While the occurrence of HO is well-documented, its biomechanical influence on clavicular fractures remains less explored. We present a\u00a0case report of a\u00a0patient with a\u00a0clavicular fracture following a\u00a0bicycle accident, accompanied by incidental findings of HO around the coracoclavicular (CC) ligaments.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A\u00a059-year-old man presented with a\u00a0displaced right-sided clavicular fracture and a\u00a0cervical vertebral body fracture following a\u00a0bicycle fall. Incidental findings revealed pronounced HO around the CC ligaments. The patient underwent surgical stabilization for the cervical vertebral body fracture and clavicular fracture using open reduction and internal fixation. The presence of ossified CC ligaments may influence the biomechanical considerations for clavicular fractures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The present case report suggests that ossified CC ligaments may impact clavicular biomechanics, potentially offering increased stability at the CC attachment and acting as a\u00a0protective shield during trauma. This observation may indicate a\u00a0possible predisposition to fractures in the clavicular region medial to the CC ligaments. While we cannot determine causality based on this single case, pronounced ossification of the CC ligaments could increase local stiffness and alter load distribution.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00113-026-01686-y","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T06:11:47Z","timestamp":1770876707000},"page":"276-280","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of coracoclavicular heterotopic ossifications in treatment of clavicular fractures","Einfluss heterotoper Ossifikationen im Bereich des Akromioklavikulargelenks auf die Behandlung von Klavikulafrakturen"],"prefix":"10.1007","volume":"129","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7845-2758","authenticated-orcid":false,"given":"Malik","family":"Jessen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Zehnder","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Biberthaler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chlodwig","family":"Kirchhoff","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Schwarz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"issue":"6","key":"1686_CR1","doi-asserted-by":"publisher","first-page":"1359","DOI":"10.1177\/0363546514526361","volume":"42","author":"JT Beckmann","year":"2014","unstructured":"Beckmann\u00a0JT, Wylie\u00a0JD, Kapron\u00a0AL, Hanson\u00a0JA, Maak\u00a0TG, Aoki\u00a0SK (2014) The Effect of NSAID Prophylaxis and Operative Variables on Heterotopic Ossification After Hip Arthroscopy.
