A Hill-Sachs lesion is a typical impression fracture in the long bone of the upper arm humerus head compression injury to the posterolateral aspect of the humeral head created by the hits against the anterior edge of the glenoid labrum rim that connects to the body at the shoulder joint and caused by the anterior compression fracture of the humeral head in posterior shoulder dislocation. Your doctor might have discovered this condition if you’ve experienced a dislocated shoulder. For this reason, the arm bone slips out from the socket and is compressed against the socket’s rim in shoulder joint.
In Hill-Sachs lesion, the arm is abducted and externally rotated that falls onto an outstretched arm or with the arm overreached in the elevated and externally rotated position.[rx] In the externally rotated position, the posterosuperior aspect of the humeral head abuts and drives through the anteroinferior aspect of the glenoid rim displace. This can damage the humeral head, glenoid labrum, and rims. An associated humeral head compression fracture and glenoid labrum is a fibrocartilaginous structure that rings the circumference of the glenoid fossa.
