Posterior glenohumeral joint instability makes up approximately 2% to 10% of all shoulder instability reports in the literature and pathologic ﬁndings in patients, which often involve a spectrum of pathology rather than a single pathoanatomic ﬁnding. A combined posterior Bankart lesion and posterior humeral avulsion of the glenohumeral ligament has been deﬁned as the ﬂoating posterior inferior glenohumeral ligament. This combination of pathology may result in severe posterior-inferior instability and the need to address both lesions during attempted surgical repair has therefore been stressed.
In this study, “Repair of Floating Posterior Inferior Glenohumeral Ligament Lesions: Surgical Technique”, suggested techniques for repairing the various subtypes of ﬂoating posterior inferior glenohumeral ligament lesions is discussed. Repair of both the humeral and glenoid-sided injuries are addressed.
