Floating Inferior Glenohumeral Ligament: A Case Report.

A humeral avulsion of the glenohumeral ligament (HAGL lesion) is a relatively rare pathology seen in patients with traumatic anterior shoulder instability. A HAGL lesion combined with a Bankart lesion is called a floating inferior glenohumeral ligament (IGHL) and is rare. We report a case of floating IGHL that could not be diagnosed before surgery. A 32-year-old female presented with a fourth dislocation and underwent arthroscopic Bankart repair with the use of a flexible curved guide. During Bankart repair, the tip of the flexible drill was broken. We removed it under general anesthesia later. She had no recurrence three years after surgery and enjoyed skateboarding as a hobby.
