AB History 
    An abnormality of the distal left clavicle was identified on a routine chest film of a professional hockey player, and this was confirmed on a shoulder roentgenogram (Fig 1). He denied pain or weakness in the left arm.Diagnosis 
    Traumatic osteolysis of the distal end of the clavicle.Comment 
    The shoulder films (Fig 1 and 2) show resorption of the distal clavicle resulting in an increased distance between the clavicle and acromion. Bony fragments are present adjacent to the tapered distal clavicle (large arrow). The insertion of the acromioclavicular ligament is calcified from past trauma (small arrow).Traumatic osteolysis of the distal clavicle follows severe injury to the shoulder. It is seen in contact sports (rugby,1 football,2 hockey,3 and judo4) and in certain other occupations, but most frequently follows a fall2,5 or motor vehicle accident.2,6 The injury is reported infrequently; it is first
