Multiple problems associated with the fixation have been described, including lesions of the suprascapular nerve due to prominence of the screw or bicortical drilling. The purpose of the present study was to evaluate whether monocortical fixation, without perforating the posterior glenoid cortex, would provide sufficient graft stability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Coracoid transfer was performed in 14 scapula models (Sawbones<jats:sup>\u00ae<\/jats:sup>, Composite Scapula, 4th generation). Two groups were assigned: in one group, fixation was achieved with two screws that did not perforate the posterior cortex of the glenoid neck (monocortical fixation), in the other group, fixation was achieved with perforation of the posterior cortex (bicortical fixation). The ultimate failure load and mode of failure were evaluated biomechanically.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Monocortical fixation was a significantly weaker construct than bicortical fixation (median failure load 221\u00a0N, interquartile range 211\u2013297 vs. median failure load 423\u00a0N, interquartile range 273\u2013497; <jats:italic>p<\/jats:italic>\u2009=\u20090.017). Failure was either due to a pullout of the screws from the socket or a fracture of the glenoid. There was no significant difference in the mode of failure between the two groups (n.s.).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Monocortical fixation was significantly weaker than bicortical fixation. However, bicortical drilling and overly long screws may jeopardize the suprascapular nerve. Thus, anatomic knowledge about the safe zone at the posterior rim of the glenoid is crucial. Until further research has evaluated, if the inferior stability is clinically relevant, clinicians should be cautious to use a monocortical fixation technique for the coracoid graft.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-018-4837-2","type":"journal-article","created":{"date-parts":[[2018,1,13]],"date-time":"2018-01-13T09:59:47Z","timestamp":1515837587000},"page":"239-244","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Monocortical fixation of the coracoid in the Latarjet procedure is significantly weaker than bicortical fixation"],"prefix":"10.1002","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2898-2934","authenticated-orcid":false,"given":"Uli","family":"Schmiddem","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Trauma Department Hannover Medical School Carl\u2010Neuberg\u2010Str. 1 30625 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nael","family":"Hawi","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Trauma Department Hannover Medical School Carl\u2010Neuberg\u2010Str. 1 30625 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emmanouil","family":"Liodakis","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Trauma Department Hannover Medical School Carl\u2010Neuberg\u2010Str. 1 30625 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonios","family":"Dratzidis","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Trauma Department Hannover Medical School Carl\u2010Neuberg\u2010Str. 1 30625 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel","family":"Kraemer","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Laboratory of Biomechanics and Biomaterials Hannover Medical School Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christof","family":"Hurschler","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Laboratory of Biomechanics and Biomaterials Hannover Medical School Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Page","sequence":"additional","affiliation":[{"name":"<!--<label>3<\/label>--> Orthopaedic Department, St. John of God Hospital and University Hospital Geelong, School of Medicine Deakin University Geelong Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rupert","family":"Meller","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Trauma Department Hannover Medical School Carl\u2010Neuberg\u2010Str. 1 30625 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,1,13]]},"reference":[{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/2325967116643533"},{"key":"e_1_2_9_3_2","doi-asserted-by":"crossref","unstructured":"AnVV SivakumarBS PhanK TrantalisJA systematic review and meta\u2010analysis of clinical and patient\u2010reported outcomes following two procedures for recurrent traumatic anterior instability of the shoulder: Latarjet procedure vs. Bankart repair.J Shoulder Elbow Surg(2016)10.1016\/j.jse.2015.11.00127727059","DOI":"10.1016\/j.jse.2015.11.001"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2010.01.011"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0749\u20108063(90)90060\u2010Q"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2015.06.001"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2010.07.011"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999\u2010014\u20103691\u2010x"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2012.02.008"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010015\u20103551\u20106"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301\u2010620X.98B9.37948"},{"key":"e_1_2_9_12_2","unstructured":"GartsmanGM WaggenspackWNJr O\u2019ConnorDP ElkousyHA EdwardsTBImmediate and early complications of the open Latarjet procedure: a retrospective review of a large consecutive case series.J Shoulder Elbow Surg(2016)2751463210.1016\/j.jse.2016.05.029"},{"key":"e_1_2_9_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2016.06.016"},{"key":"e_1_2_9_14_2","doi-asserted-by":"publisher","DOI":"10.1590\/S1413\u201078522013000300002"},{"key":"e_1_2_9_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2012.09.009"},{"key":"e_1_2_9_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2012.11.003"},{"key":"e_1_2_9_17_2","unstructured":"HardyA GeromettaA GrangerB MasseinA CasabiancaL Pascal\u2010MoussellardHet al.
