Thus : " If in another- subject the outer end of the clavicle be forced backwards, so that it rests upon the first rib outside its tubercle, being separated from it by the scalenus medius, and a heavy blow be struck horizontally backwards on its padded outer extremity, in some rare cases the inner end of the clavicle is dislocated forwards, but in the large majority of cases the first rib is fractured at the point of impact. The facility with which this fracture of the first rib is produced is remarkable, and if one compares the relative thickness and strength of the first rib and clavicle and the mechanical advantage of the action of the clavicle upon the first rib, one would not be surprised to find this fracture occur not uncommonly during lifetime."
