![[ 23 ] from the patient (which he fhould always do), the elevation will be made in an oblique direction, and adapted to the inclined plane of the lcapula. As for the cartilaginous lip, which increafes the depth of the articular cavity, its elafticity will prevent its proving any great obftacle to the return of the head. The fracture of the neck of the fcapula, when made in attempting reduction, by hanging the arm of a patient over a door or ladder, or the top of a chair, is, I imagine, always produced independent of the p re flu re of the head of the humerus, for in all fuch attempts the fcapula is brought much more forwards than it lies naturally, and the inferior angle is fomewhat elevated—fo that when the arm is drawn as far as poflible over the edge of the door, or the round of the ladder, and firmly retained in that fltuation, the whole weight of the body, when the fupport of the patient’s feet is taken away, muft be thrown with a jerk upon the cervix of the fcapula. Betides, in moft of thefe obflinate cafes, the head of the humerus will have been thrown forwards under the pecftoral mufcle, and be out of way of doing immediate mifehief by ftriking againft the neck of the fcapula. If the extenflon be made in a proper direction, fo as to bring the head of the bone to a level with the edge of the articular cavity, I believe that, in general, “ the mufcles will “ do the reft for the furgeon*;” but if the extenflon do not bring it to that level, though by lefs than the tenth of an inch, the mufcles will not then do their work in the way the furgeon wiflies them ; lor if they adl at all, it will be in retracting the bone towards its former unnatural fltuation. Whereas if, belidc the extenflon, the bone be aflilted by a leveraging in a proper direction, it will be eaflly lifted over a fmall afeent, * Pott’s Works. and](https://iiif.wellcomecollection.org/image/b21913183_0042.jp2/full/800%2C/0/default.jpg)
