Started in 1971 by a small group of specialized orthopaedists, the society was initially very restrictive in order that the discussion of problems would be at a high level by people with a great deal of experience. It was recognized that many orthopedic surgeons who had made significant contributions to pediatric orthopedics did not necessarily limit their practice exclusively to children, however, the feeling was that membership should be based upon demonstrated interest and contributions made to the clinical management, teaching, or research in pediatric orthopedics. Although never written, there was a policy that there would only be one member from each of the well-known pediatric orthopedic institutions. This policy was a major impetus to the later establishment of the Pediatric Orthopedic Study Group since there would be little likelihood of membership for orthopedists first assistant positions at that time. The society would later merge with the POSG and eventually form the Pediatric Orthopaedic Society of North America.
