The Posterior Shoulder Dislocation Reduction Guide
The Posterior Shoulder Dislocation Reduction Guide A posterior shoulder dislocation occurs when the head of the humerus is displaced backward out of the glenoid cavity. Although less common than anterior dislocations, posterior dislocations present unique challenges in diagnosis and management. Prompt and proper reduction is critical to restore shoulder stability and prevent long-term complications such as avascular necrosis or chronic instability.
Patients with posterior shoulder dislocation often report pain, limited shoulder movement, and a sense of shoulder weakness. They may also present with the arm held in a slightly adducted and internally rotated position. Due to its subtle presentation, posterior dislocation can be easily overlooked on initial clinical assessment and standard radiographs, which makes understanding reduction techniques essential for healthcare providers.
The reduction process begins with a thorough assessment, including radiographic confirmation. Standard anterior-posterior (AP) views may sometimes miss posterior dislocation; hence, additional imaging like axillary views or scapular Y-views are recommended. Once diagnosed, the clinician should prepare the patient by explaining the procedure, ensuring adequate sedation or anesthesia, and positioning the patient appropriately to facilitate reduction.

The Posterior Shoulder Dislocation Reduction Guide One of the most common techniques for posterior shoulder dislocation reduction is the * Milch method*. It involves abducting the arm to about 90 degrees, gently applying longitudinal traction, and gradually externally rotating the arm to guide the humeral head back into the glenoid cavity. Gentle, controlled movements are essential to reduce pain and avoid iatrogenic injury.
Another widely used technique is the *Hennepin method*, which involves flexing the patient’s shoulder to 90 degrees, applying anteriorly directed pressure on the humeral head, and then gradually extending and externally rotating the arm. This technique harnesses the natural movement to facilitate reduction with minimal force.
The *Kocher maneuver* is also employed but is less favored in posterior dislocations due to its more complex steps tailored mainly for anterior dislocations. However, when used, it involves gentle external rotation, adduction, and internal rotation, emphasizing cautious manipulation. The Posterior Shoulder Dislocation Reduction Guide
The Posterior Shoulder Dislocation Reduction Guide Regardless of the method used, the clinician must monitor the patient closely for signs of neurovascular compromise during reduction. After successful reduction, repeat radiographs are necessary to confirm proper alignment. The shoulder should then be immobilized in a position that promotes stability—often in a neutral or slight external rotation position—followed by a structured rehabilitation program to restore range of motion and strengthen shoulder muscles.
In cases where closed reduction fails or if there are associated fractures or soft tissue injuries, surgical intervention may be indicated. Post-reduction, the focus is on preventing recurrence and restoring optimal function through physiotherapy and patient education about activity modifications.

Proper training and familiarity with these maneuvers can significantly improve patient outcomes and reduce the risk of complications.
