When the humerus is fractured, in most cases it only deviates outward. You should do what needs to be done to return the broken bone to its natural position in a way known to you, that is, feel it with your hand and straighten it sufficiently, then you bandage it with a bandage that goes up at least to the shoulder, and attach it there if the fracture is close to shoulder Then apply, as you already know, a bandage that goes down at least below the elbow, if the fracture is close to the elbow, and after that a third bandage that goes up from bottom to top, and hang your arm in a bent position so that it does not dangle while hanging, for this not good. It is best for the organ to rest on the chest, bent at the elbow, and not move, especially if it is broken near the elbow. If the fracture is not yet swollen, moisten the bandage with water and vinegar or water alone and make it from linen cloth four fingers wide, no less, and if pus has already reached the organ and it is swollen, then make a bandage of six and moisten it with oil. If this is possible and nothing prevents it, then under no circumstances unravel it until the seventh day and later, until the tenth, and then unravel it and apply splints. And if caution calls on you to do otherwise, then loosen the bandage on the third day, which is exactly what Hippocrates is inclined to do, for this prevents many damages, although it harms the fusion. As for the method of applying splints, then what we have explained when talking about them should be enough for you. Do not leave the patient without dressing for at least forty days.
If for a good recovery you need to strongly stretch the organ, and you cannot do this and there is no benefit from the assistance of the one who helps you, then sit the patient on a bench raised above the ground, so that he stands rather than sits, and let him lean under with the mouse on a stair step or something similar, as you learned from the paragraphs about dislocation, and this place was first leveled and made soft and smooth. Then let some heavy thing be hung from his elbow, which will pull it down, and when the bone is stretched to the desired limit, it is leveled.
If it is enough for you to make strong bandages below and above the fracture site and lay the patient on his back so that strong people pull the places you have bandaged up and down, then this is enough if the fracture occurs in the middle of the humerus, then you apply the bandage at the same distance from the ends of the joint, and if it is closer to some end, then you make the dressing very close to one end and far from the other. When there is only a crack, treat it as you would treat cracks, and tie the bandage tightly around it.
