A 38-year-old left-hand dominant lady fell on to her right arm when out drinking and attended the accident and emergency department the next day at 4 pm as the pain in the right shoulder had not settled down. These are the X-rays of her right shoulder (Figure 12.1a). What is your diagnosis?

Anterior dislocation of the right shoulder with an associated greater tuberosity (GT) fracture. Complete loss of joint congruence is demonstrated on the AP view, while the anterior displacement is best demonstrated on the axial view. There is no visible evidence of fracture through the anatomical neck, although this occurs in about 10% of cases. This pattern of injury is more in keeping with this patient’s age than surgical neck fracture, which is more typically seen in an older demographic.
