The glenoid labrum, labeled glenoid ligament, is damaged in a Bankart lesion. Lateral view demonstrating the articular surface of the right scapula is shown.
Symptoms Shoulder instability and widespread shoulder discomfort, and catching, locking, or popping feelings in shoulders. [1]
Risk factors Anterior shoulder dislocation and/or repeated anterior shoulder subluxations. [2]
Diagnostic method X-ray and MRI.
Differential diagnosis Anterior labroligamentous periosteal sleeve avulsion, Rotator Cuff Tears, SLAP Lesion, Impingement, Perthes lesion, Glenolabral articular disruption, Humeral avulsion of the glenohumeral ligament. [2]

A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [3] It is an injury of the anterior (inferior) glenoid labrum of the shoulder. [4] 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. [5]

Contents

A bony Bankart is a Bankart lesion that includes a fracture of the anterior-inferior glenoid cavity of the scapula. [6]

The Bankart lesion is named after English orthopedic surgeon Arthur Sydney Blundell Bankart (1879–1951). [7]

Signs and symptoms

Bankart lesions are characterized by recurrent shoulder instability and widespread shoulder discomfort. Some individuals may experience catching, locking, or popping feelings in their shoulders. The majority of Bankart lesion patients have primary or recurrent anterior shoulder dislocation. [1]

Diagnosis

The diagnosis is usually initially made by a combination of physical exam and medical imaging, where the latter may be projectional radiography (in cases of bony Bankart) and/or MRI of the shoulder. The presence of intra-articular contrast allows for better evaluation of the glenoid labrum. [8] Type V SLAP tears extend into the Bankart defect. [9]

Treatment

Arthroscopic repair of Bankart injuries have good success rates. However, a study has found that nearly one-third of young adult patients require further surgery for continued instability after the initial procedure, with higher re-operation rates in those less than 20 years of age. [10] Options for repair include an arthroscopic technique or a more invasive open Latarjet procedure, [11] with the open technique tending to have a lower incidence of recurrent dislocation, but also a reduced range of motion following surgery. [12]
