The cause of the spasmodic action in the muscle is sometimes apparent, sometimes very difficult to be detected. Sources of irritation at the extremities of neighbouring and communicating nerves are to be looked for and removed; and the spasms are to be moderated, as much as possible, by external and internal remedies. Opiate frictions, and the application of the nitrate of silver over the course of suspected nerves, are sometimes followed with benefit, and may be accompanied by the internal administration of antispasmodics, though the efficacy of these is often doubtful. When the head has been for a long period, perhaps many years, turned to one side, from any cause, the muscle on that side naturally becomes shortened, and a change takes place in the form of the bones. If the patient is still young, the deformity may, in a great measure, if not entirely, be remedied. Division of the shortened muscle was a favourite operation of old surgeons for the cure of wry-neck, and may be resorted to with advantage in some cases. One of the heads, or both, may require to be detached from the sternum and clavicle. It is only in cases where the muscle is in fault, it being shorter than usual, that benefit can be expected from this proceeding. It is a very simple operation, and can be effected by a mere puncture of the skin betwixt the two portions. By the cautious use of a blunt and flat probe or director, the cellular tissue under the origins of the muscle is separated; this is followed by a narrow and blunt-pointed knife, by which the attachments to the clavicle and sternum are cut across.

Distortion of the neck is most frequently produced by some vice in the bones, as curvature, from softening, attended with deformity of the trunk or of the limbs. In such cases, the twist is generally to the right side, the ear approaching the shoulder. No treatment can be effectual, unless the other curvatures are corrected; for the head is placed so to preserve the equilibrium of the body. The head is to be supported, and its weight removed from the vertebral column by a curved iron rod, attached to the back of stays fastened on the loins, leathern straps passing from the top of the rod under the chin and over the occiput. By the use of such apparatus for a considerable time, the vertebral column may regain its perpendicular direction, and all deformity of the neck be consequently removed. The application of such a machine is required after the division of the sterno-mastoid, so that the head may be kept straight until the muscle is reunited of a proper length, and any change in the form of the bones may be got over. In slight cases, this treatment is not required; on giving support to the trunk, and raising the shoulders to an equal level, the muscles of the back, perhaps stimulated by powerful and repeated friction, gradually bring the column into its proper form. Then the position of the head to one side is no longer required to balance the body. But a cure can be expected only when no material change has taken place in the form of the individual bones.

Excurvation of the cervical vertebræ,—bending of the head forwards, and perhaps a little to one side, generally to the right,—takes place as a consequence of disorganisation of the ligaments and connecting fibro-cartilages of the vertebræ, with subsequent ulceration of the bones. The disease generally occurs in the superior vertebræ; in the articulation of the atlas with the occiput, or with the vertebræ dentata, or in the articulation of the latter with the one below. The articulations on the left side are usually affected first. There is stiffness, pain, and swelling of the soft parts covering the affected bones, attributed perhaps to exposure to cold, as when sitting in a draught, and supposed to be merely crick of the neck. The posterior cervical muscles are weakened, and the head is bent forwards. The patient is unable to support his head by the usual muscular action, and when in the erect position places his hands on the temples, to prevent it from dropping, and to keep it steady. Difficulty of swallowing is a prominent symptom from the first, as can readily be imagined when the close application of the constrictors of the pharynx to the forepart of the affected bones is kept in remembrance. The position of the head also renders deglutition awkward. The disease is attended with great suffering, evinced by marked anxiety of the countenance; and the pain is most violent during the night. The complaint is too frequently trifled with at the commencement, being not understood, nor its danger appreciated. The swelling increases, with pain, and the chin falls down on the sternum. The patient grows emaciated, and perhaps becomes weak in the lower limbs, and even in the upper; the feces and urine are imperfectly retained. Occasionally, abscess forms behind the upper part of the pharynx, increasing the pain and the difficulty of deglutition. On making an examination through the openings by which the abscess has emptied itself spontaneously, the bone is felt bare; and portions, even large, of the vertebræ, or vertebra, are, after some time, discharged, so as to expose the theca of the spinal cord. Even in such circumstances patients have lingered on, and that for so long a period as to allow of some unprincipled fool advertising a perfect recovery.

The termination of caries of the cervical vertebræ, often without any appearance of abscess, is in general fatal and sudden. The head, slipping from its support, falls forwards or to a side, causing immediate and complete paralysis of the whole body; dissolution soon follows. On examination, the articulating surfaces of the vertebræ are found displaced, and the shreds of ligaments which connected them ruptured. The atlas is separated from the occiput; or the processus dentatus, escaping from its situation, in consequence of destruction of its confining ligaments, is found compressing the medulla oblongata. This process is very often destroyed almost entirely, or it is so far detached by ulceration at its root as to be easily broken off. The disease in general seems to commence in the articulations, whereas in the vertebræ with larger bodies, abscess and ulceration have their foundation and origin more frequently in the deposit of tubercular matter in the cancellated texture of the bones. In other instances, the termination may be more slow and gradual; the patient is worn out by long suffering and continued purulent discharge; change of structure takes place in the theca vertebralis, or in the medulla itself; serous effusion occurs at the base of the brain; the patient’s sensations are blunted, and he loses the use of his limbs gradually; his intellects fail, and coma supervenes, followed by death.

Active and early interference can alone arrest, subdue, or prevent the dreadful consequences of the disease above described; it is quite intractable in its later stages. Confinement to the recumbent posture, and strict rest of the affected parts must be enjoined; and blood is to be abstracted locally, once and again, according to circumstances; afterwards counter-irritation is to be employed, and repetition of moxas or of caustic issues is the most efficacious. When the painful feelings have subsided, and some impression has been made on the disease, the patient appearing to convalesce, the head must be supported by a proper machine for a long time. He will thus be enabled to use his limbs, to move about, and repair his general health, the weight of the head being taken from the weakened column.

The External Jugular vein may require to be opened for the abstraction of blood in affections of the head; or when venesection

cannot be readily performed at the bend of the arm, from the small and indistinct condition of the veins in children, or in people loaded with fat. The vein is made to rise by pressure with the finger or thumb, as seen in the accompanying cut, above the clavicle. The lancet is passed though the integuments and platysma myoides into the vessel, midway between the jaw and clavicle. After a sufficient quantity of blood has been withdrawn, the pressure below is removed, and the edges of the wound are put together with a bit of court plaster, or by means of a compress and bandage lightly applied.[41]

Ligature of the common Carotid may be required for the cure of aneurism at the angle of the jaw; or on account of hemorrhage from deep wounds in the same situation, when, from any circumstances, the divided extremities of the vessels cannot be secured. A deep incision of the angle of the jaw, towards the base of the cranium, not only divides important branches of the carotid, but may also wound the vertebral arteries where they project in a tortuous fashion, betwixt the dentata and atlas, or betwixt the latter bone and the occiput.

Ligature of the common carotid has been had recourse to, in order to stop bleeding from the mouth, nostrils, and other parts connected with the face,—for the cure of large or deep-seated aneurism by anastomosis,—and as a preliminary step to the removal of large and firmly attached morbid growths of the face or neck. This last proceeding, as already remarked, does not in any way enhance the patient’s safety, whilst it adds much to his suffering.
