Suture Button Congruent Arc Latarjet Procedure in the Treatment of Recurrent Anterior Shoulder Instability With Glenoid Bone Loss Greater Than 25.

It is generally believed that glenoid bone loss (GBL) greater than 25% can be defined as a massive GBL. For this type of recurrent anterior shoulder instability, the traditional Latarjet technique is usually inadequate to restore the GBL. Although the congruent arc Latarjet technique is able to reconstruct a wider glenoid defect with good clinical outcomes, this technique had not been widely applied due to the limited bone width of the coracoid graft and high rate of coracoid osteotomy and screw fixation-related complications. The emerging suture button flexible fixation technique has been proven to achieve good clinical outcomes and is technically friendly. It can significantly reduce the requirements for large coracoid graft bone mass, and the Latarjet procedure's application scope is expanded. We introduce the suture button congruent arc Latarjet technique for treatment of massive GBL in this Technical Note.
