Hospital for Special Surgery (HSS), the world's leading academic medical center focused on musculoskeletal health, today announced the appointments of David J. Mayman, MD, as chief of the Adult Reconstruction and Joint Replacement (ARJR) Service and Daniel W. Green, MD, MS, as chief of the Pediatric Orthopedic Surgery Service.

Dr. Mayman will succeed Mathias P. Bostrom, MD, who, along with sports medicine surgeon Answorth A. Allen, MD, was recently appointed Associate Surgeon-in-Chief at HSS after serving as ARJR chief for the past four years. Dr. Green will succeed Roger F. Widmann, MD, who has led the Pediatric Surgical Service since 2004. Dr. Widmann will continue to care for pediatric patients with spine and limb deformities and will lead a new center of excellence dedicated to robotic-assisted surgery at HSS. Both appointments will go into effect September 5.

“We are grateful to Drs. Bostrom and Widmann for their steadfast leadership over the years,” said Bryan T. Kelly, MD, MBA, president, surgeon-in-chief and medical director of HSS. “Drs. Mayman and Green are not only talented surgeons, they are collaborative leaders who bring a wealth of expertise and experience to their new roles. These appointments will allow us to continue to advance excellence for our joint replacement and pediatric surgical patients.”

In their new roles, Drs. Mayman and Green will each lead highly integrated multidisciplinary teams. The ARJR service is comprised of programs focused on hip and knee osteoarthritis and other problems requiring joint replacement in adults, while Pediatrics covers the spectrum of conditions requiring orthopedic surgery in children, ranging from sports medicine injuries and trauma to congenital issues of the spine and hip.
