However, cases of contralateral wire migration are rare. We present a case of contralateral loosened Kirschner wire migration from the right acromioclavicular joint to the left side of the neck without damage to any important structures or great vessels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case presentation<\/jats:title><jats:p>We report a case of a loosened Kirschner wire migrating from the right acromioclavicular joint to the left side of the neck in a 34-year-old Taiwanese man following a route of transversal, descendant, and then ascendant directions. The Kirschner wire was removed by exploratory neck dissection under C-arm fluoroscopy assistance without complication.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Wire migration may occur after surgical treatment with or without clinical complaint. Several hypotheses for the mechanism of wire migration have been postulated, including muscular activity, respiratory motion, gravity, and motion of upper extremity. Therefore, the importance of follow-up should be communicated to the patient. Once wire loosening or migration is noted, the implant should be removed immediately under intraoperative C-arm fluoroscopy or ultrasound assistance.<\/jats:p><\/jats:sec>","DOI":"10.1186\/s13256-019-2279-1","type":"journal-article","created":{"date-parts":[[2019,12,11]],"date-time":"2019-12-11T01:03:29Z","timestamp":1576026209000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Contralateral migration of Kirschner wire from right acromioclavicular joint to left side of neck: a case report"],"prefix":"10.1186","volume":"13","author":[{"given":"How-Yun","family":"Ko","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ka-Wo","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,12,11]]},"reference":[{"issue":"21","key":"2279_CR1","doi-asserted-by":"publisher","first-page":"e3741","DOI":"10.1097\/MD.0000000000003741","volume":"95","author":"L Tan","year":"2016","unstructured":"Tan L, Sun DH, Yu T, Wang L, Zhu D, Li YH.
