The American Osteopathic Board of Orthopedic Surgery (AOBOS) is an organization that provides board certification to qualified Doctors of Osteopathic Medicine (DO) and non-osteopathic physicians who specialize in the medical and surgical treatment of disorders of the musculoskeletal system. The board is one of 16 medical specialty certifying boards of the American Osteopathic Association Bureau of Osteopathic Specialists approved by the American Osteopathic Association (AOA), and was originally a subdivision of the American Osteopathic Board of Surgery until it became an independent board in 1978. Additionally, diplomates of the American Osteopathic Board of Orthopedic Surgery are eligible for membership in the American Osteopathic Academy of Orthopedics and the American Academy of Orthopaedic Surgeons.
