In the current and previous decade, the literature has focused on the debate concerning the open and arthroscopic Latarjet procedure, and has supported this intervention to solve three main problems: glenoid bone loss, an engaging Hill-Sachs lesion and capsular insufficiency. The results for this procedure of recurrences at medium- and long-term follow up were between 0 and 5% (Alvi et al., 2016; Degen et al., 2016; Kleiner et al., 2016; Lafosse et al., 2007; An et al., 2016; Cassagnaud et al., 2003; Matton et al., 1992; Russo et al., 1990; Russo et al., 1998; Torg et al., 1987; Di Giacomo et al., 2011; Kany et al., 2016; Ramhamadany & Modi, 2016). This technique can be considered a non-anatomical procedure and is not without risks. Furthermore, results regarding the percentage of coracoid bone graft healing and the incidence of secondary gleno-humeral osteoarthritis seem to be less favorable. In particular, increased use of the arthroscopic Latarjet technique would increase peri-operative and post-operative complications to between 20% and 40% (Griesser et al., 2013). That is why other solutions are being considered to overcome the inherent technical difficulties in transferring the coracoid graft onto the glenoid (Matton et al., 1992; Di Giacomo et al., 2011; Athwal et al., 2016; Gartsman et al., 2017; Guity et al., 2002; Randelli et al., 2016; Young & Rockwood, 1991). A novel, all-arthroscopic technique using three cortical free bone grafts has been described using 4 buttons to stabilize the graft from back to front to avoid complications related to anterior screw fixation and anatomical modification of the coracoacromial arch (Taverna et al., 2008; Taverna et al., 2014). For our study, we chose the percentage of 25% because this is the glenoid defect size for which in literature it is well known that shoulder has to be treated with a bone block procedure because the standard anterior capsulorrhaphy is not indicated (Burkhart & De Beer, 2000; Provencher et al., 2010).
