Radiography of right shoulder. Anteroposterior view showing glenohumeral
joint space widening (continuous arrows). The humerus presented with
internal rotation. The dashed arrow indicates fracture of the coracoid
process.

The analysis of the images showed coracoid process fracture, GHJ space widening, and internal humeral rotation (Figure 1).
MRI. Axial sections images acquired with intermediate weighting
demonstrates rotator cuff stumps interposition (arrows) between the
glenoid and the humerus, explaining the blockage and the joint space
widening.

The hypothesis of traumatic rotator cuff tear was raised on the basis of the plain radiography findings, and the patient was submitted to magnetic resonance imaging (MRI) whose images demonstrated the presence of a traumatic injury with interposition of the supraspinatus, infraspinatus and subscapularis tendons stumps in the GHJ (Figures 2 and 3).
MRI, coronal section, intermediate weighting. The arrows identify rotator
cuff stumps interposition between the glenoid and the humerus. The white
arrow indicates the supraspinatus tendon and the black arrow shows the
subscapularis tendon.

A: Intraoperative finding demonstrating uncovered humeral
head (continuous arrow) and retracted and interposed rotator cuff stumps
in the glenohumeral joint (dashed arrow). B: Intraoperative
finding demonstrating rotator cuff (continuous arrows), repaired by
surgical thread (dashed arrow) coursing up to the site of insertion of
the greater humeral tuberosity.
