Inferior shoulder dislocation

Case contributed by Dr Derek Smith

Presentation

Collapse. Left arm held in abduction and external rotation.

Patient Data

Age: 80
Gender: Male
X-ray

Chest and left shoulder

The abnormality just visible on the chest x-ray, and better seen on the dedicated shoulder view, is a dislocated left shoulder.

The humeral head is inferiorly (technically antero-inferiorly) dislocated.

No fracture is currently evident.

X-ray

Post-reduction radiograph

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".
