Patient Data

Age: 35 years
Gender: Male
X-ray

Patient was unable to put his arm down on exam.

Frontal radiograph reveals the inferior dislocation of the humeral head (black arrow) from the glenoid fossa (white arrows). The humerus is parallel to the spine of the scapula, the common position in luxatio erecta.

Case Discussion

Luxatio erecta, an uncommon form of shoulder dislocation (0.5-1%),  is an inferior displacement of the humeral head with loss of articulation with the glenoid fossa caused by severe arm hyperabduction.  Essentially the arm is "locked" in abduction.  Often there is an associated greater tuberosity fracture.
