Of the OBLIQUITY of the Uterus.

By the obliquity of the uterus I mean its untoward situation. For either the uterus preserves its natural direction, or does not preserve it. Where the uterus preserves it, I call it well placed: the point of it is turned directly to the cavity of the pelvis, and the fundus uteri is suspended in the space between the umbilical region and the vertebræ: if the uterus does not preserve its natural direction, if it inclines too much forwards, backwards, or towards either the right or the left side, I call it oblique, or untowardly placed. All the other situations of the uterus are reducible to these four, from which they differ no otherwise than as its line that should naturally be perpendicular to that of the vagina deviates more or less from it towards any of them. It is from this obliquity, greater or less, that proceeds, by much the most often, the greater or the less difficulty of the lyings-in.

It would be superfluous here to analise all the causes of such obliquity, because, being mostly natural ones, there is no preventing them. But there are some causes of it, or at least, that appear to me to be sometimes the causes of it, that it cannot be improper for me to premise here, for precaution-sake.

I have then some reason to think, that both here and in Holland the stays contribute much to the obliquity of the uterus. For though women, during their pregnancy, may perhaps wear them looser than at other times; yet their natural hardness pressing on the belly, with the stiff whalebones, always too many if there are any at all, cramp the fœtus and the womb, to which the stays too often give a bad situation, according to their motion or swagging more to one side than to the other, in their state of looseness; and if they were laced tighter, that would be yet more dangerous.

I could wish then, that women with child would either content themselves with wearing a bodice only, or stays without any whalebone, but at the back just to serve the loins, and even those not to come so low down as I have seen some. The obliquity of the uterus is much rarer in France than it is here, for which I cannot account otherwise, than from the women there avoiding any prejudice from their stays, during their pregnancy. There is another cause, as I apprehend it, of the lateral byass, which is the lying too constantly on either side, whence the uterus contracts a habit of inclination to that side. The probability of such an effect I submit to the anatomists, as I speak here only conjecturally, and not with the presumption of certainty.

The obliquity of the uterus may be discerned from the difficulty there will be, in touching, to come at its orifice. And it is by touching alone that you can hope to discover which way its deviation points, whether it is placed too high towards the os pubis, too much turned towards the curve of the vertebræ, or in a lateral direction, towards either the right or left ilion. But which ever way that mis-direction points, the difficulty of the delivery is proportionable to the degree of it: and the skill and knowledge of the midwife in not only the reduction, but the keeping of the uterus to its due position, till the delivery is accomplished, form one of those principal branches of the art, for which the gentlemen-midwives must be naturally so unfit.

There are very few authors who have treated of this obliquity of the uterus. Some do not mention it at all, others speak of it, but so slightly as to escape attention.

Dr. Smellie in his enumeration of the cases, by which laborious labors are occasioned, which he ranges under seven heads, has intirely omitted this case of obliquity. He has bestowed indeed a whole chapter on the distortion of the pelvis, a case I take to be comparatively infinitely rarer than an obliquity of the uterus. He might as well suppose a frequent vitious conformation of the cheek-bones, as of those that form the pelvis: which, were it so, must necessarily imply a constant recurrence of hard labors in the same woman, which is not often the case. Whereas the liableness of the uterus to an obliquity from various accidents, principally accounts for the easiness of one labor in a woman, being no argument for her not having a hard one in future, or convertibly. I dare aver then, that in the course of my practice, which is not the least extensive one, this very case of obliquity has occurred to me oftener than all the others put together, and indeed caused me the most pain to remedy or conquer. Why then such an omission by these writers? I cannot conceive, unless that they were aware of the consequence, obvious to be drawn from thence, that women, by the superior fitness of their hands, must be the properest to apply the topical remedy; and that their iron and steel instruments could not so well be set to work in such a case, at least in due time. This is absolutely so true, that in the case of this very obliquity, which occasions most of the very lingering labors, for which the midwives, who have not preventively exerted themselves to reduce it, and thereby to clear the passage for the fœtus, have no remedy but patience; those very lingering labors, I say, which shall have thus arisen from the want of skill or prevention, furnish the men-practitioners with a pretence to dispatch them with their instruments. Thus they, often murderously for the child, and injuriously to the mother, terminate many a delivery, which a gentle and constant reduction of the uterus would have so much more safely and less painfully accomplished. And how accomplished? evidently not by any violence to Nature, but purely by redressing the wrong she is in, oftenest not by her own fault, but by some adventitious cause, in which she has been rather a passive sufferer than originally herself deficient. A justice this of distinction too often refused her, and from which too many errors of practice arise, perhaps in more cases than this.

However, this is certain, that this case of the obliquity of the uterus deserves much more notice and attention than have been paid to it. It is one of the most important difficulties of the art.

He who treats the most at large of this matter is Daventer, who, I have strong reasons for believing, first took the hint from some midwife: but a hint, which the usual imperfection of the manual function in men hindered him from duly improving. For in the way he sets forth the different inclinations of the uterus, and the methods of rectifying them, instead of throwing a practical light upon the subject, he has obscured it with errors, absurdities, and repetitions without number or excuse.
