Presentation
Fall on outstretched hand two days ago, felt pop in left shoulder. Previous surgery for dislocation. Diffuse bony tenderness and reduced range of movement ?fracture ?dislocation
Patient Data



On the AP projection, there is irregularity at the inferior cortex of the glenoid suspicious for fracture.
On the axial projection, there is a triangular ossific density seen anteriorly to the greater tuberosity, suspicious of further fracture at this site.
The glenohumeral and acromioclavicular joints are congruent.







There is a displaced fracture of the anteroinferior left glenoid.
There is slightly displaced comminuted fracture involving the left greater tuberosity.
Mild degenerative changes are noted in the acromioclavicular and glenohumeral joints.
Within the limitation of CT, the rotator cuff muscles appear intact.
Case Discussion
Glenoid fractures are relatively uncommon, and are often associated with dislocation.
Ideberg classification is often employed by orthopaedics.
