Due to its rarity, there is no consensus on optimal management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>A 43\u2010year\u2010old male sustained a right shoulder injury during a snowboarding accident. Imaging revealed a right\u2010sided AC joint dislocation with minimal superior displacement (coracoclavicular [CC] distance 13.6\u2009mm on the right vs. 12\u2009mm contralaterally) and a base\u2010near coracoid fracture (Ogawa Type I and Eyres Type IV). Clinical examination showed clavicular elevation and tenderness over the AC joint, with preserved neurovascular function. Surgical management included AC joint stabilization with a short hook plate and screw osteosynthesis of the coracoid fracture. Postoperative care involved immobilization in a functional brace with staged passive and active\u2010assisted range\u2010of\u2010motion exercises, progressing to strengthening from Week 12.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Outcome and Follow\u2010Up<\/jats:title>\n                    <jats:p>At 6 and 12 weeks, radiographs confirmed maintained reduction and fracture healing. The hook plate was removed 3.5 months postoperatively. Follow\u2010up 6 weeks later demonstrated a healed coracoid base, congruent AC joint, minimal pain, and good shoulder function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Surgical fixation restores biomechanical integrity of the SSSC and allows early functional rehabilitation. Combined AC and coracoid fixation represent a viable option, though isolated AC stabilization may also yield favorable outcomes if intraoperative imaging confirms adequate indirect reduction of the coracoid fracture. In our opinion, combined fixation provides a very stable construct with the best chances for anatomical healing and restoration of SSSC integrity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Concurrent AC dislocation and coracoid fracture is a rare injury that requires careful diagnostic assessment, as the coracoid fracture may be overlooked on conventional imaging. This case demonstrates that surgical management with AC stabilization using a hook plate and coracoid screw fixation can achieve excellent radiological and clinical outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/cro\/5181452","type":"journal-article","created":{"date-parts":[[2026,4,6]],"date-time":"2026-04-06T10:16:47Z","timestamp":1775470607000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An Unusual Pattern of Acromioclavicular Joint Instability With Coracoid Base Fracture"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1424-1292","authenticated-orcid":false,"given":"Mara","family":"Dimitriu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4485-0256","authenticated-orcid":false,"given":"Markus","family":"Scheibel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9416-138X","authenticated-orcid":false,"given":"Florian","family":"Freislederer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,6]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.5312\/wjo.v8.i12.861"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.3238\/arztebl.2019.0089"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0b013e318184205c"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.79B1.0790017"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199304000-00001"},{"key":"e_1_2_12_6_2","first-page":"333","volume-title":"The Shoulder","author":"Goss T.
