Bankart lesion
A Bankart lesion is an injury of the anterior (inferior) glenoid labrum of the shoulder due to anterior shoulder dislocation.[1] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it. It is an indication for surgery and often accompanied by a Hill-Sachs lesion, damage to the posterior humeral head.[2]
The Bankart lesion is named after English orthopedic surgeon Arthur Sydney Blundell Bankart (1879 – 1951) [3]
A bony bankart is a Bankart lesion that includes a fracture in of the anterior-inferior glenoid cavity of the scapula bone.[4]
Diagnosis
The diagnosis is usually initially made by a combination of physical exam and MRI of the shoulder, which can be done with or without the injection of intraarticular contrast. The presence of contrast allows for better evaluation of the glenoid labrum.[5]
Treatment
Arthroscopic repair of Bankart injuries have limited success rates, with studies showing that nearly one-third of patients require re-intervention for continued shoulder instability following repair.[6] Options for repair include an arthroscopic technique or a more invasive open Latarjet procedure,[7] with the open technique tending to have a lower incidence of recurrent dislocation, but also a reduced range of motion following surgery.[8]
