Background: Bankart lesions and Hill-Sachs lesions are commonly associated with anterior shoulder dislocations. The presence of Bankart lesion indicates the need for surgical repair. Magnetic resonance imaging MRI has been shown to be sensitive in detecting these two lesions. The aim of this study is to investigate the correlation between Bankart lesions and Hill-Sachs lesions on MRI for patients with traumatic anterior shoulder dislocations.

A linear bony fragment chipped fracture related to the inferior aspect of the glenoid process raises the possibility of a bony Bankart lesion, otherwise everything else seems to be in order. The CT confirms the X-ray finding of a chipped fracture of the inferior aspect of the glenoid process, however a wedge shaped defect can also be seen at the posterior aspect of the humeral head, that was not evident on the plain radiograph suggesting Hill-Sachs lesion with bony Bankart.
Another defect noted at the posterior aspect of the humeral head. Hill-Sachs fracture and Bankart lesion are common sequelae to recurrent anterior dislocation of the shoulder joint. Hill-Sachs lesion is a compression fracture of the posterolateral humeral head due to its compression against the anteroinferior part of the glenoid when the humerus is anteriorly dislocated. A Bankart lesion results from a detachment of the anterior inferior labrum from the underlying glenoid due to the same mechanism.
It may occur as an isolated injury to the labrum, or it can extend to the bony glenoid margin, where it is called a "bony Bankart". In most cases, both findings are associated together. Support Radiopaedia and see fewer ads.

Hill-Sachs Lesion: What Is It and How Is It Treated?
Hill-Sachs lesions are a posterolateral humeral head compression fracture, typically secondary to recurrent anterior shoulder dislocations , as the humeral head comes to rest against the anteroinferior part of the glenoid. It is often associated with a Bankart lesion of the glenoid. The concept of engaging. Bankart lesions are up to 11 times more common in patients with a Hill-Sachs lesion, with increasing incidence with increasing size 8. Hill-Sachs lesions may be difficult to appreciate on x-rays, frequently requiring CT or MRI for full characterization.
Correlation Between Bankart and Hill-Sachs Lesions in Anterior Shoulder Dislocation
A Hill—Sachs lesion , or Hill—Sachs fracture , is a cortical depression in the posterolateral head of the humerus. It results from forceful impaction of the humeral head against the anteroinferior glenoid rim when the shoulder is dislocated anteriorly. The lesion is associated with anterior shoulder dislocation. The result is a divot or flattening in the posterolateral aspect of the humeral head , usually opposite the coracoid process. The mechanism which leads to shoulder dislocation is usually traumatic but can vary, especially if there is history of previous dislocations. Sports, falls, seizures, assaults, throwing, reaching, pulling on the arm, or turning over in bed can all be causes of anterior dislocation.
