DISLOCATIONS OF THE SHOULDER. 267 dislocation: viz., fracture of the acromion;—of the neck of the scapula;—and of the neck of the humerus. The first two may be known by thefacility with which the form of the joint is restored by raising the limb,and by the crepitus felt on doing so. In fracture of the cervix humeri,the limb is shortened, instead of being lengthened as it is in dislocation;—there is not so much vacuity under the acromion—and the rough angu-lar end of the shaft may be felt in the axilla
