Posterior shoulder dislocation: it's worth another look

A 40-year-old woman presented to the emergency department with a painful left shoulder following a fall from a mountain bike. A radiograph of the clavicle and shoulder was carried out. A diagnosis of fractured left clavicle was made, which was treated conservatively in a sling. On day 3, she was reviewed in the fracture clinic and was found to still be in pain with reduced movement of the shoulder joint. A repeat radiograph of the shoulder joint showed a posterior dislocation. This required a closed reduction under general anaesthesia.
