What causes Hill-Sachs lesions?
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.
What is a non engaging Hill-Sachs lesion?
Hill–Sachs lesions have been classified as “engaging” or “non-engaging”, with engaging lesions defined by the ability of the glenoid to sublux into the humeral head defect during abduction and external rotation.
What is engaging Hill-Sachs lesion?
Burkhart and De Beer [3] coined the term “engaging Hill-Sachs” to describe a lesion that predisposes to recurrent dislocation or to the symptoms of recurrent dislocation after Bankart repair [3].
How common is Hill-Sachs lesion?
The Hill-Sachs lesion is a bony defect of the humeral head that occurs in association with anterior instability of the glenohumeral joint. Hill-Sachs lesions are common, with an incidence approaching nearly 100% in the setting of recurrent anterior glenohumeral instability.
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.
Does a Hill-Sachs lesion heal?
Dr. Foreman: The Hill-Sachs lesion is a “divot” made in the bone and cartilage on the back of the ball (humerus) caused when it bangs against the edge of the socket (glenoid) when the shoulder dislocates. It will not heal, but usually doesn’t cause a problem unless it is very large.
How long does it take for Hill-Sachs to heal?
Following this procedure, the patient is immobilized in a sling for six weeks and is expected to attend four to six months of formal physical therapy to restore normal shoulder strength and function.
How do you fix Hill-Sachs deformity?
Remplissage (filling): This technique surgically adds tissue to the lesion. The procedure is usually done on Hill-Sachs lesions that are moderate in size and also have some amount of glenoid defect. Disimpaction: This involves a bone graft under the lesion to lift the humerus up to the pre-injury position.
Can Hill-Sachs lesion heal on its own?
Foreman: The Hill-Sachs lesion is a “divot” made in the bone and cartilage on the back of the ball (humerus) caused when it bangs against the edge of the socket (glenoid) when the shoulder dislocates. It will not heal, but usually doesn’t cause a problem unless it is very large.
Does a Hill-Sachs deformity require surgery?
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.
