After three weeks the forearm may be released, but the cap and axillary pad must be continued to be worn two or three weeks longer while the arm is well drawn to the side, and the wrist carried in a sling. =Fracture of the Great Tuberosity= of the humerus is difficult to treat, on account of the tuberosity being carried backwards by the muscles and the humerus being rotated forwards. Hence the parts must be braced together with a firm cap of gutta-percha moulded on to the shoulder while soft, and while the fractured parts are held in apposition, which may be done by the fingers, or by putting on a wet roller firmly over the shoulder as a spica before the splint is set. When the splint is hard the bandage may be taken off, and the splint removed and finished ready for application. In doing this, the steps are the same as for fracture of the surgical neck of the humerus, and the necessity for fixing the arm well to the side of the body as great as in that fracture. =Fracture of the Acromion= is treated very much like fracture of the clavicle, that is, the arm is well raised by a sling under the elbow, and then fastened to the side. It is not necessary to fill the axilla with a pad, as in fracture of the clavicle, for in this case the shoulder is not drawn inwards. =Fracture of the Clavicle.= _Apparatus._—1. Axillary pad. 2. Roller, 3 inches wide. 3. Sling. 4. Wool. Fractures of the clavicle nearly always leave some deformity after union; this is best avoided by keeping the patient on his back on a flat couch with the head alone supported by a cushion, and the arm fixed to the side until union has taken place. As most persons will not submit to a fortnight or three weeks’ confinement in bed for this accident, the fragments must be kept in position as nearly as possible by apparatus while the patient goes about. The displacement of the outer fragment is _inwards_, _downwards_, and _forwards_. Many varieties of apparatus are employed to prevent this displacement during union; the following mode is perhaps as effectual as any other in accomplishing this object. Step 1. Fix in the arm-pit a firm wedge-shaped pad of bedtick filled with chaff; 5 inches broad, 6 inches long, and 1½ or 2 inches thick at the thick end, or just enough to fill the axilla and throw out the humerus without compressing the axillary vein, hence the thickness varies with the hollowness of the axilla (see fig. 38). A band and buckle are stitched to the thick end, which is uppermost. When in use, this band is passed over the opposite shoulder and keeps the pad in place. A little wool should be put under the band, where it crosses the root of the neck, to prevent chafing.
