Despite an increased awareness of the condition, the diagnosis, classification, and treatment of recurrent posterior shoulder instability remain challenging. No clear relationship has been established between glenohumeral morphologic characteristics and the risk for posterior shoulder instability or with outcomes after treatment. ⋯ Although higher glenoid retroversion was noted in this patient population as compared with previous studies in normal populations, there were no significant differences in outcomes after treatment among subjects with regard to glenoid version. However, increased glenoid width did predict better outcomes after posterior capsulolabral repair.
