Case report 752: Normal variant of the acromion simulating grade I acromioclavicular separation.
This case illustrates a developmental variant of the acromion resulting in apparent widening of the acromioclavicular joint space rather than discontinuity of the inferior cortices of the acromioclavicular joint. Had an axillary view not been obtained, an erroneous radiographic diagnosis of grade I acromioclavicular separation might have been suggested.
