Reverse Hill-Sachs lesion

A Reverse Hill-Sachs lesion is a compression fracture of the anterior aspect of the humeral head.

This condition typically occurs in association with a posterior shoulder dislocation, which is less common than anterior dislocations.

During a posterior dislocation, the humeral head is forced backwards, causing an impaction fracture as it collides with the posterior rim of the glenoid cavity.

The lesion itself is characterized by a dent or divot in the humeral head, which may compromise joint stability and function.

This can lead to chronic shoulder instability and recurrent dislocations if not properly addressed.

Symptoms may include pain, limited range of motion, and a feeling of looseness in the shoulder joint.

Diagnosis is usually confirmed through imaging studies like X-rays, MRI, or CT scans, which can visualize the extent of the bony defect and any associated injuries to the surrounding soft tissues.

Treatment options depend on the severity of the lesion and can range from physical therapy to surgical intervention to restore joint congruity and function.
