The American Academy of Orthopaedic Surgeons has developed Appropriate Use Criteria (AUC) on the Management of Pediatric Supracondylar Humerus Fractures (PSHF). Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain the best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The PSHF AUC clinical patient scenarios were derived from patient indications that generally accompany a PSHF as well as from current evidence-based clinical practice guidelines and supporting literature. The 220 patient scenarios and 14 treatments were developed by the Writing Panel, a group of clinicians who are specialists in this AUC topic. Next, the Review Panel, a separate group of volunteer physicians, independently reviewed these materials to ensure that they were representative of patient scenarios that clinicians are likely to encounter in daily practice. Finally, the multidisciplinary Voting Panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May Be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).
