Is the alignment of the glenohumeral joint normal?
No - there is inferior subluxation.
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.
