Frontal

Question 1

Is the alignment of the glenohumeral joint normal?

Show Answer

No - there is inferior subluxation.

Question 2

What does this suggest?

Show Answer

In the presence of a fracture this suggests a joint effusion.

This AP xray of the left shoulder shows a transverse fracture of the surgical neck of the humerus with impaction of fragments. There is inferior displacement of the humeral head on the glenoid. This appearance (pseudosubluxation) is commonly seen in association with fracture and suggests joint effusion. There is a fat-fluid level consistent with a lipohaemarthrosis. This indicates the presence of intraarticular injury.
