We hypothesized that\n\t\t\t\t\tinjuries to the lateral aspect of the coronoid process regularly involve the\n\t\t\t\t\tannular ligament insertion at the anterior lesser sigmoid notch.<\/jats:p><jats:p>\n          Material and Methods Patients treated for a coronoid process fracture at\n\t\t\t\t\tour institution between 06\/2011 and 07\/2018 were included. We excluded patients\n\t\t\t\t\t&lt;\u200918 years, patients with arthritic changes or previous operative treatment\n\t\t\t\t\tto the elbow, and patients with concomitant injuries to the proximal ulna. In\n\t\t\t\t\tpatients with involvement of the lesser sigmoid notch, the coronoid height and\n\t\t\t\t\tfragment size (anteroposterior, mediolateral, and craniocaudal) were\n\t\t\t\t\tmeasured.<\/jats:p><jats:p>\n          Results Seventy-two patients (mean age: 47 years\u2009\u00b1\u200917.6) could be included\n\t\t\t\t\tin the study. Twenty-one patients (29.2%) had a fracture involving the lateral\n\t\t\t\t\tsigmoid notch. The mean anteroposterior fragment length was 7\u2009\u00b1\u20091.6\u2009mm. The\n\t\t\t\t\tfragment affected a mean of 43\u2009\u00b1\u200910.8% of the coronoid height. The mean\n\t\t\t\t\tmediolateral size of the fragment was 10\u2009\u00b1\u20095.0\u2009mm, and the mean cranio-caudal\n\t\t\t\t\tsize was 7\u2009\u00b1\u20092.7\u2009mm.<\/jats:p><jats:p>\n          Conclusion Coronoid fractures regularly include the lesser sigmoid notch.\n\t\t\t\t\tThese injuries possibly affect the anterior annular ligament insertion which is\n\t\t\t\t\timportant for the stability of the proximal radioulnar joint and varus stability\n\t\t\t\t\tof the elbow.<\/jats:p>","DOI":"10.1055\/a-1263-1742","type":"journal-article","created":{"date-parts":[[2020,10,16]],"date-time":"2020-10-16T00:10:56Z","timestamp":1602807056000},"page":"35-39","source":"Crossref","is-referenced-by-count":2,"title":["Injuries to the Coronoid Process of the Ulna with Involvement of the\n\t\t\t\t\tLesser Sigmoid Notch"],"prefix":"10.1055","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7987-5173","authenticated-orcid":false,"given":"Valentin","family":"Rausch","sequence":"additional","affiliation":[{"name":"Center for Orthopedic and Trauma Surgery, University of Cologne,\n\t\t\t\t\tFaculty of Medicine and University Hospital, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sina","family":"Neugebauer","sequence":"additional","affiliation":[{"name":"Center for Orthopedic and Trauma Surgery, University of Cologne,\n\t\t\t\t\tFaculty of Medicine and University Hospital, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim","family":"Leschinger","sequence":"additional","affiliation":[{"name":"Center for Orthopedic and Trauma Surgery, University of Cologne,\n\t\t\t\t\tFaculty of Medicine and University Hospital, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Center for Orthopedic and Trauma Surgery, University of Cologne,\n\t\t\t\t\tFaculty of Medicine and University Hospital, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kilian","family":"Wegmann","sequence":"additional","affiliation":[{"name":"Center for Orthopedic and Trauma Surgery, University of Cologne,\n\t\t\t\t\tFaculty of Medicine and University Hospital, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Hackl","sequence":"additional","affiliation":[{"name":"Center for Orthopedic and Trauma Surgery, University of Cologne,\n\t\t\t\t\tFaculty of Medicine and University Hospital, Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,10,15]]},"reference":[{"issue":"S 01","key":"ref1","doi-asserted-by":"crossref","first-page":"174S","DOI":"10.1016\/j.jse.2004.09.031","article-title":"Stability of the elbow: osseous constraints","volume":"14","author":"B F Morrey","year":"2005","journal-title":"J Shoulder Elbow Surg"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"1749","DOI":"10.2106\/00004623-200012000-00009","article-title":"The role of the coronoid process in elbow stability.
