Glenoid index: a new risk factor for recurrence of glenohumeral instability after arthroscopic Bankart repair.

Background: The glenoid index (GI) (glenoid height to width ratio) has been shown to be a risk factor for instability in young healthy athletes. Nevertheless, whether the altered GI is a risk factor for recurrence after a Bankart repair remains unknown.

Methods: Between 2014 and 2018, 148 patients ≥ 18 years old with anterior glenohumeral instability underwent a primary arthroscopic Bankart repair in our institution.

Coracoclavicular Double-Button Fixation of Displaced Lateral Clavicular Fracture in a Patient without Coracoid Process.

Background: Displaced distal clavicular fractures are generally operated on because of the high nonunion rate after nonoperative treatment. Several surgical techniques have been developed to reduce the nonunion rate and improve functional outcomes. One of them is closed reduction and minimally invasive coracoclavicular double-button fixation, which requires the integrity of the coracoid process to be performed.
