What is Hill-Sachs Bankart lesion?
What is Hill-Sachs Bankart lesion?
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.
Is Hill-Sachs lesion serious?
Bony defects covering under 25% of the humeral head surface are typically insignificant in an isolated situation. However, depending on concomitant glenoid bone loss and the degree of engagement with the glenoid, even a small Hill-Sachs lesion can become clinically significant [5].
How are Hill-Sachs lesions diagnosed?
A doctor can diagnose a dislocated shoulder during a physical examination, but determining whether you have a Hill-Sachs lesion or other damage will require further testing. The doctor will ask how your shoulder injury occurred, whether it’s happened before, and what your symptoms are.
Why is it called a Bankart lesion?
The Bankart lesion is named after English orthopedic surgeon Arthur Sydney Blundell Bankart (1879–1951). A bony Bankart is a Bankart lesion that includes a fracture of the anterior-inferior glenoid cavity of the scapula bone.
What causes Hill-Sachs lesion?
This lesion is caused by an anterior shoulder dislocation which causes a humeral head impression fracture. The posterolateral aspect of the humeral head impacts on the anterior glenoid in the dislocated position, causing instability at the glenohumeral joint.
How is a Hill-Sachs lesion repair?
Large or engaging Hill-Sachs lesions are addressed by either reconstructing (rebuilding) any lost bone on the glenoid side or performing a “Remplissage” procedure which repairs the posterior capsule and rotator cuff tendon to the Hill-Sachs bone defect.
What causes Hill-Sachs deformity?
A Hill-Sachs deformity is a compression injury to the posterolateral aspect of the humeral head created by the glenoid rim during dislocation. When driven from the glenohumeral cavity during dislocation, the relatively soft head of the humerus hits against the anterior edge of the glenoid.
What is Bankart shoulder?
A Bankart injury occurs when an initial shoulder dislocation damages the anterior glenoid labrum of the shoulder joint. The labrum is a thick band of cartilage that lines the glenoid (socket). This attaches to the bone and helps keep the ball of the humerus in place.
What causes a Bankart lesion?
A Bankart lesion is a lesion of the anterior part of the glenoid labrum of the shoulder. This injury is caused by repeated anterior shoulder subluxations. The dislocation of the shoulder joint (anterior) can damage the connective tissue ring around the glenoid labrum.
