Ulnar osteotomy is an effective treatment method. This article reports a case of chronic Monteggia fracture in an 11-year-old male patient successfully treated with a simple proximal ulnar osteotomy.</abstract><keywords/></article-meta></front><body/><back><ref-list><ref id="B1" content-type="article"><label>1</label><element-citation publication-type="journal"><p>Tan J, 2009, Clinical Pathological Findings and Finite Element Model Analysis of the Annular Ligament in Monteggia Fractures, thesis, Shandong University.</p><pub-id pub-id-type="doi"/></element-citation></ref><ref id="B2" content-type="article"><label>2</label><element-citation publication-type="journal"><p>Soni J, Valenza W, Pavelec A, 2019, Chronic Monteggia.
