It was then that I saw her, and, as I feared to disturb the family harmony by suggesting that the whole trouble was a bunion and flatfoot, I compromised by saying that, while there might be some gout, there was undoubtedly flatfoot, and if she would wear the proper sort of shoe and stop limiting her diet so strenuously, and cease suggesting to herself that she had a progressive gouty affection that would lead to deformity and decrepitude, she would soon be much better.
It required tact to make her look favorably on this advice, after all that she had gone through during months of limited diet and enforced exercise. Though not quite convinced, she was ready to try the new method. She began to be better as soon as she was fitted with a pair of shoes that supported her arch and as soon as her increased nutrition began to make itself felt. At the end of two weeks she was able to give up the remedies for constipation that she had been using for nearly a year, while at the end of four weeks she had regained ten pounds of weight and felt much better.
Several years have passed since I saw her professionally and occasionally I hear from her only to be told what a great measure of relief it afforded her and how much better she has been as a consequence of a few simple directions with regard to her feet. I have seen at least a dozen of cases of so-called gout in educated people which followed almost exactly the same course and yielded promptly to the same treatment. The hardest symptom about these cases to cure is the cherished mental conviction that they are the victims of constitutional disease, either gout or rheumatism, to which all their symptoms are attributed. They are cases for psychotherapy more than any other form of therapeutics and need for a considerable period to have repeated assurances of the entirely local character of their affection.
Bunions and Flatfoot.—The etiology and preventive treatment of a bunion has always seemed to me to bear a closer relation to a flat foot than to anything else. The flatfooted man has nearly always a tendency to bunions. The [{417}] explanation of this is not difficult if one traces the relation between the tendons that run around the arch to the big toe. The usual etiological explanation, however, is that in youth short shoes were worn which initiated a tendency to divert the big toe inward toward the other toes. But there are many reasons against this explanation. Anyone who tries will find that it is practically impossible to wear shoes that are so short that the big toe is crowded back. Women are more apt to shorten their shoes than men, yet women suffer both from flat feet and from bunions much less than men. The reason for this seems to be that the forward position with the elevation of the heel of the shoe supports the arch and gives the shoe a shape more fitted to the normal foot than is found in the masculine flat-heeled shoe. Besides, this form of shoe maintains its shape better, and then, too, women are not so prone to wear old so-called comfortable shoes as are men.
The mechanism of the formation of the bunion in many cases seems to be, that the large toe, instead of lying straight along the inner edge of the foot, is pushed or pulled toward the other toes. If this process began from the wearing of pointed shoes, especially if such shoes did not have a straight line on the inside, conditions within the foot would soon tend to emphasize it. If the adductor hallicis once gets the habit of contracting rather strongly, as it is likely to do through the irritation set up by the yielding of the arch, it will be hard for its opposing muscles to counteract it. More important than this, however, is the fact that the tendon of the flexor longus hallucis runs along the inner border of the foot and is particularly affected by the yielding of the arch. For it works at a decided mechanical disadvantage under the new conditions and is stretched in such a way as to pull forcibly and constantly upon the big toe, necessarily turning it more and more outward as the arch continues to yield. The dropping of the arch makes the distance from the heel to the toe longer than before and the tendon pulls the toe as far outward as possible to compensate for this, as the distance to its insertion is thus made somewhat shorter.
The yielding of the arch lengthens the foot and puts the tendons of all the flexors on the stretch. All of them have a tendency to bend the toes, and as this action is constant, gradually the tendons of the extensors become over-stretched and these muscles are not capable of exerting their full force in overcoming the action of the flexors. The flexor longus digitorum has a tendency to cause a bending of the small toes, and as it also runs across the foot it pulls the toes somewhat inward, that is, toward the big toe. This crowding leads to hammer toes and over-riding. The big toe, however, is maintained in a state of extension by its firm, full contact with the sole of the shoe and with the floor when walking barefoot. The one direction in which it can yield rather readily is outward toward the other toes because this shortens the distance between the end of the toe and the heel. The pressure put upon the flexor longus hallucis will have a tendency to cause this, for it is over-stretched by the yielding of the arch and keeps constantly pulling on the big toe until that member has a distinct flexion outwards.
This makes the metacarpo-phalangeal joint prominent and then nature proceeds to protect it by a water cushion, a special bursa due to the formation between layers of connective tissue of a pocket in which some serum is constantly present. One can scarcely admire enough this provision of nature by [{418}] which she protects prominent bony points whenever they are subject to much irritation or to such use as would cause injury to important structures below. If continued pressure continues to be irritating, however, the water cushion proves unavailing and an inflammation of the overlying skin occurs with occasionally a spreading of infectious agents from the surface into the serum pocket below. This serum is such a good culture medium that an acute abscess is likely to form—the acute bursitis of the surgeons.
Rarer Foot Troubles.—Besides bunions, a number of other deformities of the feet occur as a consequence of the yielding of the arch. All the toes are likely to bend rather acutely, and the points of them are pressed against the shoe, while the knuckles, so to speak, are made prominent and are more likely to be subject to corns than would otherwise be the case. Besides, the displacement of the big toe toward the little toes leads to a crowding of the toes together, and this gives rise to soft interdigital corns and to a lowered resistive vitality which may be the predisposing factor to slight infections of various kinds that will make the patients miserable. Such affections may appear negligible, a matter for the chiropodist, and not deserving the physician's attention; but they mean so much for the comfort of the patient and the prevention of exercise through sore feet reacts so deleteriously on the general health that these minor ailments become important and merit careful attention. Dr. Emmet tells the story of the old family servant, always grumpy and complaining, who, when he had the many blessings of life pointed out to him, confessed that the Lord had been very good to him, but said, "The Lord knows He takes it out of me in soft corns."
Hammer Toes—Clam Toes.—Nature has provided a wonderful mechanism in the arch of the foot and the anatomical relations of the toes to support the weight of the body firmly, gracefully, and comfortably; yet any yielding of any part of it leads to a disturbance of its delicate mechanical relations and, consequently, to ever-increasing deformity. Hammer toes are typical examples of what such a disturbance may lead to. One of the toes becomes pressed downward between two others. This over-stretches the extensor muscles and tempts the unbalanced flexors to contract. As the extensor muscles become, after a time, unable to work in the constantly bent toes, they atrophy to some extent and then the flexor muscles pull the toe farther and farther down until there is no possibility of its being straightened at all. Now, if the flexor tendons are cut and the toe straightened the atrophic extensor muscles will not hold it in that position, and when the flexors grow together the old condition will reassert itself. In the meantime, muscle changes in the neighboring toes have also taken place. With no resistance on one side of them, they become bent sidewise over the hammer toe, and so their muscles on one side are overstretched and on the other side become contracted. After a time it is impossible to correct this series of deformities which are being constantly increased and emphasized by the weight of the body above.
Present-day Shoes.—In recent years we have heard much more than heretofore about foot troubles. As the old-fashioned shoes were carefully made by skilled shoemakers to fit the feet of one individual and not to conform to some supposed ideal pedal extremity, they supported the feet much better than do the modern cheap machine-made shoes. These custom shoes lasted a long time, and, after they were once molded to the foot, the wearer was not [{419}] disturbed for many months by the process of having to become accustomed to another shoe. The many advertisements in quite recent times of foot powders and other artificial relief for the foot show that people are suffering much more than before, or, at least, are less able to bear the discomfort. These powders, however, are not likely to do good in the long run, since they tempt the wearers to stand the discomfort against which they do furnish a certain amount of soothing. It is much better, however, for the sufferer to find the cause of the discomfort and to remove it if possible, for otherwise it will lead to constantly growing displacement of bones and muscles and may eventually even bring on actual and ever-increasing deformity.
