De Medicina

11 So much for the discussion of fractured bones. Turning to dislocations, these are of two kinds: for at times bones which are conjoined gape asunder, as when the shoulder-bone recedes from the clavicle, and, in the forearm, the radius from the ulna, or in the leg the tibia from the fibula; sometimes after a jump the heel-bone from the ankle, though this is rare; at times joints slip out of position. I will speak of the former first.

Now when anything of this sort happens, there is a depression at once on the spot, and when the finger is put into this a gap is felt; after this severe inflammation arises, particularly at the ankle; indeed this is often a cause of fevers also and gangrene and spasms of the sinews or rigors, which bend back the head to the shoulder-blade. To avoid these things the same is to be done as was laid down for bone injuries in general, so that pain and swelling may be thereby relieved. For bones so separated never again unite, and even if the appearance of the limb is somewhat impaired its usefulness is not.

Since all joints, including the jawbone and vertebrae, are held in place by strong sinews, they are displaced either by force or after some accident which has ruptured or weakened the sinews, and this occurs more readily in boys and youths, than in the more robust. And these joints slip out

forwards, backwards, inwards, outwards, some in all directions, some in certain only. And there are some signs which are common to all, some special to each; there is always a swelling in the part into which the bone has ruptured, and a hollow whence the bone has receded. These signs are found in all, but others only in some cases; these I will describe when speaking of each separately. But while it is possible for all joints to slip out, yet not all can be replaced. For the head is never forced back into position, nor is a spinal vertebra, nor a jawbone which has been dislocated forwards on both sides, and has become inflamed before it has been replaced. Again, any joints which have slipped owing to a lesion of their sinews, even when forced back into position slip out again. Also when joints have been dislocated in childhood, and have not been replaced, there is less growth than elsewhere. The flesh of all which are out of place wastes, and in the near more than in the distant part of the limb; for instance, if the upper arm-bone is not in its place, the wasting is more here than in the forearm, more in the forearm than in the hand. Again, according to the site and character of the accidents, more or less use of the limb is retained; and the more use is retained, the less does it waste. Now every dislocation ought to be replaced before there is inflammation; but if this has set in already, the limb is not to be disturbed until after it subsides; only when it has ended should replacement be attempted in the limbs which allow of it. But for this much depends upon the general constitution of the patient and his sinews. For if his body is slender, and humid, if sinews are weak, the bone is readily replaced; but just as the bones slips out more easily in the first instance, so the replacement is less secure. With an opposite type of constitution the replacement is more lasting but there is more difficulty in restoring that which has been put out of position. The inflammation should be relieved by applying greasy wool saturated with vinegar: there should be abstinence from food, in the case of the stronger joints, for three days, some he said for five; warm water is drunk, enough to relieve thirst; this regimen must be followed more strictly after dislocation of bones which are held in place by strong and large muscles; far more strictly indeed if fever supervenes; then after the fifth day there should be hot-water fomentation; when the wool is removed, a cerate must be applied made with cyprus oil with the addition of soda, until all inflammation has ended. Then the limb is to be rubbed, good food given and wine in moderation; and now also the natural use of the limb is to be encouraged; because though movement when it gives pain is harmful, it is otherwise most beneficial to the body. After these generalities, I will now speak of particular cases.

12 The lower jaw is displaced forwards, sometimes on one side, sometimes on both. If on one side, it inclines with the chin to the opposite side, the teeth do not correspond with their fellows, but the canine are under the incisors. But if on both sides, the whole chin is moved forwards, and the lower teeth stick out beyond the upper ones; and the muscles above appear tense. As soon as possible the patient is to be seated on a stool, with an assistant behind holding his head, or with his

back against a wall and a hard leather cushion between the wall and the back of his head, against which his head is firmly pushed by the assistant, to keep it from moving. Then the surgeon's thumbs, which have been wrapped round with strips of linen or bandages so that they may not slip, are inserted into the mouth whilst the fingers are applied outside. When the jaw has been grasped firmly, if it has slipped forwards to one side, the chin is to be pressed down towards the throat with a jerk. Then simultaneously the head is firmly held, and the chin being raised the jaw is forced back to its place, and the mouth is closed so that all this is done almost with one movement. If it has been dislocated on both sides all the same movements are to be done except that the jaw is forced straight backwards. When the bone is in its place, if the accident has been attended with pain in the eyes and neck, blood is to be let from the arm. For all patients with dislocated bones, a more liquid diet is proper at first, but especially in this case, since even talking, as it causes constant movement of the mouth by means of the sinews, is harmful.

13 As I stated in the first part, the head is held by two processes, inserted into two cups in the highest vertebra. These processes sometimes slip out backwards; with the result that the sinews under the occiput are stretched, and the chin fixed to the chest; the man cannot drink or speak, and sometimes has involuntary emission of semen; upon these symptoms death very quickly supervenes. Now I

 thought this condition should be described, not that there is any treatment for it, but that it may be recognized by these indications, and that those who have lost someone in this way may not deem the medical man to have been at fault.

14 The same fate awaits those whose spinal vertebrae have been dislocated; for this cannot happen without rupture of the marrow in the middle of them, and of the two little membranes which pass oust between the two processes at the side, and of the sinews which hold them together. But the vertebrae may slip pout both backwards and forwards, above the diaphragm or below it. The direction of the displacement is indicated either by a swelling or by a hollow at the back. If it happens above the diaphragm, there is paralysis of the arms, and vomiting or spasm follow, breathing is difficult, pain is severe, and hearing blunted. If below the diaphragm, the lower limbs are paralysed, the urine is suppressed, or sometimes is passed involuntarily. From such accidents the man dies more slowly than when the head is displaced, yet within three days. As for what Hippocrates said, that when a vertebra has been displaced backwards, the man is to be laid out on his face, and stretched out, while an assistant presses his heel upon the displaced bone and pushes it inwards, that procedure is only to be adopted when the bone has slipped out a little, not if there is a total displacement. For occasionally weakness of the sinews causes a vertebra, although not displaced, to project a little, either backwards or forwards. This is not a fatal accident, but we cannot press upon a vertebra from within; it cannot even be touched; and if it is pressed upon from outside,

it generally slips back again, unless, as very rarely happens, the strength of the sinews is renewed.

15 Passing to the humerus, it is sometimes put out into the armpit, sometimes forwards. If it is dislocated into the armpit, the elbow stands out from the side; again, this elbow, together with the upper arm, cannot be raised to the level of the ear on the same side, and that forearm is longer than the other. But if forwards, the upper forearm can be stretched out, but not to its full extent; and it is more difficult to stretch out the elbow forwards than backwards.

So if the upper bone has slipped out into the armpit and the patient is still young or supple, at any rate if the sinews are not very powerful, it is sufficient to have him held on a stool; one of the two assistants is directed to press gently upon the head of the blade-bone, while the other stretches the forearm; then the surgeon seated behind thrusts one hand into the point's armpit, presses the bone up with this hand, and with the other presses the elbow to the side. But for a more powerful patient, with stronger sinews, a wooden board is required, two fingers thick, and lon enough to reach from the armpit to the fingers; the upper end is rounded and slightly hollowed to admit a small part of the head of the humerus. In three places in this, with a space between, are two slots through which soft straps are passed. And this board, covered with bandage to avoid injury by contact, is so applied from the forearm to the armpit, that its upper end is put under the armpit: it is then tied to the limb by its

straps, one just below the head of the humerus, the second a little above the elbow, the third short of the wrist, to which purpose the two spaces between the six holes are adapted. The limb so fixed is passed over a rung of a poultry ladder at such a height that the patient himself cannot stand firmly; and whilst his body is allowed to sink down to one side, the limb is stretched on the other side; and thus it comes about that the top of the humerus is forced upwards into place by the top of the board, sometimes with, sometimes without a sound. It is easy to learn that there are many other methods by reading Hippocrates alone, but no other has met with more approval in practice.

But if the humerus is put out forwards, the man is laid on his back and a bandage or a leather strap passed under his armpit, the ends of which are handed to one assistant behind the man's head and his forearm to another assistant; and it must be arranged that the former pulls the strap, the latter the forearm. Then the surgeon should thrust back the man's head with his left hand, whilst with his right he raises the elbow together with the upper arm and forces the bone back into place; and reduction is easier in this case than in the previous one.

When the bone has been replaced, the armpit is filled with wool; if the bone had moved backwards, to prevent it from slipping back; if forwards, to make the bandaging more effective. Then the bandage must first pass under the armpit and control the head of the bone, then stretch across the chest under the opposite armpit, next over the shoulder-blades and again back to the head of the same arm-bone,

and it is to be carried round several times in the same way until bone is well held. The bone when bandaged in this way is held in place more comfortably if it is also bandaged close to the side.
