We aimed to identify negative prognostic factors for unfavorable outcomes following olecranon fractures. <\/jats:p><jats:p> Methods: We retrospectively reviewed the records of 100 patients with olecranon fractures and collected data on the conducted procedures, age, fracture condition, postoperative reduced position, and postoperative active range of motion (AROM) of the elbow joint. The primary outcome was the regaining of an AROM of &gt; 130\u00b0 flexion and &lt; \u221230\u00b0 extension of the elbow joint at the final follow-up. We performed multivariate logistic regression analysis to identify the negative prognostic factors. <\/jats:p><jats:p> Results: The mean follow-up period was 11 months. All patients regained an average AROM of 121 degrees. Eighty-one patients regained a favorable AROM of the elbow joint. On univariate logistic regression analysis, diabetes mellitus (OR, 8.2; 95%CI, 1.6\u201341.7), comminution of the fractured site (OR, 23.1; 95% CI, 13.2\u2013165.0), and utilization of the tension band wiring (TBW) technique (OR, 7.5; 95% CI, 1.16\u201348.2) were significant factors in aggravating the final result of elbow AROM. On multivariate analysis, patients with diabetes mellitus (OR, 10.9; 95% CI, 2.83\u201341.9), comminuted fractures (OR, 11.4; 95% CI, 2.61\u201350.2), or undergoing the tension band wiring technique (TBW) (OR, 5.5; 95% CI, 1.35\u201350.2) showed reduced postoperative AROM of the elbow joint; postoperative malreduction of the articular surface was not a negative prognostic factor. Seven of 51 patients treated with TBW underwent revision surgery because of non-union or postoperative displacement. <\/jats:p><jats:p> Conclusions: TBW for olecranon fractures is a simple and cost-effective procedure; however, negative effects could develop when regaining sufficient postoperative AROM of the elbow joint. Therefore, rigid fixation without reoperation may lead to a favorable outcome. Postoperative malreduction does not always worsen the postoperative AROM of the elbow joint, at least not in the early postoperative period. <\/jats:p>","DOI":"10.1142\/s2424835521500090","type":"journal-article","created":{"date-parts":[[2020,12,20]],"date-time":"2020-12-20T05:16:15Z","timestamp":1608441375000},"page":"60-64","source":"Crossref","is-referenced-by-count":4,"title":["Factors Affecting the Range of Motion of the Elbow after Open Reduction of Olecranon Fractures"],"prefix":"10.1142","volume":"26","author":[{"given":"Yuki","family":"Fujihara","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Nagoya Ekisaikai Hospital, Nagoya, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideyuki","family":"Ota","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Nagoya Ekisaikai Hospital, Nagoya, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Nagoya Ekisaikai Hospital, Nagoya, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2020,12,16]]},"container-title":["The Journal of Hand Surgery (Asian-Pacific Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S2424835521500090","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,2,9]],"date-time":"2021-02-09T12:49:05Z","timestamp":1612874945000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S2424835521500090"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,12,16]]},"references-count":0,"journal-issue":{"issue":"01","published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1142\/S2424835521500090"],"URL":"https:\/\/doi.org\/10.1142\/s2424835521500090","relation":{},"ISSN":["2424-8355","2424-8363"],"issn-type":[{"value":"2424-8355","type":"print"},{"value":"2424-8363","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,12,16]]}}}
