Currently, arthroscopy is most frequently used to assist insertion of a retrograde guide wire for a retrograde cannulated screw. The present anatomical study presents an innovative arthroscopic technique to introduce an antegrade guide wire from an accessory anteromedial portal and evaluates its safety and reproducibility.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Six fresh\u2010frozen cadaver specimens were obtained and prepared to mimic an arthroscopic setting. The coronoid process was localized and a 0.9\u00a0mm Kirschner wire was introduced from an accessory anteromedial portal, located 2\u00a0cm proximal to the standard anteromedial portal. At the end of the procedure, a lateral radiograph was taken to verify the Kirschner wire position and open dissection was conducted to evaluate possible damage to neurovascular structures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The Kirschner wire was drilled without complications in the coronoid process of all six specimens. Damage of the brachial artery, the median nerve, and the ulnar nerve did not occur in any specimen. A corridor between the brachialis muscle, the median intermuscular septum, and the pronator teres could be identified as suitable for the wire passage.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study presents a safe and reproducible technique combining the possibility to introduce a guide wire from the anteromedial part of the coronoid, under direct visual control, with a completely arthroscopic approach. This wire can guide the introduction of a retrograde cannulated screw from the dorsolateral ulna to the tip of the coronoid. This new arthroscopic approach permits to obtain improved visual control over coronoid process fixation, without endangering neurovascular structures.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-018-4926-2","type":"journal-article","created":{"date-parts":[[2018,4,2]],"date-time":"2018-04-02T03:53:29Z","timestamp":1522641209000},"page":"314-318","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["No neurovascular damage after creation of an accessory anteromedial portal for arthroscopic reduction and fixation of coronoid fractures"],"prefix":"10.1002","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8273-9823","authenticated-orcid":false,"given":"Paolo","family":"Arrigoni","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> 1\u00b0 Clinica Ortopedica Azienda Socio Sanitaria Territoriale Centro Specialistico Ortopedico Traumatologico Gaetano Pini\u2010CTO Piazza Cardinal Ferrari 1 20122 Milan Italy"},{"name":"<!--<label>2<\/label>--> Laboratory of Applied Biomechanics, Department of Biomedical Sciences for Health Universit\u00e0 degli Studi di Milano Via Mangiagalli 31 20133 Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6284-7977","authenticated-orcid":false,"given":"Davide","family":"Cucchi","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Laboratory of Applied Biomechanics, Department of Biomedical Sciences for Health Universit\u00e0 degli Studi di Milano Via Mangiagalli 31 20133 Milan Italy"},{"name":"<!--<label>3<\/label>--> Department of Orthopaedics and Trauma Surgery Universit\u00e4tsklinikum Bonn Sigmund\u2010Freud\u2010Str. 25 53127 Bonn Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico","family":"Guerra","sequence":"additional","affiliation":[{"name":"<!--<label>4<\/label>--> Shoulder and Elbow Unit Istituto Ortopedico Rizzoli Via Pupilli 1 40136 Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Luceri","sequence":"additional","affiliation":[{"name":"<!--<label>5<\/label>--> U.O.
