What is the treatment of choice for a posterior shoulder dislocation?

The treatment of choice for a posterior shoulder dislocation is closed reduction. This method is often preferred in most cases of shoulder dislocations due to its less invasive nature and the ability to effectively restore the normal anatomy of the shoulder joint without the need for surgical intervention.

In posterior dislocations, the humeral head is positioned behind the glenoid, and closed reduction involves manipulation of the joint to reposition the humerus back into the glenoid cavity. This can usually be accomplished under sedation or anesthesia to minimize discomfort for the patient and ensure proper muscle relaxation during the procedure.

Closed reduction is advantageous because it typically allows for quicker recovery and rehabilitation compared to open surgical options, which may involve more significant operative risks and longer recovery times. Patients generally continue with physical therapy after closed reduction to regain strength and range of motion in the shoulder.

In summary, closed reduction is deemed the ideal first-line treatment for uncomplicated posterior shoulder dislocations due to its efficacy, safety, and less invasive nature compared to other treatment modalities such as open reduction or corticosteroid injections.
