For persisting instability, surgery is indicated to prevent chronic posterolateral rotatory instability. After lateral collateral ligament (LCL) complex repair the repair is protected by temporary immobilization, limited range of motion and hinged bracing. Internal bracing is an operative alternative augmenting the LCL repair using non\u2010absorbable suture tapes. However, the stability of LCL repair with and without additional augmentation remains unclear. The hypothesis was that LCL repair with additional suture tape augmentation would improve load to failure. Secondary goal of this study was to evaluate different humeral fixation techniques. A humeral fixation using separate anchors for the LCL repair and the augmentation was not expected to provide superior stability compared to using only one single anchor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Twenty\u2010one elbows were tested. A cyclic varus rotational torque of 0.5\u20133.5\u00a0Nm was applied in 90\u00b0, 60\u00b0, 30\u00b0, and 120\u00b0 elbow flexion to the intact, torn, and repaired LCLs. The specimens were randomized into three groups: repair alone (group I), repair with additional internal bracing using two anchors (group II), repair using one humeral anchor (group III). A load\u2010to\u2010failure protocol was conducted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Load to failure was significantly higher in groups II (26.6\u00a0Nm;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.017) and III (23.18\u00a0Nm;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.038) than in group I (12.13\u00a0Nm). No significant difference was observed between group II and III. All specimens lost reduction after LCL dissection by a mean of 4.48\u00b0\u2009\u00b1\u20094.99\u00b0 (range 0.66\u201315.82). The mean reduction gain after repair was 7.21\u00b0\u2009\u00b1\u20094.97\u00b0 (2.70\u201321.23; mean over reduction, 2.73\u00b0). The laxity was comparable between the intact and repaired LCLs (\n                      <jats:italic>n.s<\/jats:italic>\n                      .), except for varus movements at 30\u00b0 in group II (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.035) and 30\u00b0 (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.001) and 120\u00b0 in group III (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.008) with significantly less laxity. Inserting the ulnar suture anchor showed failure in the thread in 10 cases.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>LCL repair with additional internal bracing yielded higher load to failure than repair alone. Repair with additional internal bracing for the humeral side using one anchor was sufficient. A higher primary stability would facilitate postoperative management and allow immediate functional treatment. Reducing the number of humeral anchors would save costs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00167-020-05918-5","type":"journal-article","created":{"date-parts":[[2020,3,11]],"date-time":"2020-03-11T02:02:40Z","timestamp":1583892160000},"page":"284-291","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Suture tape augmentation of the lateral ulnar collateral ligament increases load to failure in simulated posterolateral rotatory instability"],"prefix":"10.1002","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6055-4249","authenticated-orcid":false,"given":"Alexander","family":"Ellwein","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedic Surgery, Medical School Hannover DIAKOVERE Annastift Anna\u2010von\u2010Borries\u2010Stra\u00dfe 1\u20107 30625 Hannover Germany"},{"name":"<!--<label>2<\/label>--> Department of Orthopedic Surgery and Traumatology DIAKOVERE Friederikenstift Humboldtstr. 5 30169 Hannover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"F\u00fc\u00dfler","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedic Surgery, Medical School Hannover DIAKOVERE Annastift Anna\u2010von\u2010Borries\u2010Stra\u00dfe 1\u20107 30625 Hannover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel","family":"Ferle","sequence":"additional","affiliation":[{"name":"<!--<label>3<\/label>--> Laboratory of Biomechanics and Biomaterials Medical School Hannover 30625 Hannover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomas","family":"Smith","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedic Surgery, Medical School Hannover DIAKOVERE Annastift Anna\u2010von\u2010Borries\u2010Stra\u00dfe 1\u20107 30625 Hannover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helmut","family":"Lill","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Department of Orthopedic Surgery and Traumatology DIAKOVERE Friederikenstift Humboldtstr. 5 30169 Hannover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc\u2010Frederic","family":"Pastor","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedic Surgery, Medical School Hannover DIAKOVERE Annastift Anna\u2010von\u2010Borries\u2010Stra\u00dfe 1\u20107 30625 Hannover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,3,11]]},"reference":[{"key":"e_1_2_10_2_2","first-page":"311","article-title":"The treatment of simple elbow dislocation in adults\u2014a systematic review","volume":"112","author":"Hackl M","year":"2015","journal-title":"Dtsch Arztebl Int"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports\u20102015\u2010094704"},{"key":"e_1_2_10_4_2","first-page":"272","article-title":"Pure posterior luxation of the elbow in adults: immobilization or early mobilization.
