This is a scapular Y view which is a form of shoulder lateral radiograph. The humeral head should overly the intersection of the "Y" created by the scapular spine and the coracoid, which would indicate that it is centered on the glenoid. In this case, it is clearly anteriorly dislocated. The study by Visser et al showed the axillary nerve is most likely to be injured (42%)in anterior dislocations. Toolanen et al looked at anterior dislocations in patients over 40 years old, and found 6 of 55 cases had electromyographically verified axillary nerve or brachial plexus injury.
