Arthroscopic Treatment of Bony Bankart Lesions
2014
Glenoid anterior rim fractures, accompanied by acute glenohumeral dislocation and subluxation with tremendous amount of external force, usually result in persistent instability of the glenohumeral joint. According to a three-dimensionally reconstructed computed tomography (3D-CT) study, the prevalence of anterior glenoid bony lesion has been reported as high as 90 % in shoulders with chronic recurrent traumatic anterior instability and an associated bony fragment is present in about half of shoulders with anterior glenoid bony lesion. Further, bone loss in shoulders associated with a bony fragment is relatively significant compared to that in shoulders with attritional glenoid without bony fragment.
