Foot (anatomy)

“ Any mechanical displacement of one bone throws not only all bones out of harmonious working order but also disarranges their accompanying muscles and the nerves attached to them, resulting in inefficient action and in radiating pains. The fleshy parts of the foot are at the sole, ball, on the bottom of the heel and along the outer border and they play the part of protection where it is most needed. The bottom flesh forms pads in walking and supporting the body, insuring springiness and lessening the jar which is incidental to locomotion. ”

“ Supposing these to represent the bones of the great toe and its metatarsal bone—which, in their normal position, are on the same line—we can see that if the toe bones a are bent toward the other toes first, and then pushed backward, it necessarily forces out the joint in the only direction in which it can bend, which is inward. The greater and more constant the pressure against the end of the toe by the short boot or shoe, the larger the joint, and the more it will project from the inside of the foot ”

“ The heel strikes the ground with great force, as the wear of our boots and shoes in that part shows us. But the projecting heel of the human foot is the arm of a lever, haying the ankle-joint as its fulcrum, and, as it strikes the ground, brings the sole of the foot down flat upon it, as shown in figure 1. At the same time the weight of the limb and body is thrown upon the foot, by the joint effect of muscular action and acquired velocity, and the other foot is now ready to rise from the ground and repeat the process we have traced in its fellow. ”

“ But perhaps the most absolutely distinctive character about the muscles of the foot is the existence of what is termed the 'peronaeus longus', a long muscle fixed to the outer bone of the leg, and sending its tendon to the outer ankle, behind and below which it passes, and then crosses the foot obliquely to be attached to the base of the great toe. ”

“ Any active boy of twelve could give him points and a beating in a race for life in the open. Further, his foot shows a much larger propor­tion of the whole foot in front of the end of the great toe than is ever seen in man. The ligaments which bind the joints of his foot together, while the muscles play upon them, are little different from those he will require for the girders of his arch, except for such a throwing out of slips, and shifting under the stresses and strains of such walking as his new gait involves. ”

“ In addition to these evils arising from the pointed heeled boot, there are yet two more. In the first place, the elastic spring of the arch being broken by the heel, the vibration produced by its contact with the earth, at every step, causes a concussion which extends along the whole of the spinal column, and is sometimes very acutely felt. In the second place, the expanse of the foot being limited, the seizure of the earth by the foot is incomplete both in standing and in walking, so that it becomes a new art to learn how to stand erect or to walk with safety. ”

“ The great toe is usually twisted towards the median line, and the joint consequently has an ugly knotted appearance: all five toes are crushed together, and lose their natural shape, while the last, and often the last but one, is altogether distorted and deformed. Nor is the mischief confined to the toes: the whole foot, so seldom exposed to the open air, has a dry, lean, ill-nourished look. ”

“ When the feet are left bare the complex muscular apparatus of the extremity, which in a stiff shoe scarcely works, is called into vigorous action, the arch of the foot plays with every step, and each toe performs its share in the act of progression. ”

“ We have heretofore endeavoured to show what is the true, normal shape of the healthy foot, as recognized by science, art, and common sense; that in it the toes lie directly forward of the metatarsal bones, in the same line, having plenty of room for all of them to come to the ground, or the surface on which they tread; that there is no occasion for grown-in-nails, big joints, or corns until after the adoption of false habits in the manner of the foot’s clothing ”

“ The back of the foot will rub the knee if that be attacked, whilst if the foot be cut away, the stump will make ineffectual movements, and then, in many frogs, a pause will come, as if for deliberation, succeeded by a rapid passage of the opposite unmutilated foot to the acidulated spot. ”

“ The foot is naturally a beautiful organ; why should it not be allowed to retain its beauty? The foot is generally said to have three chief parts—the tarsus and metatarsus, which form the arch of the foot, and the toes. These parts are made up in all of twenty-eight bones, all of which are well supplied with muscles. The foot is therefore by nature a very mobile organ, and those who have been deprived of the use of their arms have found that with their feet they could perform those actions for which we employ our hands. ”

“ High and narrow heels give an insecure hold of the ground, and throw the weight, which ought to be distributed over the sole, forward on the front part of the base of the toes. This unnatural position, besides rendering the risk of sprained ankles much greater, stretches the fibrous bands which bind the various and complicated bones of the instep into a beautiful arch, strong yet springy. The tough fibres yield, the foot flattens, elasticity and grace of movement disappear to a large extent, and aching pains are complained of. ”

“ When the foot is in its best shape this part is elevated and prominent, with a well-marked and graceful rise from the ball upward, and a distinct projection or convexity at its upward portion, or about half way between the joint and the ankle, which is the upper surface of the first cuneiform bone, or the point where that bone joins the first metatarsal. This place is subject to callosities or thickenings of the skin, resembling corns, but more frequently is affected by soreness without any thickening of the skin. ”

“ It is true, that when the toes are covered with their soft parts, the second toe appears a little longer than the first, and this appearance, emphasized and exaggerated, is perhaps responsible for a practical assumption that Nature intended an even-sided, tapering foot. On the contrary, the natural foot gradually expands in breadth from the instep to the toes and, in the skeleton itself, the great toe is the longest. ”

“ The examination of the foot proves that it is one, and not a hand, for bone for bone it may be compared [Pg 221] with the human foot, and that of the Apes. The great toe is wide apart from the others, and in that it resembles the thumb of a hand; but all the other bones of the ankle or tarsus are in the same relative position as they occupy in us. ”

“ DISREGARDING the action of those parts not affecting the feet, the act of walking may, as I think, be thus described: The foot put forward should reach the ground when nearly flat; the toes, the organs of feeling, should be the first to reach it, not the heel, which could not be without some concussion, however slight. The heads of the metatarsal bones and the toes are then pressed firmly against the surface. The great-toe, having only two phalanges, is held down in its whole length, the flexor tendon being attached to the final phalanx close to the joint between them. ”

“ The nature of the cause here spoken of seems to be like that of a sprain, to a slight degree, and may be an influential one, but we doubt that it is the most common cause of that loosening of the ligaments which allows the foot to break down. The most common and efficient of all the causes of this difficulty, it appears to us, is the short heel which has always been worn on boots and shoes, and is still, except where an innovation upon its shape has been made within a few years past. ”

“ The exciting cause, or that which called her attention to her foot, was the alleged slipping of the tendon of the peroneus longus muscle where it passes under the outer ankle-bone. She had no theory, fancy, or any other sentiment regarding her lameness whatever. She simply dropped her toes when walking, and was obliged to lift that limb very high to advance the foot and prevent stumbling. When, in examining her, I asked her to raise the foot, she was unable to do so. The muscles moving the ankle-joint were powerless. ”

“ It arises by the outer fibres of the common extensor muscles of the toes being separated. In all the anthropoids the feet are so articulated at the ankle-joints that the soles are directed towards each other, and only the outer edge of the foot comes to rest on the ground when the animal tries to stand. The feet have a tendency to assume a similar position in children at birth. The advantage of a muscle, such as the peroneus tertius, is apparent in the human foot, for it tends to raise the outer border of the foot, so that the sole is properly applied to the ground. ”

“ The discomfort, however, will rapidly disappear if rational foot-gear is worn for a time, as the muscles will regain their natural and proper action. Raising the heels diminishes the leverage by which the balance of the body is maintained, and the higher the heels the greater is the risk of falls and sprains, and the greater the distortion of the foot. ”

“ The four smaller toes are bent under the foot, and the instep is forced upward and backward. The foot therefore assumes the shape of an acute triangle, the big toe forming the acute angle and the other toes, being bent under the foot, becoming almost lost or absorbed. ”

“ Flat-foot is occasioned by the loosening of the ligaments that knit the foot firmly together, and, by the consequent sinking of the arch, the inner aspect of the foot no longer presents the natural hollow in the sole. The causes of such loosening of the ligaments are numerous, but by far the most frequent, and one readily induced by the ordinary shoe, is weight improperly directed on the arch. ”

“ Movements of the foot must be employed, such as inward and outward flexion, twisting the whole leg from the hip, and many others, calculated to strengthen the left leg, hip, and ankle.”
[7] As a matter not wholly out of place, it may be said that the graceful walker stands upright, and in taking a step uses the muscles and joints of the hip, the knee, and the toes. Many people use the toes but very little, and their step lacks spring, elasticity, life, and grace; while others do not use the muscles in front of the hip enough, and their walk has no dignity. ”

“ His toes form the front part of his foot and the bones of his foot run not only back but up. Underneath these bones at the back of his foot is a gelatine-like substance, which is a much more effective shock absorber than rubber heels or any other device. ”

“ For about two years the foot aches continually, and is subject to a constant pain, like the pricking of sharp needles.” Finally the foot becomes reduced to a shapeless mass, void of sensibility, which “has now the appearance of the hoof of some animal rather than a human foot, and affords a very insufficient organ of support, as the peculiar tottering gait of those possessing it clearly shows.” ”

“ The disease is confined almost exclusively to the fore feet, because of the greater weight which they support, and because the heel of the fore foot in action first strikes the ground and thus receives much more shock or concussion than the heel of the hind foot, in which the toe first makes contact with the ground. ”

“ This process over, if he still feels pain in the lower extremities, his foot is buckled upon an iron sole which oscillates in any direction according to its method of connection with the power, from side to side, so as to twist the leg about forty-five degrees each way, up and down, to imitate the trotting of the foot, or with a motion which combines several. A variety of other apparatus gives play to other muscles ”

“ In the slightest degree of affection of the foot, the great toe is drawn a little away from the other toes; in severer degrees the toe is drawn away still further, and the whole foot is forcibly bent upon the ankle, and its sole directed a little inwards. ”

“ The toes naturally lie straight forward in the line of the foot. Few persons in civilized nations, however, have naturally formed feet. The big toe is crowded upon the others, while crossed toes, nails grown-in, enormous joints, corns, and bunions abound.
THE CAUSE OF THESE DEFORMITIES is found in the shape and size of fashionable boots and shoes. The sole ought to be large enough for full play of motion, the uppers should not crowd the toes, and the heels should be low, flat, and broad. ”

“ But the toes, or digits of the foot, are far shorter in proportion than the digits of the hand, and are less moveable, the want of mobility being most striking in the great toe—which, again, is very much larger in proportion to the other toes than the thumb to the fingers. In considering this point, however, it must not be forgotten that the civilized great toe, confined and cramped from childhood upwards, is seen to a great disadvantage, and that in uncivilized and barefooted people it retains a great amount of mobility, and even some sort of opposability. ”
