Imaging obtained was consistent with distal clavicle osteochondromas with mass effect onto the superior rotator cuff. Staged bilateral open resection was performed with resolution of symptoms without recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Langer-Giedion syndrome characteristically includes multiple exostoses. These are rarely found in the lateral clavicle, but when present can become symptomatic impinging upon the underlying supraspinatus and causing inflammation of the subacromial bursa due to extrinsic mechanical irritation. This is the first case report to discuss symptomatic bilateral lesions with successful treatment through open resection.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.25.00365","type":"journal-article","created":{"date-parts":[[2026,2,5]],"date-time":"2026-02-05T19:00:58Z","timestamp":1770318058000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Bilateral Distal Clavicle Osteochondromas in Langer-Giedion Syndrome Leading to Subacromial Impingement"],"prefix":"10.2106","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7621-7674","authenticated-orcid":false,"given":"Lauren","family":"Swany","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, University of Michigan, Ann Arbor, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7620-426X","authenticated-orcid":false,"given":"William R.","family":"Aibinder","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University of Michigan, Ann Arbor, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,1]]},"reference":[{"issue":"5","key":"bib1-20260205","first-page":"656","article-title":"Langer-Giedion syndrome: a distinct phenotype","volume":"24","author":"George","year":"2014","journal-title":"Iran J Pediatr."},{"issue":"8","key":"bib2-20260205","first-page":"e24.00010","article-title":"Trichorhinophalangeal syndrome orthopaedic manifestations and management: a systematic review","volume":"8","author":"Ellison","year":"2024","journal-title":"J Am Acad Orthop Surg Glob Res Rev."},{"issue":"2","key":"bib3-20260205","doi-asserted-by":"crossref","first-page":"681","DOI":"10.21873\/invivo.12308","article-title":"Osteochondromas: an updated review of epidemiology, pathogenesis, clinical presentation, radiological features and treatment options","volume":"35","author":"Tepelenis","year":"2021","journal-title":"In Vivo."},{"issue":"10","key":"bib4-20260205","first-page":"807","article-title":"Osteochondroma of the distal clavicle: an unusual cause of rotator cuff impingement","volume":"29","author":"Reichmister","year":"2000","journal-title":"Am J Orthop."},{"issue":"6","key":"bib5-20260205","first-page":"50","article-title":"Clavicular osteochondroma: extremely rare cause of impingement syndrome","volume":"8","author":"Simonetti","year":"2018","journal-title":"J Orthop Case Rep."},{"issue":"1","key":"bib6-20260205","first-page":"96","article-title":"Impingement syndrome because of an osteochondroma lesion of the distal clavicle","volume":"4","author":"Afshar","year":"2024","journal-title":"JSES Rev Rep Tech."},{"key":"bib7-20260205","doi-asserted-by":"crossref","first-page":"103003","DOI":"10.1016\/j.amsu.2021.103003","article-title":"Shoulder impingement caused by distal clavicle osteochondroma","volume":"72","author":"Almogbil","year":"2021","journal-title":"Ann Med Surg (Lond)."},{"issue":"4","key":"bib8-20260205","first-page":"e4354","article-title":"Distal clavicle osteochondroma causing supraspinatus tendinopathy","volume":"11","author":"Galanopoulos","year":"2019","journal-title":"Cureus."},{"issue":"suppl 1","key":"bib9-20260205","first-page":"8683","article-title":"Arthroscopic treatment of an unusual distal clavicle osteochondroma causing rotator cuff impingement: case report and literature review","volume":"12","author":"Messinese","year":"2020","journal-title":"Orthop Rev (Pavia)."},{"issue":"3","key":"bib10-20260205","doi-asserted-by":"crossref","first-page":"158","DOI":"10.5397\/cise.2018.21.3.158","article-title":"Osteochondroma of the distal clavicle: a rare cause of impingement and biceps tear of the shoulder","volume":"21","author":"Kim","year":"2018","journal-title":"Clin Shoulder Elb."}],"container-title":["JBJS Case Connector"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.2106\/JBJS.CC.25.00365","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T13:37:41Z","timestamp":1787751461000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.2106\/JBJS.CC.25.00365"}},"subtitle":["A Case Report"],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":10,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.2106\/jbjs.cc.25.00365","relation":{},"ISSN":["2160-3251"],"issn-type":[{"value":"2160-3251","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]}}}
