A 30-year-old female fell while rollerblading and now has pain and deformity in her left shoulder. Her arm is held in external rotation and she is unable to move it. What is the likely diagnosis and what would be the next step in management?
This presentation is suggestive of an anterior shoulder dislocation, which is the most common type of shoulder dislocation. The patient should be offered pain relief, and an X-ray should be obtained to confirm the diagnosis and rule out associated fractures. The shoulder should then be reduced using an appropriate technique, with care taken to avoid nerve and vascular damage.
