Diagnosing Shoulder Dislocations: Beyond the Obvious
Published: Oct 03, 2023
While a dislocated shoulder may seem obvious, proper diagnosis involves more than just looking at the joint. Accurate assessment is crucial for appropriate treatment and to identify any associated injuries.

Physical Examination
The first step in diagnosis is a thorough physical exam. Doctors look for visible deformity, swelling, and bruising. They'll gently test range of motion and check for nerve function in the arm and hand. The type of dislocation (anterior, posterior, or inferior) can often be determined by the arm's position.
Imaging Studies
X-rays are the primary imaging tool for confirming shoulder dislocations. They show the position of the bones and can reveal associated fractures. Multiple views are usually taken, including anteroposterior (AP) and axillary views. In some cases, CT scans or MRI may be needed for a more detailed look at soft tissues and complex injuries.
Ultrasound in Diagnosis
Bedside ultrasound is becoming increasingly popular for diagnosing shoulder dislocations. It's quick, doesn't use radiation, and can be used to confirm successful reduction. However, it may not detect all associated fractures, so X-rays are still often needed.
Frequently Asked Questions
Not always, but they're recommended in most cases.
It's useful but may miss fractures, so X-rays are often still needed.
It's often accurate but imaging confirms diagnosis and reveals complications.

Key Takeaways
Accurate diagnosis of shoulder dislocations requires a combination of clinical skills and appropriate imaging to ensure proper treatment.
