Reduction of the glenohumeral joint is noted.
There is a fracture of the greater tuberosity. No bony Bankart lesion.
Case Discussion
Inferior shoulder dislocations are the least commonly encountered shoulder dislocation.
Due to the humeral head being stuck under the bony labrum, the arm is held in an abducted and external rotated position.
This condition is also called "luxatio erecta".
