What is a reverse Hill-Sachs lesion?
Reverse Hill-Sachs defect, also called a McLaughlin lesion, is defined as an impaction fracture of anteromedial aspect of the humeral head following posterior dislocation of the humerus. It is of surgical importance to identify this lesion and correct it to prevent avascular necrosis.
What causes reverse Hill-Sachs lesion?
Posterior dislocation of the humeral head may cause a posterior-directed shearing of the labrum or the bony glenoid rim [29, 30] but is primarily characterized by the osteochondral impression fracture of the ventromedial articular surface of the humeral head, the so-called reverse Hill-Sachs lesion [5, 31].
Does a Hill-Sachs lesion require surgery?
A Hill-Sachs defect that causes the ball to move abnormally within the socket is said to be “engaging,” and these engaging Hill-Sachs injuries usually require surgical treatment.
What is a Hill-Sachs lesion indicative of?
A Hill-Sachs defect is a posterolateral humeral head depression fracture, resulting from the impaction with the anterior glenoid rim, therefore indicative of an anterior glenohumeral dislocation. It is often associated with a Bankart lesion of the glenoid.
Does Hill-Sachs lesions heal?
For smaller sized Hills-Sachs lesions, in which less than 20% of the humeral head has been affected, physical therapy, or careful observation may be an effective option. For more severe cases and larger lesions, surgery is likely your best option for healing.
Do Hill-Sachs lesions heal?
Is Hill-Sachs lesion painful?
The most common sign of Hill-Sachs lesion is severe pain in the shoulder, especially during movement. Other symptoms you may notice include: Nausea, lightheadedness and weakness. Recurring shoulder dislocations.
Can Hill-Sachs lesion heal on its own?
What is considered a large Hill-Sachs lesion?
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.
Is there any scientific evidence for reverse Hill Sachs lesions?
Background: Little scientific evidence regarding reverse Hill-Sachs lesions (RHSLs) in posterior shoulder instability exists. Recently, standardized measurement methods of the size and localization were introduced, and the biomechanical effect of the extent and position of the defects on the risk of re-engagement was determined.
How to treat reverse Hill Sachs shoulder dislocation?
Subsequently, the affected shoulder should be immobilized in internal rotation or neutral position over a short period of time [ 6, 14 ]. Depending on the size, the reverse Hill-Sachs lesion is a risk factor for re-dislocation and therefore a surgical treatment is normally recommended [ 15 ].
How big is a reverse Hill Sachs compression fracture?
One patient with a defect greater than 40% of the articular surface had a total shoulder arthroplasty. The remaining twelve patients had a reverse Hill-Sachs compression fracture involving 25–40% of the articular surface of the humeral head following a traumatic posterior shoulder dislocation.
What are the different types of rhsl lesions?
Results: Three types of an RHSL were distinguished based on the pathogenesis and chronicity of the lesion: dislocation (D), locked dislocation (LD), and chronic locked dislocation (CLD).
