The procedure involves exposure of the posterior elbow joint as well creating a window posteriorly through the olecranon fossa to target anterior aspects of the elbow. Several case series have shown the O\u2010K procedure to have good functional outcomes with minimal complications. Used mostly for the surgical treatment of adult osteoarthritis, the O\u2010K procedure has not been previously described for the treatment of a pediatric supracondylar humerus fracture malunion. This article and accompanying video will present the pearls and discuss the technique of the O\u2010K procedure used to treat the loss of elbow flexion as a sequelae of supracondylar humerus fracture malunion.<\/jats:p>\n <\/jats:sec>\n \n Technique Video<\/jats:title>\n \n \n \n video<\/jats:alt-text>\n <\/jats:graphic>\n <\/jats:boxed-text>\n <\/jats:p>\n \n See video under supplementary data.<\/jats:bold>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1016\/j.eats.2019.11.002","type":"journal-article","created":{"date-parts":[[2020,2,7]],"date-time":"2020-02-07T08:15:43Z","timestamp":1581063343000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":6,"title":["Outerbridge\u2010Kashiwagi Procedure for the Treatment of a Supracondylar Humerus Fracture Malunion (O\u2010K Procedure)"],"prefix":"10.1002","volume":"9","author":[{"given":"Rami George","family":"Alrabaa","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery Columbia University Medical Center New York New York U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Simhon","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Columbia University Medical Center New York New York U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
