A Bankart lesion is an injury to the anteroinferior glenoid labrum that typically occurs following an anterior shoulder dislocation.
A Bankart lesion is an injury to the anteroinferior glenoid labrum that typically occurs following an anterior shoulder dislocation. Patients with this lesion are at increased risk for recurrent shoulder dislocations and ongoing instability. Diagnosis is based on clinical history, physical examination, and confirmation with MRI imaging.
Treatment may be nonsurgical or surgical depending on the severity and size of the lesion, with arthroscopic repair being the most commonly performed approach. A Bankart lesion occurs as a direct result of an anterior dislocation of the humeral head, during which the humerus is forcefully compressed against the glenoid labrum. This leads to detachment of the anteroinferior labrum from the underlying glenoid, often accompanied by an impaction fracture of the anterior-inferior glenoid rim.
The labral tear may also extend superiorly or posteriorly, with the lesion most commonly located around the 3:30 position on the glenoid. A Bankart lesion involves injury to the anteroinferior labrum along with associated glenohumeral capsule and ligament damage. A bony Bankart refers to a fracture of the adjacent anteroinferior glenoid, often occurring alongside anterior shoulder dislocation.
Soft tissue Bankart lesions are more common than bony variants, appearing in up to 22% of first-time anterior shoulder dislocations. The prevalence of bony Bankart lesions varies widely, ranging from approximately 7.9% to 50% in cases of traumatic shoulder instability.https://www.youtube.com/watch?v=5ehcFn4_gN4https://www.youtube.com/watch?v=6dx7tLPdfuQIn evaluating a potential Bankart lesion, patients are typically able to describe a history of shoulder dislocation, including details about the mechanism, direction of force, perception of instability, prior dislocations, need for manual reduction, and any previous surgeries. Symptoms may include recurrent dislocations, generalized shoulder discomfort, and sensations of locking, catching, or popping.
The physical exam should include visual inspection, palpation, assessment of passive and active range of motion, strength testing, and neurovascular evaluation. Bony bankart lesion from 3-6 o clock positionRadiographic evaluation of a Bankart lesion typically begins with standard shoulder X-rays, which are often normal. The Bernageau view provides improved visualization of the anterior glenoid rim and can help identify a bony Bankart lesion, seen as a cortical defect at the anteroinferior glenoid, or an associated Hill-Sachs deformity on the posterior humeral head.
If you are experiencing symptoms that may be related to bankart lesions, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
