S43.159
Posterior dislocation of unspecified acromioclavicular joint
Clinical Classification Guidelines
Medical Intelligence & Overview
The posterior dislocation of the acromioclavicular (AC) joint is a type of shoulder injury that occurs when the collarbone (clavicle) is forced out of its normal position behind the acromion, part of the shoulder blade. The AC joint is a key connection that links the clavicle to the acromion and helps facilitate shoulder movement. This injury can result from trauma, such as falls or direct impact, and can cause pain, swelling, and limited shoulder motion. Accurate diagnosis and appropriate management are essential for recovery and to prevent long-term shoulder problems.
Causes & Symptoms
Clinical Causes: Direct blow or trauma to the shoulder area Falls onto the shoulder or outstretched arm Motor vehicle accidents Sports injuries involving impact or falls Other traumatic incidents that exert force on the shoulder girdle
Key Symptoms: Sudden shoulder pain Swelling and tenderness around the joint Deformity or visible bump at the AC joint Limited or restricted shoulder movement A feeling of instability or shoulder 'slipping' Possible numbness or tingling if nerves are affected
Diagnostic & Treatment
Diagnosis Path: Doctors typically perform a physical examination to assess shoulder stability, deformity, and range of motion. Imaging tests are crucial for confirming the diagnosis and determining the extent of dislocation. These may include: - X-rays: To visualize the position of the clavicle relative to the acromion - MRI or CT scans: Sometimes used for detailed imaging, especially if associated injuries are suspected distinctly, the posterior dislocation will show the clavicle displaced behind the acromion on imaging studies.
Treatment Protocols: Management options depend on the severity of the dislocation. Common treatments include: - Rest and immobilization with a sling - Ice application to reduce swelling - Pain management with analgesics - Physical therapy to restore shoulder strength and mobility - Closed reduction: A procedure where a healthcare professional manually realigns the clavicle back into position, usually performed under anesthesia - Surgery: Required in cases of recurrent dislocation, associated fractures, or if the joint does not stabilize with conservative treatment Rehabilitation is essential for restoring function and preventing future dislocations. Follow-up evaluations are important to monitor healing and shoulder stability.
