Posterior shoulder dislocation

Discussion:

Posterior dislocations of the shoulder, are relatively uncommon, and usually, arise due to convulsive disorders. However, occasionally strength imbalance of the rotator cuff muscles may result in it without direct trauma, as demonstrated by the current case. The reverse Hill-Sachs lesion is a commonly associated fracture of posterior dislocation, and radiographic signs might be subtle. Careful scrutiny of the humeral head is therefore always mandated when posterior dislocation is found while reporting radiographs.
