Answer: posterior shoulder dislocation (see axillary below)
1) both views look the same (internally rotated)
2) light bulb sign (humeral head looks like a light bulb)
3) loss of the normal half-moon overlap of the humeral head and the glenoid
4) irrregular posterior glenoid cortex c/w reverse “bony” Bankart
5) borderline “Rim sign” - widened glenohumeral distance (diagnostic is over 6mm, which this may be just under)
