In this position, the humeral head is drawn cranially and posteriorly against the glenoid fossa by contraction of the shoulder muscles.7 During the seizure, the anatomical neck of the humerus is pulled towards the rim of the glenoid fossa, becomes impacted and can eventually be fractured.5 Apparently the same mechanism occured in our patient during the seizure.
