Which view of radiograph is good to identify the Hill-Sachs lesion?
Which view of radiograph is good to identify the Hill-Sachs lesion?
In our series, the 45″ craniocaudal view had a high diagnostic yield in demonstrating both the Hill-Sachs defect and the Bankart lesion.
What is a Hill-Sachs defect?
A Hill-Sachs lesion is a fracture in the long bone in the upper arm (humerus) that connects to the body at the shoulder. You doctor might have discovered this condition if you’ve experienced a dislocated shoulder. In this case, the arm bone slips out of the socket and is compressed against the socket’s rim.
What is a Hill-Sachs lesion indicative of?
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.
How is Hill-Sachs defect measured?
Di Giacomo’s method consists of four evaluation steps: the first measures the diameter (D) of the inferior glenoid using the perfect circle method, the second measures the amount of glenoid anterior bone loss (d), then the third calculates the width of the glenoid track (GT) = 0.83D–d, and the last measures the width …
How do you repair 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.
What causes glenoid bone loss?
Glenoid bone loss is suggested when a patient recalls a high-energy injury mechanism, especially if the arm was abducted (70° or more) at that time. Patients with osseous defects usually complain of instability within the midranges of motion (20° to 60° of abduction) or recall a progression of instability.
What is Hill Sachs defect?
The Hill-Sachs defect occurs when there is an injury to the bone and cartilage of the humeral head. As the humeral head dislocates from the socket of the shoulder joint, the round humeral head strikes the edge of the socket with force. This creates a divot in the humeral head called a compression fracture.
What is reverse Hill Sachs lesion?
Reverse Hill-Sachs lesion, also called a McLaughlin lesion, is defined as an impaction fracture of anteromedial aspect of the humeral head following posterior dislocation of the humerus.
What is small Hill Sachs lesion?
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.
