What is a hill Sach lesion?
The Hill-Sachs lesion is an osseous defect of the humeral head that is typically associated with anterior shoulder instability. The incidence of these lesions in the setting of glenohumeral instability is relatively high and approaches 100% in persons with recurrent anterior shoulder instability.
Which of the following is the best projection for assessing Hill-Sachs lesions?
The West Point axillary view is very useful in evaluating glenoid bone loss, while the Stryker Notch view is specific in evaluating for Hill-Sachs defects [13]. The Stryker Notch view is particularly useful because the internal rotation of the humeral head brings the posterolateral bone defect into view.
How does Hill-Sachs lesion occur?
A Hill-Sachs lesion only occurs when there is forward dislocation of the shoulder. View a detailed BodyMap of the shoulder. A dislocation injury can happen in sports, in a fall, or in reaching or pulling with your arm extended. Shoulders are the most commonly dislocated major joint .
How do you fix a Hill-Sachs lesion?
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.
Is Hill-Sachs lesion serious?
The outlook for recovery from a dislocated shoulder and a Hill-Sachs lesion is generally good. But a recurrence of a dislocation is common, especially in younger people.
What is a Hill Sachs defect?
Hill-Sachs defect. an irregularity seen in the head of the humerus following anterior dislocation of the shoulder; caused by impaction of posterolateral portion of the head of the humerus against the anterior edge of the glenoid. Synonym(s): Hill-Sachs lesion.
What is Hill Sachs injury?
A Hill-Sachs lesion, or Hill-Sachs impaction fracture, is an injury to the back portion of the rounded top of your upper arm bone (humerus). This injury occurs when you dislocate your shoulder. It’s named for the two American radiologists who first described the injury in 1940: Harold Hill and Maurice Sachs .
What is a 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. 1 When driven from the glenohumeral cavity during dislocation, the relatively soft head of the humerus hits against the anterior edge of the glenoid .
