Its existence has been Cooper and South have stated that cases so described are in realityfractures of the upper end of the humerus. There is, according to South,no specimen in any of the London museums illustrating fracture of the neckof the scapula (Erichsen). Walsham describes one case of this variety offracture which is in Guys Hospital museum, and Rose and Carless figure aninstance of this variety. It is usually due to direct violence; a portion of the.
