About Bassem Elhassan, MD

Dr. Elhassan joined Massachusetts General Hospital in October 2020. Before coming here, he was on the faculty at the Mayo Clinic and was a Professor of Orthopaedic Surgery at Mayo Clinic College of Medicine.

Dr. Elhassan received his medical degree at the American University of Beirut. He completed three years of training in general surgery focusing on cardiothoracic surgery and one year in orthopaedic surgery at the American University of Beirut. Dr. Elhassan went on to complete his residency in orthopaedic surgery at the University of Illinois in Chicago. While there, he received the Senior Alpha Omega Alpha Honor Medical Society, as well as the Robert Ray Award for Research. Dr. Elhassan completed a fellowship in hand and upper extremity at the Mayo Clinic and an additional fellowship in shoulder and elbow surgery at Mass General.

Dr. Elhassan started working at the Mayo Clinic in 2007. He won the Mayo Clinic Teacher of the Year Award for two consecutive years in 2009 and 2010, and his upper extremity service was voted as one of the best rotations for the Mayo Clinic’s residents and fellows.

Dr. Elhassan has been innovative in the field of upper extremity surgery and he has developed numerous novel procedures (20 new surgical procedures for the shoulder, elbow and wrist) through dedicated anatomic and biomechanical studies. The care and outcome of patients, specifically those with complex shoulder and elbow problems, improved significantly because of these innovations. He is considered the world expert in the evaluation and management of scapulothoracic disorders, and tendon transfers around the shoulder and elbow.

Dr. Elhassan has published over 125 peer-reviewed articles and authored thirty book chapters. He has presented at countless meetings both nationally, as well as internationally, and he has won numerous awards for best abstract, paper, poster, video and podium presentation in national and international hand and shoulder and elbow societies. He is also the recipient of the 2015 ASES Traveling Fellowship Exchange Program.

Research

Dr. Elhassan's main research is focused on understanding the anatomy and biomechanics of the shoulder. He was able, with the help of his colleagues, to create a state-of-the-art shoulder model to conduct his studies on. This model has helped in the evaluation of the kinematics of the scapula and the scapulothoracic articulation. In addition, it helped determine the effectiveness of different muscle transfers to reconstruct the deficient rotator cuff, in native shoulders as well as in shoulders with reverse shoulder arthroplasty.
