Aaron Insel, M.D., is fellowship-trained in hand & upper extremity surgery and specializes in both conservative and operative treatment of the hand, wrist, elbow, and shoulder. He completed his orthopedic surgery training at the prestigious University of Pittsburgh Medical Center. He then went on to complete his fellowship at SUNY Stony Brook where he learned from several world-renowned faculty and leaders in the field of upper extremity surgery.

Dr. Insel is skilled in several of the most advanced and minimally invasive procedures including Xiaflex® injections to treat Dupuytren’s disease, endoscopic carpal tunnel release as well as wrist arthroscopy. He also specializes in microsurgical reconstruction of injured nerves and blood vessels in the hand and upper extremity.

He treats patients of all ages from children with congenital trigger thumb to elderly individuals with arthritic joints. His particular interests include treating fractures, reconstructing arthritic joints of the shoulder, elbow and fingers, peripheral nerve disorders and tendinopathies. However, his orthopedic surgery training makes him well equipped to treat a wide range of orthopedic injuries apart from those affecting the upper extremity.

Dr. Insel is the former Section Chief of Hand Surgery at Montefiore New Rochelle Hospital. He is a member of the American Academy of Orthopaedic Surgeons (AAOS), American Society for Surgery of the Hand (ASSH), and American Association for Hand Surgery (AAHS).
