in 1995, Dr. Lorich completed a fellowship in Orthopaedic Trauma at Hospital for Special Surgery in 1996. Dr. Lorich was selected for the prestigious Martin Allgower Traveling Trauma Fellowship in Bern, Switzerland under Rheinhold Ganz, MD and Christian Krettek, MD in Hanover, Germany. He continues to be actively involved in orthopaedic research while lecturing nationally and abroad. Most recently, he volunteered to operate on soldiers injured in combat who were medevaced to Lansthal, Germany. He also led a relief effort in Haiti for the 2010 earthquake victims.

Dr. Lorich has published and lectured in depth on orthopaedic trauma, with an emphasis on intra-articular fractures, orthopaedic treatment of polytrauma patients, and orthopaedic care of geriatric fractures, particularly of the hip and wrist.

Dr. Lorich was recruited to Hospital for Special Surgery from the Albert Einstein School of Medicine, where he was the Director of Orthopaedics for five years. Throughout his career at HSS, he has served as a mentor in the Orthopaedic Trauma Residency Program. Dr. Lorich’s cases are presented bi-weekly at orthopaedic trauma conferences, which provide a forum for surgeons-in-training to discuss the new and innovative surgical techniques used to treat fractures.
